Recent studies indicate that this scenario might have been a feasible existence for several moons within our solar system. None of the moons in our solar system possess rings today. But a new study indicates that such rings, if created, could remain stable for a million years, even while being gravitationally pulled by other solar system objects. The findings deepen the mystery of why these satellites are now ring-free. Rings surround many members of our planetary family. Saturn is perhaps the best-known example, swathed by eight main rings made of thousands of smaller ringlets, but the other three outer planets also possess rings, the Voyager space missions revealed. Composed of chunks of ice and rocks of varying sizes, these ring systems are maintained by small shepherding moons, whose gravitational forces tug the chunks and tweak their positions. More recent studies using ground-based telescopes have revealed rings encircling several centaurs — asteroids beyond Jupiter’s orbit — and minor planets, including the egg-shaped Haumea. Even Earth and Mars may once have had rings. However, no study so far has definitively spotted rings around any of the solar system's 300-odd moons. (A 2008 study claiming that Jupiter's moon Rhea possessed a ring turned out to be a false alarm.) This absence is all the more intriguing because the physical processes that create rings can theoretically occur on both planets and their satellites. A ring can form around an object when debris starts orbiting it, said Matthew Tiscareno, a planetary scientist at the SETI Institute in Mountain View, California. This debris could be kicked up from the body's surface following an asteroid or comet collision, or may consist of icy plumes ejected by powerful cryovolcanoes. Over time, gravitational forces along the body's equatorial bulge flatten out the debris into a ring, Tiscareno told Live Science in an email. But lots of moons have suffered asteroid impacts or have cryovolcanoes — and yet, they remain ringless. The search for the elusive lunar rings These observations prompted Mario Sucerquia, an astrophysicist at France's Grenoble Alpes University, and colleagues to investigate whether moon rings could be stable at all. A 2022 study Sucerquia co-authored found that theoretically, isolated moons could have stable rings around them. But that study didn't consider the gravitational effects of other moons and planets. To investigate this, in the new study published Oct. 30, 2024 in the journal Astronomy and Astrophysics. Sucerquia and colleagues selected five sets of spherical moons and their neighboring planets, including Earth and the moon. For each set, the team added rings to all the satellites, then simulated how the rings would behave over a million years, while being pulled gravitationally by their parent moon, other nearby moons and the planet. The researchers also calculated how chaotically the ring particles moved over a millennium, to determine the rings' stability. The researchers expected to find that the rings were unstable, but the model showed that, barring a few moons, including Saturn's "Death Star" moon Mimas, these moon rings were stable — particularly Jupiter’s Iapetus. Even Earth's moon had a 95% chance of supporting a stable ring system in the simulations. Sucerquia shared with Live Science via email, "[W]e were not expecting that moons situated in a challenging gravitational setting, influenced by numerous other moons and planets, would be able to preserve stability in their rings." He added, however, that "instead of obliterating the rings, these harsh environments have enhanced their beauty by forming intricate structures such as gaps and waves, akin to what we see in Saturn's rings."

So why don't the moons have rings today? The authors suggest that non-gravitational factors, including the sun's radiation and charged particles from the magnetic fields of the moons' parent planets, caused any previous rings to disintegrate. There are differing opinions regarding the conclusions of the study. Tiscareno, who did not participate in the research, believes that over time, the rings were probably disrupted by the gravitational forces exerted by the moons that orbit the planet. "Because most solar system moons rotate very slowly (keeping the same face towards their planet as they orbit, as our moon does to Earth), any ring particles must be orbiting the moon much faster than the moon spins," he said. So gravitational tugs from the parent moons, over long stretches of time, would "cause the ring particle orbits to decay until they eventually impact the surface of the moon," he said. In other words, if our moon ever had rings, they crashed to the lunar surface long ago.

2025-03-20 13:48:27

View pictures in App save up to 80% data. In a groundbreaking discovery, NASA astronomers have unveiled an immense reservoir of water vapor surrounding a distant quasar. This cosmic oasis, located a staggering 12 billion light-years from Earth, contains an astounding 140 trillion times more water than all of our planet’s oceans combined. The finding not only reshapes our understanding of the early universe but also raises intriguing questions about the prevalence of water in cosmic structures. Revealing the celestial oceanic realm The colossal water reservoir was detected in 2011, enveloping a quasar known as APM 08279+5255. This celestial powerhouse dates back to when the universe was merely 1.6 billion years old, offering a rare glimpse into the cosmos’ infancy. The sheer magnitude of water present in this ancient system challenges our perceptions of elemental distribution in the early universe. Quasars, among the most luminous objects in the universe, are fueled by supermassive black holes. In the case of APM 08279+5255, the central black hole is a behemoth, 20 billion times more massive than our Sun. This cosmic engine generates energy equivalent to a thousand trillion suns, creating a unique environment where water vapor extends across hundreds of light-years. The discovery of this vast water reservoir aligns with recent advancements in our understanding of cosmic phenomena. For instance, a seemingly trivial flicker of light recently revealed the source of a mysterious cosmic phenomenon, highlighting how seemingly minor observations can lead to major breakthroughs in astrophysics. Matt Bradford, a researcher at Nasa’s Jet Propulsion Laboratory, highlights the uniqueness of this environment in a study published in the journal Astrophysical Journal Letters: “The environment around this quasar is truly unique in its ability to produce this enormous mass of water”. This discovery confirms the prevalence of water in the universe, even in the most remote epochs. Features of the interstellar oasis The water vapor enveloping APM 08279+5255 displays remarkable traits that distinguish it from conventional galactic settings. These distinctive features arise from the powerful infrared and X-ray radiation produced by the quasar. Below is an overview of its extraordinary properties: Temperature: Approximately -63°C, five times warmer than average galactic conditions Density: 10 to 100 times higher than similar cosmic environments Extent: Envelops the quasar across hundreds of light-years The conditions of this cosmic oceanic realm are strikingly dissimilar to those found in our nearby galaxy. The intense environment generated by the quasar's radiation promotes the condensation of water to an extraordinary degree, providing a one-of-a-kind setting for examining the properties of matter in extreme conditions. While this discovery is monumental, it’s worth noting that advancements in space exploration continue to push boundaries in other areas as well. For example, China recently unveiled a hypersonic aircraft capable of circumnavigating Earth in just 2 hours, showcasing how our understanding of both cosmic and terrestrial frontiers continues to expand rapidly. Consequences for the development of the universe and the emergence of life The discovery of this massive water reservoir has profound implications for our understanding of cosmic evolution and the potential for life in the universe. NASA scientist Matt Bradford emphasizes that this finding proves water was already abundant in the very early universe, challenging previous assumptions about elemental distribution in cosmic history. This discovery illuminates the processes involved in the formation and evolution of galaxies, especially in extreme conditions. It indicates that the essential components for life, as we understand it, might have existed much earlier in the history of the universe than was previously believed. Investigating these water-abundant environments could yield vital information about the prerequisites for life to arise in the universe. Aspect Significance Water abundance Indicates potential for life-supporting environments Early universe composition Challenges theories of elemental distribution Galaxy evolution Provides insights into formation processes As we continue to explore the cosmos, discoveries like this remind us of the vast mysteries that still await us. From the depths of space to innovations closer to home, such as the most efficient and economical heating systems, science constantly pushes the boundaries of our knowledge. Prospective studies and investigations The identification of water vapor surrounding APM 08279+5255 was achieved using millimeter and submillimeter observations, which enable researchers to explore far-off and intricate settings. This significant advancement opens up new avenues for research, especially with the development of cutting-edge instruments such as the CCAT telescope, which is being built in the Atacama Desert of Chile. Astronomers are optimistic that these advanced instruments will lead to the identification of additional water sources in the early universe, as well as enhance the exploration of primordial galaxies. Such initiatives have the potential to transform our comprehension of the essential conditions for life and the core mechanisms that influence the formation of cosmic structures. As we delve deeper into the cosmos, it’s fascinating to consider how discoveries in space can influence our daily lives. For instance, certain winter drinks have been found to stimulate concentration and memory, showcasing how research in various fields can intersect to improve our understanding of both the universe and ourselves. To sum up, the identification of this enormous water reservoir located 12 billion light-years from us represents a remarkable achievement in our exploration of the universe. This finding not only enhances our understanding of the primordial cosmos but also prompts fascinating inquiries regarding the existence of water and the possibilities for life beyond our planet. As we delve deeper into the enigmas of the universe, we are reminded that the fundamental elements necessary for life as we recognize it are more widespread and ancient than we previously thought.

Ancient Climate Record Retrieved from Antarctic Ice Sheet Remains Intact

2025-04-03 16:40:02

View pictures in App save up to 80% data. The ice core extracted from Little Dome C. (PNRA/IPEV) A massive ice core sample extracted from Antarctica could hold the most ancient, continuous record of Earth's climate, extending over a million years into the past. If laid out flat, the complete length of the ice core, measuring 2,800 meters (9,186 feet), would stretch beyond the Golden Gate Bridge in San Francisco. Each meter-long segment contains up to 13,000 years of deep, compressed history, including bubbles of ancient air. Together, the evidence provides a baseline for our current climate crisis, and it could reveal more about past extreme climate change events that threatened human survival. "We have a strong indication that the uppermost 2,480 meters contain a climate record that goes back to 1.2 million years," says Julien Westhoff, chief scientist on the ground for the European Project for Ice Coring in Antarctica (EPICA). More analysis is required, but there is a possibility that the deepest sections of the drilling may hold ice from the pre-Quaternary era, which is over 2.5 million years old. View pictures in App save up to 80% data. A portion of the ice core. (PNRA/IPEV) The oldest ice uncovered in Antarctica so far dates back 2.7 million years, but Earth's movements pushed this ice into a shallower patch of frozen material, so it doesn't provide a continuous climate chronicle; it's more of a snapshot. Previously, the EPICA record for the oldest vertical ice core covered the last 740,000 years or so, and it was obtained in 2004. Ice cores are precious to scientists, because they trap particles, water isotopes, and bubbles of atmospheric gases, like carbon dioxide and methane. This allows researchers to reconstruct climates and environments in our planet's history. Recent drilling efforts in East Antarctica reveal information about a timeframe during which the Earth's glacial cycles unexpectedly extended, occurring between 900,000 and 1.2 million years ago. Some scientists suspect nearly 99 percent of early humans in Africa may have died out during this period of extreme cold swings, although that hypothesis remains contentious and is mostly based on modern genetic data. The newly retrieved ice core from Antarctica has the potential to uncover further insights into Earth's climatic changes during this period. Additionally, it is likely to validate the extent to which human-induced emissions have disrupted the planet's natural glaciation cycles. "This transition remains a scientific mystery, particularly regarding the role of greenhouse gases and ice sheet dynamics," Carlo Barbante, director of EPICA, told CNN. "This information allows us to grasp the complex connection between greenhouse gases and global temperatures spanning hundreds of thousands of years, extending now to 1.2 million years and potentially further." The extraction site of the recent drilling is called Little Dome C, in East Antarctica, and it was chosen because radar surveys revealed the presence of extremely thick ice here, layered like a cake, with a bottom that had not yet melted away. At 3,200 meters above sea level – high on Antarctica's central plateau – summer temperatures on Little Dome C sit around -35 ºC (-31 ºF) and often there are high wind speeds to contend with as well. Researchers at EPICA, including scientists from the British Antarctic Survey, had their work cut out for them. It took about 20 days just to deliver all their infrastructure and cargo to the site from a nearby research station. View pictures in App save up to 80% data. Storage of ice core samples. (PNRA/IPEV) As drilling commenced, an isotopic analysis system was capable of detecting glacial and interglacial cycles nearly instantly, with each segment of the ice core being retrieved from the earth. This is the reason why researchers at EPICA are making significant assertions so early in their study. Today, the Antarctic ice sheet holds 90 percent of our planet's ice. A drilling like this one, straight from its belly, could reveal just how Earth's southernmost continent came to hog most of its freshwater. Climate scientist Richard Alley, who was not involved in the recent drilling effort, told the Associated Press that EPICA's ice core was "truly, truly, amazingly fantastic." Alley forecasted, "They will discover amazing knowledge."

Recent studies shed light on the evolutionary reasons behind the development of saber-toothed predators' formidable teeth.

2025-04-08 03:38:53

View pictures in App save up to 80% data. Saber-toothed tiger (Shutterstock) Saber teeth – the long, sharp, blade-like canines found in extinct predators such as Smilodon – represent one of the most extreme dental adaptations in nature. They evolved at least five times throughout mammalian history and are a classic example of convergence, which is when similar structures evolve independently in unrelated animal groups. With no living representatives, scientists have long debated how these predators used their fearsome teeth, and why this extreme tooth shape evolved so often. Our new study, published today in Current Biology, provides an answer. We found extreme sabre teeth are functionally optimal, meaning their shape provided a real advantage as specialized weapons. Their slender and sharp forms were perfect for puncturing prey. However, this came at a cost: sabre teeth were also weaker and more prone to breaking. These discoveries hold significant value as they enhance our comprehension of the evolution of extreme adaptations in the natural world. Additionally, they provide valuable perspectives on optimal design principles that can be applied not only in biology but also in the fields of engineering and technology. Saber-toothed hunters throughout history Saber-toothed predators once inhabited various ecosystems worldwide. Fossil evidence of these creatures has been discovered across North America, Europe, Africa, and Asia. What sets them apart are their sabre-like teeth, a unique form of canine tooth. These teeth are elongated, pointed, flattened on the sides, and exhibit a curved shape. This contrasts with the shorter, sturdier, conical canines found in contemporary large felines like lions and tigers. View pictures in App save up to 80% data. Numerous extinct predators globally developed saber-shaped teeth that significantly differ from the teeth of today's large felines. Tahlia Pollock This legendary tooth predates the dinosaurs, having emerged approximately 265 million years ago among a category of mammal-like reptiles known as gorgonopsids. Over millions of years, saber teeth evolved repeatedly in different groups of carnivorous mammals, marsupial relatives like Thylacosmilus and “false” saber-tooth cats such as Barborofelis. The most well known saber-toothed predator is Smilodon. It persisted until just 10,000 years ago. You can look at a 3D model of one of these predators – Smilodon fatalis – below. This model has been digitised from a cast specimen from the Natural History Museum of Los Angeles County. Extensive studies of saber-tooth ecology have led to a widely accepted conclusion that these formidable predators mainly hunted large animals. They employed powerful neck muscles to execute slashing attacks aimed at the soft tissues of their prey's throat. It is believed that their specialized teeth provided a significant advantage in this regard, enabling them to effectively deliver a lethal bite. This concept is what we aimed to explore. Evaluating the balance between puncture resistance and strength In particular, we examined whether their shape achieved an ideal compromise between two opposing requirements concerning tooth functionality. On one hand, the teeth needed to be sharp and slender to effectively penetrate prey. On the other hand, they had to be sturdy and resilient to avoid damage or breakage. In order to explore this topic, we performed an extensive analysis involving over 200 various carnivore teeth, which encompassed both extinct saber-toothed species and contemporary animals. Initially, we assessed the three-dimensional structure of their teeth to compare saber teeth with those of other carnivorous species. Subsequently, we conducted two experiments to evaluate the biting performance of a selected group of these teeth. We created tooth models using stainless steel and inserted them into a gelatin block (which mimicked prey flesh) to assess the force required for puncturing. By utilizing metal replicas, we avoided any bending of the teeth throughout the experiment, thus guaranteeing precise measurements of the puncture force. We conducted engineering simulations to evaluate the stress levels experienced by various tooth shapes when subjected to biting forces. This analysis helped us understand their potential for fracturing. Ultimately, we performed an "optimality" assessment to identify which dental shapes provided the most effective combination of puncture efficiency and durability. A saber-toothed model created through 3D printing is being thrust into a gelatin block to assess the amount of force required for penetration. The most advanced forms of saber-tooth are the most efficient. Our findings regarding the shape of saber-toothed cats call into question the conventional classification of these predators into only two groups: the dirk-toothed, characterized by their elongated and slender form, and the scimitar-toothed, known for their shorter and laterally flattened appearance. Instead, we uncovered a continuum of saber-tooth shapes. This ranged from extreme forms, such as the long, curved canines of Barbourofelis, Smilodon and Hopolophoneus, to less extreme forms, such as the straighter, more robust teeth of Dinofelis and Nimravus. Our results reveal that the extreme saber-toothed forms, like Smilodon, were optimised for puncturing prey with minimal force. However, they were more prone to breakage under high stress. Less extreme saber-toothed forms, such as Dinofelis, were also optimal but in a different way. They struck a more balanced trade-off between puncture efficiency and strength. The existence of different saber-toothed species that developed distinct balances between puncture effectiveness and structural strength indicates a wider array of hunting tactics than was previously recognized. This finding aligns with an expanding collection of studies regarding their ecological variety. View pictures in App save up to 80% data. Morphospace’ (visualization of shape diversity) of sabre and non-saber-tooth canines showing areas of optimal performance. Miranta Kouvari & Melisa Morales/Science Graphic Design An eye-catching remedy These findings shed light on the repeated evolution of extreme sabre teeth, likely influenced by natural selection favoring an ideal design. Additionally, they may offer insights into the reasons behind their eventual extinction. Their growing specialization might have functioned as an "evolutionary ratchet," enhancing their efficiency as hunters while simultaneously rendering them more susceptible to extinction when environmental shifts occurred and their food sources dwindled. Our research offers valuable perspectives on the evolution of extreme adaptations in various species. By combining biomechanics with evolutionary principles, we gain a clearer understanding of how natural selection influences organisms to excel in specific functions. The sabre-toothed design showcases an impressive approach to a core mechanical problem, achieving a balance between effectiveness and durability — a principle that is similarly seen in tools created by humans. The balance between sharpness and durability is a crucial factor in engineering, impacting the design of a wide range of tools, including surgical scalpels and industrial cutting blades. Engineers creating precision instruments like hypodermic needles or advanced cutting tools can draw inspiration from nature's evolutionary designs, utilizing the same principles that influenced the development of these ancient predators.

If you happen to be reading this from a confined bathroom on your parents’ community laptop, part of an evangelical group, I apologize. I’m not equipped to be your guide to contemporary science. For everyone else, it’s clear that the majority of life forms on our planet have evolved into their current states through extensive adaptation, developing features such as opposable thumbs, gills, or even poison-filled sacs.  You might be curious if there exists a creature that got it right on the first attempt—a flawless example that possessed all it required from the instant it came into being. Which organism on our planet has undergone the least transformation throughout the ages? Well, I have the answer for you, but it’s probably not as exciting as you were hoping for (I’ll also note that I’m not including microorganisms because the answer being “bacteria,” well, that’s no fun at all).  If I had to place my bets, I’d put my money on the horseshoe crab. It seems like these strange little creatures are destined to be the first to make contact with extraterrestrial beings. Alternatively, one might wish for a formidable apex predator, one that has never faced defeat and comes armed with natural spines and sharp edges from the very beginning.  The response is not related to either of those options. It's somewhat expected, in a peculiar way, that the apparent victor is simply a soggy collection of cells: the sponge. View pictures in App save up to 80% data. Shutterstock Not only have they been well-equipped to handle pretty much the entirety of life on Earth, sponges are also the oldest animal on earth, the first to emerge from life's single common ancestor: a phylum.

Of course they've branched off, and there’s many more species than there used to be, but that number still tops out at about 5,000.  In other words, SpongeBob SquarePants might trace his lineage all the way back to the very first multi-cellular organisms on Earth.

China's 'Batwoman' researcher continues to carry out hazardous coronavirus experiments despite concerns over lab leaks.

2025-04-04 20:21:59

Chinese researcher Shi Zhengli, aged 60, remains actively engaged in studying bat coronaviruses in Wuhan. Leading virologists warn that her research could have a 'potentially catastrophic' effect as we approach five years since the onset of the Covid-19 pandemic. View pictures in App save up to 80% data. Chinese virologist Shi Zhengli has allegedly earned the nickname 'batwoman' (file). A Chinese scientist is still conducting "potentially catastrophic" research into coronaviruses five years on from the start of the Covid pandemic which claimed millions of lives worldwide, according to experts. Shi Zhengli, 60, is one of the world's leading scientists working on bat coronaviruses in Wuhan. She has reportedly earned herself the nickname "Batwoman" as a result. She was thrown into the spotlight in late 2019 when a new form of coronavirus emerged in the region, with some scientists questioning whether Covid-19 leaked from a lab. In December, a two-year congressional investigation into the pandemic concluded the "weight of the evidence" suggests a lab leak was responsible. US lawmakers said in the report: "More and more senior intelligence officials, politicians, science editors, and scientists increasingly have endorsed the hypothesis that Covid-19 emerged as the result of a laboratory or research related accident." View pictures in App save up to 80% data. Her ongoing research has been labeled as 'potentially disastrous' (file). Nevertheless, leading virologists assert that Zhengli's team is still engaged in potentially harmful coronavirus research in Wuhan. In a study released in Nature, she proudly highlighted her team's achievement in creating the first "tailored" coronavirus "receptors." This advancement could enable researchers to modify viruses, allowing them to infect various species, including humans. Robert Redfield, the director of America's CDC during the pandemic, told The Sun: "It's potentially dangerous research. You are taking a non-pathogenic virus and changing it so that it could end up being dangerous to humans. You may have a pathogen that is restricted to pigs - but now you could totally change it so that it's highly infectious to other species too. View pictures in App save up to 80% data. An expert notes that Zhengli is 'experimenting with bat viruses and altering their receptors' (file). "She is experimenting with bat viruses and altering their receptors, which could enable them to infect animals like cows or chickens. This is a risky move with potentially disastrous outcomes. It might lead to a new pandemic affecting either animals or humans." Dr. Alina Chan, an expert in genetic engineering, stated that it seems Zhengli's team has now succeeded in "isolating" additional novel coronaviruses. She expressed concerns that this research is "risky" and prompts inquiries about the intentions of Zhengli's team regarding the handling of these new viruses once they cultivate them in the laboratory.

A newly discovered supergiant sea creature known as 'Darth Vader' has been found in the South China Sea, and it's truly enormous.

2025-03-31 01:37:53

The giant isopod has been given the name Bathynomus vaderi because of its similarity to the distinctive helmet of Darth Vader from the "Star Wars" franchise. View pictures in App save up to 80% data. Bathynomus vaderi was identified when researchers observed distinct variations that set it apart from other giant isopod species. Researchers have identified a previously unknown species of giant sea bug following an examination of samples acquired from fishermen in Vietnam. Bathynomus vaderi belongs to the genus Bathynomus — giant isopods that are abundant in cold, deep waters. It is a "supergiant," weighing over 2.2 pounds (1 kilogram) and growing up to 12.8 inches (32.5 centimeters) long, making it one of the largest known isopods. The species is named "vaderi" because its head resembles Darth Vader's iconic helmet from "Star Wars." B. vaderi has so far only been found near the Spratly Islands, an archipelago in the South China Sea, but it may also live in other parts of the South China Sea, according to the study. For the new study, published Jan. 15 in the journal ZooKeys, the team examined samples caught by local fishers and found that a few specimens had distinctive physical features that marked them as a newfound species. The team described B. vaderi’s pronounced depression in its hip bone and a unique bony ridge protruding from its coracoid bone that distinguishes it from other supergiant isopods. View pictures in App save up to 80% data. In October 2024, Dr. Nguyen Thanh Son showcased a massive specimen of a different giant isopod species, B. jamesi, which was discovered in a seafood market in Hanoi. This impressive creature weighed in at 2.62 kg. The researchers noted that Bathynomus species have recently become a delicacy in Vietnam, often compared to lobster. The local demand has turned these sea bugs into an expensive staple of the live-seafood market, leading to increased fishing pressures in the region. According to the researchers, the commercial aspect presents both benefits and obstacles. While the booming market may pose risks to giant isopods, it also has the potential to lead to more stringent regulations and promote sustainable methods in deep-sea fishing. B. vaderi is not the largest isopod species. That title goes to B. jamesi, which can grow to around 20 inches (50 cm) and weigh 5.7 pounds (2.6 kg). Supergiant isopods are often found in deep-sea environments so they are challenging to study due to their inaccessibility.

Novel organic solar cells demonstrate exceptional durability in tests against space radiation.

2025-04-07 05:39:11

Traditionally, silicon and gallium arsenide have been the primary materials used in solar cells, but now a new player is making its way into the spotlight: organic solar cells. View pictures in App save up to 80% data. In order to explore the vastness of space, both space agencies and private companies must first overcome the challenge of securing reliable energy sources. Silicon and gallium arsenide have long been the primary materials used in solar cells, but a new player is making waves: organic solar cells. Constructed from carbon-based substances, these cells present numerous benefits: they are lightweight, adaptable, and could be more cost-effective to manufacture. However, their resilience in the extreme conditions of space has raised significant concerns. A new study conducted by researchers at the University of Michigan examined how proton radiation, a significant hazard in outer space, affects organic solar cells. Earlier studies on organic solar cells in space mainly focused on assessing their overall efficiency following radiation exposure. In contrast, the latest research takes a more in-depth approach by exploring the molecular mechanisms responsible for the decline in performance. "According to Yongxi Li, the lead author of the research, 'Silicon semiconductors face stability issues in space due to proton irradiation from the sun.'" "Li noted, 'We conducted tests on organic photovoltaics using protons, as these particles are regarded as the most harmful to electronic materials in space.'" Adaptable organic cells Gallium arsenide is favored for space missions because of its impressive efficiency in converting sunlight into electricity. This material effectively harnesses a large fraction of solar energy. Additionally, it is resilient against the harmful impacts of protons, which are plentiful in the space environment. Nevertheless, there are some drawbacks associated with it. For example, gallium arsenide is costly to manufacture. Additionally, similar to silicon, it has a considerable weight and is challenging to manipulate, which may restrict its use in space exploration missions.  On the other hand, organic solar cells are recognized for their lightweight and flexible characteristics. These qualities make them appealing for use in space applications, where minimizing weight and the capacity to adapt to curved surfaces are crucial. The objective of this study is to evaluate the durability of organic solar cells when exposed to the extreme conditions of outer space, in order to establish their viability for upcoming space exploration missions. Electron confinement Interestingly, the study found that organic solar cells made with small molecules were highly resistant to proton radiation. The cells displayed no damage after three years of radiation exposure.  Nonetheless, the ones constructed with more intricate polymer frameworks saw a notable drop in efficiency, with nearly 50% of their initial performance diminished. The scientists found that proton radiation has the ability to disrupt chemical bonds in the polymer, leading to the formation of "electron traps" that impede electrical conductivity. "According to Stephen Forrest, the Peter A. Franken Distinguished University Professor of Engineering at the University of Michigan, 'Our research indicates that protons can break down certain side chains, resulting in an electron trap that negatively impacts the efficiency of solar cells.'" The team found that these “traps” can be healed by gently heating the cells. This suggests the possibility of self-healing solar cells that could operate effectively in space. "Forrest mentioned, 'This issue can be resolved through thermal annealing, which involves heating the solar cell. However, we may also discover methods to fill the traps with different atoms, thereby eradicating the problem altogether.'" Research indicates that organic solar cells oriented towards the sun may have the ability to self-repair when exposed to elevated temperatures, approximately 100°C (212°F), a phenomenon that has been documented in controlled laboratory experiments. “But questions remain: for instance, will that repair still take place in the vacuum of space? Is the healing reliable enough for long missions?” the researchers stated in the press release.  On the other hand, scientists are investigating the potential for creating materials that naturally prevent the development of electron traps that can degrade performance. The findings were published in the journal Joule.

Earth is easily identified at the bottom of the picture, as are the many stars that dot the rest of the image. Look more closely, however, and you’ll see a number of streaks in the blackness, which Pettit identifies as SpaceX Starlink satellites that provide internet connectivity to folks back on terra firma. The Milky Way is prominently displayed across the center of the image, and the zodiacal light referenced by Pettit manifests as a subtle, diffuse glow resembling a triangular or cone-like shape. This otherworldly phenomenon occurs when sunlight scatters off dust particles floating in the space between planets within our solar system. OH emission, commonly referred to as hydroxyl airglow, is a natural occurrence found in the upper atmosphere of Earth, particularly within the mesosphere and lower thermosphere. This phenomenon is marked by the emission of infrared radiation from energized hydroxyl (OH) molecules, creating a distinctive brownish hue that can be observed encircling the Earth, as depicted in Pettit’s photograph. As the ISS orbits the Earth, astronauts witness 16 sunrises and sunsets daily, offering them a constantly shifting view from their unique vantage point in space. Across his four space missions over the last 30 years, Pettit has earned a deserved reputation for his outstanding photography work, capturing sublime images of Earth and beyond. The advent of social media has allowed him to share his work with a growing audience of fans who never quite know what he’s going to post next. Surprises from his current mission, which began in September and runs through March, have included a remarkable shot of a Crew Dragon spacecraft returning to Earth at high speed at the end of a mission. He also managed to capture a Starship launch from SpaceX’s Starbase site in Texas when the ISS, through sheer luck, passed overhead during liftoff.

The 320-foot-high rocket will not be launching any satellites throughout the mission. View pictures in App save up to 80% data. Blue Origin's New Glenn rocket is now scheduled for launch on Monday at 1 a.m. ET from Cape Canaveral Space Force Station in Florida. The first launch of the New Glenn has been postponed by 24 hours because of unfavorable weather conditions in the Atlantic Ocean, which was the intended landing area for the New Glenn booster. "Due to ongoing adverse sea state conditions for the booster landing, we are postponing our NG-1 launch by one day, now scheduled for no sooner than January 13. The three-hour launch window remains unchanged, starting Monday at 1 a.m. EST (0600 UTC)," Blue Origin announced on X. Reusable initial phase Earlier, the launch was scheduled for January 10 and then January 12. The New Glenn rocket, which was being developed for almost a decade, has a reusable first stage like SpaceX’s Falcon 9 and Falcon Heavy rockets.The 320-foot-high rocket will not be launching any satellites throughout the mission. However, it’s carrying a payload, which is a test version of Blue Origin’s new “Blue Ring” spacecraft platform. The company will make efforts to recover the rocket’s first stage on Monday morning as the booster lands in the Atlantic Ocean on its Landing Platform Vessel 1. Called Jacklyn, the barge is nicknamed after the mother of Jeff Bezos, who is the founder of Blue Origin. Capturing the booster. The payload for this mission is the Blue Ring Pathfinder. This spacecraft will test Blue Ring’s core flight, ground systems, and operational capabilities as part of the Defense Innovation Unit’s (DIU) Orbital Logistics prototype effort.   “Our key objective is to reach orbit safely. We know landing the booster on our first try offshore in the Atlantic is ambitious—but we’re going for it,” said the company in a statement. Jarrett Jones, Senior Vice President of New Glenn, emphasized that this marks the inaugural flight of New Glenn, and the team has engaged in extensive preparations leading up to this moment. The procedure “However, no level of ground testing or mission rehearsals can truly substitute for the experience of flying this rocket. The moment has come to take to the skies. Regardless of the outcome, we will gain insights, improve, and utilize that knowledge for our upcoming launch,” Jones stated. “This marks our inaugural flight, and we have put in extensive preparation,” stated Jarrett Jones, Senior Vice President of New Glenn. “However, nothing can substitute for the experience of actually flying this rocket, despite all the ground tests and mission simulations we’ve conducted. The moment has come to take to the skies. Regardless of the outcome, we will gain insights, make improvements, and use that information for our upcoming launch.” During the launch, after burning through most of its fuel, the booster will detach from the upper portion of the rocket, which includes the vehicle’s nose cone, or payload fairing, that’s designed to shield cargo during liftoff. The booster will then use fins and strakes — or winglike attachments that flare out from its top and base, respectively — to help guide itself toward its landing target, a seafaring recovery platform, reported CNN. Ignition test In late December 2024, New Glenn achieved a significant milestone by successfully conducting an integrated launch vehicle hotfire test, marking the last major step before its inaugural flight. The NG-1 mission is set to transport a Blue Ring Pathfinder as its initial payload. The seven-engine hotfire lasted 24 seconds and marked the first time Blue Origin operated the entire flight vehicle as an integrated system. The multi-day test campaign leading up to the hotfire included numerous inert functional and tanking tests. The integrated launch vehicle included the first and second stages of the NG-1 flight vehicle, and a payload test article comprised of manufacturing test demonstrator fairings, a high-capacity fixed adapter flight unit, and a 45,000 lb payload mass simulator.  According to Blue Origin, the official NG-1 Wet Dress Rehearsal showcased the ultimate launch protocols that precede the hotfire engine test. “All seven engines performed nominally including at 100% thrust for 13 seconds. The test also demonstrated New Glenn’s autogenous pressurization system, which self-generates gases to pressurize GS1’s propellant tanks,” said the company in a statement. Reports revealed that New Glenn’s two engines, optimized to function in the vacuum of space, should fire up and propel the vehicle to speeds necessary to enter orbit — typically around 17,500 miles per hour, or nearly 23 times the speed of sound.

