Astronomers may have discovered an extreme pair of light-spewing black holes that are spiraling toward an enormous collision — the effects of which could be felt in the next century. Using decades of radio telescope observations, the astronomers studied an ultrabright object that was previously thought to be a blazar — a glowing core of a galaxy usually powered by a black hole — some 500 million light-years from our solar system. The observations revealed a hidden jet of energy that suggests the intensely bright object is actually two black holes on the verge of colliding, perhaps less than 100 years from now. https://www.sott.net/article/505799-Two-supermassive-black-holes-may-collide-100-years-from-now-and-Earth-would-feel-it Sat, 18 Apr 2026 15:22:31 +0000 https://www.sott.net/article/505793-Scientist-suggests-dark-matter-could-be-product-of-black-holes-from-a-different-universe Claims relic black holes from a pre-Big Bang 'bounce' solve the universe's biggest mystery While the scientific establishment has spent decades chasing invisible particles that never quite show up, a leading cosmologist has dropped a theory that turns everything on its head: dark matter isn't some exotic new particle. It could be ancient black holes that survived from an entirely different universe. This idea, laid out by Professor Enrique Gaztanaga of the University of Portsmouth, doesn't just tackle one cosmic puzzle. It offers a clean fix for the Big Bang's thorniest problems and lines up with fresh observations that have astronomers scrambling. Gaztanaga argues the elusive substance that makes up roughly 27 per cent of the universe's mass may actually be "relic" black holes formed in a previous collapsing phase of the cosmos. https://www.sott.net/article/505793-Scientist-suggests-dark-matter-could-be-product-of-black-holes-from-a-different-universe Fri, 17 Apr 2026 22:09:27 +0000 https://www.sott.net/article/505779-Neurobiologists-map-and-activate-brain-circuits-linked-to-placebo-pain-relief Researchers demonstrate that placebo pain relief generalizes across different types of pain, offering hope for opioid-free pain management strategies Placebo effects, in which patients experience relief without therapeutic treatment, increasingly have been considered as potentially powerful clinical treatments for ailments such as depression and pain. Yet the neurological mechanisms underlying such processes are not fully understood. Now, a multi-institutional team led by the University of California San Diego's Matthew Banghart, an associate professor in the School of Biological Sciences, has pinpointed the brain circuitry responsible for placebo pain relief. Their findings, reported in the journal Neuron, describe brain regions that support placebo effects and identify sites where endogenous opioid neuropeptides (commonly referred to as endorphins) provide signals that are critical for placebo pain relief. The study is the first to establish placebo mechanisms using a "reverse... https://www.sott.net/article/505779-Neurobiologists-map-and-activate-brain-circuits-linked-to-placebo-pain-relief Fri, 17 Apr 2026 15:30:01 +0000 https://www.sott.net/article/505751-The-deepening-mystery-of-the-March-fireballs If you love a good mystery, look no further than the night sky in March 2026. There were no major meteor showers scheduled for March, yet suddenly fireballs started appearing everywhere. "During the month of March, reports of very bright fireballs to the American Meteor Society (AMS) suddenly doubled," says Mike Hankey, who manages the AMS's fireball reporting system. "Many of them were visible in broad daylight and created loud sonic booms." A daytime fireball over Western Europe on March 8th drew more than 3,200 witness reports. Nine days later, a 7-ton asteroid exploded over Ohio with the force of 250 tons of TNT. On March 21st, a fireball broke apart above Houston, sending a fragment through the roof of a house. And those were just the headliners. Hankey has been running the fireball reporting system for nearly 15 years (indeed, he wrote much of the software himself), so he knew something unusual was happening. When the reports kept piling up, he dove into the data -- and what... https://www.sott.net/article/505751-The-deepening-mystery-of-the-March-fireballs Thu, 16 Apr 2026 03:32:59 +0000 https://www.sott.net/article/505733-Rubin-observatory-announces-11000-new-asteroids The Vera C. Rubin Observatory will discover up to half a million solar system objects every year. It's already starting to deliver on that promise. The Vera C. Rubin Observatory promised to discover up to half a million new solar system objects each year of operation. It isn't fully operational yet, and it's already delivering on that promise. Last week, the International Astronomical Union's Minor Planet Center confirmed the discovery of more than 11,000 new asteroids captured by Rubin during a 1½-month observation period. That period wasn't even part of its planned Legacy