View pictures in App save up to 80% data. Meteor shower Home video and audio of a meteorite crashing into the sidewalk outside a Canadian man’s home is believed to be the only recording of its kind. “As far as I know, and I’ve asked around, it’s probably the first time that the sound of an impact of a meteorite hitting something at the surface has even been recorded,” University of Alberta meteorite expert Chris Herd told the Canadian Broadcasting Corporation (CBC). Prince Edward Island homeowner Joe Velaidum noticed white debris on his lawn and sidewalk after walking his dog last July. When he checked the footage from his doorbell camera, he noticed a fast-moving object fall from the sky, accompanied by a sound that resembled ice breaking. Velaidum collected approximately seven grams of the debris and handed it over to scientists, who determined that his land had indeed been struck by a meteorite. Herd met up with Velaidum a few days later and the pair recovered nearly 100 more grams of debris. Though researchers confirmed the samples to be from an ordinary chondrite meteorite, the most common space rock that strikes Earth, it’s the only meteorite known to have landed on Prince Edward Island, which sits roughly 400 miles northeast of Maine. Herd mentioned that he observed signs indicating that the meteorite might have sustained damage while it was colliding within an asteroid belt. By the time it impacted the Earth, traveling at speeds exceeding 120 mph, the already compromised object likely broke apart, resulting in the sound captured in the remarkable recording. This week, Valaidum shared with the CBC that he had been standing in the exact spot where the object struck just moments before. He can't shake the thought of what might have occurred if he had remained there a little longer. "It likely would have torn me apart," Velaidum stated to the publication.

AI video generators have made significant strides in their brief history, and an unexpected benchmark that many of us use to gauge this advancement has—due to various reasons—manifested as videos of Will Smith enjoying spaghetti. As one user pointed out on flight simulation forum AVSIM in late September 2024, these videos have become an AI benchmark. The difference in quality between the original AI-generated Will Smith eating spaghetti video—which went viral after it was posted to the r/stablediffusion subreddit by u/chaindrop in March 2023—and subsequent iterations—is stark.

Additionally, the abundance of noodles adds another layer of complexity for the AI to manage. But culturally speaking, as with any meme, the why doesn’t so much matter. It is as much a method of communication as it is an inside joke. Much like the Utah Teapot of the late ’70s and ’80s—a famous 3D model and computer graphics benchmark that was kind of a pre-meme meme—Will Smith eating spaghetti videos have become a cultural reference that breaches the gap between tech and pop culture. It has become an AI litmus test for the layman, a way for the culture at large to participate and track developments in the latest big tech wave. 2023 AI Will Smith eating spaghetti was comically gruesome. 2024 AI Will Smith eating spaghetti is plausible. 2025 AI Will Smith eating spaghetti might not be recognizable as AI at all (the actor’s real-life parody of the spaghetti-eating videos is undoubtedly hastening this certainty, providing generators with more exact data to replicate).

Chimpanzees Exhibit Genetic Adaptations for Their Local Environments and Resistance to Malaria

2025-03-10 02:40:53

View pictures in App save up to 80% data. Chimpanzees, our nearest evolutionary kin, exhibit a remarkable ability to genetically adapt to their specific environmental circumstances. A groundbreaking study spearheaded by a group of international researchers from University College London (UCL) has uncovered vital information regarding how these extraordinary primates have developed to thrive in diverse habitats throughout Africa. By examining the genetic changes that support their survival, this research indicates that these adaptations not only shed light on the evolutionary path of chimpanzees but also provide important insights into the effects of malaria on human populations. Notably, chimpanzees possess more than 98% of their DNA in common with humans, establishing them as vital subjects for research in evolutionary biology and disease resistance. The results of this extensive study, recently published in the prestigious journal Science, pave the way for new insights into how genetic diversity can provide benefits in the face of environmental changes and disease challenges, especially malaria, which continues to pose significant risks for both wild chimpanzees and humans alike. Chimpanzee populations from various regions in Africa exhibit unique genetic adaptations that correspond to their specific environments, underscoring their ability to thrive amidst ecological diversity. Unlike many other primates that primarily reside in forested areas, chimpanzees have shown remarkable flexibility by inhabiting a range of ecosystems, from open woodlands to savannahs. This evolutionary adaptability is vital, particularly given that chimpanzees are classified as endangered due to threats such as habitat destruction, poaching, and the transmission of diseases linked to human activities. Professor Aida Andrés, the primary author of the study from the UCL Genetics Institute, highlights the importance of comprehending these genetic adaptations for the survival of chimpanzee populations and their resilience against environmental shifts. The research team analyzed the genetic data of 828 wild chimpanzees from 30 diverse populations, employing advanced genomic methods to explore how genetic variations correspond to the unique challenges encountered by each group in their specific environments. The research utilized a methodology that focused on collecting and analyzing fecal samples through the Pan African Programme: The Cultured Chimpanzee (PanAf). This cutting-edge strategy enabled the team to obtain genetic information while minimizing interference with the elusive wild chimpanzee populations, thus safeguarding their natural behaviors and habitats. By employing sophisticated laboratory techniques, the study successfully identified exonic variants associated with pathogen resistance, providing insights into the evolution of these genetic traits in relation to local environmental challenges. In their research, scientists discovered compelling evidence of genetic adaptation linked to various pathogens, particularly emphasizing malaria. The findings indicated that specific genetic variants were more common in chimpanzees living in areas abundant with pathogens, suggesting that malaria poses a significant health risk to these groups. Notably, the genes GYPA and HBB, which are associated with malaria resistance in humans, were identified as key elements in the adaptation of chimpanzees. These findings emphasize the evolutionary similarities shared by chimpanzees and humans, while also suggesting significant consequences for human health. The genetic closeness raises crucial questions regarding the transmission of diseases across species, such as malaria and HIV, and underscores the necessity of researching wild chimpanzee groups to create effective prevention methods or treatments for these diseases that threaten human health. Additionally, the study indicates that chimpanzees inhabiting savannah regions have developed specific adaptations to address the unique difficulties posed by lower rainfall, elevated temperatures, and scarce food supplies. Their capacity to endure and flourish in these varied settings offers an intriguing insight into how our human forebears may have faced comparable obstacles millions of years ago during their shift from wooded areas to open savannah landscapes. An important facet of the research pertains to the wider consequences for conservation initiatives focused on safeguarding the genetic diversity of chimpanzee groups. With the acceleration of environmental shifts driven by climate change and human activities, it is increasingly essential to safeguard the genetic variations in these vulnerable populations to enhance their resilience. Preserving genetic resources is critical for the enduring survival of chimpanzees, as a healthy gene pool can support their ability to adapt to evolving ecological circumstances. This research exemplifies the worldwide dedication to exploring primate conservation and genetic adaptation through collaboration. Contributions from various institutions in Africa, Europe, and North America emphasize the importance of interdisciplinary teamwork in tackling intricate biological issues. The researchers urge both the scientific community and the general public to interact with their findings and back conservation efforts designed to protect the future of chimpanzees and their ecosystems. The public can engage in this research through community science initiatives such as ChimpandSee.org, where volunteers are encouraged to help annotate videos featuring chimpanzees. These collaborative projects not only enhance awareness of chimpanzees and the conservation issues they face, but also encourage community participation in scientific activities, ultimately aiding in the understanding and protection of these extraordinary animals. In conclusion, the results of this pioneering research shed light on the genetic adaptations of chimpanzees that enable them to flourish in various environments and tackle new challenges like malaria. This study underscores the complex relationships between different species and their surroundings, highlighting the urgent need to safeguard the genetic diversity crucial for the survival of both chimpanzees and humans in a rapidly evolving world.

Cuttlefish Are Capable of Passing the Marshmallow Test Designed for Children

2025-03-15 20:30:14

View pictures in App save up to 80% data. (Image credit: Steve De Neef/VW Pics/Universal Images Group, courtesy of Getty Images) Cuttlefish are smart. Like, human-level smart. While they’re not quite on par with an adult human with a college degree, studies show that the common cuttlefish can delay gratification, a trait found in creatures we commonly consider intelligent, like primates, corvids, some dog breeds, and humans. A 2021 study tested the cognitive abilities of cuttlefish with a modified version of the famous Stanford marshmallow experiment. The cuttlefish were divided into tanks with two types of food — a delectable live shrimp and a less delectable raw dead prawn. Content created by VICE A door marked with a circle swung open without delay, exposing the prawn inside. In contrast, the door adorned with a triangle would take anywhere from 10 to 130 seconds to open, ultimately disclosing the live shrimp. The final door, featuring a square, remained perpetually shut. The researchers discovered that cuttlefish exhibited a strong preference for live shrimp, often opting to forgo the immediate availability of dead prawns. They were willing to wait as long as necessary for the triangle door to open, allowing them to access the live shrimp instead. The cuttlefish recognized that the live shrimp was the tastier and more appealing option, so it decided to bide its time until its favorite treat was within reach. Different species exhibit the ability to postpone gratification for reasons that are often more intricate than those of the cuttlefish, such as the practice of saving food for future use. In its natural environment, the cuttlefish faces threats from predators while foraging, which might explain its more selective behavior, as it waits for the perfect opportunity to secure food. “Cuttlefish spend most of their time camouflaging, sitting and waiting, punctuated by brief periods of foraging,” lead author Alexandra Schnell said in a press release. "When they search for food, they lose their camouflage, making them vulnerable to any ocean predator looking to catch them. We hypothesize that the ability to delay gratification may have developed as a consequence of this behavior, allowing cuttlefish to enhance their foraging strategy by waiting for higher quality food options."

Gaze upon the beauty of the iris.  Absolutely, having an attractive eye color is great. However, recent studies indicate that the size of the pupil and the brightness of the iris are what truly captivate attention.  “Brighter irises and larger pupils elicited greater donations,” noted experts from the Netherlands’ Leiden University in a recent report on how our eyes influence others’ perceptions of us — as well as their willingness to fork over charitable funds.  View pictures in App save up to 80% data. Recent studies have revealed that the brightness of a person's irises and the size of their pupils play a significant role in determining their attractiveness to others. The research team carried out two experimental studies, asking participants to evaluate images of non-human primates — specifically, members of the monkey family — featuring modified eye appearances.  In the initial research, 64 individuals were presented with images of 32 distinct species, such as chimpanzees, bonobos, and pig-tailed macaques. The pupil sizes of these animals were altered to look either constricted or dilated, while their iris brightness remained unchanged.  "The researchers inquired about the amount of money participants would be willing to contribute for each portrait, while also asking them to evaluate the portraits based on their perceived cuteness, friendliness, and attractiveness," the investigators reported. They observed that donations “rose for portraits featuring dilated pupils, but only in species that possess bright irises.” View pictures in App save up to 80% data. Researchers manipulated images of various non-human primate species to investigate how individuals perceive them, focusing specifically on their eyes. Participants also found animals with larger pupils to be cuter, friendlier, and more appealing compared to those without this eye-catching feature.  In their second investigation, analysts adjusted the size of the pupil as well as the brightness of the iris.  The experts concluded, “Contributions were significantly higher when participants viewed portraits of primates with bright irises instead of dark ones. Additionally, donations increased when the pupils were illustrated as dilated rather than constricted.” View pictures in App save up to 80% data. The research team discovered that individuals showed a greater attraction to animals that had enlarged pupils and vibrant irises. Participants in the study assessed primates with more vibrant irises as more adorable when their pupils were dilated, while they found them less appealing when the pupils were constricted.  Participants noted that primates with brighter irises appeared friendlier when their pupils were dilated, while those with constricted pupils were seen as less friendly. Additionally, respondents considered primates with brighter irises to be more attractive, but this perception only applied when the pupils were dilated. The findings align with earlier research conducted by Zachary Estes at the University of London. In a study published in July, Estes demonstrated that “individuals tend to be perceived as more attractive when their irises are larger, which contributes to a brighter appearance in their eyes.” View pictures in App save up to 80% data.

The James Webb Space Telescope has reached a significant milestone by discovering 44 ancient stars.

2025-03-10 23:40:33

View pictures in App save up to 80% data. fabio lamanna - stock.adobe.com - for illustrative purposes only Thanks to NASA's James Webb Space Telescope (JWST), a team of astronomers from the University of Arizona’s Steward Observatory has reached a significant breakthrough in cosmic research. Through the observation of a galaxy located approximately 6.5 billion light-years away, which dates back to a time when the universe was only half as old as it is now, researchers discovered 44 distinct stars. This achievement was enabled by gravitational lensing and the light-gathering capabilities of the JWST. As a result, this discovery has established a new record for the highest number of individual stars observed in a distant galaxy. “This groundbreaking discovery demonstrates, for the first time, that studying large numbers of stars in a distant galaxy is possible,” explained Fengwu Sun, a postdoctoral researcher at the Center for Astrophysics | Harvard & Smithsonian (CfA) and co-author of the study. Sun elaborated on how previous studies conducted with the Hubble Space Telescope managed to identify around seven stars. Nevertheless, thanks to the enhanced capabilities of the JWST, researchers are now able to observe stars that were once too distant to detect. This progress is important as it enables researchers to examine dark matter in the lensing areas of galaxies and stars by observing a greater number of individual stars, a feat that was unattainable when only a limited number of stars could be seen. A group of stars was identified through the analysis of JWST images of a galaxy referred to as the Dragon Arc. This galaxy is situated behind a large galaxy cluster called Abell 370, and the gravitational lensing caused by Abell 370 alters the Dragon Arc's spiral structure, giving it a stretched and elongated appearance. Through the examination of the star colors within the Dragon Arc, the research team found that a significant number of these stars are red supergiants. This contrasts sharply with earlier studies that predominantly recognized blue supergiants. The researchers highlighted that this difference emphasizes the JWST's ability to utilize infrared wavelengths, enabling it to detect cooler stars that may have been overlooked by other telescopes. View pictures in App save up to 80% data. Fabio Lamanna – stock.adobe.com – for illustrative purposes only. Sun stated, "Our initial goal was to find a background galaxy that is being lensing-magnified by the galaxies within this enormous cluster, but in the process, we ended up discovering these individual stars." "However, as we analyzed the data, we discovered what seemed to be numerous individual star points. This was an exhilarating discovery, as it marked the first occasion we could observe such a vast number of distant individual stars." Galaxies such as the Milky Way generally contain tens of billions of stars, allowing astronomers to examine individual stars in nearby galaxies. However, the light emitted by stars in galaxies located billions of light-years away tends to merge during its extensive journey to our planet. This phenomenon is exactly what has made it challenging for scientists to comprehend the processes behind the formation and evolution of galaxies. Yoshinobu Fudamoto, the primary author of the study, explained that while distant galaxies often appear as “diffuse, fuzzy blobs,” these seemingly indistinct formations actually consist of numerous individual stars that current telescopes are unable to resolve. Recent developments in astronomy have unveiled exciting opportunities thanks to gravitational lensing, a phenomenon in which the intense gravitational force of large celestial bodies enhances the light from distant stars. This effect enables the light from these remote stars to be magnified, making them observable with advanced telescopes. By conducting further observations with the JWST, researchers aim to discover an even greater number of magnified stars within the Dragon Arc, potentially allowing for the study of hundreds of far-off stars. Examining these specific stars could enhance our comprehension of the architecture of gravitational lenses and aid in deciphering the enigmas related to dark matter.

A spacecraft has flown past Mercury's north pole, capturing and transmitting breathtaking images.

2025-03-10 13:13:04

Kindly sign in to proceed. Looking to create an account? View pictures in App save up to 80% data. CAPE CANAVERAL, Fla. (AP) — A spacecraft has beamed back some of the best close-up photos yet of Mercury’s north pole. The European and Japanese robotic explorer swooped as close as 183 miles (295 kilometers) above Mercury's night side before passing directly over the planet's north pole. The European Space Agency released the stunning snapshots Thursday, showing the permanently shadowed craters at the top of of our solar system’s smallest, innermost planet. Cameras also recorded images of adjacent volcanic plains and the largest impact crater on Mercury, measuring over 930 miles (1,500 kilometers) across. This was the sixth and final flyby of Mercury for the BepiColombo spacecraft since its launch in 2018. The maneuver put the spacecraft on course to enter orbit around Mercury late next year. The spacecraft holds two orbiters, one for Europe and the other for Japan, that will circle the planet's poles. The spacecraft is named in honor of the late Giuseppe (Bepi) Colombo, an Italian mathematician from the 20th century. He played a significant role in NASA's Mariner 10 mission to Mercury during the 1970s and, twenty years later, was involved in the Italian Space Agency's tethered satellite project that was launched aboard U.S. space shuttles. ___ The Associated Press Health and Science Department is supported by the Science and Educational Media Group of the Howard Hughes Medical Institute and the Robert Wood Johnson Foundation.

A glimpse of the metal ring, approximately 8 feet in diameter, that descended from the sky into Mukuku village on December 30 in the eastern region of Makueni County, Kenya. Over a week has passed since initial reports surfaced regarding a "luminescent metal ring" that descended from the sky and landed close to a secluded village in Kenya. According to the Kenya Space Agency, the object weighed 1,100 pounds (500 kg) and had a diameter of more than 8 feet (2.4 meters) when measured after it landed on December 30. A couple of days later, the space agency confidently reported that the object was a piece of space debris, saying it was a ring that separated from a rocket. "Such objects are usually designed to burn up as they re-enter the Earth’s atmosphere or to fall over unoccupied areas, such as the oceans," the space agency told The New York Times. Following the release of the initial reports in Western media, a group of committed space enthusiasts has been leveraging open source information to pinpoint the exact space object that landed in Kenya. As of now, they have yet to determine the specific rocket launch associated with the large ring. Currently, certain space observers suspect that the object might not have originated from outer space at all. Did it actually originate from outer space? The space environment is becoming more congested; however, significant pieces of metal from rockets are typically not drifting unnoticed and unmonitored in Earth's orbit. "It was suggested that the ring is space debris, but the evidence is marginal," wrote Jonathan McDowell, an astrophysicist working at the Harvard-Smithsonian Center for Astrophysics. McDowell is highly regarded for his analysis of space objects. "The most likely space-related possibility is the reentry of the SYLDA adapter from the Ariane V184 flight, object 33155. Nevertheless, I am not fully convinced that the ring is space debris at all," he wrote. Another prominent space tracker, Marco Langbroek, believes it's plausible that the ring came from space, so he investigated further into objects that may have returned around the time of the object's discovery in Kenya. In a blog post written Wednesday he noted that apart from the metal ring, other fragments looking consistent with space debris—including material that looks like carbon wrap and isolation foil—were found several kilometers away from the ring.

Novel Method Integrates Theoretical Principles with Experimental Investigations of Proton Structure

2025-03-30 08:23:31

An artist's illustration of the inside of a proton. In the realm of quantum chromodynamics, the fundamental quarks are categorized into three distinct "colors," while they also possess up and down "flavors." The image additionally features virtual pairs of quarks and antiquarks, as well as the gluons responsible for holding the quarks tightly together. The Field of Science Newswise — Protons and other subatomic particles that are subject to the strong nuclear force have a complex structure that involves even more fundamental constituents called quarks and gluons. These quarks and gluons bind under the influence of quantum chromodynamics (QCD). QCD is the theory of strong interaction of quarks and the role of color symmetry. However, the mechanisms that lead to quarks and gluons combining to form the particles we see in nature are very mysterious and poorly understood. For example, virtual quarks and gluons constantly appear and disappear within our current picture of the dynamics in the proton. So, which quarks and gluons are actually “in” a proton is a difficult question to answer.  A major part of QCD research is driven by the goal of solving open fundamental questions at the heart of how QCD operates and how quantum mechanical theories can be merged with the theory of relativity. Recent progress in theoretical QCD has opened the way to connecting questions about the structure of particles like the proton with high-energy particle collision measurements. The Effect As theorists generate new ideas about QCD, other researchers plan experiments to test those ideas. These tests involve colliding particles like electrons and protons at high energies and then examining the results. By extrapolating backwards in time, physicists will use the remnants of the collisions to infer information about the structure of the original particles. However, the same theoretical difficulties that motivated these studies have left a key question unresolved. Namely, how do scientists relate the physics of the specific collisions with the physics of the internal structure of the particles themselves? The recent work provides the toolbox needed to resolve this question while also accounting for the theoretical subtleties. Overview Much of the experimental work related to extracting the quark and gluon structure of protons occurs at existing particle accelerators like the Thomas Jefferson National Accelerator Facility and the Relativistic Heavy Ion Collider, and in the future at the Electron Ion Collider. A large part of current research into the structure of the proton, both theoretical and experimental, involves identifying, extracting, and analyzing the bound state distributions of quarks and gluons in the proton, mapping out their motion, and understanding how this relates to the overall observed properties of the proton like its spin and mass. In the past, researchers found inconsistencies in the way physicists combined fundamental QCD theory to the study of data. The new theoretical results provide a clear recipe and boost confidence that data taken in future experiments can be reliably interpreted. Financial Support This research received funding from the Department of Energy (DOE) Office of Science, specifically the Office of Nuclear Physics. Additional support came from the DOE contract that enables Jefferson Science Associates, LLC to manage the Thomas Jefferson National Accelerator Facility. Furthermore, funding was provided by the European Union's Horizon 2020 program for research and innovation.

All You Need to Know About January's Full Wolf Moon and the Occultation of Mars

2025-03-26 05:23:57

The initial Full Moon of 2025 will rise higher and last longer than usual, and it will briefly obscure Mars. View pictures in App save up to 80% data. In the Northern Hemisphere, we’re in the dead of winter and most people are spending their evenings inside where it’s warm. You might want to bundle up and head outside soon, though, to get a look at January’s Wolf Moon and the occultation of Mars. The full Moon happens roughly once every month (sometimes it happens twice in a month, something known as a Blue Moon), and each has its own name. In the United States the January full Moon is known as the Wolf Moon. It’s said that the name comes from the wolves which historically howled at night during this time of year. In other places and among other cultures, it has other names including the Ice Moon, Old Moon, Center Moon, Cold Moon, and many more. In fiction, the full Moon is a time for weirdness and wonder, a time when werewolves emerge to hunt their prey. Later this month, a reimagined Wolf Man will stalk into theaters from director Leigh Whannell (The Invisible Man). After moving from San Francisco to Oregon, Blake (Christopher Abbott) and his family are attacked by a werewolf. They escape with their lives and board themselves inside the house, but Blake was scratched and he’s beginning to change. Wolf Man hits theaters January 17, but in the meantime, we have a real-world Wolf Moon of our own to check out. When a full Moon occurs, the Moon is positioned directly opposite the Sun in relation to the Earth, resulting in its entire surface being illuminated as seen from our perspective. This alignment is why lunar eclipses can only take place during a full Moon, as it is the only time the Earth can interpose itself between the Moon and the Sun. At other times, the Moon receives light from different angles in relation to the Earth, which creates its distinctive phases, ranging from full Moon to new Moon and all the variations in between.

The Moon is set to reach its full phase on the evening of Monday, January 13, at 5:27 PM ET. However, it will look full for approximately three days, starting from Sunday evening and lasting through Wednesday morning. This January's Wolf Moon will also be the highest Full Moon of the year in the Northern Hemisphere. This phenomenon occurs because the Sun and the Moon are positioned nearly on the same plane in space. Due to the tilt of the Earth, the Sun is at its lowest point while the Moon is at its peak during the Winter Solstice, which recently occurred on December 21, 2024. This full Moon will take a longer route across the sky, making it visible for an extended period. Expect to see the Moon rise in the east roughly when the Sun is setting in the west. Similarly, it will set in the west just as the Sun is rising the following morning. The January Full Moon offers a splendid opportunity to observe Mars and various other celestial phenomena. View pictures in App save up to 80% data. A depiction of the planet Mars. Everything in space is in motion. From our point of view, the Moon’s motion is the result of moving along its orbital path and the rotation of the Earth. At the same time, the background planets of our solar system are also in motion, and sometimes they cross paths. On the evening of January 13, the Moon will pass in front of Mars. When the Moon passes in front of another object from our point of view, it’s called an occultation. It’s less impressive than the mid-day darkness and coronal views of a solar eclipse but it’s still a neat way to spend an evening outside. The Moon will cover Mars for about an hour and 15 minutes that evening. The precise timing of the occultation will vary depending on your position on the globe. You can use tools like Stellarium Web to figure out the best viewing times for your location. When you're outdoors, take a second to admire the entire sky. Even though Mars may briefly vanish from view, Venus and Saturn will grace the western sky during the early evening hours. Jupiter will be prominent for much of the night, and you can observe all of these planets in finer detail with a small telescope or a pair of binoculars.

The Earth's Mantle is Much More Active and Unpredictable Than We Previously Believed

2025-04-02 02:35:24

The Earth's mantle is more than merely a hot and dense rock layer; it serves as a vibrant and complex engine that propels the geological processes of our planet. A lot of individuals picture the Earth as having a neat and organized structure comprised of distinct layers: a thin crust on the outside, a thick mantle beneath it, and a core at the center. However, what exists beneath the surface is a far more intricate and active environment than this oversimplified depiction suggests. Recent studies employing advanced Full-Waveform Inversion (FWI) technology have uncovered that the Earth’s mantle — an enormous layer extending nearly 2,900 kilometers deep — is a tumultuous and diverse amalgam of structures, calling into question long-held beliefs regarding its makeup and dynamics. View pictures in App save up to 80% data. Positive and negative anomalies found within the mantle. Image source: Nature. The Earth’s mantle, a massive layer of rock beneath the crust, is the “engine” of plate tectonics. Stretching nearly 2,900 kilometers deep, it shapes much of the planet’s geology and evolution. But the problem is we can’t really see the mantle or dig to it. Instead, much of what we know about the mantle (and the deeper areas) comes from seismology. Seismology studies the Earth’s interior by analyzing how seismic waves, generated by earthquakes or artificial sources, travel through its layers. When these waves encounter changes in material properties — such as differences in temperature, density, or composition — they change speed, direction, or type. By measuring these changes at seismic stations on the surface, scientists can map anomalies in the mantle, like faster wave speeds indicating colder, denser materials, or slower speeds suggesting hotter or less dense areas. Seismic tomography, an important technique, uses these measurements to create 3D models of the mantle. This reveals its hidden structures and helps us to understand its dynamic processes. But seismic tomography has its own limitations. A recent study employing Full-Waveform Inversion (FWI) has redefined what we know about the mantle, revealing intricate structures previously undetectable by conventional methods. An undiscovered realm hidden beneath the Earth's surface Plate tectonics is the theory that underlies modern geology. It basically states that Earth’s outer shell, or lithosphere, is divided into large, rigid plates that float and move on the semi-fluid layer beneath, called the asthenosphere. These plates interact at their boundaries in three main ways: they converge, causing subduction or mountain formation; they diverge, creating new crust at mid-ocean ridges; or they slide past each other along transform faults. When two tectonic plates come together, the denser plate is forced down beneath the lighter one, leading to subduction. This denser plate then descends into the mantle below. View pictures in App save up to 80% data. Illustration of subduction. Image sourced from Wiki Commons. Traditionally, positive seismic wave speed anomalies in the mantle were attributed to “cold slabs” — remnants of subducted tectonic plates. Essentially, seismic wave speed anomalies in the mantle have long been considered the “footprints” of such plates. But the new study found that many of these anomalies do not spatially correlate with known subduction zones. In fact, it found that just 60–70% of subduction zones align with positive anomalies. “According to Thomas Schouten, the lead author and a PhD candidate at the Geological Institute of ETH Zurich, it seems that these zones in the Earth’s mantle are far more common than we had earlier believed.” It’s unlikely that we’ve missed any big subduction zones, so instead, this suggests that the wave speed anomalies could have a different cause. The researchers suggest that these anomalies could also be caused by compositional differences, not just temperature variations. For example, anomalies might stem from the presence of chemically distinct materials like basalt-rich rocks or delaminated lithosphere. For example, areas abundant in basalt, which are remnants of old oceanic crust, demonstrate increased wave velocities because of the development of dense minerals such as garnet and bridgmanite under high-pressure conditions.

The advanced capabilities of Full Waveform Inversion (FWI) arise from its proficiency in simulating complete seismic wavefields, which encompass reflected, refracted, and scattered waves, rather than merely focusing on travel times. This method greatly improves resolution, especially in areas where seismic station coverage is sparse. In contrast to conventional models, FWI is adept at detecting fine variations and smaller-scale geological features. One of the challenges associated with FWI is its significant computational requirements, which necessitate the use of sophisticated algorithms and GPU-accelerated simulations to process the data effectively. However, recent developments have yielded impressive outcomes: anomalies that previous models either missed or misrepresented are now distinctly observable. The REVEAL model, developed through FWI, represents the most comprehensive depiction of the Earth's mantle achieved so far. The implications are substantial. Past models of tectonic history often relied on the correlation between mantle anomalies and subduction zones. With these processes affecting everything from volcanoes and earthquakes to mountain formation, figuring out what exactly is causing these anomalies would substantially improve our understanding of the Earth. However, at this moment, we remain unaware of it.  "That's the challenge we're facing. The new high-resolution model allows us to detect anomalies throughout the Earth's mantle, but we're still uncertain about their nature or the materials responsible for the patterns we've discovered," Schouten remarked. The researchers believe that the anomalies may not stem from a single source, but rather from a combination of various materials and processes. “We think that the anomalies in the lower mantle have a variety of origins,” says Schouten. “It could be either ancient, silica-rich material that has been there since the formation of the mantle about 4 billion years ago and has survived despite the convective movements in the mantle, or zones where iron-rich rocks accumulate as a consequence of these mantle movements over billions of years” he notes. Questioning established beliefs This research questions established beliefs and paves the way for a more detailed understanding of the dynamics within the Earth's interior. It hints at a complex and diverse mantle, richer and more varied and we thought. However, the method’s dependency on seismic data distribution means that some regions, particularly below stable plate interiors, remain underexplored. Furthermore, the results should be confirmed by other studies before we start rewriting the geology books. Integrating FWI with other geophysical and geochemical tools could provide a more comprehensive understanding of mantle dynamics. For example, combining seismic data with mineral physics experiments could help decode the exact composition of high-wave-speed anomalies, distinguishing between thermal and chemical contributions. The study was published in Nature.

I thought the upper teens were cold in the Magic Valley.  I watched this morning as the Twin Falls thermometer bottomed out at 17 degrees.  Rough, yes, but in some parts of Idaho, they would’ve gladly traded places. Mike McFadyen owns a ranch near Fairfield.  Camas County is a bit higher (sometimes by a lot) above sea level.  His temperature settled in at 10 below zero at one point Tuesday morning.  By next Tuesday, it’s likely to be even colder at Mike’s ranch.  And we’ll still be better off than much of the nation.  By Inauguration Day, temperatures in the eastern two-thirds of the lower 48 are expected to be 20 degrees below average. For anyone from Idaho planning to be in Washington for Inauguration Day, expect cold and snowy weather.  There have been some historically cold precedents. The pattern is a continuation of what we’ve been seeing in recent weeks across the continent.  A friend lives near St. Petersburg, Florida.  She woke to a low of 36 degrees on Sunday morning.  That’s rough for people there, but a lot like one of our January daytime highs.  Just remember that the heat and moisture make that state almost unbearable in summer.  It may get hotter here in summer, but the dew point is low. I keep thinking that if we can get through another couple of weeks we’ll be in the clear, but my hopes have been dashed in the past.  A guy I worked with had grown up in Buhl.  He described the weather in southern Idaho as winter until one day in late spring when you suddenly switch to 100-degree highs every day.  Like someone flipped a switch.

Brown - AFP / Getty Images) Elon Musk revealed that both Tesla and SpaceX have allocated resources and staff to assist those affected by the fires in Los Angeles, as residents are forced to evacuate and face the loss of their homes. Musk shared on Sunday evening via X that Tesla and SpaceX staffers are “driving around areas in greater LA/Malibu that are in tough shape with free WiFi, drinks & snacks.” Tesla & SpaceX personnel are driving around areas in greater LA/Malibu that are in tough shape with free WiFi, drinks & snacks https://t.co/304vjlXSoc — Elon Musk (@elonmusk) January 13, 2025 He shared a post from Tesla that outlined a “summary of initiatives” undertaken by the electric vehicle company to assist both its employees and the wider community. Those endeavors proved to be remarkably extensive. Tesla is providing housing accommodations, transportation, and meals for employees who had their homes “lost or destroyed” amid the historic fires. The company successfully restored all Supercharger locations to operation, with the exception of the Pasadena Supercharger, which was situated in the heart of the fire. Beyond those responses, Tesla deployed two Megapack Chargers, which are essentially massive energy storage units that help with grid reliability, on Friday to “relieve congestion in Thousand Oaks for evacuation & families losing power due to Public Safety Power Shutoffs.” The company deployed another unit the next day to Altadena “for first responder support, providing power & Starlink connectivity.” Tesla has dispatched an additional two Megapack Chargers to San Bernardino and is in the process of installing more in the Palisades, the areas that suffered the greatest damage from the recent fires. Mobile Powerwall Units have been set up in Altadena and Topanga Canyon with assistance from various nonprofit organizations to supply power for devices and refrigerators. Additionally, several Cybertrucks equipped with Starlink are stationed across the city, including in Altadena, Pasadena, Zuma Beach, and Malibu. The Cybertrucks are equipped with compartments filled with water and snacks. To put it differently, Tesla, SpaceX, and Musk have made significant efforts to support not just their employees, but also the entire community. Musk did the same after hurricanes destroyed large parts of the southeastern United States a few months back. However, the initiatives in California proceed in spite of some lingering tensions with the state's Democratic leadership. In November, California's Democratic Governor Gavin Newsom unveiled a proposal to provide rebates for electric vehicles, excluding Teslas. This decision has faced significant criticism, with many viewing it as a form of political revenge against a billionaire adversary who has recently allied with the Republican Party. Musk called the exclusion of Tesla “insane,” especially because the company is the only car producer to make electric vehicles in the Golden State, according to a report from the New York Post. In summary, while California's leaders chose to distance themselves from Musk, he remained loyal to the state. Even as Newsom whines about his enemies politicizing the fires, Musk going out of his way to help the state is about as unpolitical a move as he possibly could have made.

To create a miniature Sun on Earth, you'll require a significant amount of robust metal — and plenty of it. View pictures in App save up to 80% data. Scientists in the UK have forged 5.5 tonnes of a new kind of steel capable of withstanding the searing heat and intense neutron radiation of nuclear fusion, the same reaction that powers the Sun and stars. The breakthrough is another boost to Europe’s growing flock of fusion energy startups. A working group known as NEURONE, part of the UK Atomic Energy Authority (UKAEA), has successfully developed reduced-activation ferritic-martensitic steel, commonly referred to as "RAFM." This achievement represents the first instance of RAFM being manufactured on an industrial scale within the UK. “This is really positive and potentially has relevance for all fusionenergy projects,” Ryan Ramsey, COO at British startup First Light Fusion, told TNW.    Fusion reactors heat hydrogen atoms to very high temperatures, creating a charged state of matter known as plasma. By employing magnetic fields or lasers to compress this plasma, they induce the fusion of atoms, resulting in the release of vast amounts of energy that can be harnessed for electricity generation.  In a fusion energy reactor, the plasma can soar to astonishing temperatures of 150 million°C, momentarily turning these machines into the hottest locations in our solar system. To prevent the plasma from touching the metal walls, massive magnets are employed to keep it suspended in the air. The walls themselves are cooled to prevent them from becoming too hot, but standard steel simply cannot withstand the extreme conditions.  Ramsey stated, “The primary issue isn't the heat itself, but rather the damage caused by neutrons.” Neutron radiation can rapidly compromise the inner structures of a nuclear reactor. "If you can't handle that, you'll find yourself frequently shutting down the fusion reactor to replace the walls, which results in a loss of power generation during those periods," he clarified.    View pictures in App save up to 80% data.

NEURONE has developed a new type of steel that can endure significant neutron exposure and temperatures reaching as high as 650°C, which could enhance the operational efficiency of upcoming fusion power plants.  For startups such as Oxford University spinout First Light, this development represents a significant advancement towards the ambitious objective of creating a commercially viable fusion reactor.   NEURONE utilized an electric arc furnace to forge the steel, relying on electricity rather than coal, located at the Materials Processing Institute (MPI) in Middlesbrough. According to UKAEA, this innovative forging technique could reduce the cost of producing RAFM by as much as 10 times compared to previous methods.  David Bowden, the leader of the NEURONE programme, stated, “Producing 5.5 tonnes of fusion-grade RAFM steel establishes a strong basis for the affordable manufacturing of this type of fusion steel in future commercial fusion initiatives.”   Despite huge progress, fusion energy has always seemed to be that “20-years-away” technology. But the tides might be changing. According to a poll at the International Atomic Energy Agency’s (IAEA) forum in London last year, 65% of industry insiders think fusion will generate electricity for the grid at a viable cost by 2035, and 90% by 2040.

The Amazon River flows in a generally eastward direction, but there are instances when it appears to flow backwards. This phenomenon is primarily caused by extreme weather events, particularly heavy rainfall and flooding, which can create temporary reversals in the river's flow. Additionally, the effects of tectonic activity and sediment deposition over time can also influence the river's course. Understanding these factors helps explain the dynamic nature of one of the world's largest river systems.

While studying river sediment flow, a geology student stumbled upon something quite strange. View pictures in App save up to 80% data. The Amazon rainforest in its current state. Photo credit: Jhampier Giron M/Shutterstock.com The Amazon River holds the title of the largest drainage system globally, both in terms of water volume and its extensive drainage basin. Spanning approximately 6,400 kilometers (or 4,000 miles), this mighty river originates in the Andes Mountains of Peru, traverses the South American continent, and ultimately discharges into the Atlantic Ocean. Interestingly, a remarkable discovery made in 2006, along with further geological research, revealed that this has not always been its course; millions of years ago, the river actually flowed in the opposite direction.  Russell Mapes, a graduate student studying geology at the University of North Carolina, was exploring the movement of river sediment from the Andes Mountains to the Atlantic Ocean when he stumbled upon a puzzling discovery. While examining sedimentary layers in central South America, he unearthed ancient zircon gemstones that appeared to originate from the east, contradicting the expected flow from the younger Andes to the west. “All along the basin, the ages of the mineral grains pointed to very specific locations in central and eastern South America," Mapes explained in a statement at the time. It's quite peculiar, considering that the Amazon is well-known for its flow from West to East rather than the reverse. So, what could have caused these ancient zircon deposits to move from East to West? This isn't the sole indication suggesting that the river might have once flowed in the opposite direction; fossils of marine creatures typically associated with seawater have also been discovered in regions where their presence seems unlikely. Looking into it further, the team determined that the Amazon river really did flow in the opposite direction in the past. That team put the reversal down to a highland area in northeastern South America, which formed during the Cretaceous Period between 65 and 145 million years ago. Drew Coleman, Mapes' supervisor, clarified, "The Amazon's landscape is so level that even a slight tilt in either direction can lead to significant changes." Researchers proposed that prior to the formation of the Andes, the existing gradient led the river to flow from East to West, directing its waters towards the Purus Arch, while the waters on the western side of the arch moved towards the Pacific Ocean. This team contended that as the highlands in the northeast underwent erosion, the flow of water shifted to the opposite direction. With the rise of the Andes, a basin emerged between the mountains and the arch. Eventually, this basin filled up and overflowed, establishing the current flow direction we observe today. Mapes noted, “We believe this recent shift occurred in the last five to ten million years, which is quite rapid in geological terms. This highlights the ephemeral nature of the Earth's surface.” While this was a reasonable hypothesis, a later model in 2014 suggested that the rise of the Andes caused them to intercept more clouds, and the subsequent flow of rain caused erosion, resulting in the Pebas wetlands. Eventually, on timescales which fit with the reversal around 10 million years ago, sediment buildup raised the area, resulting in the reversed flow of the Amazon river. Further research is expected to clarify the precise mechanism behind the reversal, but current evidence indicates that the mighty Amazon River once flowed in the opposite direction.

Scientists stumble upon a surprising finding in their efforts to enhance desalination processes: 'Remarkably convenient and budget-friendly'

2025-03-15 04:20:16

View pictures in App save up to 80% data. The earlier benchmark for seawater was 8% less than that of pure water, marking this as a significant milestone. Researchers at the University of South Australia have made a major breakthrough in addressing global water scarcity, according to Tech Xplore. While more than 70% of the Earth's surface is water, most of it resides in the oceans, making it unsuitable for drinking. Currently, approximately 36% of the world's population lacks access to freshwater for a minimum of four months annually, and this figure could potentially double in the next few decades, according to Tech Xplore. Still, the ocean blue presents an opportunity: seawater can be evaporated, stripped of the high salt content that makes it unusable, and then turned into safe, drinkable water.  Would you consider installing hydropanels for water collection on your house? Absolutely! I'm uncertain. Absolutely not! If the funding comes from the government Select your option to view the outcomes and share your thoughts. The problem with this thermal desalination method has always been the large amount of energy it needs and the slow rate of evaporation. That's where the study's findings, published in the Advanced Materials journal, come in.  The researchers successfully increased the evaporation rate of seawater, achieving a rate that is 18.8% greater than that of pure water. Previously, seawater's evaporation rate was 8% lower than that of pure water, marking this development as a significant milestone, according to Tech Xplore. In order to achieve this remarkable result, scientists introduced a mixture of minerals into the tank containing evaporating seawater. Professor Haolan Xu, one of the authors of the research, explained that the resulting chemical reactions involve an exchange of ions at the interface of air and water, which accelerates the evaporation process, as reported by the outlet. Check it out: Would you consider wearing a shirt crafted from oysters? In addition to the improved efficiency, the minerals are both easily accessible and affordable, which contributes to the overall convenience and cost-effectiveness of the process, Professor Xu explained to Tech Xplore.  With about 17,000 desalination plants worldwide, this breakthrough can have an immediate impact in boosting the amount of clean water available to those who need it — although there are environmental drawbacks to consider. Researchers hope to continue pushing the speed of evaporation in the future to further secure the global water supply, Tech Xplore reported. According to Prof. Xu, as reported by Tech Xplore, "This innovative approach can be seamlessly incorporated into current evaporation-driven desalination technologies, significantly increasing the availability of clean water for billions around the globe."

Unveiling the Remarkable Strength of Celtic Women and Their Daughters

2025-03-27 08:24:22

Bournemouth University View pictures in App save up to 80% data. Numerous female skeletons were discovered interred alongside precious items such as pottery. New research suggests that women in Britain 2,000 years ago may have transferred land and wealth to their daughters rather than their sons, indicating that communities were organized around maternal lineage. Skeletons discovered in Dorset revealed DNA evidence indicating that Celtic men relocated to reside with the families and communities of their wives. Researchers discovered indications of an entire community that developed over generations centered on the female lineage of a family, likely tracing back to a single woman. "According to Dr. Lara Cassidy, the lead author of the study from Trinity College Dublin, this suggests that during the Iron Age in Britain, women held significant power and were capable of influencing the society's direction in various aspects." Bournemouth University View pictures in App save up to 80% data. The archaeologists were thrilled to discover skeletons remarkably well-preserved in the clay soil of Dorset. This marks the first documented instance of communities forming around women in ancient European history. Researchers suggest that the communities likely devoted significant resources to their daughters, anticipating that they would inherit their mothers' social standing. Dr. Cassidy remarks, "While it's quite uncommon in today's societies, this may not have always been true." The team discovered indications that it occurred in various locations across Britain, implying that it was prevalent. The communities examined thrived during the era of Boudica, the warrior queen who spearheaded a revolt against Roman forces in East Anglia circa AD 61. Dr. Cassidy analyzed the DNA extracted from the skeletal remains of 57 members of a tribe known as the Durotriges. This group inhabited Winterborne Kingston in Dorset during the period spanning from 100 BC to AD 100. A team of archaeologists from Bournemouth University excavated the skeletons from a burial site. Through the analysis of mitochondrial DNA, which is inherited exclusively from mothers, Dr. Cassidy discovered that the majority of women in the community share a familial connection that stretches back several generations. In contrast, the Y chromosomes exhibited significant diversity, which is inherited from father to son, suggesting that men from various families integrated into the community through marriage. Bournemouth University View pictures in App save up to 80% data. The remains of individuals from the Durotriges tribe were remarkably well-preserved. The DNA examination suggests that the majority of the ancestral lineage can be traced back to one particular woman. The findings suggest that this society operated under a matrilocal structure, where a husband would relocate to reside within his wife's community. Dr. Cassidy states, "One of the most apparent advantages for a woman is that by staying at home, she maintains her support network. Her parents, siblings, and family members remain close by." "Your husband is the one entering the picture; he is the unfamiliar face in the community and relies on your family for his support and land," she continues. The researchers discovered similar evidence of matrilocality in skeletal remains from additional burial sites, including those located in Cornwall and Yorkshire. She argues that instances of influential women in ancient societies have frequently been overlooked as isolated cases rather than the standard, but these discoveries call that perspective into question. Archaeologists Professor Miles Russell and Professor Martin Smith discovered additional proof indicating that women held a significant status. Bournemouth University View pictures in App save up to 80% data. Researchers from Trinity College and Bournemouth conducted excavations and analyses on the remains of 57 individuals. "We find quite elaborately furnished graves with high status objects of wealth. Every time we find that, it occurs in women's graves, so we think wealth was being transferred down the female line," says Prof Martin Smith at Bournemouth University. The results also support ancient Roman texts that indicated women in Britain held considerable power, arguably even greater than that of their counterparts in Rome. However, Romans such as Julius Caesar considered that to be a mark of primitiveness. "According to Professor Miles Russell from Bournemouth University, 'Women in Britain held significant power, contributing to a more egalitarian society. This was a major issue for the Romans, who lived in a highly patriarchal culture. To the Romans, this characteristic made the Britons appear as the epitome of barbarism.'" Most societies today follow a patrilocal structure, where women relocate to the communities of their husbands. However, certain matrilocal communities can still be found today or have existed in the recent past, such as the Akans in Ghana, West Africa, and the Cherokee in North America. Researchers suggest that Iron Age Britain might have been matrilocal, as men were often absent due to warfare. Dr. Cassidy likens it to World War II, a time when women experienced an increase in their political and economic influence. According to her, matrilocal societies tend to have a lower likelihood of facing internal conflicts. "It has the potential to foster a sense of togetherness among nearby communities and villages. By separating clusters of related males, it prevents the formation of deep bonds and the onset of conflicts with neighboring related males," she proposes. The results have been released in the scientific publication Nature. Follow Georgina on Blue Sky.

NASA's Metallic Spheres: The Unexpected Briefing That Went Under the Radar

2025-03-30 21:23:07

View pictures in App save up to 80% data. On July 1, 2023, a Pentagon official at NASA headquarters calmly stated, ‘We see these metallic spheres all over the world, making maneuvers we can’t explain…moving at Mach 2 against the wind, with no apparent propulsion.” During a briefing where the Pentagon and NASA presented their findings after a year of research, a government scientist spoke about objects that challenge the fundamental principles of physics. This should have dominated the headlines. Yet, it scarcely registered in the mainstream media. NASA’s Briefing: Key Details & Quotes You can watch the entire briefing here on Youtube. All of the quotes that I am using will be time-stamped, when possible. Dr. Sean Kirkpatrick, the head of the Pentagon's All-domain Anomaly Resolution Office (AARO), was straightforward and direct in his approach. Showing a video of a metallic sphere captured by military sensors, he stated matter-of-factly: “This is a typical example of the thing that we see most of… Then came the kicker that should have sent shockwaves through the scientific community: “We see these all over the world, and we see these making very interesting apparent maneuvers.” [36:12–36:29] Hold on...what did you just say? Here is a top government official, speaking at NASA headquarters, describing something that defied our understanding of physics: metallic spheres — as he clearly said in an example — “moving at Mach 2 against the wind with no apparent propulsion.” [1:03:41–1:03:55] That’s twice the speed of sound. Into the wind. With no visible engines. Dr. Kirkpatrick noted that they now have over 800 cases, [54:51–55:06] and that of these cases.- “The numbers I would say that we see are possibly really anomalous are less than single digit percentages… maybe two to five-ish percent.” While it may seem like a limited figure, there are still approximately 20 to 40 unusual instances involving metallic spheres, many comparable in size to small cars, capable of moving at impressive speeds without any visible method of propulsion. Investigating the Spheres This image was included in a presentation that was shared during the public briefing. Size: About as big as a small car (3–13 feet across) Altitude: Flying in the same airspace as commercial planes (10,000–30,000 feet) Appearance: Metallic, spherical, solid Movement: Could hover motionless, then accelerate to incredible speeds Technology: No visible engines, no heat signature, no exhaust Here’s what makes this truly strange. They are admitting that these objects, which by all laws of physics known to humans, shouldn’t be able to fly…are able to hover, and then accelerate to speeds up to Mach 2. Picture a fighter jet from Top Gun, suspended quietly in the air, before it suddenly bursts into action, soaring to its maximum velocity. Devoid of any engines. Again — “We see these all over the world,” Kirkpatrick said. Notice his choice of words: “We see these.” Present tense. Not “We saw these once” or “Someone reported seeing these.” [36:16–36:29] He’s talking about an occurrence that takes place regularly and consistently across the entire world. The Rational QuandaryAre we possibly observing technology that is not of human origin? Occam's Razor suggests that the most straightforward and elegant explanation is often the one that aligns most closely with reality. When unusual phenomena show up in our skies, it's only logical to seek straightforward explanations. Let's take a cue from NASA's experts and analyze each potential cause with a balanced yet discerning perspective. Could these be conventional aircraft? No. They need huge engines to fly. Natural phenomena? No. NASA’s Dr. Fox emphasized, they’re dealing with solid objects showing “signatures that could be anomalous.” That’s scientist-speak for “things that shouldn’t be able to do what they’re doing.” Secret military technology? This is what some people hope it could be. But no country would test their most advanced tech over other nations’ sensitive facilities. And, even more important, these orbs have been appearing for decades. No one had anything close to this kind of technology 40 years ago. The Topic Everyone Avoids Talking About This leads us to a topic that many scientists find challenging to address: technology created by non-human entities. This is where the discussion becomes captivating. This hypothesis aligns perfectly with all the available evidence: Advanced technology beyond our current capabilities? Check. Global presence? Check. Consistent characteristics over decades? Check. Ability to operate without conventional propulsion? Check. Is this a satisfying conclusion? No. Does the technological evidence support it? Yes. A Concise Historical Overview What makes NASA's ongoing research particularly intriguing is that these metallic spheres are not a recent discovery. They align with a series of observations that have been recorded over many years: WWII pilots called them “foo fighters” Navy crews tracked them underwater in the 1950s Commercial pilots have quietly reported them for years The same traits continue to emerge: Metallic spheres Impossible maneuvers No visible propulsion Strategic locations Apparent intelligence Reaching this conclusion isn't easy. As I examine the facts, I can't help but feel, “This isn't as enjoyable as I anticipated. The possibility of non-human technology existing is somewhat…alarming.” I have always been fascinated by the concept of "non-human technology." If it turns out to be real, it could fundamentally alter our perception of reality. It's as though all those hypothetical "what if" discussions have suddenly transformed into reality. This is no longer just a fringe rumor or a conspiracy theory; it has now become verified information regarding objects performing the unimaginable in our atmosphere. When NASA verifies the presence of anomalies such as these metallic orbs worldwide, it leads to significant changes. What are our next steps from this point? So what are NASA's next steps? Dr. Spergel, former head of Princeton’s astrophysics department, emphasized the necessity for improved data. He highlighted the need for additional sensors and more stringent data collection techniques if we are to find the answers we seek. In the meantime, Dr. Nicola Fox acknowledged that researchers investigating these phenomena encounter significant harassment, which exacerbates the existing stigma. It’s disheartening, especially when leading experts are candidly stating, “We observe anomalies that elude explanation,” yet the public discourse continues to be mired in outdated skepticism. To me, this presents a chance to investigate these observations with a new perspective, unburdened by the typical mockery. Should NASA's findings indicate that advanced technologies beyond our current capabilities could have existed in the past, it suggests that some of the ancient technological enigmas may not be as puzzling as the various contradicting theories suggest. While it may seem like a bold conclusion, it's worth noting that NASA's revelations regarding extraordinary flight maneuvers were similarly groundbreaking. The Design I’ve spent the past few months investigating this connection between NASA’s modern metallic orbs and historical technological anomalies. The pattern that emerged was so compelling that I’ve documented it in my upcoming book “The Design: from ‘Drones’ to NASA’s Orbs to Ancient History.” [Link if interested in checking it out] From the meticulous construction of Puma Punku in Bolivia to the enigmatic wisdom found in ancient locations, we are uncovering signs of technological disparities that appeared in the past...similar to the mysterious metallic orbs we encounter today. By leveraging NASA's latest observations as a basis, we can now explore these historical enigmas from a fresh perspective.

The Prototype: Research Indicates AI Tools May Diminish Critical Thinking Abilities

2025-03-31 16:01:38

In this week’s edition of The Prototype, we look at how too much reliance on AI assistants could make it harder to think, a company building bioengineered arteries, the role viruses play in Alzheimer’s and more. You can sign up to get The Prototype in your inbox here. New AI tools are slowly becoming ubiquitous, being added to the software and hardware we use every day (sometimes whether we like it or not). But if we’re using artificial intelligence to perform tasks, search for information and solve problems, what does that mean for the intelligence we’re born with? To figure this out, a team of researchers conducted a study involving 666 individuals ages 17 and up, representing a diverse population. It first evaluated the extent to which each of them made use of AI tools, then tested their critical thinking skills. The results of the study, which were published in the journal Societies, found that those who used AI tools a lot showed worse critical thinking abilities than those who didn’t use them often or at all. Whether someone used AI tools was a bigger predictor of a person’s thinking skills than any other factor, including educational attainment. This occurs due to a process known as "cognitive offloading," wherein individuals outsource their thinking and problem-solving tasks. Regular reliance on cognitive offloading can diminish one's capacity for independent thought and problem resolution. The authors of the study noted, "This dynamic highlights the dual nature of AI technology. Although it boosts efficiency and ease of use, it unintentionally cultivates a reliance that may weaken critical thinking abilities as time goes on." These results align with previous research indicating that AI tools may adversely affect critical thinking abilities. Nevertheless, the authors highlight that some studies suggest these tools can be advantageous when they support critical thinking instead of replacing it. "Further research should investigate methods to incorporate AI tools in ways that boost cognitive involvement rather than obstruct it," they stated. "It is essential to prepare the upcoming generation with the skills needed to maneuver through a progressively intricate digital environment." Keep watching for updates. Ready-Made Bioengineered Arteries for Trauma Victims Every year, thousands of Americans receive traumatic injuries that damage the arteries that crucially carry blood to their limbs. When these occur, patients basically have three options, Laura Niklason, CEO of regenerative medicine startup Humacyte, told me: they can have a vein grafted from another part of their body, which takes extra time and causes additional trauma; the surgeon can replace the artery with a synthetic plastic one, which creates a high risk of infection; or the limb can be amputated. Niklason presents a fourth alternative: her company has created a bioengineered artery known as Symvess, which can be surgically inserted into a patient’s body. This innovative solution aids in preserving the limb while also minimizing the chances of infection. Symvess is made from human donor cells cultivated in a laboratory on a biodegradable scaffold, produced in batches of 200. As time progresses, these cells reconstruct the physical framework of a blood vessel. After this process is complete, the living cells are removed, leaving behind the artery structure that can be safely implanted in a new patient without the risk of rejection. Subsequently, the cells from the patient's body fill the implant, effectively regenerating a new artery. Last month, Symvess was approved by the FDA for use in patients with traumatic injuries. That approval was based on studies that showed that the product, which has been implanted in over 600 patients so far, is significantly less likely to cause infection or lead to limb amputation compared to conventional synthetic arteries made from plastic. In its upcoming initiatives, the company plans to collaborate with Medicare and private insurance providers to secure coverage for transplant procedures involving Symvess. Additionally, it is undertaking research to explore the application of Symvess in patients undergoing kidney dialysis and those suffering from pulmonary arterial hypertension. Furthermore, the company is in the process of creating a more compact version of its product, which may be suitable for heart bypass patients. "This technology is genuinely unprecedented, and the FDA required extensive data review before they felt assured enough to approve it," remarked Niklason. "I’m really pleased to be part of this." WEEKLY DISCOVERY: DORMANT VIRUSES COULD TRIGGER NEURODEGENERATIVE DISEASES It’s long been known that repeated head injuries can lead to neurodegenerative diseases like Parkinson’s, Alzheimer’s and CTE. But it wasn’t clear exactly how that happened. New research suggests the answer may be dormant viruses, particularly herpes simplex 1, which is found in the brains of over 80% of the population. These findings were reached by growing small tissue models of the brain, some with the herpes virus and some without, which were then struck repeatedly with a piston to mimic concussion. The study, which was published in Science Signalling, found that the brain tissues with the virus developed signs of Alzheimer’s disease, while those without did not, and that the damage was markedly increased with repeated blows. The researchers plan to conduct future studies that explore whether exposure to antiviral or anti-inflammatory drugs shortly after an injury could help prevent the onset of Alzheimer’s. LAST BOUNDARY: TESTING WATER-BASED PROPULSION SYSTEMS Japanese startup Pale Blue announced it has signed a deal with Italy-based company D-Orbit to conduct two demonstrations in-orbit of its new ion thruster, which allows satellites both to maneuver and to take themselves out of orbit at the end of their life. Pale Blue’s thruster uses water as a propellant, which potentially offers a cleaner and more sustainable fuel for small satellites. HERE'S WHAT I WROTE THIS WEEK In my other newsletter, InnovationRx, my colleague Amy Feldman and I covered a number of healthcare stories, including a drug that significantly improves survival for lung cancer patients, the controversy over pulse oximetry technology and a new study that finds that while LLMs are good at answering medical exam questions, they’re much less proficient at making diagnoses from patient conversations. SCIENCE AND TECHNOLOGY BITS My colleague Jeremy Bogaisky reports that online retailers like Amazon and Alibaba are selling technology that protects drones from having their signals jammed or being remotely taken over. Ai startup Anthropic’s new funding round will make all seven of its founders billionaires, write my colleagues Alex Konrad and Phoebe Liu. Researchers developed a technique for refrigerating quantum computers in a way that reduces errors and could potentially make them more reliable. Eating grapefruit can interfere with the action of several kinds of medications, including anti-anxiety drugs and statins. But new research suggests it may be possible to grow a variety of the fruit that doesn’t interfere with prescription drugs. Biologists successfully transplanted chloroplasts–the cells that power photosynthesis– from algae into hamsters, where they successfully functioned for about three days. Scientists at Northwestern University built a battery that uses triphenylphosphine oxide, a common industrial waste product, to store energy instead of metals. PRO SCIENCE TIP: MOISTEN YOUR COFFEE BEANS WITH WATER Here’s an easy tip to enhance the flavor of your morning cup of coffee: add a little water to the beans before you grind them. This isn’t a new idea–among coffee professionals this is known as the “Ross Droplet Technique”–but new research gives scientific backing to the idea. When beans are ground, they build up a static electric charge, which causes clumping and inconsistent extraction during the brewing process. In new research published in the journal Matter, scientists found that the Ross Droplet Technique reduced the static charge during grinding, producing a better-tasting coffee. WHAT'S CAPTURING MY INTEREST THIS WEEK I’ve been listening to the concept album Epic by Jorge Rivera-Herrans. It’s a musical-style adaptation of The Odyssey, telling the tale of Odysseus from the end of the Trojan War until his return home to Ithaca. The album is divided into nine sagas of a few songs each, serving as chapters in the story. It’s an amazing version of one of humanity’s oldest stories, and it’s appropriate for it to be sung–that is, after all, how it was originally presented in the time of Homer. It’s streaming on most of the major music services. ADDITIONAL INSIGHTS FROM FORBES Forbes reports that Eric Schmidt's latest secret initiative is an AI video platform named 'Hooglee'.

Chronology of Life: Ice Ages Provided a Catalyst for Evolution

2025-04-01 07:00:55

View pictures in App save up to 80% data. Evolution resembles a magnificent show on the stage of our planet, where each species shines brightly at various points throughout history. Envision a chronicle detailing the magnificent arrivals and departures of various species—not inscribed on paper or papyrus, but engraved within the bones and shells of ancient beings preserved through the ages. Imagine a timeline that chronicles the evolution of life over the past 500 million years while reaching back nearly 2 billion years. A group of specialists at Virginia Tech has successfully brought this concept to fruition. The scientists performed an in-depth examination of prehistoric life, pushing back the timeline of evolution to almost 2 billion years in the past. Shuhai Xiao, a geobiologist at Virginia Tech, along with his team, examined these corridors of time. The research was particularly focused on marine eukaryotes, which are organisms that have cells with a nucleus. Over time, these beings developed into multicellular life forms, such as animals, plants, and fungi, paving the way for an entirely new era of life on our planet. “This represents the most thorough and current examination of this era thus far,” stated Xiao. “Furthermore, we employed a graphic correlation tool that enabled us to attain enhanced temporal resolution.” A tale carved through the sands of time The scientists have traced the origins of life forms to the Proterozoic Eon, a period that spans from 2.5 billion to 539 million years ago. During this era, life forms such as sea sponges were typically smaller, more gelatinous, and less abundant. The majority of these organisms had not yet developed mineralized skeletons, resulting in a scarcity of fossils for us to discover in the present day. Xiao and his team depict this journey through life as a dynamic dance of various species, with the intricate choreography revealing essential understanding of the simultaneous evolutionary trajectories of both life and our planet. The Dull Billion and the glacial periods An intriguing trend identified in the research was the presence of a relatively uneventful timeframe referred to as the “Boring Billion” (from 1.8 billion to 720 million years ago). During this era, it was believed that eukaryotic diversity remained fairly constant, indicating a more gradual rate of evolutionary change. The researchers observed that "Eukaryotic species during the 'boring billion' might have experienced a slower rate of evolution and enjoyed a longer existence compared to those that emerged afterward." Next, a dramatic turn unfolds in the story – the catastrophic Snowball Earth event, which enveloped the planet in ice on at least two occasions between 720 million and 635 million years ago. This cold snap marked the beginning of a period of heightened evolutionary activity, transforming the previously slow and uneventful pace into a steady rise in the diversity of species. Xiao attributes the ice ages as a significant influence that reshaped the course of evolution regarding diversity and dynamics. “Following glaciation, we observe a swift change in eukaryotic species. This is a key discovery.” Fresh inquiries arise from timeless discoveries. These trends raise numerous inquiries for upcoming studies. What factors contributed to the sluggish pace of evolution during the “Boring Billion”? What elements contributed to the rapid acceleration of evolution following the snowball ice ages? Were shifts in environmental conditions, heightened atmospheric oxygen levels, or competition among species significant factors in this evolutionary surge? These inquiries are essential for grasping the intricate relationship between life on our planet and the planet itself. With the findings from this new research and the comprehensive life chart, we are making strides toward deciphering the enigmas of ancient evolution. This intriguing study not only enhances our comprehension of evolution but also paves the way for new avenues of scientific exploration. By charting almost 2 billion years of the history of life, researchers can more effectively link changes in biodiversity to environmental and geological shifts, providing valuable understanding of how life evolves in response to changes on Earth. Additionally, the comprehensive timeline offers a structure for investigating the beginnings of multicellular life, the development of intricate ecosystems, and the possibilities of extraterrestrial life. By studying the evolution of life on Earth across various environments, scientists can enhance their models for detecting biosignatures on extraterrestrial planets. As Xiao and his team progress in their research, this comprehensive evolutionary chart will become an essential tool for future investigations, linking Earth's prehistoric era with its vibrant present.