Survey of Space and Time (LSST), just a test run to check systems and optimize observations. Still, it was enough for Rubin's powerful 8.4-meter Simonyi Survey Telescope to make thousands of discoveries. While most of them are in the main asteroid belt, the list includes 380 trans-Neptunian objects (TNOs) that orbit beyond Neptune, and 33 previously unknown near-Earth objects. This latest submission to the Minor... https://www.sott.net/article/505733-Rubin-observatory-announces-11000-new-asteroids Wed, 15 Apr 2026 17:48:26 +0000 https://www.sott.net/article/505727-Tests-suggests-Googles-AI-Overviews-tell-millions-of-lies-per-hour Is 90 percent accuracy good enough for a search robot? Google doesn't much like this test. Google spokesperson Ned Adriance tells the Times that Google believes SimpleQA contains incorrect information. Its model evaluations often rely on a similar test called SimpleQA Verified, which uses a smaller set of questions that have been more thoroughly vetted. "This study has serious holes," Adriance told the Times. "It doesn't reflect what people are actually searching on Google." Benchmark problems Evaluating new AI models sometimes feels more like art than science, which is part of the problem. Every company has its own preferred way of demonstrating what a model can do, and the non-deterministic nature of gen AI can make it hard to verify anything. These robots can get a factual question right and then completely miss it if you rerun the query immediately. Oumi even uses AI tools to run its assessments, and those models can hallucinate, too. https://www.sott.net/article/505727-Tests-suggests-Googles-AI-Overviews-tell-millions-of-lies-per-hour Tue, 14 Apr 2026 21:58:16 +0000 https://www.sott.net/article/505719-Super-magma-reservoirs-discovered-beneath-Tuscany A Swiss-Italian team has discovered 6,000 km³ of magma beneath Tuscany. How can magma buried 5, 10, or even 15 km underground be detected without any surface indicators? The answer lies in ambient noise tomography, a technique that analyses natural ground vibrations with high precision. A team from the University of Geneva (UNIGE), the Institute of Geosciences and Earth Resources (CNR-IGG), and the National Institute of Geophysics and Volcanology (INGV) has identified a vast reservoir containing approximately 6,000 km3 of magma beneath Tuscany. Beyond its scientific significance, this breakthrough paves the way for faster and more cost-effective exploration methods to locate resources such as geothermal reservoirs, lithium, and rare earth elements, whose formation is closely linked to deep magmatic systems. The study was published in the journal Communications Earth & Environment.

They were looking at monthly temperature data in 819 locations across the US. Then they checked the cardiovascular death rates and found the burden of excess deaths is "quite substantial". During cold periods our blood vessels contract to reduce heat loss, which is why our skin looks slightly bluer or whiter in colder weather. But even a small reduction in volume makes our blood pressure rise. So it is not surprising that colder months are linked to significantly higher death rates from heart attacks, strokes, and coronary artery disease compared to milder periods. As the population ages and kidney disease and diabetes get worse, the Nearly every dollar we pour into preventing heat deaths will end up killing more people than it saves.

Researchers in the United States have unlocked secrets of high-temperature superconductors. Researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory have discovered how tiny changes in superhydride structure enable superconductivity at near room temperatures but extreme pressure — offering clues for designing more practical superconductors. "These experiments show what the upgraded APS can do. We can now study atomic-level structures with unprecedented detail in materials under extreme pressure," said Maddury Somayazulu, Argonne physicist. https://www.sott.net/article/505630-US-lab-unlocks-secrets-of-superconductors-that-ensure-no-energy-is-lost-during-electricity-flow Wed, 08 Apr 2026 21:59:05 +0000 https://www.sott.net/article/505600-Artemis-II-performs-closest-moon-flyby-amid-communication-loss The four astronauts of NASA's Artemis II mission have ventured farther from Earth than any humans before them. The Orion spacecraft, carrying three NASA astronauts and a Canadian Space Agency astronaut, performed its long-awaited lunar flyby, coming within roughly 4,070 miles (6,550 km) of the lunar surface and entering the Moon's gravitational sphere of influence. In a planned and highly anticipated phase of the journey, Mission Control in Houston lost contact with the crew at around 6:43pm ET for approximately 40 minutes. The communication blackout occurred as the Moon's body blocked radio and laser signals between the Earth-based Deep Space Network and the Orion spacecraft. While out of contact, NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with Canadian Space Agency (CSA) astronaut Jeremy Hansen, focused on their scientific objectives, photographing and observing the lunar far side - including the 600-mile-wide Orientale basin. https://www.sott.net/article/505600-Artemis-II-performs-closest-moon-flyby-amid-communication-loss Tue, 07 Apr 2026 20:25:21 +0000 https://www.sott.net/article/505593-Right-as-Artemis-II-astronauts-passed-behind-Moon-multiple-meteoroids-hit-it Artemis II were giddy (their words!) on the evening of April 6th when they witnessed explosions on the lunar surface. Meteoroids were hitting the Moon. "We saw at least five," reported mission commander Reid Wiseman. The meteors appeared in middle of a solar eclipse. About an hour after the crew made their closest approach to the farside of the Moon, the sun disappeared behind the lunar disk, giving the astronauts a chance to view the first solar eclipse ever seen by humans from behind the Moon. https://www.sott.net/article/505593-Right-as-Artemis-II-astronauts-passed-behind-Moon-multiple-meteoroids-hit-it Tue, 07 Apr 2026 07:46:52 +0000 https://www.sott.net/article/505590-The-most-pristine-star-yet-found-in-the-known-universe An unusual team of astronomers used Sloan Digital Sky Survey-V (SDSS-V) data and observations on the Magellan telescopes at Carnegie Science's Las Campanas Observatory in Chile to discover the most pristine star in the known universe, called SDSS J0715-7334. Their work is published in Nature Astronomy. Hunting for the universe's earliest stars Led by the University of Chicago's Alexander Ji — a former Carnegie Observatories postdoctoral fellow — and including Carnegie astrophysicist Juna Kollmeier — who leads SDSS, now in its fifth generation — the research team identified a star from just the second generation of celestial objects in the cosmos, which formed just a few billion years after the universe began. "These pristine stars are windows into the dawn of stars and galaxies in the universe," Ji explained. Several of his and Kollmeier's co-authors on the paper are undergraduate students from UChicago, whom Ji brought to Las Campanas on an observing trip for spring break last... https://www.sott.net/article/505590-The-most-pristine-star-yet-found-in-the-known-universe Mon, 06 Apr 2026 22:01:13 +0000 https://www.sott.net/article/505562-DNA-reveals-a-mysterious-human-lineage-no-one-knew-existed-in-Asia A genetic study has uncovered a previously unknown human lineage that survived the end of the last Ice Age, challenging long-held assumptions about how ancient populations evolved and interacted during one of the most transformative periods in human history. The discovery, published in the journal Current Biology, centers on ancient human remains unearthed at the Donghulin archaeological site near modern-day Beijing. By analyzing DNA extracted from these remains, scientists have revealed a complex and surprisingly resilient human story — one in which multiple lineages coexisted, adapted, and sometimes disappeared without leaving a lasting genetic trace. A Hidden Branch of Humanity Emerges At the heart of the discovery is an approximately 11,000-year-old individual whose genetic profile does not match any previously identified human population. Researchers, led by Qiaomei Fu, found that this individual belonged to a deeply divergent northern East Asian lineage that likely split from... https://www.sott.net/article/505562-DNA-reveals-a-mysterious-human-lineage-no-one-knew-existed-in-Asia Sun, 05 Apr 2026 17:50:02 +0000 https://www.sott.net/article/505558-Bumblebees-have-a-brain-the-size-of-a-sesame-seed-but-they-ve-still-got-rhythm Humans are creatures of rhythms. As far as we know, humans have always sung and always danced. We can recognise a song by its rhythm alone, regardless of whether it is played fast or slow. We seem to have an almost effortless capacity to pick up on rhythmic patterns, and we have presumed this ability to require the very large and powerful human brain. But our new research, published today in the journal Science, shows humans are not alone in mastering rhythm. Even the bumblebee, which has a brain the size of a sesame seed, has an ability to quickly learn abstract rhythms. A world full of rhythms Rhythms are everywhere in nature. We hear them in the songs of birds and frogs and the ultrasonic hunting chirps of bats. And we see them in the flashing displays of fireflies, the rhythmic shakes of a peacock's tail, the waggle dances of honey bees and the courtship dances of fruit flies. But, up to now, we have assumed these were innate rhythmic patterns: the animals are not learning a... https://www.sott.net/article/505558-Bumblebees-have-a-brain-the-size-of-a-sesame-seed-but-they-ve-still-got-rhythm Sat, 04 Apr 2026 23:04:48 +0000 https://www.sott.net/article/505551-Caltech-team-finds-useful-quantum-computers-could-be-built-with-as-few-as-10000-qubits Theoretical discovery opens the door to building quantum computers with