Fossils from Japan, believed to be 20,000 years old and linked to early humans, have revealed surprising insights that challenge previous assumptions.

2025-03-26 13:44:19

The bone fragments were previously believed to be among the oldest human fossils discovered in Japan. View pictures in App save up to 80% data. An image depicting a bear fossil. New research reveals that the fossilized bones of "Ushikawa Man," believed to be among Japan's oldest human remains dating back 20,000 years, are not what scientists originally thought. Rather, they belong to the skeletal remains of a prehistoric bear. The fossils were found in the late 1950s in the city of Toyohashi, about 140 miles (225 kilometers) southwest of Tokyo. But Gen Suwa, an anthropologist at the University of Tokyo who led the new project, told Live Science that doubts about the Ushikawa fossils were first raised in the late 1980s, and had continued since then. The new research, published Dec. 1, 2024 in the journal Anthropological Science, shows beyond a doubt that the bones are from an ancient brown bear, Suwa said in an email. He noted that bear bones were seldom discovered in archaeological sites in Japan from that period, which meant that Japanese researchers—including the paleontologists who unearthed the fossils in the 1950s—had a rather restricted comprehension of the appearance of bear bones. Nevertheless, Suwa mentioned that these researchers had produced "thorough and highly precise" descriptions and had gathered a significant quantity of fossilized skeletal remains over many years.

Recent studies have revealed that the fossils known as Japan's "Ushikawa Man," which were previously believed to belong to a human from over 20,000 years ago, actually originated from a bear. Ancient skeletons in Japan The fossils are referred to as the Ushikawa fossils, named after the Ushikawa area in Toyohashi, where they were discovered in a quarry between 1957 and 1959. According to Suwa, Japanese researchers of that era believed that another bone fragment, called "Akashi Man," represented the oldest human fossil found on the Japanese mainland, estimated to be over 780,000 years old. Unfortunately, this fossil was lost during an Allied air raid over Tokyo in World War II. In the 1980s, an examination of a plaster cast of the Akashi fossil, which had been lost, suggested that it was likely a piece of a modern human arm bone that had been displaced into a different archaeological layer and subsequently mineralized. This discovery sparked increased interest in the Ushikawa fossils, according to Suwa. The Ushikawa fossils were initially presented as a humerus bone from the upper arm and the end or head of a femur bone from the leg of a human who had lived more than 20,000 years ago. But in the new study, a visual examination and computed tomography (CT) scan revealed that the supposed human humerus was probably the radius bone from the forearm of a brown bear (Ursus arctos) from about that time, while the head of the femur was also determined to be from a bear, Suwa said.

Ancient fossils The discovery that the Ushikawa fossils are not human means the oldest human fossils found on the Japanese mainland are from a limestone quarry near the Japanese city of Hamakita, about 25 miles (40 km) east of Ushikawa. The remains include pieces of a human femur, humerus, clavicle, and cranium, believed to belong to two distinct individuals—one dating back approximately 14,000 years and the other around 17,000 years. Human fossil remains have also been found on Japan's Ryukyu Islands — also known as the Nansei Islands — situated about midway between Japan and Taiwan. Scientists think the youngest of these fossils date from about 18,000 years ago, while the oldest may date from up to 32,000 years ago. The latest finding in Japan is not the first time that human and bear bones have been confused: A bone found in a cave in Alaska in the 1990s was once thought to be from a bear, but new research has shown that it is from a Native American woman who lived about 3,000 years ago.

Helicopter Retrieves Artifact from NASA Armstrong Rooftop

2025-03-25 16:35:43

Jay Levine NASA Armstrong Public Relations Specialist View pictures in App save up to 80% data. NASA/Lori Losey What do the X-15 and the space shuttles have in common? Information from the rocket plane and the spacecraft, as well as many experimental aircraft, were tracked from a pedestal and telemetry dish during key eras in flight history at or near NASA’s Armstrong Flight Research Center in Edwards, California. When the NASA facility’s administration Building 4800 was built in the 1950s, the infrastructure was included to anchor the rooftop pedestal and dish as the primary way to gather data from aircraft during flights. It was retired in 2015, but a recent roofing project enabled relocation of the artifact to a new place of honor for its support of many experimental aircraft such as the lifting body aircraft, the reverse swept wing X-29, and the highly maneuverable X-31. "Collecting telemetry data from aircraft during missions is fundamental to our operations. One significant benefit of placing the telemetry antenna on the roof in the initial stages was its close proximity to the back ramp," explained Bob Guere, chief of NASA Armstrong Range Operations, while discussing the space where aircraft move from the hangar to the flightline. "This allowed us to conduct ground tests and evaluate the planes prior to taxiing without needing to rely on telemetry antennas located at a greater distance." View pictures in App save up to 80% data. On October 4, 2024, a cable is anchored to a rooftop pedestal at Building 4800 within NASA's Armstrong Flight Research Center in Edwards, California. This pedestal, which has been readied for a helicopter lift to take it off the roof, served its purpose from the 1950s until 2015, facilitating various telemetry dishes in gathering data from research aircraft. The rooftop pedestal played a crucial role in the initial development of the center, and its renovation in 2003 revitalized its significance. This upgrade also involved obtaining certification to comply with the landing standards of the Space Shuttle Program. “When a space shuttle was re-entering the atmosphere, it flew over Edwards,” Guere explained. “Telemetry antennas situated on the hillside near NASA Armstrong monitored the descent, capturing reflections against a backdrop of dirt and concrete. The rooftop antenna, positioned closer to the ground, had a clear view as the orbiter approached for landing, making it an ideal link for shuttle landings.” The pedestal and dish remained in place after decommissioning due to expenses. Currently, using a helicopter to extract the pedestal from the roof has become the most cost-effective solution, especially as part of a larger initiative aimed at re-roofing Building 4800. According to Bryan Watters, the NASA Armstrong roof project manager, the planning for the helicopter lift of the pedestal took an entire month, in addition to the time required to secure airspace operations and landing permits from the Air Force for the removal project.

This pedestal has been in use since the 1950s until 2015, serving as a platform for various telemetry dishes that gathered data from research aircraft. The pedestal and riser stood 16 feet above the rooftop, supporting a mechanism that allowed the 12-foot dish to rotate. Together, the pedestal and dish weighed approximately 2,500 pounds and were taken down in separate operations. Before the helicopter's arrival on October 3, crews inspected the eight bolts securing the pedestal and dish to the roof's infrastructure. The next day, following further briefings, the helicopter was stationed above Building 4800, where a cable was lowered and fastened to the pedestal. After ensuring it was securely attached, the helicopter gradually ascended, transporting its passenger to the southern side of the building. Once there, the passenger was detached from the cable and moved to a nearby warehouse for safekeeping. Meanwhile, roofers dismantled the steel platform that had supported the pedestal to ready the site for the installation of new roofing materials. Authorities have yet to decide on the location for the pedestal's display. There are multiple possibilities for positioning the pedestal and dish alongside the renowned retired research aircraft showcased at the entrance of NASA Armstrong.

The Webb telescope has recently cracked the 'universe-shattering mystery'.

Credit: SA GSFC / CIL / Adriana Manrique Gutierrez The James Webb Space Telescope might not have broken our understanding of the universe, after all. Previously, astronomers used Webb to spot curious, faint, and extremely ancient red dots that they surmised were giant galaxies. But there was a problem. It shouldn't have been possible for such massive galaxies — the earliest of which formed just some 500 to 700 million years after the universe was created — to have enough material to form copious amounts of stars and solar systems. (The universe is about 13.7 billion years old.) New insights from the powerful space observatory, orbiting 1 million miles beyond Earth, suggest the faint light of these distant "little red dots" is actually generated by active black holes at the center of the galaxies. That means the red light we see isn't coming from the glow of a prodigious number of stars. "This is how you solve the universe-breaking problem," Anthony Taylor, an astronomer at the University of Texas at Austin who co-authored the research, said in a statement. "Nasa clarified, 'In contrast to what some headlines suggest, cosmology is not in disarray,' alluding to previous media reports about the cosmic dilemma." The findings were showcased during the 245th gathering of the American Astronomical Society. Astronomers looked at a wide population of the red objects observed so far, spanning a number of different Webb surveys and elapsing hundreds of millions of years. Around 70 percent of the red objects "showed evidence for gas rapidly orbiting 2 million miles per hour (1,000 kilometers per second)," NASA explained. That's a telltale sign of a strong black hole: Black holes — which are objects wielding extreme gravitational power — amass accretion disks of super-heated, rapidly spinning dust, gas, and particles. If the scientists' findings are accurate, the illumination you observe from the red objects beneath is produced by the black holes located at the core of these ancient galaxies.

Notably, these objects start to show up in significant quantities approximately 600 million years post-Big Bang, only to see a dramatic decrease in their numbers around 900 million years later, which corresponds to 1.5 billion years after the Big Bang. What could be the reason behind this? Are they possibly being hidden from our view? Webb scientists will continue weighing their novel observations with our understanding of how the universe works. Dale Kocevski, an astronomer from Colby College in Waterville, Maine, who spearheaded the research, remarked, "There are often multiple ways to interpret the puzzling characteristics of the little red dots. It's an ongoing dialogue between theoretical models and observational data, striving to achieve a harmony between what corresponds effectively and what contradicts." The remarkable capabilities of the Webb telescope The Webb telescope — a scientific collaboration between NASA, ESA, and the Canadian Space Agency — is designed to peer into the deepest cosmos and reveal new insights about the early universe. It's also examining intriguing planets in our galaxy, along with the planets and moons in our solar system. Here's how Webb is achieving unparalleled feats, and likely will for decades to come: - Giant mirror: Webb's mirror, which captures light, is over 21 feet across. That's over two-and-a-half times larger than the Hubble Space Telescope's mirror. Capturing more light allows Webb to see more distant, ancient objects. The telescope is peering at stars and galaxies that formed over 13 billion years ago, just a few hundred million years after the Big Bang. "We're going to see the very first stars and galaxies that ever formed," Jean Creighton, an astronomer and the director of the Manfred Olson Planetarium at the University of Wisconsin–Milwaukee, told Mashable in 2021. - Infrared view: Unlike Hubble, which largely views light that's visible to us, Webb is primarily an infrared telescope, meaning it views light in the infrared spectrum. This allows us to see far more of the universe. Infrared has longer wavelengths than visible light, so the light waves more efficiently slip through cosmic clouds; the light doesn't as often collide with and get scattered by these densely packed particles. Ultimately, Webb's infrared eyesight can penetrate places Hubble can't. "It reveals the truth," Creighton remarked. - Peering into distant exoplanets: The Webb telescope carries specialized equipment called spectrographs that will revolutionize our understanding of these far-off worlds. The instruments can decipher what molecules (such as water, carbon dioxide, and methane) exist in the atmospheres of distant exoplanets — be they gas giants or smaller rocky worlds. Webb looks at exoplanets in the Milky Way galaxy. Who knows what we'll find? "We might learn things we never thought about," Mercedes López-Morales, an exoplanet researcher and astrophysicist at the Center for Astrophysics-Harvard & Smithsonian, told Mashable in 2021. Already, astronomers have successfully found intriguing chemical reactions on a planet 700 light-years away, and have started looking at one of the most anticipated places in the cosmos: the rocky, Earth-sized planets of the TRAPPIST solar system.

How to observe the rare comet that will be visible from Earth this month

2025-03-17 15:29:23

The universe is brimming with intriguing celestial objects and various marvels, and you could have the chance to witness one in just a few days. If, for some reason, you don’t know the names of every rock moving through the infinite vacuum of space, then you might have missed the upcoming news. Comet G3 ATLAS (C/2024) is on its way, and you could have the chance to see it! Don’t worry if the name doesn’t sound familiar; it was just discovered not long ago. It was discovered in early April 2024 and was the third comet found that month and identified by the facility Asteroid Terrestrial-impact Last Alert System (ATLAS), according to PEOPLE. As for where it came from, Space.com reports that it's believed to have originated from Oort Cloud, which is comprised of millions of tiny icy objects estimated to be 10 trillion miles from the Sun. Nevertheless, astronomers suggest that spotting it in the night sky could be more challenging than one might think. View pictures in App save up to 80% data. The comet is anticipated to shine more brightly than Venus (Getty Stock Image) On January 13, the comet is anticipated to reach its perihelion, signifying that it will be at its nearest position to the Sun. At this time, the comet will come within approximately 8.3 million miles of the Sun. The same day, it's also predicted to reach its closest point to Earth. This time around, many more people can catch a glimpse of it in the clear sky using rather basic technology, binoculars or a telescope - and if visible, it'll look like a bright star with a white or golden color, Space.com says. Although both the Northern and Southern hemispheres will have opportunities to see it, those in the Southern hemisphere will find it easier to catch a glimpse. According to the Sky and Telescope Organization, skywatchers in the Northern Hemisphere might have the ability to spot the comet 'extremely low in the southwestern sky' from about January 15 to 18. The Planetary Society reports that while some experts anticipate the comet may disintegrate as it approaches the Sun, recent studies suggest that Comet G3 has experienced similar encounters before. View pictures in App save up to 80% data. With fairly simple technology, you should be able to identify it (Getty Stock Image) Data indicates that it is estimated to follow an orbit of roughly 160,000 years, suggesting it has undertaken an extraordinary journey. This challenging orbit suggests that the comet has probably endured at least one close encounter with the Sun in the past. While it's tough to predict a comet's visibility, Forbes reports that the comet is said to be shining at -4.5 magnitude, which is brighter than Venus. Although some may view this as a negative indication, comet observer John Bortle shared with Space.com that there have been reports of 'unusual' characteristics, including a 'shadow of the nucleus', which typically does not indicate any disruption. Bortle remarked, "I believe the odds of it surviving are roughly equal, around 50:50." It's definitely worth a try.

Are you able to decipher cursive writing? It's a unique skill that the National Archives is seeking!

Alternatively, there are several million. Over two centuries' worth of U.S. documents require transcription (or at the very least, classification), and the overwhelming majority of these are written in cursive handwriting – necessitating individuals who are skilled in this elegant, looping style of writing. "Being able to read cursive is like having a superpower," remarked Suzanne Issacs, who serves as a community manager for the National Archives Catalog in Washington D.C. She is part of the team that coordinates the more than 5,000 Citizen Archivists helping the Archive read and transcribe some of the more than 300 million digitized objects in its catalog. And they're looking for volunteers with an increasingly rare skill. Those records range from Revolutionary War pension records to the field notes of Charles Mason of the Mason-Dixon Line to immigration documents from the 1890s to Japanese evacuation records to the 1950 Census. View pictures in App save up to 80% data. An application for a Revolutionary War Pension submitted by Innit Hollister in August 1832. The National Archives employs Citizen Archivists, who volunteer their time to assist in transcribing these documents. While proficiency in reading cursive handwriting is beneficial, it is not a requirement. "Issacs mentioned that we organize missions inviting volunteers to assist us in transcribing or tagging records within our catalog." To volunteer, all that’s required is to sign up online and then launch in. “There's no application,” she said. “You just pick a pick a record that hasn't been done and read the instructions. It's easy to do for a half hour a day or a week.” Having the ability to read longhand script is incredibly beneficial, as many documents are composed in that style. "It's not solely about whether you were taught cursive in school; it's really about how frequently you utilize cursive in your daily life," she remarked. View pictures in App save up to 80% data. An application for a Revolutionary War Pension was submitted on April 29, 1852. The National Archives engages Citizen Archivists, who volunteer their time to assist in transcribing these historical documents. Being able to read cursive writing is quite beneficial for this task. Cursive writing has become less common. The ability of Americans to use this interconnected style of writing has been gradually declining over the years. School children were once taught impeccable copperplate handwriting and penmanship was something they were graded on. That began to change when typewriters first came into common use in the business world in the 1890s and was further supplanted in the 1980s by computers. Still, handwriting continued to be considered a necessary skill until the 1990s when many people shifted to e-mail and then in the 2000s to texting. By 2010, the Common Core teaching standards emphasized keyboard skills (once taught as “typewriting”) and no longer required handwriting on the presumption that most of the writing students would do would be on computers. That led to a pushback and today at least 14 states require that cursive handwriting be taught, including California in 2023. But it doesn’t mean that they actual use it in real life. In the past, most American students began learning to write in cursive in third grade, making it a rite of passage, said Jaime Cantrell, a professor of English at Texas A&M University Texarkana whose students take part in the Citizen Archivist work, putting their skills reading old documents to work. View pictures in App save up to 80% data. On January 23, 2024, a student at Orangethorpe Elementary School in Fullerton, California, is seen practicing cursive writing. This year, California grade school students are mandated to learn cursive handwriting as part of their curriculum. For people of her generation, she explained, “cursive represented a milestone in literacy during the 1980s. We mastered cursive and suddenly we could write in the same way that adults did.” She mentioned that although many of her students learned cursive in school, they rarely use or read it. She knows this because she provides feedback on their papers using cursive writing. A few of her students have stopped typing altogether. They now rely on talk-to-text tools or even artificial intelligence. "I can tell because the lack of punctuation makes it flow like a stream of consciousness," she observed. Mastering the cojoined script can be a challenging endeavor, but it is certainly achievable. Doing so grants you access to a treasure trove of historical documents. For many, cursive writing remains a valuable skill. California passed a law in 2023 requiring that “cursive or joined italics” be taught for grades one through six. The law’s author said it was so students could read primary source historical documents. That’s exactly how Cantrell’s students use it. One of the classes she teaches involves deciphering documents written in the 18th and 19th centuries – and one of their projects is to get involved in the National Archive’s transcription work. Cantrell remarked, “There’s definitely a learning curve involved. However, my students persevere. They sense a responsibility and believe they are contributing positively.” Being able to read cursive is just the start to deciphering older documents, said the National Archive’s Nancy Sullivan. The handwriting of the 18th and 19th centuries isn’t what today’s third-grader are taught. "Sometimes, the oldest texts can be the most straightforward to understand," Cantrell remarked. "Examining the correspondence between Abigail Adams and her husband, President John Adams, reveals that the cursive writing is truly an art form; it's remarkably consistent," she remarked. The capabilities of artificial intelligence in understanding cursive writing have their limitations. According to Sullivan from the National Archive, artificial intelligence is beginning to decipher cursive writing, but it still requires assistance from humans. The Archives has collaborated with FamilySearch, a non-profit organization focused on genealogy and operated by the Church of Jesus Christ of Latter-day Saints, which provides complimentary genealogical software, search capabilities, and access to historical records. FamilySearch has created an AI tool designed to interpret handwritten documents. However, a human is still needed to perform the final editing. "Typically, there are a few errors," she explained. "That's why we refer to it as 'extracted text,' and our volunteers need to review it and check it against the original document." It is only after a volunteer has thoroughly examined the text that it is deemed a proper transcription. According to Issacs, AI is not always able to interpret the frequently challenging documents that volunteers encounter. These documents may be damaged, stained, creased, or worn. For instance, when it comes to pension applications from the Revolutionary War, widows needed to validate their marriages, which led them to include handwritten pages of family trees that were often ripped out from their family Bibles. Let's not overlook the issue of poor penmanship. “The handwriting of some Justices of the Peace is dreadful,” remarked volunteer Christine Ritter, 70, a resident of Fairless Hills, Pennsylvania. The document is filled with cross-outs, notes scrawled on the reverse side that seep through, quirky and creative spellings, and archaic letter forms (for instance, a double S might appear as a "long s," resembling an F). Additionally, you'll find children's doodles layered on top. There are also numerous outdated terms and legal jargon that can confuse even the most knowledgeable readers. “It’s like piecing together a puzzle, and I find it truly enjoyable,” shared volunteer Tiffany Meeks, 37. She began her journey as a transcriber in June and discovered a new term – paleography, which involves interpreting ancient manuscripts. “I felt as though I was picking up a completely new language. I was not only revisiting my cursive skills but also my old English,” she remarked. “I discovered a new term: paleography,” which refers to the study of deciphering ancient texts. No cursive? That's perfectly fine! Issacs from the Archive emphasizes that volunteers are not required to have prior knowledge of cursive writing; you can pick it up as you go. "It can be beneficial, but it's not essential." For instance, there is a feature called "no cursive needed" available for individuals examining pension records from the Revolutionary War. Rather than directly reading and transcribing these documents, volunteers have the opportunity to assist by adding "tags" to records that have already been transcribed by fellow Citizen Archivists, making them more searchable. "You can learn it gradually as you progress," Ritter mentioned. "When I received the document for the first time, I was taken aback and thought, 'Wow, this is impossible to read.' It made me anxious. However, as I continued to work with them, it became much more manageable," she remarked. Ritter’s working on Revolutionary War pension files for soldiers who served at the Battle of Guildford Courthouse on March 15, 1781. As she works, she imagines how much it will mean to families to find something so old about one of their relatives. She recalls a time when she took great pride in her impeccable penmanship, but nowadays she describes her handwriting as “terrible.” Nevertheless, she still excels at reading cursive and has turned it into a delightful hobby. "I rise early in the morning and share breakfast with my husband before he heads out for a fishing trip. After that, I retreat to my workspace, where my computer awaits. I tune into my favorite oldies radio station and dive into my transcription work," she shared. "It's something I truly enjoy."

'Siberian Express' Set to Intensify January's Frigid Conditions in Central and Eastern Regions

2025-03-10 19:17:52

View pictures in App save up to 80% data. January has delivered a bitterly cold experience for numerous residents in the central and eastern regions, and the arrival of the "Siberian Express" is set to intensify the icy conditions as we approach the weekend and the upcoming week. First up, a temperature roller coaster this week. A bout of arctic air currently entrenched over the Midwest and Northern and Central Plains will sweep toward the Northeast through Wednesday. Low temperatures will sometimes be 10 to 25 degrees below average into midweek. Following this event, the Plains and Midwest are expected to experience significant warming, with temperatures reaching 10 to 20 degrees above the seasonal norm by Thursday and Friday. This will result in afternoon highs climbing into the relatively mild (for January) range of the 30s and 40s across many regions. View pictures in App save up to 80% data. Present Temperature Readings The "Siberian Express" arrives this weekend. When arctic air spills into the U.S. during winter it can have one of multiple source regions. That includes Arctic Canada, Alaska, and in the case what lies ahead this weekend and early next week, Russia's Siberia region. Sometimes meteorologists call this the "Siberian Express" because of the cold air's geographic origins. Siberia ranks among the coldest places on the planet. For instance, several areas in the region recorded temperatures plunging close to minus 60 degrees Fahrenheit in the 24-hour period leading up to Monday morning in the U.S. Such extreme cold is a common occurrence during the winter months in Siberia. Considering the frigid origins, arctic air from this area can deliver a powerful impact as it moves southward into Canada and the United States. View pictures in App save up to 80% data. How frigid temperatures might become. In general, some locations might see their coldest lows of winter so far, while for others it might rival what they have already seen. Minneapolis may experience its first double-digit below-zero temperature of the season early next week. Chicago and Denver could experience their initial sub-zero temperatures of the season. Please remember that this forecast is several days out, so the low temperatures for Sunday through next Tuesday may change. We will provide more updates on the forecast later this week. Another undeniable fact is that wind chills will once again pose a threat to many starting early next week. View pictures in App save up to 80% data. Next Week's Predicted Morning Lows January's cold start is notable for one reason. Record-setting cold hasn't been widespread this month, but what we've seen so far plus what's to come makes it noteworthy from a persistence point of view. For the first 11 days of the month, temperatures in many regions east of the Rockies were generally below the average, according to NOAA's analysis. Particularly significant was the observation that areas in the Plains, South, Ohio Valley, and mid-Atlantic experienced temperature drops of 5 degrees or more below the norm. Aside from a short warm spell towards the end of this week, most of these regions will still experience the harsh effects of this chilly January trend as we move into the final days of the month.

When you look up at the sky full of fluffy clouds, what do you see? An elephant holding a balloon? Or perhaps a dragon spewing fire? This is nothing strange, as our brains are programmed to recognize familiar patterns and shapes in what we see. The phenomenon, called pareidolia, helps us make sense of the world and avoid danger.Bored Panda gathered many more similar examples where people saw things as other things, assigning meaning when there might not be one. Scroll down to find them, and be sure to upvote the ones that mess with your eyes and brains the most!

More technically, pareidolia is “the illusory perception of meaningful patterns or images of familiar things in random or amorphous data, as a face seen on the moon.” Despite being a universal human trait, the phenomenon remains largely enigmatic. Neuroscientists have gained insights into the brain regions involved, and they believe it is an evolutionary advantage that helped our ancestors recognize faces and detect potential dangers in their environment. #4 Refilling the Soap Dispenser Led to Overnight Growth of Fungal Shapes View pictures in App save up to 80% data. #5 I transformed a burned match into a microphone complete with a stand.

Most commonly, people spot faces and animals in inanimate objects. Our hypersensitivity to detecting faces even has its own category of pareidolia—face pareidolia. In a sense, it can be considered a side effect of our ability to quickly identify human features. This efficiency in detecting faces can sometimes make us see them when they aren’t there. #7 This piece of pine wood features an arrow indicating the location of the tree's center.

In general, pareidolia is a specific form of apophenia, a wider concept that refers to the tendency to perceive patterns or significance in random information. This inclination is a fundamental aspect of human nature, as we seek to establish connections in a world that often appears disorganized and chaotic. However, when this tendency becomes excessive, it may indicate underlying mental health issues such as bipolar disorder, major depression, or schizophrenia, which can cause individuals to disconnect from reality. #19 Discovered an Awesome Stick That Resembles a Great Wizard's Staff.

The ancient popsicle serves as a fascinating time capsule, preserving a glimpse into the distant history of our planet Earth. View pictures in App save up to 80% data. Handling ice core samples at Antarctica's Little Dome C on November 20, 2024  Image Credit: Scoto©PNRA/IPEV In their pursuit of the oldest ice on Earth, researchers have accomplished the impressive task of drilling a 2,800-meter (9,186-foot) ice core, penetrating all the way to the bedrock beneath the Antarctic ice sheet. This remarkable achievement uncovers a continuous climate history of our planet stretching back at least 1.2 million years. The ice core was obtained from a remote site in Antarctica called Little Dome C by researchers from the “Beyond EPICA - Oldest Ice” project, funded by the European Commission. “The right location was identified using cutting-edge radio echo sounding technologies and ice flow modeling. Impressively, we found the record that goes from 0.8 to 1.2 million years ago, exactly where it was predicted to be, in the depth range between 2,426 and 2,490 meters [7,959 and 8,169 feet], extending our previous twenty-year-old EPICA ice core record,” Frank Wilhelms, principal investigator in the field and joint professor at Göttingen University and the Alfred Wegener Institute, said in a statement. Antarctica is covered in extremely chunky ice sheets that sit on top of continental bedrock. The latest expedition by Beyond EPICA has reached the transition point between ice and rock, which could provide important clues about our planet’s past. Ice cores can provide insights into Earth’s climate history because each layer captures atmospheric gases, dust, and isotopic compositions from the time it was formed, allowing scientists to infer past conditions.

Collecting these samples is an enormous undertaking. The team has dedicated more than 200 days to their work on the central Antarctic plateau, situated at an elevation of 3,200 meters (10,498 feet) above sea level, where the typical summer temperature hovers around -35°C (-31°F). Currently, the project faces the challenge of transporting the ice core samples to laboratories for thorough analysis. Gianluca Bianchi Fasani, a senior researcher at ENEA-UTA (National Agency for New Technologies, Energy, and Sustainable Economic Development - Antarctica Technical Unit) and the logistics lead for Beyond EPICA, stated, “The valuable ice cores collected during this mission will be transported back to Europe aboard the icebreaker Laura Bassi, while ensuring the maintenance of the -50°C [-58°F] cold chain, which presents a considerable logistical challenge for the project.”

A rocket needs to reach a speed of approximately 25,000 miles per hour, known as escape velocity, to break free from Earth's gravitational pull. This speed is necessary because it allows the rocket to overcome the gravitational force that keeps it bound to the planet. If the rocket doesn't achieve this velocity, it will not have enough kinetic energy to counteract the gravitational attraction and will eventually fall back to Earth. The escape velocity is influenced by factors such as Earth's mass and radius, and it ensures that the rocket can travel into space without being pulled back.

Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to [email protected]. Why does a rocket need to travel at 25,000 miles per hour (approximately 40,000 kilometers per hour) to break free from Earth's gravity? – Bo H., 10 years old, Durham, New Hampshire There’s a reason why a rocket has to go so fast to escape Earth. It’s about gravity – something all of us experience every moment of every day. Gravity is the force that draws you down towards the Earth, and that's beneficial. It ensures that you remain grounded; without it, you would drift off into the vastness of space. But gravity also makes it difficult to leave Earth if you’re a rocket heading for space. Escaping our planet’s gravitational pull is hard – not only is gravity strong, but it also extends far away from Earth. Similar to an inflated balloon. As a rocket scientist, one of the things I do is teach students how rockets overcome gravity. Here’s how it works: Essentially, the rocket has to make thrust – that is, create force – by burning propellant to make hot gases. Then it shoots those hot gases out of a nozzle. It’s sort of like blowing up a balloon, letting go of it and watching it fly away as the air rushes out. View pictures in App save up to 80% data. On July 16, 1969, the Saturn V rocket launched Apollo 11, carrying three American astronauts on their historic journey to the Moon. Image courtesy of Heritage Images/Hulton Archive via Getty Images. More specifically, the rocket propellant consists of both fuel and oxidizer. The fuel is typically something flammable, usually hydrogen, methane or kerosene. The oxidizer is usually liquid oxygen, which reacts with the fuel and allows it to burn. When launching into space and breaking free from Earth's gravity, rockets require a significant amount of force, leading to rapid consumption of propellant. This poses a challenge, as rockets cannot carry an unlimited supply of fuel to maintain continuous thrust; the quantity of propellant necessary would add excessive weight, preventing the rocket from liftoff. What occurs when the fuel is depleted? The propulsion ceases, and gravity begins to decelerate the rocket, eventually leading it to descend back towards Earth. View pictures in App save up to 80% data. A rocket delivers a lateral thrust (indicated by the right arrow), while gravity exerts a downward force toward Earth (shown by the down arrow). The combination of these forces results in the spacecraft's trajectory (marked by the red arrow), allowing it to achieve orbit (illustrated by the yellow path). ESA/ L. Boldt-Christmas Fortunately, scientists can launch the rocket with some sideways momentum so that it misses the Earth when it returns. They can even do this so it continuously falls around the Earth forever. In other words, it goes into orbit, and begins to circle the planet. Many launches intentionally don’t completely leave Earth behind. Thousands of satellites are orbiting our planet right now, and they help phones and TVs work, display weather patterns for meteorologists, and even let you use a credit card to pay for things at the store or gas at the pump. You can sometimes see these satellites in the night sky, including the International Space Station. NASA's Perseverance rover was launched to Mars aboard an Atlas V rocket. Fleeing from Earth But suppose the goal is to let the rocket escape from Earth’s gravity forever so it can fly off into the depths of space. That’s when scientists do a neat trick called staging. They launch with a big rocket, and then, once in space, discard it to use a smaller rocket. That way, the journey can continue without the weight of the bigger rocket, and less propellant is needed. View pictures in App save up to 80% data. In May 2024, a SpaceX Falcon 9 rocket successfully lifted off from Cape Canaveral, Florida, delivering 23 Starlink satellites into low Earth orbit. Photo credit: Joe Raedle via Getty Images. However, staging alone won't suffice; eventually, the rocket will deplete its fuel. Yet, if the rocket reaches a sufficient speed, it can exhaust its propellant and still glide away from Earth indefinitely, unaffected by gravitational pull. It's similar to biking: if you gain enough momentum, you can ascend a hill without needing to pedal. And just like there’s a minimum speed required to coast the bike, there’s a minimum speed a rocket needs to coast away into space: 25,020 mph (about 40,000 kilometers per hour). Scientists call that speed the escape velocity. A rocket needs to go that fast so that the momentum propelling it away from Earth is stronger than the force of gravity pulling it back. Any slower, and you’ll go into an orbit of Earth. Fleeing from Jupiter Larger or more massive objects exert a stronger gravitational force. Therefore, a rocket taking off from a planet that is larger than Earth would require a greater escape velocity to break free from the planet's gravitational influence. For example, Jupiter is the most massive planet in our solar system. It’s so big, it could swallow 1,000 Earths. So it requires a very high escape speed: 133,100 mph (about 214,000 kilometers per hour), more than five times the escape speed of Earth. But the extreme example is a black hole, an object so massive that its escape speed is extraordinarily high. So high, in fact, that even light – which has a speed of 370 million mph (about 600 million kilometers per hour) – is not fast enough to escape. That’s why it’s called a black hole.

Lemurs Face Extinction Threat, Even with Their Remarkable Genetic Diversity

2025-03-15 17:56:34

View pictures in App save up to 80% data. Sergiy - stock.adobe.com - for illustrative purposes only The development of lemurs is regarded as distinctive since they underwent evolution in complete seclusion on the island of Madagascar millions of years ago. The island boasted a variety of ecosystems, featuring lush tropical forests in the eastern region and arid, dry landscapes in the southwestern part. This resulted in a variety of lemur species, from tiny mouse-sized creatures to massive sloth-like varieties. The lemurs we are familiar with today are small, have large eyes, and inhabit trees. Over 100 species inhabit Madagascar, showcasing significant genetic diversity among them. However, a staggering 90 percent face the threat of extinction. A group of researchers from Spain aimed to uncover the reasons behind the critical endangerment of numerous lemur species, even though they exhibit significant genetic diversity. To achieve this, they analyzed the genomes of 162 lemurs representing 50 distinct species found throughout Madagascar. Their research uncovered the ways in which ecological elements, changes in climate, and recent human actions have influenced the genetic diversity of lemurs throughout history. "According to Joseph Orkin, the lead researcher of the study, 'As climate changes intermittently linked previously isolated environments, lemurs from various species and groups began to interbreed, exchanging genetic material that enhanced their overall diversity.'" "Additionally, it seems that the species with the greatest diversity are those that have fragmented populations spread throughout various ecosystems on the island. This trend of isolation followed by reconnection appears to be enhancing and redistributing genetic diversity across the entire island." Recent human actions have significantly contributed to the decline of lemur populations. Evidence indicates that factors such as deforestation, the growth of human populations, and changes in hunting methods are closely linked to the onset of dramatic decreases in lemur numbers. View pictures in App save up to 80% data. Sergiy – stock.adobe.com – for illustrative purposes only The exact timeline of the first human arrival in Madagascar remains unclear, but it is believed that their population started to increase around a millennium ago. By the 1700s, the island had undergone considerable transformations in its environment. “Upon examining the genetic data related to population decreases, we consistently identified two notable inflection points occurring approximately 1,000 and 300 years ago. It was quite remarkable to observe such a distinct correlation between the periods of human population growth and the reduction in lemur populations,” Orkin remarked. These results may play a vital role in influencing future conservation strategies. The reduction of habitats and deforestation pose significant risks to lemurs by decreasing their population numbers and disrupting the natural links between habitats that facilitated gene flow. In the absence of varied genetic exchanges, the likelihood of inbreeding increases, thereby heightening the risks for species that are already at a disadvantage. Madagascar is just one of many regions worldwide experiencing a decline in biodiversity. The growing human population is driving this issue on a global scale. By increasing our understanding of how human actions impact biodiversity, we can discover more effective ways to safeguard it. The details of the study were published in the journal Nature Ecology & Evolution. More About:Animals

Quadrantid Meteor Shower: A Guide to Viewing the Spectacular Event in UK Skies Tonight

2025-04-08 13:17:50

NASA has labeled the Quadrantids meteor shower, originating from the 2003 EH1 asteroid, as the most impressive meteor display of the year. It remains observable for another two days in areas of the UK with minimal light pollution. View pictures in App save up to 80% data. The Quadrantids meteor shower can be seen in the skies over the UK tonight, but it will only last for the next 48 hours. The best meteor shower of the year will light up UK skies tonight as Brits have another 48 hours to catch a glimpse. The Quadrantids shower is known for its frequent fireballs and is considered by NASA one of the most impressive throughout the year. And while its intensity peaked Friday last week, stargazers still have another two days to see the show before they return. Those lucky to see the shower so far got to se up to 50 meteors an hour. The Quadrantids, unlike most meteor showers which come from comets, originate from an asteroid called 2003 EH1. Beginning on Boxing Day, their peak was on Friday and Saturday last week, but they will remain visible in UK skies until Sunday. And while fancy stargazing telescopes aren't needed for catching sight, Brits have a much better chance of glimpsing them from what's known as a dark sky area. These are areas with minimal light pollution, which obscures light particles from stars, mean far more is visible. The UK has several designated 'dark sky' areas, although any remote location far away from cities and towns would still be better. While the shower has been seen over London, this was through multiple exposures from advanced camera lenses rather than the naked eye. View pictures in App save up to 80% data. On a clear night, April 22, 2020, the London Millennium Footbridge sparkles under a canopy of stars. Official dark sky areas include Moore's Reserve in the South Downs, West Penwith in Cornwall, Cranborne Chase in Dorset, Exmoor National Park, the Yorkshire Dales and North York Moors, Northumberland and Tomintoul and Glenlivet in the Cairngorms. Eryri National Park (Snowdonia) and Gower National Landscape in Wales are also dark sky areas. It is advisable to allow your eyes approximately 15 minutes to adapt to the lighting conditions before spotting the meteor showers, which will be visible about two-thirds of the way up from the horizon, where the atmosphere is less dense. The origin point for the Quadrantids is located in the now-defunct constellation of Quadrans Muralis, which is the source of its name, and it is situated near the Plough, also known as the Big Dipper, in the sky. View pictures in App save up to 80% data. The map highlights regions in the UK that experience the highest and lowest levels of light pollution, which significantly impacts stargazing opportunities. The Royal Museum of Greenwich stated: "The Quadrantid meteor shower is one of the most powerful and reliable meteor showers annually, reaching a peak rate of 120 meteors per hour during clear nights. These meteors are fragments of debris that enter Earth's atmosphere at velocities reaching 70 kilometers per second, disintegrating and producing the luminous trails we refer to as meteors." "The Quadrantids are recognized for their brief but intense peak that occurs over a span of just a few hours. These meteors seem to originate from the constellation Boötes, close to the Big Dipper. In 2004, astronomer Peter Jenniskens proposed that the source of the Quadrantids might be the minor planet designated as 2003 EH1."

Artist concept highlighting the novel approach proposed by the 2025 NIAC awarded selection of SUPREME-QG: Space-Based Ultra-Precise Measurement of Quantum Gravity's Equivalence Principle Signature Selim ShahriarNorthwestern University, located in Evanston. Progress in physics has largely been driven by the development and verification of new theories that unify different fundamental forces of nature. For example, Maxwell revolutionized physics with his unified theory of electricity and magnetism, and the Standard Model of particle physics provides a consistent description of all fundamental forces (electromagnetic, strong, and weak) except for gravity. The major barrier to completing the quest for unification is that General Relativity (GR), the current theory of gravity, cannot be reconciled with QM. Theories of Quantum Gravity (TQG), which are yet untested, prescribe modifications of both GR and QM in a manner that makes them consistent with each other. Tests of TQG represent arguably the greatest challenge facing our understanding of the Universe. The most promising way to test TQG is to search for violation of the Equivalence Principle (EP), a fundamental tenet of GR which states that all objects experience the same acceleration in a gravitational field. Violation of EP is characterized by a nonzero Eotvos parameter, Eta, defined as the ratio of the relative acceleration to the mean acceleration experienced by two objects with different inertial masses in a gravitational field. EP violations at the level of Eta < 10^(-18) arise in many versions of TQG (e.g., string theory). The most precise test of the EP to date has been carried out under the space-borne MICROSCOPE experiment employing classical accelerometers, constraining the value of Eta to <1.5×10^(-15). We propose to investigate the use of a radically new method that leverages quantum entanglement to test the EP with extreme precision, at the level of Eta ~ 10^(-20), using a space-borne platform. This method is described in a recent paper by us (PRD 108, 024011, ’23). It makes use of simultaneous Schroedinger Cat (SC) state atom interferometers (AIs) with two isotopes of Rb. Consisting of N=10^6 atoms, the SC state, which is a maximally entangled quantum state generated via spin-squeezing of cold atoms in an optical cavity, acts as a single particle, in a superposition of two collective states, enhancing the sensitivity by a factor of ~root(N)=10^3. Such large-N SC states are difficult to create and have not been observed yet, let alone leveraged for precision metrology. In another recent paper, we described a novel protocol, namely the generalized echo squeezing protocol (GESP), to overcome the challenges of creating such a state (PRA 107, 032610, ’23). We will demonstrate the functionality of this method in a testbed to enable a follow-on space-borne mission capable of testing the EP at the level of Eta ~ 10^(-20). If EP violation is observed, the version of TQG that agrees most closely with the result would form the foundation for a complete theory governing the universe, including its birth: the Big Bang. A null result would force physicists to conceive an entirely new approach to addressing the irreconcilability of GR and QM, fundamentally altering the course of theoretical physics. Either outcome would represent one of the greatest developments in our quest for understanding nature. The SC-state AI (SCAI), also holds the promise of revolutionary improvements in the precision of gravitational cartography and inertial navigation, when configured for simultaneous accelerometry and rotation sensing. The sensitivity of such a sensor, for one second averaging time, would be ~0.9 femto-g for accelerometry, and ~0.5 pico-degree/hour for rotation sensing. This would represent an improvement by a factor of ~10^5 over the best conventional accelerometer, and a factor of ~10^4 over the best conventional gyroscopes. As such, the SCAI would find widespread usage in defense as well as non-defense sectors, including deep-space exploration, for inertial navigation. A space-borne SCAI would be able to carry out gravitational cartography with a resolution far greater than that achieved using the GRACE-FO satellites.

Science & Tech | The ambitious project would involve a space-based solar station generating power in the orbit and then transmitting the same to Earth. View pictures in App save up to 80% data. Please note: The image displayed above has been created using AI technology. Photo credit: (WION) China is embarking on yet another bold energy megaproject, following its announcement of the construction of the largest dam globally, this time venturing into space. A prominent Chinese scientist has referred to this initiative as "a Three Gorges Dam project in orbit." According to the South China Morning Post, scientist Long Lehao is considering the use of super heavy rockets to establish solar power stations beyond our planet. The visionary initiative aims to establish a solar power station in space that would harness solar energy in orbit and relay it back to Earth. These solar stations have the advantage of producing energy consistently, unaffected by the fluctuations of day and night. "We are currently engaged in this project, which holds as much importance as relocating the Three Gorges Dam to a geostationary orbit 36,000 km (22,370 miles) above the Earth. This is an extraordinary endeavor that we eagerly anticipate," stated Lehao, a rocket scientist and a member of the Chinese Academy of Engineering (CAE). The immense scale of the project has led specialists to draw parallels with the Three Gorges Dam in central China, recognized as the largest hydropower project globally. This monumental structure is located along the middle section of the Yangtze River, the longest river in China. When it becomes fully operational, the dam is expected to produce an annual power output of 100 billion kWh. "Picture a solar array stretching 1 kilometer wide positioned along the 36,000-kilometer geostationary orbit," Long remarked during a presentation at the Chinese Academy of Sciences (CAS) in October. A Chinese scientist has asserted that the solar energy harvested from a proposed megaproject each year could match the total energy output of all the oil reserves on Earth. He noted that implementing the solar system in outer space would necessitate the creation of super-heavy rockets. Long has suggested that the Long March-9 (CZ-9), a reusable heavy-lift rocket designed by his team, could be utilized to carry the bulky equipment into Earth's orbit.

The Exciting Mathematics of 2025 (Featuring Two Demonstrations of a Classic Greek Theorem)

2025-04-08 05:44:08

Say goodbye to the tetrahedron and welcome the generalized enneadecagon! Welcome to 2025! A lovely year, filled with excellent things. Obviously, we’re not talking about the state of the planet – that’s pretty terrible, all things considered. But the math? That is delectable. The spatial design of 2025 One of the most straightforward observations about the upcoming year is that 2025 is a perfect square. Specifically, it can be expressed as 45 multiplied by 45, indicating that if we were to create a large square with each side measuring 45 units, the overall area would amount to 2025 square units.  View pictures in App save up to 80% data. Feel free to verify the numbers for yourself if you're skeptical. Image credit: ©IFLScience That’s not all, though: because it’s an odd square, it’s also a centered octagonal number – which, much like with square numbers, is precisely what it sounds like: it means we can draw a perfect octagon using exactly 2025 pieces. Let's delve into something even more intricate: 2025 is classified as an enneadecagonal number (for those who aren't familiar with geometric terminology, that's a shape with 19 sides). However, there's a catch – it happens to be a negative enneadecagonal number, specifically the -15th one, which makes it quite impossible to visualize.  We are confident in its accuracy because every enneadecagonal number can be expressed using the following formula: Nm = m(17m - 15)/2 and plopping m = -15 into this recipe gives us 2025. The titles of 2025 Along with square, octagonal, and enneadecagonal, 2025 has a few pretty names. It’s a powerful number: an integer m such that if p|m, then p2|m. The reason for that is fairly simple – it’s 452, which is equal to (32)2×52 – or in other words, every prime factor of it turns up at least twice. It’s classified as a refactorable number, or tau number, indicating that it can be divided by the total count of its divisors. For instance, consider the number 18: it has six divisors, which are 1, 2, 3, 6, 9, and 18, and it can be evenly divided by six. In the same vein, the number 2025 possesses 15 divisors, with one of them being 15. To enumerate them all, the complete list of divisors for 2025 includes 1, 3, 5, 9, 15, 25, 27, 45, 75, 81, 135, 225, 405, 675, and 2025. Theorems from the year 2025 Let’s get onto the good stuff, shall we? We’ve already seen that 2025 is a perfect square, but dig a little deeper and we see some even prettier patterns. Forty-five, the number’s square root, is also a triangular number, and that means we can write it as a sum of consecutive numbers. Like this: 45 = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9. This indicates that  2025 = (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9)2,  which is nice for sure, but that’s not all. Thanks to Nicomachus, an ancient Greek follower of Pythagoras who lived between around 60 CE and 120 CE, we know that numbers that can be written like this – the squares of triangular numbers – also have another interesting property: they can be rewritten as the sum of the cubes of those same numbers. In other words, because  2025 = (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9)2, we are also aware that  2025 = 13 + 23 + 33 + 43 + 53 + 63 + 73 + 83 + 93. Isn't that awesome?! There are several methods to demonstrate this – one of the most elegant is through this proof that doesn't require any words: View pictures in App save up to 80% data. Pretty cool, right? Photo credit: Cmglee, CC BY-SA 3.0, sourced from Wikimedia Commons. An alternative approach involves utilizing the characteristics of square and cube numbers directly. In reality, it is this method that earns old Nicomachus his recognition, rather than the mere observation of the theorem. His namesake result takes a step back and, in a technical sense, states the following: ∀n∈N>0 : n3 = (n2 − n+1) + (n2 − n+3) + … + (n2 + n−1). That might look… well, like it’s written in another language, and it sort of is, but really it just means that any number n cubed can be written as the sum of n consecutive odd numbers beginning at (n2 − n+1). Like this:  1 等于 1 8 can be expressed as the sum of 3 and 5. 27 can be expressed as the sum of 7, 9, and 11. 64 can be expressed as the sum of the numbers 13, 15, 17, and 19. 125 = 21 + 23 + 25 + 27 + 29 and so forth. Now, written out like that, you can probably see a nice pattern already, right? If you sum up the first k cubed numbers, you’re going to get 13 + 23 + 33 + … + k3 = 1 + 3 + 5 + 7 + 9 + 11 + … + (k2 − k+1) + (k2 − k+3) + … + (k2 + k−1). Now, let's examine square numbers. They exhibit a similar pattern and can be expressed in the following manner: 1 等于 1 4 可以表示为 1 加 3。 9 = 1 + 2 + 6 16 can be expressed as the sum of the first four odd numbers: 1 + 3 + 5 + 7. 25 = 1 + 3 + 5 + 7 + 9 and so on – that is, the square of n is equal to the sum of the first n odd numbers.  But guess what? That sum we found before is precisely that – it’s the sum of the first (k2 + k)/2 odd numbers! In other words, 1 + 3 + 5 + 7 + 9 + 11 + … + (k2 − k+1) + (k2 − k+3) + … + (k2 + k−1) = ((k2 + k)/2)2. So there’s just one thing left to prove, and that’s that (k2 + k)/2 is equal to the sum of the first k natural numbers. Luckily, that’s pretty easy – it’s the definition of a triangular number (or, if you prefer, you can do it visually:  View pictures in App save up to 80% data. The shaded area representing the triangular number is equal to half of the area of the n x (n+1) rectangle. Image credit: ©IFLScience However you prove it, though, the math doesn’t lie: the sum of (n cubes) equals the (sum of n) squared. And now is as good a time as any to rave about this nice little result, since 2025 proves it perfectly. Happy New Year!

'Abundant venom levels!' Alert raised as a newly identified 'big boy' funnel-web spider capable of causing death within 15 minutes is found.

2025-03-15 11:36:34

Atrax christenseni has officially been recognized as one of the most venomous spider species in the world. Australian scientists have discovered a new species of funnel-web spider that is almost double the size of its nearest relative and has the ability to inject "large quantities of venom." Dubbed the 'Big Boy', the deadly arachnid can grow up to 9cm in length and possesses longer fangs than the common Sydney funnel-web spider. The recently identified species, known as Atrax christenseni, was found in the vicinity of Newcastle, approximately 170 kilometers north of Sydney, and has been recognized as one of the most venomous spiders in the world. Researchers indicate that its more substantial venom glands and elongated fangs might be capable of piercing through protective gloves, and similar to its relative from Sydney, it can be lethal within 15 minutes if antivenom is not administered. View pictures in App save up to 80% data. Arachnologist Kane Christensen first encountered the spider in 2018. In 2018, spider specialist Kane Christensen made his initial discovery of these extraordinary arachnids while employed at the Australian Reptile Park. Upon informing the Australian Museum in Sydney, researchers verified that it was a previously undiscovered species, which they subsequently named to honor Christensen. "It's hard to believe. Having a spider that I'm deeply passionate about named in my honor feels like a dream realized. It's truly thrilling," Christensen shared with 9News. The spider can reach a body length of up to 4.5cm and possesses venom glands that are considerably larger than those of typical funnel-web spiders in Sydney. Christensen remarked, "The size of this male specimen is simply... astonishing." RECENT UPDATES View pictures in App save up to 80% data. Specialists indicated that the spider might be spotted roaming around a garage or bedroom. After conducting thorough DNA analysis, researchers have validated the existence of three separate species of funnel-web spiders in the area. In addition to the recently uncovered Newcastle funnel-web, scientists have also recognized the 'traditional' Sydney funnel-web (Atrax robustus) and the Southern Sydney funnel-web (Atrax montanus). The Newcastle species has been located within a 25km radius of the Newcastle region and is not expected to migrate southward to Sydney. Professor Kristofer Helgen, head of the Australian Museum Research Institute, described it as "a remarkable milestone in the study of spider biology." DNA analysis has shown that the Newcastle funnel-web spider and the Sydney species diverged from a common ancestor approximately 17 million years ago. Although this spider possesses a highly toxic venom, specialists have verified that the current antivenom is still effective against this newly identified species. View pictures in App save up to 80% data. Kane Christensen referred to the finding as 'incredible.' Since the development of antivenom in the 1980s, there have been no recorded fatalities from funnel-web spider bites in Australia. Nonetheless, Christensen cautioned those who find themselves in close proximity to the spider. "I definitely wouldn't advise getting close to them; the amount of venom they produce is significant," he cautioned. Professor Geoff Isbister, who heads the Clinical Toxicology department at Calvary Mater Hospital in Newcastle, pointed out that the spider's increased size might result in a higher quantity of venom with each bite. He added that the antivenom is "extremely effective if administered promptly, ideally within one to two hours following the bite." Newcastle funnel-web spiders typically reside in garages, bedrooms, and various parts of homes, often entering during the night. The male spiders are especially active from November to April, as they venture out after dark in search of potential mates.

The "Faint Young Sun Paradox" That Confounded Carl Sagan

2025-03-14 22:29:36

If the Sun was cooler billions of years ago, why didn't Earth become frozen? View pictures in App save up to 80% data. In its early years, the Sun had a lower temperature. Photo credit: RealCG Animation Studio/Shutterstock.com In the past hundred years, our comprehension of stellar evolution has advanced significantly. Through the exploration of the universe, we have developed a solid theoretical framework that outlines the transformations stars undergo throughout their existence. But looking at our own Sun, a G-type star on its main sequence fusing hydrogen to helium, and comparing it to our best models, we are left with a little conundrum. In the early life of the Sun, when the Earth was newly formed, scientists believe that the Sun gave off less energy than it does today. "According to standard solar models, when nuclear fusion ignited in the core of the Sun at the time of its arrival on what is called the zero-age main sequence (ZAMS) 4.57 Ga (1 Ga = 109 years ago), the bolometric luminosity of the Sun (the solar luminosity integrated over all wavelengths) was about 30 percent lower as compared to the present epoch," a paper on the topic explains. Although this might not initially seem like an issue, it has confounded scientists for many years. The reason? If the Sun's brightness were the sole factor, we would anticipate that Earth's climate during that ancient period would have been extremely frigid.  "We see that the global temperature of Earth dropped below the freezing point of seawater less than 2.3 aeons ago (1 aeon is 109 years); 4.0 to 4.5 aeons ago global temperatures were about 2,63OK," Carl Sagan and George Mullen wrote, turning their attention to the topic in 1972. "Had we used 50 percent for ΔL, the freezing point of seawater would have been reached about 1.4 aeons ago, and temperatures 4.0 to 4.5 aeons ago would have been about 245°K. Because of albedo instabilities [...] it is unlikely that extensive liquid water could have existed anywhere on Earth with such global mean temperatures." And yet, evidence seen around the globe in ancient rock show that the Earth had abundant water flowing 3.2 aeons ago. As well as this, Sagan and Mullen point out, we have algae fossils dating back to around the same time "which would be very difficult to imagine on a frozen Earth." In short, Earth should have been a snowball billions of years ago, looking at the Sun's luminosity, and yet it wasn't. Over the decades, scientists have proposed potential explanations for the paradox.  "An extreme atmospheric greenhouse effect, an initially more massive Sun, release of heat acquired during the accretion process of protoplanetary material, and radioactivity of the early Earth material have been proposed as reservoirs or traps for heat," one study explains. According to that study, the Moon could have played a role in heating the Earth during that early epoch. As the Moon was closer (yes, the Moon is slowly drifting away) back then, it could have heated the Earth through tidal forces. "The paper further explains that tidal heating, as a source of geothermal energy, may have contributed to maintaining elevated mantle temperatures by facilitating the circulation of hydrothermal fluids within the early Earth's crust."  Stronger solar winds in the Sun's early days, heating through carbon dioxide, or high concentrations of ammonia gas (as suggested by Sagan) are favored possibilities, or a combination of these effects.  To add to this puzzle, looking at Mars, it too appears to have had liquid water on its surface around 3.6 billion years ago, and perhaps stretching as far back as 4.45 billion years ago. This could be the result of carbon dioxide buildup or methane outgassing, but we might not be able to solve the Mars paradox without getting a closer look at the planet's rocks. For this, we may now have to wait until 2040. While we may hone in on the exact cause of the faint young sun paradox on Earth, Mars's puzzle may take another 15 years at least.

Male Japanese rice fish can mate as many as 27 times in a single day, while females typically engage in mating just once.

2025-04-02 16:16:51

The scientists observed a marked decline in sperm quantity following the tenth mating. View pictures in App save up to 80% data. On average the males managed 19 matings in a single day.  Image Credit: © WATANABE Hitoshi 渡辺仁, via iNaturalist CC BY 4.0 The animal kingdom can get pretty weird when it comes to sex and relationships. Different creatures have evolved all sorts of methods to pass on their genes to the next generation and beat out competitors in the process. For the Japanese rice fish, researchers have discovered that it's all about how many times a day the males are getting freaky, which could be as many as 27.  Japanese rice fish – also known as medaka (Oryzias latipes) – are a small, unassuming species that live wild in the marshlands and rice fields of Japan. They are externally fertilizing fish, which means they release sperm or eggs into the water column, where they fertilize.  “Medaka are among the fish that spawn, where fertilization occurs after the eggs and sperm are released in water. As these gametes are difficult to collect, the number of sperm released and the fertilization rate during successive matings had remained a mystery,” study co-author Dr Yuki Kondo explained in a statement. “Our research group previously developed an accurate method for measuring the sperm count of medaka, which is why we were able to successfully conduct this experiment.” During the breeding season, which spans from April to September, female fish typically spawn once each day, while males can ejaculate several times within a single day. In the research conducted, a male fish was paired with a female until mating took place or until a duration of 20 minutes elapsed. Following this, the male was moved to a different tank containing a new female. This procedure was repeated until the males were unable to successfully mate with three consecutive females.  The frequency of mating among the males showed significant variation, with some mating as few as 4 times in a single day and others reaching up to 27 times. On average, the males managed to mate approximately 19 times each day. The researchers focused primarily on the quantity and quality of sperm produced after each mating session. In the initial three matings, the fish expelled over 50 percent of their daily sperm, resulting in a fertilization rate close to 100 percent for the eggs. However, as the number of matings increased, a marked decline in fertilization rates was observed after the 10th mating. In certain later matings, fertilization was completely absent. This indicates that females might be jeopardizing their eggs by mating with males who have already engaged in numerous other matings within a brief timeframe.   “This study represents the first quantitative analysis of the daily mating capacity of male medaka, detailing the amount of sperm expelled during each mating event, the fertilization rates achieved, and the mating behaviors exhibited by both males and females,” stated co-author Professor Satoshi Awata. “Our findings offer valuable perspectives on the connection between gamete production costs and the dynamics of sexual selection.” The paper is published in the journal Royal Society Open Science.

Initiated on October 18, 2018, BepiColombo stands as the second and most intricate mission ever designed to orbit the planet Mercury. View pictures in App save up to 80% data. The enigmatic north pole of Mercury unveiled by M-CAM 1 (ESA) The European Space Agency’s BepiColombo‘s sixth and final Mercury flyby, executed on January 8, 2025, successfully set the stage for its planned orbit insertion in late 2026. The ESA/JAXA mission skimmed just a few hundred kilometers above Mercury’s north pole, capturing close-up images revealing potentially icy, permanently shadowed craters and the expansive sunlit northern plains. At 06:59 CET, BepiColombo soared to an altitude of just 295 km above the cold, shadowy night side of Mercury. Approximately seven minutes later, it flew directly over the planet's north pole, offering clear perspectives of Mercury's sunlit northern hemisphere. Following its passage through Mercury’s shadow, BepiColombo’s monitoring camera 1 (M-CAM 1) captured the initial detailed images of Mercury’s surface. As it soared over the ‘terminator’ – the dividing line between daylight and darkness – the spacecraft seized a rare chance to look directly into the perpetually shadowed craters located at the planet's northern pole.

This latest flyby occurred just over a month after the last one,” remarks Frank Budnik, the Flight Dynamics Manager for BepiColombo. “According to our initial evaluation, the operation went smoothly and without any issues.” “Although the primary mission phase of BepiColombo is still two years away, the six flybys conducted around Mercury have already provided us with critical insights into this lesser-known planet. In the coming weeks, the BepiColombo team will diligently analyze the data from this flyby to uncover as many of Mercury's secrets as possible,” says Geraint Jones, the Project Scientist for BepiColombo at ESA. Initiated on October 18, 2018, BepiColombo stands as the second and most intricate mission ever designed to orbit the planet Mercury. Close to the Sun and more difficult for an orbiter to reach than Saturn, this small desert world is the least explored planet of the inner Solar System. Learning more about Mercury will shed light on the history of the entire Solar System. Equipped with advanced scientific tools, the mission aims to unravel several puzzling mysteries, including: What accounts for the presence of ice in the polar craters of this searing planet? What is the reason behind Mercury's magnetic field? And what could be the origin of the enigmatic 'hollows' found on its surface?

Archaeologists recover a 2,600-year-old shipwreck near the shores of Spain | Global | Headlines

2025-04-01 13:44:31

View pictures in App save up to 80% data. After more than three decades since its initial discovery, archaeologists have unearthed a shipwreck off the coast of Spain that dates back 2,600 years. The Mazarrón II went down around 600 B.C.E and was quickly covered by sand, which played a significant role in preserving it out of sight for many centuries. In a remarkable achievement, researchers successfully brought the shipwreck back to the surface from its underwater resting place between September and November 2024. While conducting the extraction, researchers uncovered new materials such as pieces of rope and ceramic fragments. The preservation of these fragile items offers a rare chance for advancement in archaeological studies. Step by step, a group of 14 experts, directed by Carlos de Juan from the University of Valencia, meticulously moved the Phoenician ship onto dry land for further study and preservation. Now, those fragments are going to a lab at the Museum of Underwater Archaeology in Cartagena for conservation and reconstruction.  Scientists are optimistic that the remains will provide fresh insights into the Phoenician civilization. Carlos de Juan, the director of the excavation project, told El Cronista: “It has been delicate work, but mechanical. Slow, but equivalent to what the team had already done before in other scenarios of extracting archaeological remains. "The vessel now resembles a cake in texture: it remains stable when horizontal but falls apart with even a slight tilt." Divers initially located The Mazarrón II in 1994 in the waters of Murcia, Spain’s Ministry of Culture revealed. It was one of two wrecks found near the town of Mazarrón, which they have both been named after. The vessel has a length of 8.10 meters and a maximum width of 2.25 meters. The wreck had been covered by a protective metal box, however, a group of experts found that the metal box was sinking and threatened to crush the shipwreck. In the summer of 2023, archaeologists devised a strategy to recover the shipwreck from the ocean floor. They dedicated 560 hours to diving at the site, meticulously creating detailed diagrams of the ship's numerous fractures. Currently, the team is focused on rehabilitating the artifacts and safeguarding them within the National Museum of Underwater Archeology. The University of Valencia stated: “This dedicated center will carry on the efforts of restoration and research, guaranteeing the conservation and examination of this invaluable historical accomplishment.”

According to MIT, miniature wireless 'antennas' have the potential to facilitate high-resolution biosensing.