significantly reduced resources. Quantum computers of the future may be closer to reality thanks to new research from Caltech and Oratomic, a Caltech-linked start-up company. Theorists and experimentalists teamed up to develop a new approach for reducing the errors that riddle today's rudimentary quantum computers. Whereas these machines were previously thought to require millions of qubits to work properly (qubits being the quantum equivalent to 1's and 0's in classical computers), the new results indicate that a fully realized quantum computer could be built with as few as 10,000 to 20,000 qubits. The need for fewer qubits means that quantum computers could, in theory, be operational by the end of the decade. The team proposes a new quantum error-correction architecture that is significantly more efficient than previous approaches. Quantum error correction is a process by which extra, redundant qubits are... https://www.sott.net/article/505551-Caltech-team-finds-useful-quantum-computers-could-be-built-with-as-few-as-10000-qubits Sat, 04 Apr 2026 20:08:35 +0000 https://www.sott.net/article/505539-Rare-sungrazer-comet-MAPS-will-shine-superbright-on-Saturday-if-it-survives-a-dangerous-encounter-with-our-star Comet C/2026 A1 (MAPS) could shine brightly in the evenings after April 4, but only if it survives a very close encounter with the sun. A rare "sungrazer" comet is about to pass very close to our star and could become visible in daylight — or it could completely disintegrate before our eyes. Either way, there could be something special to see in the night sky, with a large tail potentially visible late this week. Comet C/2026 A1 (MAPS) was discovered Jan. 13 by French astronomers at the AMACS1 Observatory in Chile. Although the comet was initially thought to have a nucleus measuring around 1.5 miles (2.4 kilometers) wide, astronomers later reduced the estimate to under 0.25 miles (0.4 km) based on James Webb Space Telescope observations taken in February. C/2026 A1 (MAPS) belongs to a special family of comets called Kreutz "sungrazers," so called because they get very close to the sun, lighting up brightly but often breaking into smaller pieces. There are around 3,500 members of... https://www.sott.net/article/505539-Rare-sungrazer-comet-MAPS-will-shine-superbright-on-Saturday-if-it-survives-a-dangerous-encounter-with-our-star Fri, 03 Apr 2026 22:02:07 +0000 https://www.sott.net/article/505530-Early-data-from-Vera-C-Rubin-Observatory-reveals-over-11000-new-asteroids Using preliminary data from the Vera C. Rubin Observatory, scientists have discovered over 11,000 new asteroids. The data were confirmed by the International Astronomical Union's Minor Planet Center (MPC), making this the largest single batch of asteroid discoveries submitted in the past year. The discoveries were made using data from Rubin's early optimization surveys and offer a powerful preview of the observatory's transformative impact on solar system science. The submission to MPC comprises approximately one million observations, taken over the span of a month and a half, of over 11,000 new asteroids and more than 80,000 already-known asteroids, including some that had previously been observed but were later "lost" because their orbits were too uncertain to predict their future locations.

Archaeologists in Vietnam have made a discovery that could rewrite scientists' understanding of where syphilis originated. The team found the Stone Age skeletons of three people who had a debilitating bacterial disease that left marks on their bones and teeth. This disease is in the same family as syphilis, and the discovery of it in prehistoric Vietnam could challenge the idea that syphilis-like diseases originated in the Americas. In a study published March 13 in the International Journal of Osteoarchaeology, the researchers documented three cases of congenital treponematosis at two Neolithic sites in Vietnam dating to around 4,100 to 3,300 years ago. Treponemal diseases are a group of infections caused by the bacterium Treponema pallidum. These diseases, caused by different subspecies of the bacterium, include syphilis, bejel and yaws.

New DNA evidence shows that the island was part of a dynamic world linking Europe, North Africa and even the Sahel zone, south of Sahara. An international research team led from the Centre for Palaeogenetics (CPG), a joint venture between Stockholm University and the Swedish Museum of Natural History, has revealed that its population was remarkably diverse, connected to Europe, North Africa, and sub-Saharan Africa through trade, migration, and social networks. The study is published in Nature Communications. By analysing ancient DNA from 13 individuals buried in a tenth- to twelfth-century Islamic cemetery, the researchers found a wide spectrum of genetic ancestries, ranging from predominantly European to predominantly North African. This reflects varying degrees of mixing following the Muslim conquest of Ibiza in 902 CE.