View pictures in App save up to 80% data. An illustration of the micrometer-scale "antennas" designed for enhanced biosensing capabilities [Image credit: Marta Airaghi and Benoit Desbiolles/MIT] Researchers at MIT have recently unveiled a new method for achieving high-resolution biosensing without the need for wires. In a paper published Dec. 20, 2024 in the journal Science Advances, the researchers described organic electro-scattering antennas (OCEANs) for wireless, light-based probing of cellular electrical signals. They said the “antennas” could provide micrometer spatial resolution, potentially from thousands of sites, during in vitro studies. The following phase, however, involves evaluating their optical sensing arrays using real cell cultures cultivated on the surface. “Being able to record the electrical activity of cells with high throughput and high resolution remains a real problem. We need to try some innovative ideas and alternate approaches,”  Benoît Desbiolles, a former postdoc in the MIT Media Lab and lead author of a paper on the devices, said in an MIT news release. According to a news release from MIT, traditional devices that capture electrical signals in cell cultures and other liquid settings have been constrained by the use of wires, limiting the deployment of sensors. In contrast, researchers at MIT have developed antennas that are merely 1 micrometer wide—about one-hundredth the diameter of a human hair. These innovative antennas leverage the properties of the polymer poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS), which can either attract or repel positive ions from the liquid environment in response to nearby electrical activity. This interaction leads to alterations in the polymer's chemical configuration and electronic structure, which in turn modifies its refractive index and affects how it scatters light. Illuminating the antenna alters the light intensity in relation to the electrical signal produced by the liquid. According to researchers from MIT, this allows scientists to utilize an optical microscope to collect the scattered light emitted by the numerous antennas in the array, enabling them to gauge electrical signals for enhanced biosensing resolution. The arrays were created by researchers at the MIT.nano facilities. They began with a glass base and applied layers of conductive and insulating materials, ensuring that each layer remained optically transparent. Next, they employed a focused ion beam to etch hundreds of nanoscale holes into the upper layers. Desbiolles explained, "This device functions similarly to a pen, allowing you to engrave any design with a resolution of 10 nanometers." The scientists placed their chip into a solution rich in the precursor materials needed for the polymer. By applying an electric current to the solution, they were able to draw the precursor substances into the small pores of the chip, allowing the mushroom-shaped antennas to form and develop from the base upwards. Desbiolles and his team believe that this method could potentially allow for the production of millions of antennas. According to Desbiolles, "This method can be readily modified to ensure full scalability. The only constraint is the number of antennas we can capture images of simultaneously." The research team developed high-resolution biosensing arrays that allow for cell cultures to be placed directly on their surface, enabling analysis under an optical microscope. They fine-tuned the size of the antennas and modified various parameters, resulting in a heightened sensitivity that can detect signals with voltages as low as 2.5 mV during simulated experiments. This voltage is merely a tiny portion of what is generated by neurons for their communication processes. “Bioelectricity plays a crucial role in how cells operate and in various biological processes. Nevertheless, capturing these electrical signals with precision has proven to be difficult,” stated Deblina Sarkar, the lead author of the study, who is also an assistant professor at the Media Lab and MIT Center for Neurobiological Engineering, as well as the director of the Nano-Cybernetic Biotrek Lab. “The organic electro-scattering antennas (OCEANs) we have created allow for the wireless capture of electrical signals with micrometer-level spatial precision from thousands of locations at once. This technology opens up remarkable possibilities for exploring essential biological processes and disrupted signaling in disease conditions, as well as for evaluating the impact of various therapeutics to facilitate innovative treatment options.”

Adobe Stock THURSDAY, Jan. 9, 2025 (HealthDay News) -- Preexisting neuroanatomical variability is associated with substance use initiation in children younger than 15 years, according to a study published online Dec. 30 in JAMA Network Open. Dr. Alex P. Miller and his team from Indiana University School of Medicine in Indianapolis conducted a study to investigate the neuroanatomical characteristics linked to early initiation of substance use. They aimed to determine whether these associations indicated preexisting vulnerabilities. The research utilized data collected over a three-year period, starting from baseline, and involved a cohort of 9,804 children. Among them, 35.3 percent reported having begun using substances before reaching the age of 15. The researchers found a link between the start of any substance or alcohol use and a thinner cortex in the prefrontal areas (such as the rostral middle frontal gyrus, β = –0.03). In contrast, they observed a thicker cortex in other brain lobes, as well as increased volumes in the globus pallidus and hippocampus, along with enhanced overall brain structure indices (for example, a larger whole brain volume, β = 0.05). Additionally, cannabis use initiation was associated with a reduced volume in the right caudate (β = –0.03). Most of these associations, including the thinner prefrontal cortex and the larger whole brain volume, were noted to precede the initiation in further analyses that focused on postbaseline initiation. "The authors suggest that a deeper comprehension of the connections between brain structure and substance use could reveal predispositional risk factors, offering valuable insights into the early origins of substance use disorders and the clinical mechanisms that lead to various negative health outcomes associated with substance involvement."

And the ways in which they could be affecting your surroundings. AUSTIN, Texas, Jan. 10, 2025 /PRNewswire/ -- What is a portal, and do they exist beyond science fiction? Energy Freedom Technologies conducts research and experiments with portals and shares that a portal is an energetic gateway that can move between and sometimes through dimensions. "Portals allow energies to come into and/or out of space," said Energy Freedom Technologies founder Nicole Cobb Edwards. "For example, a one-way portal pulling energy out of a space may be sucking the health and happiness out of the environment and you may even notice physical items go missing like remotes, keys, and other personal objects. There are also portals that are one-way in the other direction meaning they are inputting energy into a space. Sometimes these portals are inputting confusion energy, and it is also very common for them to bring in entities. The most common portals I experience are two-way portals that have energies coming in and out. Most of these portals are not conductive to a harmonious environment so I find it supportive to acknowledge them and often close portals for clients that prefer more harmony in their space." Subtle energies accumulated in some areas cause an anomaly in the space-time continuum, opening portals into other dimensions. Sometimes the gateway into another dimension results in the appearance of interesting creatures and forces. In the book Merging Dimensions, authors Tom Dongo and Linda Bradshaw describe research conducted on the Bradshaw Ranch in Sedona, Arizona. Detailed studies verified a series of interesting events on the Ranch and throughout Sedona, continuing over many years. Often, portals can create more subtle disturbances in the environment. Dr. Claude Swanson's Synchronized Universe Model explains the science of how this may happen. Parallel dimensions differ from our current reality by a shift of frequency and phase.  They can be co-located with us and yet not detected, until something causes a shift in the fundamental frequency of our "reality" so it matches theirs. Subtle energy, which accumulates in certain spaces and environments, has precisely this effect. In doing so it opens portals into parallel dimensions. Do you or a loved one avoid a certain area of your home or property? Is there a room in your home that feels draining and heavy? Is there a room in your home that feels highly energized, and it's challenging to relax or sleep in there? Have you noticed things go missing in a specific room or area on your property? If you answered yes to any of these questions, it's possible that there is a portal in your space. Energy Freedom Technologies offers property harmonization services to create more balance and harmony in your environment. Energy Freedom Technologies is a company focused on developing innovative solutions in the field of renewable energy. Their mission is to empower individuals and communities by providing access to sustainable energy sources. By leveraging cutting-edge technology and research, they aim to create efficient, cost-effective systems that promote energy independence and reduce reliance on fossil fuels. With a commitment to environmental sustainability, Energy Freedom Technologies strives to contribute to a cleaner, greener future for all.

A happiness specialist reveals a concerning pattern: 'A decline in the overall well-being of the youth.'

2025-03-29 21:31:10

View pictures in App save up to 80% data. Scatterplot ranks of WHR and HDI. Credit: PLOS ONE (2024). DOI: 10.1371/journal.pone.0305347 Economist David Blanchflower focuses on the topic of happiness. For over twenty years, the Bruce V. Rauner 1978 Professor has authored more than 30 research papers that uncover a consistent trend in how individuals generally perceive happiness and well-being throughout their lives. This pattern, which has been reproduced countless times by various researchers, is well-known for its representation on a U-shaped graph. "Essentially, our research indicated that individuals experience their lowest levels of happiness during middle age. Happiness seems to be prevalent in youth and again in later years, creating a U-shaped curve," explains Blanchflower, an expert in labor economics who was part of the Monetary Policy Committee at the Bank of England from 2006 to 2009. Recently, Blanchflower and his team have observed a concerning shift. The left side of the U—symbolizing the youth—is no longer rising. What’s behind this change? Young individuals across the globe have been expressing higher levels of dissatisfaction. Blanchflower suggests that the rise of smartphones and social media could be a significant contributing factor. Blanchflower states that although it has only come to light recently, the change in the happiness trend actually started over ten years ago. "The U-shaped curve was once considered a key concept in social science, but that has changed," he explains. "Our findings indicate that beginning in 2013, this U-shaped trend began to fade away. It's not that the previous observations were incorrect; rather, they evolved. We are now witnessing a global decline in the well-being of young people, particularly among young women." What raises concerns about smartphones and social media? Since the launch of the first iPhone in 2007, the prevalence of these technologies has skyrocketed, significantly altering how individuals, particularly children, interact socially. Blanchflower notes, "When children dedicate time to smartphones, they miss out on face-to-face interactions and the activities we, as kids, enjoyed." He adds, "Neuroscientists indicate that interpersonal interactions help our brains create crucial connections that influence social and emotional development." He contends that the hours children dedicate to smartphones could have been better utilized in interacting with peers and fostering their cognitive development. Supporting this claim, a recent study by the Centers for Disease Control and Prevention revealed a concerning correlation: increased social media usage among high school students is linked to a higher likelihood of experiencing bullying and cyberbullying. And Blanchflower himself recently published a paper in the International Journal of Wellbeing on how the experience of childhood traumas, including bullying, can have lifelong negative effects. "According to Blanchflower, the repercussions of bullying can last for decades, sometimes even up to 50 years. This suggests that cyberbullying could lead to a range of detrimental outcomes. It affects various aspects of life, including educational achievements, the quality of personal relationships, and even one's earning potential." Still, when they first noticed the change in the U-shaped graph, Blanchflower and his colleagues thought the trend might be related to major events, such as the COVID-19 pandemic or the financial crisis of 2008. But their deep dive into micro-data from major surveys in the U.S., Europe, and the U.K., among others, recently published in the journal PLOS ONE, showed that these events had only a short-term negative impact on reported well-being. According to Blanchflower, these temporary crises generated disturbances that obscured the longer-term patterns in the data. "We all acknowledged that COVID was a serious issue. However, what we overlooked was that COVID merely accelerated an ongoing trend that had been developing. Now, we find ourselves trying to make up for lost time as we were diverted by the pandemic and failed to recognize this persistent trend." A noticeable decrease in the happiness and overall well-being of young people has been reported across various nations, such as the U.K., U.S., Canada, Australia, New Zealand, Scandinavian countries, the Netherlands, France, Germany, and Italy. Over the last year, Blanchflower has collaborated extensively with the United Nations to analyze global trends in mental health. He is presently engaged in the development of multiple working papers commissioned by the UN, which examine trends in well-being among youth globally. He has already finalized studies focusing on the U.S., the U.K., Europe, Africa, and Latin America. According to him, well-being has notably decreased, particularly among young individuals who are internet users. (These papers can be accessed on Blanchflower's website.) Certain K-12 schools have begun restricting students' use of smartphones, and Australia has recently implemented a ban on social media platforms for individuals under 16 years old. Blanchflower emphasizes that grasping the reasons behind the trend is essential for discovering solutions to reverse it. "We must avoid creating a lost generation," he states. He is in the process of coordinating a significant conference scheduled for October, in collaboration with the Human Development Report Office of the United Nations Development Programme. This event aims to unite experts, global policymakers, and higher education leaders to exchange research findings and effective strategies for tackling the ongoing crisis. The symposium is set to take place at Dartmouth, where President Sian Leah Beilock has prioritized mental health significantly. He expresses, "There is an increasing agreement that this is occurring. The discussion revolves around the causes, the extent of its spread, and the appropriate responses. This is where experts will convene to deliberate, and we will examine effective strategies from across the globe." More information: David G.

A prominent nose, striking blue eyes, and golden hair: The visage of King D. Dinis unveiled 700 years posthumously.

2025-03-18 23:36:36

View pictures in App save up to 80% data. Seven hundred years after his passing, the visage of King D. Dinis, Portugal's sixth monarch, was unveiled following comprehensive 3D facial reconstruction efforts. This facial analysis was conducted at the FaceLab of Liverpool John Moores University, with scientific oversight provided by anthropologist Eugénia Cunha from the University of Coimbra. The initiative commenced in 2016 with efforts to restore the tomb of D. Dinis. Nevertheless, it wasn't until 2023 that the crucial decision to open the tomb and conduct DNA analysis was made. D. Dinis’s face, at the time of his death, revealed an elderly man  64 years of age. Eugénia Cunha explains, "The findings we have were based on robust scientific data derived from a remarkably well-preserved skeleton that retains all of its facial bones." Cunha further describes the king as having “an elongated nose” and “a chin that is somewhat receding,” along with “blue eyes” that might have a hint of green blended in. D. Dinis would have stood  “between 1.65 and 1.68 meters” the scientist also reveals, noting that she had a “population affinity 71% European”. Miss Cunha noted that “he had all of his teeth at the time of death, with only one cavity,” highlighting that he was “an adult with remarkable resilience” and “quite sturdy.” "While some individuals did live to advanced ages, being 63 years old 700 years ago would be akin to being 90 or older in today's context," the scientist elaborates, adding that such longevity would likely be attributed to "proper nutrition" and their status within "an elite group." "Historical accounts suggest that the king was likely bedridden prior to his death, which could explain why he appeared gaunter in the face," she observes. Eugénia Cunha also disclosed that this marks “the first portrait of a Portuguese king to be scientifically validated.” “The appearance of this face is backed by scientific evidence. It wasn't the creativity of an artist that shaped the image of D. Dinis; rather, it was his skull and genetic makeup that revealed his true likeness,” emphasizes the anthropologist. The scientist further clarified that DNA analysis was conducted using the root of a tooth. “Afterward, we replaced the crown. We only compromised the root,” she emphasized, noting that they were not “damaging a femur or extracting teeth.” D. Dinis was responsible for one of the longest reigns in Portugal’s history  between the years 1279 and 1325. He was also known as the Farmer or Poet-King. His likeness will be unveiled to the nation in a touring exhibition set to launch in April 2025.

Experts indicate the age at which you're most inclined to form lasting friendships.

2025-04-07 00:11:43

Researchers have provided insights into why friendships formed during this period tend to endure for a significant length of time. View pictures in App save up to 80% data. I think we can all acknowledge that having friends is incredibly valuable. Yes, family is also important, but some studies have suggested that it is friendships that make more of a positive impact on your life - lifespan in particular. For example, a 2005 study in Australia found that people who had more friends than other participants tended to outlive those with fewer by 22 percent, Inc. reported last year. A separate study revealed that those with strong social ties had a 50 percent better chance of survival. View pictures in App save up to 80% data. Research indicates that individuals with robust social connections tend to have a longer lifespan (Getty Stock Image) As you age, you begin to realize that friendships can be transient; however, there are a handful of individuals who will remain your companions for a lifetime. According to experts, it ultimately boils down to timing. Research has shown that most people will at least maintain adolescent friendships into adulthood, reports The i In fact, a recent study conducted by the newspaper found that 83 percent of Brits over the age of 30 are still friends with people they befriended at school or college. Adolescence is typically characterized as the period ranging from ages 10 to 24. View pictures in App save up to 80% data. Studies indicate that friendships formed during teenage years tend to endure throughout a person's life (Getty Stock Image). It seems that there are compelling reasons why the friendships you build during that period are more likely to endure over the course of your life. Experts have described this moment as a 'pivotal time'. Sarah-Jayne Blakemore, a Professor of Cognitive Neuroscience at Cambridge University, stated: "Adolescence represents a crucial phase for forming friendships, and the bonds created during this period can last for many years." "It is a period of our lives in which we undergo large changes in our sense of self, and particularly our ‘social self’ - the way we depict ourselves to other people. This includes what peer group we want to be part of and our social relationships." View pictures in App save up to 80% data. Certain individuals maintain lifelong friendships (Getty Stock Image) The bonds of friendship established between the ages of 10 and 24 are strengthened because 'the brain is designed to prioritize new experiences' during this developmental phase. Many of these experiences will be linked to the friends we shared them with, making them deeply embedded in our memories. It is also proposed that the friends you make during that period play a significant role in shaping who you grow into as an adult. Blakemore stated, "During adolescence, the brain exhibits a high degree of plasticity and adaptability, especially in areas associated with social functions." "This indicates that your social surroundings, including the individuals near you and your relationships with peers, could significantly influence the growth and development of your brain."

A supermassive black hole has been observed at a distance of 12.9 billion light-years from our planet, and it is emitting a powerful beam of energy directed straight towards us.

2025-03-18 01:17:31

The recently identified "blazar," boasting a mass equivalent to 700 million suns, is the most ancient example of its type ever observed, altering our understanding of the early universe. View pictures in App save up to 80% data. Blazars are enormous black holes that emit powerful energy jets aimed straight at our planet. Astronomers have identified a supermassive black hole that is emitting an enormous energy beam directed straight at Earth. This colossal entity, weighing approximately 700 million times that of our sun, is targeting us from a galaxy dating back to the early universe, around 800 million years post-Big Bang. This discovery marks it as the farthest "blazar" ever observed. Some supermassive black holes, known as quasars, are so massive they can superheat the material doom-spiraling within their accretion disk to hundreds of thousands of degrees, at which point they emit huge amounts of electromagnetic radiation. The quasars' immense magnetic fields can sculpt this energy into twin jets that shoot out perpendicularly to accretion disks and extend well beyond their host galaxies. By chance, some of these quasars point one of their twin jets directly at Earth, creating radio bright spots that pulse as these black holes consume matter. These black holes are known as blazars. In the new study, published Dec. 18, 2024, in The Astrophysical Journal Letters, researchers discovered a new blazar, dubbed J0410−0139, using data from multiple telescopes, including the Atacama Large Millimeter Array, the Magellan telescopes and the European Southern Observatory's Very Large Telescope — all located in Chile — and NASA's Chandra observatory in Earth-orbit. Radio emissions from this blazar have journeyed over 12.9 billion light-years to arrive at our observation point, setting a new benchmark for this category of cosmic entities. The astonishing age of this luminous giant may provide scientists with insights into the formation of the earliest supermassive black holes and the subsequent evolution of these galactic cores. View pictures in App save up to 80% data. If they were located much nearer to us, blazars would shine as some of the most luminous objects in the night sky. "The alignment of J0410−0139's jet with our line of sight allows astronomers to peer directly into the heart of this cosmic powerhouse," study co-author Emmanuel Momjian, an astronomer at the National Radio Astronomy Observatory in Virginia, said in a statement. "This blazar offers a unique laboratory to study the interplay between jets, black holes, and their environments during one of the universe’s most transformative epochs." The most ancient blazar discovered to date. Fewer than 3,000 blazars have been discovered to date, and most have been located much closer to Earth than J0410−0139. The previous record holder for the most distant blazar was PSO J0309+27, which was discovered in 2020 and is around 12.8 billion light-years from Earth, making it around 100 million years younger than J0410−0139. When viewed in the context of the universe's vast age, this age gap appears negligible. Nevertheless, during those 100 million years, a supermassive black hole could potentially expand by several magnitudes, rendering this a noteworthy advancement. Finding one blazar at this distance hints that many other supermassive black holes existed at this point in cosmic history that either had no jets or beamed their radiation away from Earth, study lead author Eduardo Bañados, an astronomer at the Max Planck Institute for Astronomy in Germany, said in another statement. "Picture this: you come across a story about an individual who has struck it rich with a $100 million lottery win," Bañados remarked. "Considering how infrequent such a victory is, it’s clear that numerous other participants in that lottery didn’t walk away with such a massive prize. In the same vein, discovering one [quasar] with a jet aimed straight at us suggests that during that era of cosmic evolution, there were likely many more [quasars] whose jets were oriented away from our line of sight." The researchers will now hunt for more blazars from this time and are confident they will find some. "Where there is one, there's one hundred more [waiting to be found]," study co-author Silvia Belladitta, an astronomer at the Max Planck Institute for Astronomy, said in the statement.

Do Cows Actually Align Themselves With Earth's Electromagnetic Field?

2025-04-03 21:28:51

In 2008, scientists analyzed satellite imagery of grazing cows and discovered something rather surprising. View pictures in App save up to 80% data. Presenting the cow compass! Image source: Labellepatine/Shutterstock.com. In 2008, a group of researchers examining deer and cattle made an intriguing discovery. They observed that both species, whether grazing or at rest, tend to orient their bodies along the north-south axis. "Farmers and attentive nature and countryside observers know that most cattle and sheep, when grazing, face the same way," the team explained in their study. "The farmers’ wisdom and experience indicate that cattle face into the wind, whereas sheep face away from the wind; the animals expose the maximum body surface area to the sun when sun basking in cold but sunny times of the day." Although it is known that these animals often orient themselves in a specific direction while grazing, there has been limited scientific research into the reasons behind this behavior. In their investigation, the research team examined Google Earth satellite images capturing cows grazing globally, observed roe deer during their grazing and resting periods, and studied the body imprints left in the snow by red and roe deer. While they tried to consider elements like wind direction and the Sun's position in the sky, the researchers ultimately discovered that all these animals consistently aligned themselves along the magnetic north/south axis in statistically significant proportions. "The team stated, 'Since climatic elements such as wind, sunlight, or temperature do not seem to be prevalent directional influences that account for the widespread alignment, we deduce that the magnetic field is the sole and most probable factor responsible for the observed orientation.' They further added, 'Our examination of cattle in areas with naturally high positive and negative declinations offers compelling evidence supporting the notion that the Earth's magnetic field serves as the guiding signal.'" Though a strange result, it's not entirely out of the realms of possibility. Some animals, generally smaller than cows and deer, have been shown to have magnetoreception, or the ability to perceive the Earth's magnetic fields. In fact, it's surprisingly common, and particularly useful in migratory birds, likely aiding navigation.  In a subsequent investigation, the researchers suspected they had discovered indications that "orientation behavior" might be interfered with by the extremely low-frequency magnetic fields produced by high-voltage power lines. The team emphasized that the exact mechanism behind the orientation behavior remains unclear, although there are several hypotheses.  "For instance, the radical pair hypothesis proposes an intimate coupling of magnetic sensing with vision. According to this hypothesis, magnetic fields are perceived as visual patterns, which are dependent on both field direction and intensity," the team wrote in their study. "Thus, it is conceivable that the oscillations of the direction and intensity resulting from the [Earth's magnetic field] and [alternating magnetic field] interaction may blur magnetically modulated visual patterns and, in turn, compromise or disrupt magnetic compass orientation." Although the concept is intriguing, it might be premature to discard your compass in exchange for a more entertaining cow compass. A recent investigation involving 34 cows, which had powerful neodymium magnets affixed to their collars, revealed that these animals exhibited no noticeable directional preference, regardless of whether they were equipped with the magnets. Additionally, the study included 2,428 daytime observations of 659 resting cattle in Portugal, conducted at times excluding the hottest parts of the day, and concluded that the cows tended to prefer facing southeast. The team suggests that instead of having magnetoreception, the phenomenon is more related to the position of the Sun. They conclude that earlier research might have been biased due to the reliance on Google Earth images captured on clear, sunny days. "We found a significant correlation between the animal’s orientation and the direction of the sun, minimizing sun radiation on the animal’s body, similar to what was observed in horses," the team wrote in their discussion. "Indeed, if most views were made on cloudless sunny days, then the animals were possibly reducing their body exposure to the sun. We thus believe that the cattle’s reported south-north alignment observed in earlier studies could perhaps, at least in part, be attributed to thermoregulation, possibly overriding a magnetic alignment. Similar sun-reducing behaviour has been observed in springbok and in black wildebeest, and was demonstrated to be linked to thermoregulation in those studies." In summary, additional and more detailed research might be required to understand the reasons behind cows' tendency to align themselves while grazing and resting. For now, it's best not to rely on them as a substitute for a compass.

Inflatable Starshade for Habitable Exoplanets

2025-03-28 13:20:26

View pictures in App save up to 80% data. An artist's illustration showcasing the innovative strategy put forward by the 2025 NIAC-selected Inflatable Starshade for Earth-like Exoplanets project. John MatherNASA Goddard Space Flight Center We will design the first family of ISEE’s (Inflatable Starshade for Earthlike Exoplanets) with sizes from 35 to 100 m diameter. A starshade would enable any telescope to observe exoplanets, a top priority for astronomy worldwide. Compared with other starshade concepts, we aim for a lower mass, cost and complexity, while still providing high performance and science yield (>100 targets). Our starshades would be compatible with the 6 m diameter Habitable Worlds Observatory (HWO) now being planned, as well as the world’s largest telescope, the 39 m diameter European Extremely Large Telescope now being built in Chile, working as part of the HOEE, (Hybrid Observatory for Earthlike Exoplanets), and other future telescopes. We need to observe oxygen at visible wavelengths and ozone at UV. An ISEE, positioned between a target star and the telescope, would block the starlight without blocking the exoplanets. Starshades have perfect optical efficiency, they work with any telescope, and they can block the starlight much better than the requirement, for a star >1010 times brighter than the target. The alternative technology employs an almost flawless and highly stable space telescope, similar to HWO, equipped with an internal coronagraph designed to block starlight from obscuring the planet's image. Coronagraphs offer significant benefits, including their compact size, ease of testing, and immediate availability. Nonetheless, existing coronagraphs have yet to achieve the necessary contrast levels. Additionally, the development of an ultraviolet coronagraph remains unfeasible. If the stringent requirements for extreme picometer stability and optical precision of HWO and its coronagraph could be eased by integrating a starshade, it would allow for the construction of HWO at a significantly reduced cost and lower risk. Therefore, if ultraviolet observations of exoplanets are crucial, utilizing a 35 m starshade in conjunction with HWO emerges as the sole viable option. The HWO is set to be NASA's next major observatory and will feature a high-performance coronagraph designed for exoplanet observation. This decision has shifted the dynamics regarding the competing starshade technology. However, a starshade mission might still be deemed necessary under certain conditions: A. If the HWO and its coronagraph cannot be constructed and validated as needed; B. If the HWO needs to observe exoplanets in UV wavelengths, or if a 6 m HWO is insufficient to target the desired celestial bodies; C. If the HWO does not perform adequately after its launch, and servicing or instrument upgrades are not feasible; D. If HWO observations reveal that intriguing exoplanets are scarce, too far away, obscured by dense dust clouds surrounding their host stars, or cannot be fully analyzed with an upgraded HWO; or E. If HWO findings indicate that the next phase requires UV data, or a telescope significantly larger than what future HWO coronagraph enhancements can provide. An inflatable starshade presents a solution to the primary challenge associated with traditional starshade designs: their complex mechanical structures. Historically, starshades have not been launched, as they require precise shapes and edges, along with accurate propulsion and positioning. Previous designs utilizing discrete components can be enlarged to meet the dimensions needed for HWO (35-60 m) and HOEE (100 m), but they tend to be bulky, difficult to prototype, and thus incur significant costs and risks. Our target mass budget is set at 250 kg for the 35 m HWO variant, 650 kg for the 60 m option, and 1700 kg for the 100 m HOEE model. We plan to refine our concepts and create comprehensive designs along with finite element models to assess strength, stiffness, stability, and thermal performance. Additionally, we will establish small-scale testing facilities to address challenges such as the bonding of large, high-strength material sheets within inflatable configurations. Key deliverables will encompass mass and power budgets, evaluations of strength and stiffness, and laboratory testing of essential components. We will also revise the mission concepts for HWO and HOEE in light of the new starshade specifications.Depending on advancements in the HWO mission, starshades may be essential for enhancing our understanding of exoplanets. An inflatable starshade could facilitate their implementation.

Space Photo of the Week: Hubble's 23-Year Journey to Capture the Tilted Spiral Galaxy

2025-04-03 06:44:59

In this remarkable Hubble image, over two decades in the making, the dazzling spiral galaxy UGC 10043 unveils the mysteries behind its surprisingly large bulge. View pictures in App save up to 80% data. UGC 10043 is among the rare spiral galaxies observed from the edge perspective. What it is: Spiral galaxy UGC 10043 Where it is: 150 million light-years away in the constellation Serpens When it was shared: December 12, 2024 Why it's so special: This image of a spiral galaxy taken by the Hubble Space Telescope is a portrait more than two decades in the making. Similar to many full-color images of celestial bodies, this one is a composite made from images captured in various wavelengths of light. What distinguishes this particular image is that the data utilized for its creation was gathered during observation sessions in 2000 and 2023, spanning a remarkable 23 years. This long-term advantage of having a space telescope in orbit is evident: Hubble was launched aboard the space shuttle Discovery on April 24, 1990, and its extensive operational duration has allowed it to gather an immense wealth of data about the universe's many facets. But besides the prolonged methods used to create it, it's also an unusual image on its face. Spiral galaxies — which account for about 60% of all galaxies in the universe, according to the European Space Agency — are, by chance, typically seen face-on when viewed from the solar system. That’s why spiral galaxies are typically associated with vivid spiral arms, which can only be seen from a face-on vantage. However, UGC 10043 is viewed edge-on, with its rings seemingly flattened into a line. This unique angle gives astronomers the chance to see how spiral galaxies are structured in 3D. The image of UGC 10043 showcases distinct lanes of dust that would probably resemble spiral arms if the galaxy were viewed from a frontal perspective. In this view, these dust lanes obscure the combined light emitted by the stars that constitute the galaxy. Additionally, they harbor dark clouds that serve as regions for star formation. In the middle of the image lies a luminous bulge — the vibrant core of the galaxy. Every galaxy possesses a core, but the one in UGC 10043 is notably oversized. Researchers believe this may be a result of UGC 10043 merging with a nearby dwarf galaxy, which has provided an abundance of dust and gas, stimulating the formation of new stars. This collision might also account for the slight distortion in the galaxy's disk, which curves upwards on one side and downwards on the other.

Was the notorious Stanford Prison Experiment a complete fabrication?

2025-03-27 12:53:50

A French historian specializing in science has conducted an in-depth investigation into the real events behind the Stanford prison experiment, uncovering that the 'guards' were deliberately instructed to act with cruelty. His research has now been translated into English. View pictures in App save up to 80% data. Source: BBC/Stanford University. A recent translation of a 2018 work by French science historian Thibault Le Texier calls into question the assertions made by one of psychology's most renowned experiments. Exploring the Stanford Prison Experiment: Unraveling the Myth, published recently in English, documents serious limitations of the study – including that student “guards” were actually coached to dehumanise their “prisoners” – and asks how such a flawed experiment became so influential. A notorious 'cell' located in the basement of a university You’ve likely heard of the Stanford prison experiment. In 1971, 24 young male volunteers were randomly assigned to the roles of “inmates” and “guards” in a pretend prison in the basement of Stanford University’s psychology department. The circumstances escalated rapidly. By the second day, the volunteers assigned as guards had started to inflict psychological torment on the inmates. Deprived of clothing, blinded by hoods, bound by chains, and subjected to starvation and sleep deprivation, the inmates experienced severe psychological distress, with half of them experiencing nervous breakdowns. Consequently, by the sixth day, the experiment – originally intended to continue for two weeks – was abruptly terminated. The experiment was conducted by social psychologist Philip Zimbardo, who died last year at the age of 91. He argued that the transformation of seemingly normal people into cruel guards and passive prisoners was proof that social situations have the power to corrupt human behaviour. View pictures in App save up to 80% data. Inmates were required to don short smocks featuring identification numbers. Source: PirsonExp.org His sensational findings and the dramatic story of the experiment, illustrated with photos of uniformed guards in aviator shades and batons standing threateningly over cowering and hooded prisoners, made Zimbardo and his experiment famous. Since it was conducted over five decades ago, the lessons from the experiment have been applied to a burgeoning number of situations beyond prison. By 2007 Zimbardo used it to explain corporate fraud, military torture, cult behaviour and even genocide. A newly released English version of French scholar Thibault Le Texier’s 2018 work reveals a more intricate and concerning narrative surrounding the renowned study. It raises questions about Zimbardo’s credibility as the storyteller of his own findings. Critiques of the experiment are not a recent development; concerns regarding its methodology and Zimbardo's claim that situations can dominate our personalities have been raised since 1975. However, Le Texier's comprehensive findings, now accessible in English for the first time, provide an in-depth narrative of the events that transpired behind the scenes. Trained to be ruthless By utilizing archival materials, previously unreleased video recordings, transcripts, and in-depth interviews with those involved – such as the guards, inmates, and researchers – Le Texier constructs a detailed chronological narrative of the experiment's progression. Far from being swept up in the situation, archival sources show the guards’ brutality was rehearsed. Contrary to official accounts, before the experiment they were coached by the research team in how to create a psychologically hostile environment. Zimbardo provided the guards with a set of regulations to enforce, along with methods intended to dehumanize the inmates. As the experiment progressed, the staff motivated the guards to act aggressively and scolded those who showed too much compassion. View pictures in App save up to 80% data. The 'inmates' were confined to stark cells, with three individuals sharing each one. Source: PrisonExp.org In comparison, the inmates were not well-prepared. Many of them imagined their time behind bars would be filled with reading or watching television in their cells. Therefore, they were taken aback by the humiliations they faced, the lack of cigarettes and books, and other forms of entertainment, as well as the often capricious and shifting regulations. The reactions of the prisoners and guards to the circumstances varied significantly. While some guards embraced their responsibilities with fervor, others showed compassion towards the inmates, sneaking in snacks and cigarettes. One guard even decided to resign. Certain inmates chose to work together, while others stood firm against authority, and a few even staged a rebellion. One individual initiated a hunger strike. While many sought freedom, they quickly realized that, contrary to what they had been promised, leaving was not an option for them. Their release would only be granted in the event of a medical or psychiatric crisis. Le Texier discovered that only three prisoners were set free due to claims of emotional turmoil, and at least one of them had pretended to be in distress. The experiment was halted due to potential failure risks. Le Texier observed that by the sixth day, the guards were growing more ineffective as the remaining prisoners continued to resist. An unanticipated visit from a lawyer brought to light questions regarding the legality of detaining volunteers without their consent. Both of these elements contributed to the sudden conclusion of the experiment. A lasting hold on the shared awareness of society. According to Le Texier, several key elements have contributed to the lasting notoriety of Zimbardo's experiment, including his adeptness at engaging with the media, his talent for making complex ideas accessible to the public, the backing of his university, and the predominantly uncritical reception of his results. It continues to exert a powerful grip on the public imagination, largely through the promotional flair of its creator. View pictures in App save up to 80% data. In the Stanford prison experiment, the guards imposed numerous humiliations on the 'prisoners.' Source: PrisonExpo.org Le Texier’s book raises important questions about the cultural and political factors that shape research. For example, Zimbardo’s study was conducted during a period of intense anti-authoritarianism and against the backdrop of the 1971 Attica prison riot, the deadliest prison uprising in the United States. Le Texier's work offers valuable insights into science communication and highlights how media-savvy scientists can effectively create and share compelling narratives. The Stanford prison experiment may be downplayed or criticized in academic literature for its exaggerated assertions, yet it is improbable that it will fade from the collective consciousness of the public. According to Le Texier, the experiment has captured our shared awareness so strongly that, although its results may be inaccurate, it seems to convey a significant moral teaching. Zimbardo had a unique ability to address our deep-seated desire for solutions to the pressing issues of our era. While it may lack solid theoretical grounding and resemble a morality tale masquerading as scientific inquiry, the lasting notoriety of the Stanford prison experiment lies in its perceived insights into how ordinary individuals can descend into malevolence. This narrative continues to resonate, as it offers a compelling tale. Sale View pictures in App save up to 80% data.

In the Swiss Alps, the retreat of glaciers is revealing items that have been trapped in ice for hundreds of years. To date, archaeologists have unearthed artifacts from World War I, arrows dating back 1,300 years, and the preserved bodies of hikers who went missing long ago. In November of last year, a hiker named Sergio Veri stumbled upon what seemed to be a two-wheeled bamboo cart from the 20th century. However, archaeologists are still uncertain about its true nature. While strolling through the Splügen Pass in the Swiss Alps, close to the Switzerland-Italy border, Veri stumbled upon a peculiar device. The elevated route links Switzerland's Hinterrhein valley to Italy's Valle San Giacomo. He spotted the cart amidst the thawing Schwarzhorn Glacier. According to a social media update from the Canton of Graubünden, “The wagon-style design, featuring two wheels and crafted from bamboo sticks and laces, is estimated to be fairly recent, likely dating back to the 20th century.” The mysterious object has left specialists puzzled. Abandoned in the heights of the Alps, it is constructed from bamboo and secured with cords, a detail that stands out. However, bamboo is not indigenous to Switzerland and only made its way to Europe in the 17th and 18th centuries. Incorporating this material introduces an intriguing element that obscures the purpose and background of the object. The presence of bamboo suggests that the artisans had access to foreign resources. The Archaeological Service of Graubünden has yet to carry out a comprehensive investigation of the cart. They are reaching out to the community for assistance, inviting anyone who possesses knowledge regarding the object's function or how it was made to get in touch with them directly. Since that time, social media users have been buzzing with theories about the purpose of the bamboo structure. Some have proposed that it might have served as a cart for smuggling goods during World War I, while others believe it could be an early climbing apparatus utilized by adventurers or researchers, or perhaps even a component of a 20th-century aircraft. View pictures in App save up to 80% data. Andrew Mayovskyy – stock.adobe.com – for illustrative purposes only Several commenters concurred on the wagon's utility, suggesting that it likely facilitated the movement of supplies. "Given that the wheels appear unsuitable for supporting a heavy load for an extended period, I suggest that it was an early form of a winch designed to help transport supplies uphill," one individual noted. "It's a type of pull cart, designed for a person or mule to walk ahead of it, constructed from bamboo to ensure it's lightweight for navigating mountain trails and rough landscapes," added another. The Splügen Pass boasts a rich historical background that is important to consider. During the Roman period, it functioned as a significant trade route, as evidenced by historical sources such as the Roman Tabula Peutingeriana. With glaciers around the globe melting at an accelerating pace, it's anyone's guess what discoveries archaeologists might unearth next. More About:News

View pictures in App save up to 80% data. Unlocking the Mysteries of the Universe Through YouTube It's time for a most beautiful celestial event here in New England, and to make it even more exciting, there's an app for that, too. The free Night Sky app will allow you to be a bit more interactive. It's a powerful stargazing guide that, in this particular moment, will help you with all the planets lighting up the sky. According to the Star Walk website, get ready for the parade of planets if you will. How absolutely cool does that sound? On January 21 and 22, six of our planets will line the sky, and you can simply look up just after sunset for the show to begin. Welcome Venus, Mars, Jupiter, Saturn, Uranus, and Neptune. Whether you find yourself amidst the sparkling city lights of Boston or relaxing on a blanket by the shore of the New Hampshire Seacoast, it promises to be a truly enchanting experience. According to the Science Alert website, it's not uncommon for two or three planets to be on the same side of the Sun at the same time, but having several at the same time and getting to see most of them is pretty rare. That said, it will happen again next month, too, adding Mercury into the mix. Now, while we'll easily see Mars, Jupiter, Venus, and Saturn with our naked eye, grab some high-powered binoculars to make sure you can see Neptune and Uranus. From time to time, the planets align on the same side of the Sun during their orbital paths, allowing us to observe them simultaneously in the night sky. This celestial event will occur on the evenings of January 21 and February 28. Once again, shortly after sunset on the evenings of January 21 and 22, they will begin to show up, with the optimal time for viewing being one hour after the sun goes down. Again, the free Sky Night app will allow you to find the planets easily because they won't all be lined up right next to each other. Keep your fingers crossed for clear skies. Meanwhile, here's a video to get you prepped. 13 Maritime Superstitions of Fishermen and Sailors Gallery Attribution: Jolana Miller 7 Renowned Fast Food Chains Originating from New England We all recognize that America Runs on Dunkin, but it's not the sole major American fast food chain that originated in New England...

Stone Age Craftspeople Selected Their Materials Deliberately. A Recent Study Aims to Uncover the Reasons Behind Their Choices.

2025-03-25 00:36:49

To effectively engage with the simplest forms of technology, one needs to possess a certain level of intelligence. View pictures in App save up to 80% data. Ancient quartzite spearheads, akin to the tools examined in the research. However, which option would a Stone Age artisan opt for? Image credit: Ique Perez/Shutterstock.com The human Stone Age was, undeniably, the first step on a journey towards the species total technological dominance – but it didn’t have to be. After all, pick a rock that’s too soft, or too wonky, and our ancestors may never have made it past “ape with aspirations”. So how did they manage to get it so right? Recent research offers insights into this question, or at the very least, lays the groundwork for further exploration. By conducting direct experiments on different raw materials sourced from percussive tools at Melka Wakena, an archaeological site in the Ethiopian Highlands dating back 1.6 to 0.7 million years, scientists were able to deduce the qualities that rendered these materials beneficial to our prehistoric ancestors. They also examined the circumstances under which specific advantages were prioritized over others in their decision-making processes. “Our research shows that the material properties of the stones – such as suitability, quality, and durability – were likely crucial factors in the selection process by early hominins,” explained Dr Eduardo Paixão, a researcher at the University of Algarve, Portugal, and study lead, in a translated statement. Paixão remarked, “This indicates that they possessed a profound awareness of their surroundings and made intentional decisions.” It wasn’t always as straightforward as you might think, either. For as primitive as we like to think of our Stone Age ancestors being, they understood the nuances of rock way better than we do (save for the odd geologist out there): “Our experimental results show that, while two types of rock (ignimbrite and glassy ignimbrite) appear similar to the naked eye, they behave considerably differently,” explains the paper. The study highlights that glassy ignimbrite, sourced from a greater distance, posed some challenges in terms of convenience for use. However, it was noted to be “considerably tougher” and “the most uniform raw material available, exhibiting superior resistance.” Consequently, the softer variant of the rock, though more accessible, was overlooked in favor of “glassy ignimbrite, which was transported from afar as substantial flake blanks, specifically chosen for creating [large cutting tools].” It’s not just the results that are important here. As the paper makes clear, a lot of what we’ve traditionally understood about Stone Age technology has been based on… well, vibes, more or less: “in many cases, […] inferences about [artefacts’] specific functions are based on preconceived assumptions about their size and morphology,” the paper explains.  Even those that have been systematically analyzed are still kind of fuzzy, it adds, since “Differences in the physical properties of rocks are often described and organized by researchers in distinct categories of ‘raw material quality’. "It clarifies that, nonetheless, establishing and measuring this 'quality' is quite complex." In that respect, the new paper – and the project it marks a beginning to – is undoubtedly remarkable. It’s perhaps the first study to analyze these ancient stone tools on their own terms: not only performing a post-hoc analysis of the artefacts, but replicating their original use. And it’s paid off: already, the researchers have noticed that some properties, previously assumed to be one of these mysterious “qualities” of the rock itself, are actually the result of the tool’s use over time. Co-author Dr. João Marreiros stated, “The intentional choice of materials impacted the alterations observed on the tools' surfaces. This indicates that variations in archaeological discoveries are not merely coincidental.” “These discoveries provide fresh insights into the technological advancements of early human civilizations,” remarked Paixão. “We intend to conduct additional studies to gain a deeper understanding of the intricate choices made by these primitive artisans.” The study is published in the journal PLOS ONE.

The inaugural map of the Earth's vanished continent has been released.

2025-04-07 17:38:30

View pictures in App save up to 80% data. The initial map of Earth's vanished continent has been released. You may believe you're familiar with all the continents, but have you heard of Zealandia? In 2017, a previously unknown contingent of the shores of New Zealand was discovered - making headlines globally. Zealandia, known as Te Riu-a-Māui in the Māori language, covers more than 5 million square kilometres, making it twice the size of the subcontinent of India. You might be asking yourself why it wasn't uncovered earlier. The explanation lies in the fact that 95 percent of its landmass is hidden beneath the southwest Pacific Ocean, having vanished long before the arrival of humans on the planet. What remains above water are primarily a significant mountain range (the two islands of New Zealand) along with a few smaller oceanic islands. Not much information is available about the newly found continent, primarily because it is largely unreachable. Nevertheless, a group of geologists from various parts of the globe has created a fresh geological map that includes Zealandia. This map was developed through a blend of rock samples collected from the ocean and geophysical mapping techniques. As geologists explored the outer edges of Zealandia in search of samples, they uncovered significant sandstone formations along with deposits of basaltic rock pebbles. The sandstones are estimated to be approximately 95 million years old and include older granite and volcanic pebbles. This indicates that when Zealandia was above water, rivers originating from volcanic highlands deposited materials into tectonic basins. The highlands were once a bustling volcanic range around 30 to 50 million years ago, but they probably underwent significant erosion during the time when the sandstone was laid down. Geologists theorize that Zealandia experienced a gradual submersion approximately 40 million years ago, a conclusion supported by the finding of basalt pebbles linked to underwater volcanic activity. The study "Reconnaissance basement geology and tectonics of North Zealandia" was published in the journal Tectonics(2023).

(European Space Agency via AP) [ASSOCIATED PRESS] CAPE CANAVERAL, Fla. (AP) — A spacecraft has beamed back some of the best close-up photos yet of Mercury’s north pole. The European and Japanese robotic explorer swooped as close as 183 miles (295 kilometers) above Mercury’s night side before passing directly over the planet’s north pole. The European Space Agency released the stunning snapshots Thursday, showing the permanently shadowed craters at the top of of our solar system’s smallest, innermost planet. Cameras also recorded images of the adjacent volcanic plains and the largest impact crater on Mercury, which measures over 930 miles (1,500 kilometers) in diameter. This was the sixth and final flyby of Mercury for the BepiColombo spacecraft since its launch in 2018. The maneuver put the spacecraft on course to enter orbit around Mercury late next year. The spacecraft holds two orbiters, one for Europe and the other for Japan, that will circle the planet’s poles. The spacecraft is named in honor of the late Giuseppe (Bepi) Colombo, an Italian mathematician from the 20th century. He played a significant role in NASA's Mariner 10 mission to Mercury during the 1970s and, two decades later, contributed to the Italian Space Agency's tethered satellite project that was launched aboard U.S. space shuttles.

DNA Analysis Reveals Celtic Women Dominated Iron Age Britain 2,000 Years Ago

2025-03-16 14:40:16

The pioneering Iron Ladies. View pictures in App save up to 80% data. Boudicca, the iconic queen, is renowned for fiercely opposing the Romans. Image credit: Jane Rix/Shutterstock.com When the Romans first entered the British Isles, they found a land ruled by warrior queens and other high-status women – or at least, that’s how Julius Caesar and other witnesses described the situation in this new and strange territory. And while modern historians have tended to distrust these ancient Roman accounts as over-exaggerated and inaccurate, a new analysis of 2,000-year-old DNA suggests that women really were the big dogs in prehistoric Britain. The idea that these ancient societies may have revolved around females has previously been supported by finds in Celtic cemeteries in Dorset, southern England, where a tribe known as the Durotriges lived from roughly 100 BCE to 100 CE. At these sites, female burials typically contain the most lavish grave goods, suggesting that women may have held positions of political, military, and social influence. Building on these previous discoveries, researchers have now sequenced the DNA of 55 individuals from the Durotrigian burial site of Winterborne Kingston, along with two more from other nearby cemeteries. To gain a sense of how these ancient societies were structured, the study authors analyzed levels of diversity in mitochondrial DNA – which is inherited only from the mother – as well as the Y chromosome, which is transmitted from father to son. Consequently, these two segments of the genome can be utilized to track an individual's maternal and paternal ancestries, revealing that over two-thirds of the individuals interred at Winterborne Kingston are descendants of a previously unidentified maternal lineage.  “We reconstructed a family tree with many different branches and found most members traced their maternal lineage back to a single woman, who would have lived centuries before,” explained study author Dr Lara Cassidy in a statement. “In contrast, relationships through the father’s line were almost absent,” as evidenced by high levels of Y-chromosome diversity among the cemetery’s men. Such a finding suggests that these men all came from elsewhere, while the women were local. "According to Cassidy, this indicates that husbands relocated to their wives' communities after marriage, suggesting that land may have been inherited through the female lineage. This practice is referred to as matrilocality, which stands in opposition to the patrilocal societies that have traditionally been viewed as the standard in much of prehistory."  “Cassidy notes that this is the inaugural documentation of such a system in European prehistory, suggesting a trend towards female social and political empowerment. While this phenomenon is uncommon in contemporary societies, it may not have always been so.” View pictures in App save up to 80% data. This Durotrigian was buried with jewelry including an amulet depicting military victory.  Image credit: Bournemouth University Curious about the prevalence of matrilocal societies in ancient times, the researchers analyzed the genomes of individuals from 156 burial sites throughout Europe, dating from the Neolithic period to the Iron Age. Intriguingly, they discovered signs of matrilocal practices at six distinct locations, all located in Iron Age England. “Throughout Britain, we observed cemeteries indicating that the majority of individuals could trace their lineage back to a limited group of female ancestors,” stated study author Professor Dan Bradley. “In Yorkshire, for instance, a prominent maternal line was established prior to 400 BCE. We were taken aback to discover that this was a common occurrence with ancient origins across the island.”  Bringing things full circle, the researchers say their findings provide credence to the tales told by the likes of Julius Caesar and other Roman authors. According to these reports, the earliest British rulers were women, including the legendary warrior queens Boudicca and Cartimandua, both of whom kicked a significant chunk of Roman butt in the first century CE. “It’s been suggested that the Romans exaggerated the liberties of British women to paint a picture of an untamed society,” explains excavation director Dr Miles Russell. “But archaeology, and now genetics, implies women were influential in many spheres of Iron Age life.” The study is published in the journal Nature.

Researchers uncover 'submerged realms' concealed deep within Earth's mantle that defy expectations.

2025-03-20 11:49:46

A novel method for assessing formations deep within the Earth has revealed a multitude of previously unidentified masses in the planet's mantle. These anomalies bear a striking resemblance to submerged pieces of Earth's crust, yet they are found in locations that seem highly improbable. View pictures in App save up to 80% data. Recent studies have discovered several possible subducted slabs in unexpected areas within Earth's mantle, which is the second layer from the surface of our planet. Potential patches of Earth's ancient crust, sometimes called "sunken worlds," may have just been discovered deep within the mantle, thanks to a new way of mapping the inside of our planet. However, these mysterious blobs appear in places they should not, leaving researchers scratching their heads. For decades, scientists have been building up a better picture of Earth's interior by using seismographs — 3D images created by measuring how seismic waves from earthquakes reverberate deep within our planet. This method has helped scientists identify ancient sections of the planet's crust, known as subducted slabs, that have been pulled into the mantle through subduction zones where tectonic plates meet. For example, in October 2024, researchers announced the discovery of a section of seafloor that had sunk deep into the mantle below Easter Island. In a study published Nov. 4, 2024, in the journal Scientific Reports, researchers revealed that they had discovered "numerous" potential subducted slabs throughout Earth's mantle, using a new type of seismographic imaging. (Little information about the size, shape and exact locations of the blobs has been revealed so far.) In contrast to the previously recognized subducted slabs that are situated in regions of active or historically intense tectonic plate interactions, some of the newly discovered anomalies appear in locations devoid of any documented tectonic activity, including beneath the western Pacific Ocean. Consequently, the origins of these anomalies remain uncertain. "That's our dilemma," Thomas Schouten, a doctoral candidate at the ETH Zurich Geological Institute in Switzerland, said in a statement released Jan. 7. "With the new high-resolution model, we can see such anomalies everywhere in the Earth's mantle. But we don't know exactly what they are." View pictures in App save up to 80% data. The latest model reveals areas within the Earth's mantle where seismic waves move at a reduced speed (indicated in blue), implying the presence of potentially subducted slab fragments. There could be alternative interpretations for the recently identified blobs. One possibility is that they are composed of crust-like substances that originated from the mantle's formation 4 billion years ago. Another option is that these blobs are made up of other dense materials that have developed within the mantle over the last few hundred million years. Nonetheless, these are merely other hypotheses. Currently, the identity of these blobs continues to be a "significant enigma," as stated by representatives from ETH Zurich. Discovering "submerged realms" Up to this point, our understanding of the Earth's interior has relied on the integration of various seismographs produced by individual earthquakes occurring around the world. However, in a recent study, scientists employed an innovative technique called full-waveform inversion. This approach utilizes computer simulations to merge these seismographs into a cohesive and detailed representation. This is a computationally intensive method, and to pull it off, researchers had to run the model on the Piz Daint supercomputer at the Swiss National Supercomputer Center in Lugano — formerly Europe's most powerful computer — to crunch the numbers. View pictures in App save up to 80% data. The recently identified blobs are situated away from any existing or historical fault lines associated with tectonic plates. Study co-author Andreas Fichtner, a seismologist at ETH Zurich who created the full-waveform model used in the new research, compared the use of full-waveform inversion to medical imaging advancements. Imagine a doctor has been studying the circulatory system for decades, Fichtner said. "Then, if you give [them] a new, better examination tool, [they] suddenly see an artery in the buttock that doesn't really belong there," Fichtner explained. "That's exactly how we feel about the new findings." Scientists speculate that the recently identified blobs could be subducted slabs, primarily due to the fact that seismic waves pass through them at identical speeds. However, this does not ensure that they are indeed the same entity, and further investigation is required to determine if they truly share characteristics. "To understand the varying speeds of the different wave types, we need to assess the various material parameters," Schouten explained. "In essence, we must investigate the underlying material properties that influence wave speed."

How Dinosaurs Shaped American Identity

The slogan “Make America Great Again,” associated with the Trump campaign, conveys a desire to revert to a nostalgic vision of a time when America was perceived as better and more genuinely “American.” Although the idealized past championed by certain MAGA supporters may not accurately reflect historical realities, it resonates with anxieties surrounding the transformations instigated by decades of immigration and civil rights advancements that have fostered greater diversity and inclusivity in the nation. This isn’t the first instance in American history where notions of the past have been leveraged to shape the concept of national identity. Interestingly, remnants of historical discussions surrounding American identity can be uncovered in unexpected locations: dinosaur museums. While dinosaurs themselves weren’t engaging in identity debates, the 19th-century Americans who established the initial dinosaur museums were very much involved in such dialogues. The discovery of these fossils revolutionized the way Americans perceived their own identity and contributed to the ongoing discourse regarding who has the right to identify as American. The discovery of fossils in the 19th century indicated that the territory now known as the United States had a history that stretched far beyond earlier assumptions. This newfound awareness of "deep time" allowed the inhabitants of the New World to distinguish their identity in contrast to the established narratives of the Old World in Europe. Concurrently, those of European ancestry in America leveraged the concept of "deep time" to marginalize Indigenous peoples and African Americans from the narrative of American history, thus positioning white Americans of European descent as the central figures in this evolving story. Additional Insights from TIME Deep time refers to the vast expanse of time required for planetary and cosmic processes to develop. Consider that the universe has existed for approximately 14.5 billion years, while our Earth formed around 4.5 billion years ago, and the oldest surface rocks in North America date back nearly as far. The idea of deep time emerged in the United States between the American Revolution and the invention of the automobile. It replaced the older idea that the Earth was only about 6,000 years old and that America was a new nation on a very young continent in the very New World. Many people at the time of the Revolution thought that the New World had risen last from the receding waters of the Flood that had ferried Noah’s Ark to safety. The Old World of Europe had risen earlier, allowing its climate to warm up nicely. For Europeans, the unfamiliarity of the New World accounted for their perception that conditions in America were inferior to those in Europe. The damp climate of America was believed to cause all forms of life to diminish in size and strength, affecting plants, animals, and even humans. Take elephants, for example; they were thought to have evolved into smaller tapirs with short trunks and legs. As for the Indigenous populations, it was suggested that the lesser facial hair of Indigenous men compared to their European counterparts indicated a deficiency in masculinity that prevented them from growing beards. In 1776, the American colonies proclaimed their independence from Britain, breaking free not only from British rule but also from the European notions of American inferiority. In the coming hundred years, Americans developed a distinctive national identity rooted in the concept of time. In contrast to the aged and decaying monarchies of Europe, the United States emerged as a youthful and dynamic nation. However, Americans quickly embraced a novel concept—that their nation was, in fact, ancient and profoundly established. Although their republic was recent, the territory it occupied was not just older than Europe; it was the oldest on the planet: God's initial creation, a pristine Eden designed as the backdrop for a magnificent national destiny. In the early 1820s, the discovery of trilobites along the banks of the newly constructed Erie Canal provided compelling evidence for the ancient history of the land. These peculiar fossils, resembling horseshoe crabs and found deeply embedded in the rock layers, sparked curiosity among America’s first professional geologists. Although precise dating methods for fossils and rocks would not emerge until the advent of radiometric dating in the early 20th century, the significant depth at which the trilobites were located indicated that they were likely remnants of some of the earliest life forms on our planet. The geologists came to understand that this was not the well-known garden from Genesis, but rather a submerged paradise—possibly the original ocean created by God, teeming with life and home to the earliest beings, the humble trilobites. Americans sent trilobite fossils to European researchers who had discovered comparable specimens. The industrial revolution prompted both Americans and Europeans to excavate the Earth extensively in search of the ores and minerals essential for modern industries, particularly coal mining. However, this extensive digging also ignited a transformative shift in understanding the planet's age. With scientists from both sides of the Atlantic uncovering trilobites within the same geological layers, the notion of superiority in age became obsolete. American scientists reveled in the newfound evidence suggesting that America was as ancient as Europe—perhaps even older. As the 19th century unfolded, the concept of time took on new dimensions for Americans venturing westward. White plantation owners migrating into areas like Alabama, Mississippi, and Louisiana—known as the “Cotton Kingdom”—were on a quest for fertile land. To aid in their search, they enlisted geologists who meticulously examined rivers and plantations in pursuit of the richest soils. In their explorations, they stumbled upon fossils of ancient sea creatures such as Mosasaurus, the fearsome predator of the primordial oceans. The geologists proclaimed that the South’s abundant fertility was rooted in its dark, Cretaceous (meaning “chalky”) soils. In the years leading up to the Civil War, white Americans developed a harmful form of "science" centered around the rich black-belt soil of the Cotton Kingdom. They believed that long ago, God had fashioned a vibrant ocean filled with beings such as the Mosasaurus. As this ocean receded, its inhabitants died off, leaving behind fossilized remains that contributed to the fertile, chalky lands of the South. Certain white Americans linked the supposed inferiority of Black individuals to the rich black-belt soils of the South. They believed that, beyond simply equipping the American South for slavery with its fertile land, God had also fashioned Black people with the skin color best suited for laboring on that soil. “Only blacks can cultivate the fertile lowlands of this region,” remarked a geologist in 1844 during his exploration of the South. This understanding of geological history further solidified racial hierarchies within the United States. Following the Civil War, white Americans ventured further into the Nebraska territory, crafting a fresh American identity rooted in the concept of deep time. As they excavated the earth to lay down railroad tracks, they unearthed massive, formidable dinosaur bones, which they named Brontosaurus (meaning thunder lizard) and Tyrannosaurus Rex (translating to tyrant lizard king). Western geologists observed that with the extinction of certain dinosaurs in the fossil record, a fresh array of fossils emerged above them: mammals. This era, marked by the rise of mammals, was aptly named the Eocene, signifying the beginning of a new age. Among the new life forms that emerged was Eohippus, a small “dawn horse” that roamed the early grasslands of America. The narrative constructed by white scientists regarding the earliest mammals illustrated the ways in which deep time could be used to marginalize certain groups. According to these scientists, the original inhabitants of America were not the Sioux or other Indigenous peoples. Long ago, millions of years in the past, the rich soil of America birthed incredible beings such as Eohippus. Over time, these small equines journeyed to Asia, where they evolved into larger forms, sharing the robust spirit of American life with the globe. As humans rode these majestic animals, civilizations flourished from the vast steppes of Asia to the ancient realms of Greece, Rome, and beyond into Europe. Following the year 1492, the Spanish Conquistadors returned the horse to its homeland: America. In this narrative, neither the Sioux nor the Spaniards can claim the title of the first Americans. The true pioneers of America were the mammals of the Eocene epoch. Prior to them, the land was inhabited by the earliest reptiles, the dinosaurs. Even before that, the initial life forms were the trilobites. View pictures in App save up to 80% data. The essence of the narrative was that Native Americans held no greater legitimacy as true Americans than their white counterparts. This perspective was voiced by some of the earliest dinosaur hunters in the Western United States. The vast timeline of deep time incorporated trilobites, dinosaurs, and the earliest mammals into the history of the nation. In contrast to this immense and captivating temporal framework, the importance of American Indians diminished. They ceased to be recognized as the original Americans. The next time you marvel at the enormous fossils displayed in a dinosaur museum, keep in mind that you’re also peering into a chapter of U.S. history and the ongoing discussion about what it truly means to be American.

Image captured from “Marine life forms a multitude of eyes using its shell”, Source: “YouTube”, Uploaded by “Science Journal” Evolution describes how organisms developed from earlier life forms during the earth’s history. Charles Darwin introduced the concept of evolution. The evolution of chitons, a class of marine mollusks known as Polyplacophora, is a fascinating subject that showcases the adaptability and resilience of these creatures over millions of years. Chitons are characterized by their distinctive eight overlapping shell plates, which provide protection and flexibility. Fossil evidence suggests that chitons have existed for at least 500 million years, dating back to the Cambrian period. Their evolutionary history reflects significant changes in marine environments, with chitons adapting to various habitats ranging from rocky shorelines to deep-sea ecosystems. Throughout their evolution, chitons have developed specialized feeding mechanisms, such as their radula, which allows them to scrape algae and other organic material from surfaces. Their ability to cling tightly to rocks using their muscular foot has also contributed to their survival in turbulent coastal waters. As researchers continue to study the genetic and morphological diversity of chitons, they gain insights into how these creatures have evolved in response to environmental changes and ecological pressures. Understanding chitons not only sheds light on their evolutionary journey but also provides valuable information about marine biodiversity and the health of ocean ecosystems.

In 2024, X-class solar flares reached unprecedented levels and may increase even more this year; however, experts suggest that the sun isn't solely responsible for this phenomenon.

2025-04-08 11:27:11

In 2024, the occurrence of X-class solar flares reached levels not seen in over thirty years. This surge was primarily attributed to the onset of solar maximum, although various other influences contributed to this increase as well. View pictures in App save up to 80% data. In 2024, the sun entered its most intense period known as solar maximum, resulting in a remarkable surge of powerful X-class flares erupting from our star. The number of X-class solar flares — the most powerful and potentially dangerous class of solar eruption — hit a new record high in 2024. The spike highlights that we are currently experiencing a surprisingly active solar maximum, which could continue to intensify this year. However, experts informed Live Science that solar activity might not be the sole factor contributing to the dramatic increase in the number of supercharged solar explosions observed last year. There were a total of 54 X-class flares in 2024, according to SpaceWeatherLive.com, which maintains the oldest and most accurate publicly available dataset on solar flares. That is the highest total since at least 1996, when this dataset began. NASA has been tracking solar flare activity since the mid-1970s, but earlier data has not been made publicly available and is less reliable than modern records, SpaceWeatherLive.com representatives told Live Science in an email. The former highest count of X-class flares in the dataset stood at 34, noted in 2001. Additionally, there were only four other years — 2000, 2003, 2005, and 2014 — when the annual total exceeded 20. Thus, the total from last year signifies an unexpectedly significant increase in the occurrence of X-class flares. View pictures in App save up to 80% data. On October 3, 2024, a powerful X9 magnitude solar flare — the strongest of the ongoing solar cycle — erupted from the sun, sending a coronal mass ejection (CME) hurtling straight toward Earth. The effects of the more frequent X-class flares were widely felt on Earth in 2024. For example, in May, a quickfire succession of at least four X-class flares launched clouds of plasma, known as coronal mass ejections (CMEs), that slammed into Earth and sparked the strongest geomagnetic storm in 21 years, which in turn triggered some of the most vibrant and widespread aurora displays in our skies over the last 500 years. What caused the significant increase in X-class flares last year? Heightened solar activity The obvious reason for the increased frequency is the arrival of solar maximum. This peak in the sun's roughly 11-year cycle of activity, which is triggered by the weakening and eventual flipping of the sun's magnetic field, has been surprisingly active so far and is expected to continue well into 2025 and possibly beyond. In October 2024, scientists from NASA and the international Solar Cycle Prediction Panel (SCPP) announced that we have entered solar maximum and that the explosive peak likely started early last year, which was sooner than they had initially predicted. The ongoing maximum has also proved to be more active than most scientists had initially forecast. For example, in August, the number of visible sunspots on our home star, which is a key metric for monitoring solar activity, reached a 23-year high. View pictures in App save up to 80% data. In August, the count of visible sunspots on the solar surface reached its highest level in 23 years. This timelapse image illustrates the movement of these sunspots as they traversed the sun's near side. But the number of X-class flares has been the biggest shock for most solar physicists. "I think we have all been surprised [about the number of flares]," Hugh Hudson, a solar physicist at the University of Glasgow in the U.K., told Live Science. Certain researchers, such as Hudson, contend that the rise in X-class flares can be exclusively linked to heightened activity during the solar maximum phase. Conversely, other specialists argue that while the sun's peak has certainly contributed significantly to this increase, it is not the sole factor. These experts suggest that the unprecedented number of recorded X-class flares is also a result of advancements in our detection methods, which may be skewing the overall assessment. Identifying solar flares Most X-class flares are pretty hard to miss, Scott McIntosh, a solar physicist and vice president of the new space weather solutions company Lynker Space, told Live Science. "These events are so massive they kinda smack you in the face," he said. Nevertheless, McIntosh noted that we are unable to observe all of them. For starters, we can only properly see solar flares on the side of the sun facing Earth, although some farside explosions are so massive that we can still see the gigantic CMEs they hurl into space. This doesn't change much because we have only ever been able to see the sun's nearside eruptions. But it can also be hard to spot and properly measure solar flares around the edge of the sun's limbs because we cannot always see them properly. According to McIntosh, this suggests that we may have historically overlooked as much as an additional 15% of the sun's X-class flares. In recent decades, researchers have deployed a number of advanced spacecraft designed to observe the sun, which have likely improved their ability to detect certain flares that may have gone unnoticed in the past, according to McIntosh. "These new tools have revealed the frequency of events that have been directed away from our planet," he noted. There is a possibility that we may have overlooked some X-class flares in the past that were on the borderline between being classified as X-class and M-class, which is the second-highest category for solar flares. View pictures in App save up to 80% data. Innovative spacecraft such as NASA's Solar and Heliospheric Observatory (SOHO) are enhancing researchers' ability to monitor and analyze solar phenomena. Carl Shneider, a space systems scientist at the University of Luxembourg and an advisor at private space weather forecasting company Mission Space, also believes that we are getting better at spotting X-class flares. "Advances in science and technology are continuously improving our ability to monitor solar activity and its impact on Earth's environment," Shneider told Live Science. "Every new mission, observational point, numerical model or theory improves our understanding." Nonetheless, these advancements can serve as a double-edged sword, as Shneider pointed out, "this progress complicates direct comparisons between contemporary data and historical observations." However, not everyone shares this belief. Hudson, a researcher with decades of experience in studying solar flares, asserts that "the guidelines [for identifying X-class flares] remain unchanged" and claims that we have probably overlooked "none" of these eruptions in the past several solar cycles. Will there be additional content in the future? The solar maximum is anticipated to persist until at least 2025, and possibly extend into 2026; however, its conclusion will only be determined in hindsight. Typically regarded as the most dynamic period of the solar cycle, solar maximum can still see elevated flare activity for several months or even years following its peak. New research also suggests that solar activity can peak a few years after solar maximum, during a period when different parts of the sun's magnetic field vie for dominance, which some researchers have dubbed the "battle zone." View pictures in App save up to 80% data. In 2025, there is a significant possibility that we will witness an increase in both the intensity and frequency of X-class solar flares. "I believe the record will keep expanding in the coming years," said McIntosh, a key advocate for the battle zone concept. Nonetheless, he noted, "it's hard to predict for sure." Shneider is of the opinion that we have yet to reach the maximum level of solar activity, stating, "The occurrence of these events may continue to be elevated for a number of additional years." 2025 has already started strong with three X-class flares in the first four days of the year, according to SpaceWeatherLive.com. It is also possible that we could see much more powerful X-class flares in the coming years. The most powerful flare of the current solar cycle was an X9 magnitude blast on Oct. 3, 2024. But during the last two solar cycles, there have been 14 different X-class flares with a higher magnitude, despite flares being less frequent at the time. Hudson remarked that a rise in frequency doesn't ensure the occurrence of stronger flares. "However, I find it strange that we haven't observed more intense flares so far," he noted.

Forget about air purifiers – the groundbreaking 'air sterilizer' has arrived, boasting the ability to immediately neutralize Covid, cold, and flu viruses.

What’s your latest strategy for combating seasonal illnesses? View pictures in App save up to 80% data. (Image source: EcoAir) EcoAir AVS inactivates virus particles using heat Traditional purifiers capture, rather than inactivating, harmful microbes EcoAir's claims have been independently verified by a scientific research company Most of us know about air purifiers, but EcoAir, a brand specializing in air care appliances, has taken a step further by introducing what it claims to be the world's first air sterilizer. The EcoAir Anti-Covid AVS is said to be capable of removing viruses and bacteria from the air, including those responsible for colds, flu, and, of course, Covid-19. Today's best air purifiers can only capture virus particles, not inactivate them – is this new approach your new best defense agains seasonal bugs? I got in touch with EcoAir co-founder and CEO Noel Fok to learn exactly how it works. "Viruses are not classified as living organisms, meaning they cannot be killed in the traditional sense," Fok clarifies. "Nonetheless, they can be inactivated or eradicated through heat exposure. The EcoAir AVS air sterilizer effectively removes 99.9% of viruses from the air by utilizing Thermo-Clean technology, which achieves a core temperature exceeding 200C [392F], thereby neutralizing harmful microbes." He states, "AVS will eliminate bacteria as it is a living entity, utilizing the same exposure to Thermo-Clean technology. In both scenarios, the harmful microorganisms are destroyed by heat and are not released back into the atmosphere." Those claims have been independently tested and verified by MRIGlobal – a research organization focused on health and safety innovations. View pictures in App save up to 80% data. (Image source: EcoAir) Another impressive feature of this 'air sterilizer' is its rapid effectiveness. It can remove airborne viruses and bacteria in just one pass, achieving this nearly instantaneously, in only 0.01 seconds. Laboratory tests conducted by MRIGlobal showed that the EcoAir AVS is capable of inactivating 99.9% of viruses in a 30m³ space within 90 minutes. What does the future hold for air purifiers? I also requested Fok to elaborate on the advantages of the EcoAir AVS when compared to a standard air purifier. "Conventional air purifiers trap microorganisms using HEPA filters, which require replacement and lead to extra costs," he explained. "By inactivating the virus, it is effectively eliminated, preventing it from infecting any living being and triggering illness." The EcoAir AVS is equipped with a reusable filter that doesn't require frequent changes. The nano silver filter can be cleaned every two weeks, and EcoAir recommends replacing it annually. Additionally, there are other established techniques for eliminating viruses and bacteria, but they are considerably more time-consuming compared to EcoAir AVS's rapid 0.01-second method. For example, ION systems require approximately 30 seconds, while UV-C technology takes about nine seconds to achieve similar results. While the practical results of this appliance are similar to that of a good air purifier, Fok's claims that the AVS represents "a huge breakthrough, not only for EcoAir but for the industry as a whole" could prove accurate. The new process certainly seems more thorough and efficient, and it's not significantly more expensive than a good air purifier either – the EcoAir Anti-Covid AVS is currently available to buy from the EcoAir website, priced at £349.98 (it's not currently available in the US or Australia, but that's equivalent to around $430 / AU$700). Could this be the new technology that changes the way we purify air? You may also find these interesting...

China is gearing up to construct a massive solar energy array in space, which has the potential to harvest more energy in a single year than the total amount of oil available on our planet.

2025-03-22 13:10:47

China has revealed its intentions to construct a massive solar power space station, which will be transported into orbit in segments with the help of the country's newly developed heavy-lift rockets. View pictures in App save up to 80% data. On July 23, 2020, a Chinese Long March 5 rocket successfully lifted off from the Wenchang Satellite Launch Center located on Hainan Island, carrying the Tianwen-1 Mars rover, lander, and orbiter for the China National Space Administration. Chinese researchers have unveiled a proposal to construct a massive solar power facility in space, measuring 0.6 miles (1 kilometer) in width, which will transmit a steady stream of energy to Earth using microwave technology. The project, which will see its components lofted to a geostationary orbit above Earth using super-heavy rockets, has been dubbed "another Three Gorges Dam project above the Earth." The Three Gorges Dam, located in the middle of the Yangtze river in central China, is the world's largest hydropower project and generates 100 billion kilowatt-hours of electricity each year. According to one NASA scientist, the dam is so large that, if completely filled, the mass of the water contained within would lengthen Earth's days by 0.06 microseconds. The new project, according to lead scientist Long Lehao, the chief designer of China’s Long March rockets, would be "as significant as moving the Three Gorges Dam to a geostationary orbit 36,000km (22,370 miles) above the Earth." "This is an incredible project to look forward to," Long added during a lecture in October hosted by the Chinese Academy of Sciences (CAS), as reported by the South China Morning Post. "The energy collected in one year would be equivalent to the total amount of oil that can be extracted from the Earth." Despite recent advances in the cheapness and efficiency of solar power, the technology still faces some fundamental limitations — such as intermittent cloud cover and most of the atmosphere absorbing solar radiation before it hits the ground. Researchers have put forward various technologies for Space-Based Solar Power (SBSP) that would allow for the ongoing collection and transmission of solar energy from space, where sunlight is ten times more potent than what we experience on Earth's surface. However, constructing a sufficiently large array would require numerous launches, resulting in the majority of proposals not being realized. To overcome this challenge, Long and his team are working on the development of the Long March-9 (CZ-9) reusable heavy-lift rocket, which will have a lift capacity of at least 150 tons (136 metric tons). Besides being used for satellites, the rocket will also be key to China's plans to reach the moon — where it wants to build an international lunar research base by 2035. China isn't the only nation eyeing plans for solar satellite arrays. The U.S. companies Lockheed Martin and Northrop Grumman, the European Space Agency, and Japan's JAXA space agency have also been investigating the technology, with the latter scheduling the launch of a small, proof-of-concept satellite this year to assess its feasibility.

Antarctica 'pyramid': The oddly symmetrical peak that ignited a significant alien conspiracy theory

2025-03-10 08:52:07

Antarctica boasts a mountain that resembles a flawless pyramid, yet despite the claims of conspiracy theorists, the mountain's four evenly shaped sides were created by natural geological processes. View pictures in App save up to 80% data. In 2016, a pyramid-shaped mountain located in Antarctica gained widespread attention on the internet. FAST FACTS Name: Unnamed peak in the Ellsworth Mountains Location: Antarctica Why it's incredible: The mountain looks like a human-made pyramid. A mountain that's hidden in a sea of snow in Antarctica looks strikingly like an ancient Egyptian pyramid when viewed from above. But no human (or alien) hands were needed to build this peak — it was forged through the slow, grinding process of erosion. The pyramidal mountain, which doesn't have a formal name, became internet-famous in 2016, but scientists likely knew about it before then, Mauri Pelto, a professor of environmental science at Nichols College in Dudley, Massachusetts, previously told Live Science. A research base for climate scientists sits just south of the mountain in an area called the Patriot Hills, and "you can probably see this mountain from up there," Pelto said. Antarctica's "pyramid" is about 4,150 feet (1,265 meters) tall, or about one-fifth the height of Denali, the tallest mountain in North America. It has four steep sides and is located in the southern Ellsworth Mountains — a chain of jagged peaks first spotted during a flight by American aviator Lincoln Ellsworth in 1935, according to a U.S. Geological Survey (USGS) research paper published in 2007. The region is known for holding 500 million-year-old fossils of trilobites and other critters dating to the Cambrian period (541 million to 485.4 million years ago). The slopes of the mountain were probably shaped into a pyramid-like form over hundreds of millions of years due to erosion. According to Pelto, the rocks could have experienced freeze-thaw erosion, a process where water and snow seep into tiny fissures during the day and freeze overnight. As the water freezes, it expands within the cracks, increasing their size under pressure, which ultimately leads to significant pieces of rock breaking away from the mountain. According to Pelto, three sides of the pyramidal mountain seem to have eroded uniformly, whereas the eastern ridge has developed separately. Pelto noted that freeze-thaw erosion likely shaped additional pyramidal peaks, including the Matterhorn in the Swiss Alps. Various conspiracy theories sprung up to explain the shape of Antarctica's pyramid mountain when it went viral in 2016, with theorists contemplating the involvement of a forgotten civilization or aliens from outer space. But "this is just a mountain that looks like a pyramid," Eric Rignot, a professor of Earth system science at the University of California, Irvine and senior research scientist at NASA's Jet Propulsion Laboratory, previously told Live Science. "Pyramid shapes are not impossible — many peaks partially look like pyramids, but they only have one to two faces like that, rarely four."

A study has revealed that the genetic variations observed in Chornobyl dogs are not a result of mutations.

2025-03-18 03:52:06

View pictures in App save up to 80% data. Source: Norman Kleiman Radiation-induced mutation is unlikely to have induced genetic differences between dog populations in Chornobyl City and the nearby Chornobyl Nuclear Power Plant (NPP), according to a new study in PLOS ONE from North Carolina State University and Columbia University Mailman School of Public Health. The study has implications for understanding the effects of environmental contamination on populations over time. "According to Matthew Breen, Oscar J. Fletcher Distinguished Professor of Comparative Oncology Genetics at NC State, 'We have been studying two dog populations that are only 16 kilometers, or roughly 10 miles, apart, yet they exhibit significant genetic differences.'" "We aim to explore whether prolonged low-level exposure to environmental toxins like radiation and lead could account for some of these disparities." Breen serves as the lead author of the research. In earlier research, the team examined genetic variations throughout the genome and pinpointed 391 unique regions in dogs that were distinct between the two populations. Among these regions, several harbored genes linked to the repair of DNA damage. In their latest study, the researchers took a more thorough approach, exploring the dogs' genomes to uncover signs of mutations that might have built up over time. "Initially, we placed the genetic differences between two dog populations into context, revealing that the genetics of dogs from Chornobyl City closely resembled those of dog populations in Russia, Poland, and nearby regions," explains Megan Dillon, a Ph.D. candidate at NC State and the primary author of the research. "This allowed us to utilize the dogs from Chornobyl City as a control group for comparison with the dogs from the nuclear power plant." The research team initially focused on identifying differences at the chromosomal level, subsequently narrowing their investigation to smaller genomic intervals, and finally examining variations at the single nucleotide level. Their goal was to uncover abnormalities and signs of accumulated mutations in germ line DNA—alterations that take place in the DNA of reproductive cells and are inherited from parents to their descendants over generations. "Breen explains, 'It's similar to utilizing the zoom feature on your phone's camera to capture finer details; we begin with a broad perspective of a subject and then focus in closely.'" "It is understood that high levels of radiation exposure can lead to instability starting from the chromosomal level. Although this dog population is over 30 generations separated from the dogs that lived through the 1986 disaster, any mutations that might have provided a survival benefit to those original dogs would likely still be identifiable. However, we did not observe any such evidence in these dogs." Although researchers did not find any evidence of genetic mutation, they emphasize that this does not exclude the possibility that selective pressures may account for the differences observed between the two dog populations. "Dillon explains that, in human context, this situation resembles examining a population that has lived hundreds of years after the disaster occurred." "It’s conceivable that the dogs that lived long enough to reproduce possessed certain genetic traits that enhanced their survival chances. This suggests that there might have been significant selective pressure initially, and subsequently, the dogs at the power plant stayed isolated from the urban population. Exploring this question is a crucial next step that we are currently pursuing." The researchers highlight that these results are just a fragment of the broader context regarding how negative environmental factors can impact the health of both dogs and humans. "While many consider the Chornobyl nuclear disaster to be a localized radiological event in a remote part of Ukraine, the health risks extend far beyond that," explains Norman Kleiman, a co-author and professor of environmental health sciences at Columbia University School of Public Health. "This is attributed to the various other hazardous substances, such as heavy metals, lead dust, pesticides, and asbestos, that were dispersed into the environment during the cleanup and remediation efforts spanning over thirty years." "Although no one currently resides at the NPP or in Pripyat, prior to the Russian invasion, thousands of individuals were still employed there daily, engaged in remediation and construction efforts in the vicinity," Kleiman explains. "Examining companion animals such as these dogs provides insight into the potential health hazards that people may encounter." In addition to looking at the genetics of the dogs, the team also recently identified differences in ticks recovered from the dogs at the power plant and Chornobyl City and the prevalence of the pathogens they transmit. These results, published in the journal Parasites and Vectors, may reflect differential exposures to both ticks and microbes at the two locations. Kleiman emphasized, "The significance of ongoing research into the environmental health implications of major disasters like this cannot be understated. With our societies becoming more technological and industrialized, it is inevitable that we will face similar disasters in the future. We must comprehend the potential health hazards and identify the most effective ways to safeguard individuals." More information: Megan N.

Mars rock samples might hold clues to extraterrestrial life, but will NASA be able to return them to Earth?

2025-03-23 00:02:45

NASA plans to investigate two distinct methods for retrieving Mars rock samples gathered by the Perseverance rover, with the potential that these samples may hold clues to the existence of extraterrestrial life. View pictures in App save up to 80% data. A photomontage showcasing the tubes filled with Martian samples that NASA intends to retrieve and return to Earth. NASA has announced two potential plans for retrieving rocks from Mars that may contain evidence of alien life. Since its launch in 2021, NASA's Perseverance rover has been actively gathering rocks and sediments from a historic lakebed on Mars. Nevertheless, NASA is currently faced with the challenge of figuring out how to return these samples to Earth for further examination. The original Mars Sample Return Program called for collecting the Perseverance samples by 2033, but delays and spiraling costs forced NASA back to the drawing board last year. NASA will now explore two new landing strategies for retrieving the rock samples before deciding on which one to pursue in 2026, according to a statement released on Tuesday (Jan. 7). "Pursuing two potential paths forward will ensure that NASA is able to bring these samples back from Mars with significant cost and schedule saving compared to the previous plan," Bill Nelson, NASA administrator, said in the statement. "These samples have the potential to change the way we understand Mars, our universe, and – ultimately – ourselves." The search for extraterrestrial life on Mars There's no guarantee that life ever existed on Mars, but if it did, then it's possible the Perseverance rover may already have found signs of it in the Jezero crater lakebed. Scientists won't know for sure what's in the samples until they get them back to Earth and study them in a lab. NASA's Mars Sample Return Program was initially supposed to cost $7 billion, but when the mission's estimated price tag climbed to $11 billion — an upper-end estimate calculated by an independent review board — and was set to be delayed until 2040, the agency announced a major program overhaul, Live Science's sister site Space.com reported. In September 2024, NASA approved 11 sample return proposals submitted by researchers and private firms to enhance the program. As part of this recent announcement, NASA will investigate and assess two of these proposals. Two routes ahead The first option relies on a tried and tested landing system design involving a rocket-powered sky crane, which uses cables to lower down the lander. NASA used this method to land the Perseverance rover on Mars in the first place, and it's estimated to cost between $6.6 billion and $7.7 billion. The second option relies on new commercial capabilities from private industry and is estimated to cost between $5.8 billion and $7.1 billion. NASA didn't discuss the commercial option in detail because of concerns about proprietary technologies and designs, Space.com reported. Regardless of which method NASA chooses, the landing system will use a smaller, modified version of the Mars Ascent Vehicle to carry the rock samples into orbit. The European Space Agency’s Earth Return Orbiter — a planned spacecraft that will launch no sooner than 2027 — will then collect and transport the samples back to Earth. "Mars Sample Return will allow scientists to understand the planet's geological history and the evolution of climate on this barren planet where life may have existed in the past and shed light on the early solar system before life began here on Earth," Nicola Fox, associate administrator for the NASA Science Mission Directorate, said in the statement. "This will also prepare us to safely send the first human explorers to Mars."

Scientists are amazed by the revelation of a novel technique for decomposing plastic: 'This represents a revolutionary advancement in technology.'

2025-04-08 09:23:55

View pictures in App save up to 80% data. Image Courtesy: iStock Scientists in South Korea have developed a new method of decomposing one of the world's most common types of plastic, BusinessKorea reported. The breakthrough could have major implications in plastic recycling. Polyethylene terephthalate, more commonly known as PET plastic, is one of the more ubiquitous types of plastic, used in everyday items such as plastic soda and water bottles, clothing, seatbelts, and more. It is usually made from crude oil and causes environmental harm at every stage of its production and life cycle. In order to recycle PET plastics more efficiently, scientists developed a biocatalyst (a substance that increases the rate of a chemical reaction) named KUBU-M12, which is able to break down plastic in a way that mimics how natural substances decompose. According to reports, KUBU-M12 has achieved the highest recorded performance for a biocatalyst in plastic decomposition to date. "This is a groundbreaking technology that enables permanent recycling of even contaminated plastics that cannot be recycled," said research co-lead Professor Kim Kyung-jin of the Department of Biotechnology at Kyungpook National University. While it is vital that our society moves away from traditional plastic products, instead embracing some of the many alternatives that now exist, there is still an astonishing amount of oil-derived plastic in existence, and it's not going anywhere on its own.  So, it stands to reason that we need ways to recycle this plastic efficiently instead of just letting it pile up in our landfills, in the environment, and in our oceans, where it is responsible for killing huge amounts of marine life every year. In the United States, as little as 5% of plastic waste actually gets recycled, per Beyond Plastics — whether you go through the trouble of sorting it or not. While it would still require some amount of political will to actually make it happen, enhanced recycling technologies could spur some governments to improve those numbers.

A Restful Night's Sleep Refreshes the Mind Similar to How a Dishwasher Cleans Dishes – Yet Caution is Advised with Sleep Medications.

2025-03-16 19:03:20

View pictures in App save up to 80% data. Acknowledgment: Nadia Alzoubi and Natalie Hauglund Recent studies indicate that a restful night's sleep can refresh your mind, much like starting a dishwasher before sleeping and waking up to find everything tidy and organized in your thoughts. A team of scientists from around the world explains the process as a method of clearing out the waste that accumulates in the brain while we are awake. Their research also sheds light on how sleeping medications might interfere with the brain's "brainwashing" mechanisms, which could have lasting impacts on cognitive abilities. Scientists have discovered that the brain features an inherent waste clearance mechanism known as the 'glymphatic system.' This system facilitates the circulation of fluid within the brain and spinal cord to help eliminate waste. This process aids in eliminating harmful proteins that create sticky plaques associated with neurological conditions like Alzheimer's disease; however, the underlying mechanisms that propel this system have been elusive until recently. Researchers at the University of Copenhagen in Denmark discovered that a molecule known as norepinephrine is crucial for the brain's cleansing process in mice. In the deep stages of sleep, the brainstem emits small bursts of norepinephrine approximately every 50 seconds. The lead researcher of the study, Professor Maiken Nedergaard from the University of Rochester in New York, elucidated that norepinephrine causes blood vessels to constrict, producing slow pulsations that establish a rhythmic movement in the adjacent fluid, facilitating the removal of waste. She remarked, “It’s similar to starting the dishwasher before heading to sleep and waking up to a refreshed mind.” "We're fundamentally exploring the factors that influence this mechanism and aiming to characterize restorative sleep through the lens of glymphatic clearance." In their quest for clues, she and her team investigated the effects of sleep on mice brains. Their primary focus was on the connection between norepinephrine levels and blood circulation during deep sleep phases. Researchers discovered that fluctuations in norepinephrine levels are linked to changes in brain blood volume, indicating that norepinephrine may initiate a rhythmic pulsation within the blood vessels. The researchers subsequently analyzed the relationship between variations in blood volume and the flow of fluid within the brain, discovering that fluctuations in brain fluid flow align with changes in blood volume. The blood vessels function as pumps, driving the adjacent brain fluid to remove waste materials. "Think of norepinephrine as the conductor of an orchestra," said Dr. Natalie Hauglund, the lead author of the study from the University of Copenhagen and the University of Oxford. "The rhythmic contraction and expansion of the arteries create a balance that propels the cerebro-spinal fluid through the brain, effectively eliminating waste materials." Dr. Hauglund subsequently inquired whether all types of sleep were essentially the same. In order to investigate, the research team administered zolpidem, a widely used sleep aid, to mice. Researchers discovered that the norepinephrine levels during deep sleep were reduced by 50% in mice treated with zolpidem compared to those sleeping naturally. While the zolpidem-treated mice did fall asleep more quickly, there was a significant decrease of over 30% in fluid transport into the brain. The researchers say their findings published in the journal Cell show that the sleeping pills likely disrupt the norepinephrine-driven waste clearance during sleep—and the findings probably apply to humans, as well, because also have a glymphatic system. Researchers have detected comparable patterns of norepinephrine waves, blood circulation, and cerebrospinal fluid movement in humans. “More and more people are using sleep medication, and it’s really important to know if that’s healthy sleep,” said Hauglund in a media release. “If people aren’t getting the full benefits of sleep, they should be aware of that, so they can make informed decisions.” Their research might also shed light on the ways in which inadequate sleep could play a role in the development of neurological conditions like Alzheimer’s. "With our understanding that norepinephrine plays a key role in the brain's cleansing process, we may be able to discover ways to promote longer and more restorative sleep for individuals," Professor Nedergaard concluded.

Gaining insights into the ocean floor may enhance our comprehension of weather patterns (Getty Stock Image) In my mind, I envision an enchanting grotto teeming with intriguing fish and vibrant underwater flora, but the truth is far more terrifying. Wright opened up about her experience in an op-ed written for the Los Angeles Times, in which she explained her plans to explore a previously unvisited area of the trench and use high-resolution sonar to create both an elevation model and a visualization that resembled an aerial photograph, But even before Wright left the ocean, she saw something sitting in the sediment at the bottom. It wasn't a fish, an aquatic plant, or even a long-lost shipwreck. It was a beer bottle. In her op-ed, Wright recalled: "It had traveled more than 6.7 miles to the darkest depths of the Pacific, label still intact. This discarded trash had managed to reach an unsullied part of our world before we actually did — a symbol of how deeply and irrevocably humans are affecting the natural world."

The oceanographer turned to social media to announce the discoveries (Twitter/@deepseadawn) The sobering acknowledgment that human activities have influenced every corner of the planet underscored for Wright the crucial role of mapping technology. This technology is essential for exploring every detail of the Earth, enabling us to comprehend not only the transformations taking place but also the consequences of those transformations. With the help of geographic information system (GIS) technology, Wright discussed mapping the entirety of the ocean in detail by 2030. She elaborated that gaining a comprehensive understanding of the ocean floor is crucial, as it will enable us to comprehend the ways in which heat moves through the water, and consequently, how this movement impacts the water above. Ultimately, this water will influence the atmosphere and weather patterns. Wright clarified that gaining a deeper understanding of how this heat circulates within the ocean will aid us in predicting when it contributes to the formation of hurricanes, which are intensifying due to climate change.

Exploring Cancer Immunotherapy: Understanding the Mechanisms of Therapeutic Antibodies

2025-03-29 21:22:02

View pictures in App save up to 80% data. In the field of medical research, an innovative advancement has emerged from the University of Würzburg's laboratories in Bavaria, Germany. The study led by Professor Markus Sauer and his team represents a significant progression in the comprehension and creation of therapeutic antibodies. This research sheds light on the complex interactions between antibodies and their target molecules, especially in relation to B cells linked to blood cancers, including chronic lymphocytic leukaemia. The research team has pioneered a cutting-edge super-resolution microscopy method called LLS-TDI-DNA-PAINT, which enables real-time visualization of therapeutic antibodies attaching to target proteins on cancer cells in three-dimensional space, achieving an unprecedented level of detail and precision. For many years, immunotherapeutic antibodies have played a crucial role in the treatment of different types of tumors. A key focus of these therapies is the CD20 protein found on the surface of B cells. The binding of these antibodies to CD20 triggers a series of immune responses that ultimately result in the elimination of cancerous cells. Nonetheless, even with the proven effectiveness of these antibodies in clinical settings, scientists have struggled to fully understand how they bind and the cellular responses that follow. Recent groundbreaking research from Würzburg has made significant strides in addressing this knowledge gap. Using the LLS-TDI-DNA-PAINT method, scientists successfully observed the real-time dynamics of therapeutic antibodies. They examined the interaction between these antibodies and CD20 molecules, focusing on how this binding affects the structural behavior of B cells during the process. A significant finding from the study was the observation of a phenotypic change in B cells, which the researchers referred to as adopting a “hedgehog shape.” This alteration occurs due to the crosslinking of CD20 proteins by the antibodies, which activates complement systems and enhances targeted immune responses. The researchers performed their observations utilizing the Raji B cell line, which is derived from human Burkitt's lymphoma and is well-regarded for its significance in cancer research. This specific cell line acts as a model for evaluating B cell responses to therapeutic antibodies. The research team executed experiments with four different therapeutic antibodies: RTX, OFA, OBZ, and 2H7, all of which are recognized for their targeting of CD20. The findings from their studies indicated that, irrespective of the antibody type used—whether categorized as type I or II—the response mechanism was remarkably similar, challenging earlier beliefs held by the scientific community. Additionally, research has demonstrated that therapeutic antibodies primarily bind to specific areas of the B cell membrane, particularly at microvilli. These tiny projections serve as crucial sites for protein interactions and contribute to the overall stability of the B cell surface during therapeutic applications. The noted polarization of B cells, alongside the reinforcement of microvilli, supports the idea that the structure of the cell membrane significantly influences immune responses. These insights not only clarify the processes involved in antibody binding but also suggest opportunities for enhancing therapeutic approaches by adjusting these interactions. An additional noteworthy feature of this research is the possible role of hedgehog-shaped B cells in enhancing inter-cellular communication within the immune system. The scientists suggest that this change in shape could be crucial for the development of immunological synapses, encouraging B cells to interact with macrophages and natural killer cells. This hypothesis expands on existing knowledge and highlights the urgent need for more investigations into how these activated B cells contribute to the coordination of larger immune responses. The introduction of the LLS-TDI-DNA-PAINT method marks a significant advancement in our ability to investigate therapeutic mechanisms at the molecular scale. This innovative technique lays the groundwork for future research focused on understanding the intricacies of cell-surface interactions and the complex processes that underpin immune recognition and the elimination of cancer cells. With this state-of-the-art visualization technology, scientists are empowered to examine the subtle nuances of antibody binding dynamics, creating an exceptional foundation for the development of tailored immunotherapy strategies. As the research advances, the team at the University of Würzburg aims to explore further the potential impacts of their discoveries on the future of antibody-driven cancer treatments. Thanks to the breakthroughs achieved with the LLS-TDI-DNA-PAINT method, there is an encouraging outlook where therapeutic antibodies can be customized and developed by directly analyzing their behavior within the tumor microenvironment. In conclusion, this pivotal study from Würzburg not only disputes current models in the therapeutic antibody sector but also highlights the transformative potential of advanced microscopy methods in reshaping our comprehension of cancer biology. As scientists persist in their investigations, the optimism for better therapeutic approaches and enhanced patient results is strong, serving as a source of inspiration in the relentless fight against blood cancers and other related diseases.