A new international study has examined how a reduction of the magnetic field similar to the Laschamps excursion would affect aviation on routes such as Helsinki-Dubai and Helsinki-New York if it occurred today. The magnetic field protects Earth from harmful cosmic radiation and solar eruptions. However, its strength slowly varies over time. Occasionally, the field can even reverse, meaning the magnetic north and south poles switch places. "The effects of a weakening and reversal of the magnetic field on the atmosphere and environment can be dramatic, yet still largely unknown. The consequences could be serious for our modern, highly technological society," says Professor Ilya Usoskin from the University of Oulu, who is a principal investigator of the prestigious large-scale ERC-funded GERACLE project.

Scientists based in Shanghai and Tianjin report that batteries built with the new hydrofluorocarbon-based electrolyte delivered more than twice the energy density of conventional designs when tested at room temperature. Beyond efficiency gains, the team says the chemistry remains stable in extreme environments, with batteries continuing to operate effectively at temperatures as low as minus 94 degrees Fahrenheit (minus 70 degrees Celsius). The development points to a potential path for longer-lasting, more resilient batteries suited for EVs and other demanding applications, where both energy density and reliability under stress are critical. https://www.sott.net/article/505460-Chinas-Breakthrough-Lithium-Battery-Could-Double-EV-Range-To-600-Miles-Survive-94F-Temp Tue, 31 Mar 2026 16:22:21 +0000 https://www.sott.net/article/505448-Mystery-medical-episode-that-left-astronaut-unable-to-speak-shows-one-of-NASAs-biggest-risks-for-extended-space-flight Veteran astronaut Michael Fincke's sudden medical emergency aboard the ISS is a stark reminder that, as NASA pushes toward long-term lunar missions, astronaut health remains one of spaceflight's biggest unknowns. As NASA prepares to send four astronauts around the moon for the 10-day Artemis II mission, a veteran space flier's unexplained illness in orbit is spotlighting one of the biggest risks of deep-space travel: the need for medical systems in case of emergencies. NASA astronaut Michael Fincke said a sudden episode aboard the International Space Station (ISS) in January left him unable to speak and forced NASA's first-ever medical evacuation from the orbiting laboratory. Doctors have ruled out a heart attack, Fincke told the Associated Press, but they still don't know what caused the medical issue. https://www.sott.net/article/505448-Mystery-medical-episode-that-left-astronaut-unable-to-speak-shows-one-of-NASAs-biggest-risks-for-extended-space-flight Mon, 30 Mar 2026 20:09:14 +0000 https://www.sott.net/article/505438-White-dwarf-discovered-gobbling-material-from-gamma-Cassiopeia Powerful X-rays from the nearby naked-eye star Gamma Cas mystified astronomers for decades. Now, a new observatory reveals that they come from its white dwarf companion. Some 550 light-years away, a bright star called Gamma Cassiopeiae is belching out bursts of X-rays. Now, astronomers have discovered that the radiation is actually coming from the star's invisible companion, which lights up in X-rays as it gobbles up material from the star. Gamma Cassiopeiae (Gamma Cas for short) is visible to the naked eye at 2nd magnitude, making up the center of the Cassiopeia constellation's distinctive "W" in northern skies. It's a variable star that's exhausting its supply of hydrogen, but it hasn't run out just yet. Unlike other stars like it, it emits X-rays. The star is surrounded by a gaseous disk, and for years, astronomers theorized that the emission was being produced either from the star's magnetic fields interacting with the disk, or perhaps from disk material falling onto an unseen... https://www.sott.net/article/505438-White-dwarf-discovered-gobbling-material-from-gamma-Cassiopeia Mon, 30 Mar 2026 16:26:22 +0000 https://www.sott.net/article/505436-China-Flexes-Robot-Wolves-With-Machine-Guns-And-A-Collective-Brain Four years of hyperdevelopment, battlefield testing, and deployment of FPVs, ground robots, AI-enabled kill chains, and soon humanoid robots have permanently altered the course of the modern battlefield, as war technologies once viewed as 2030s-era weapons are being pulled forward into the present day and are now proliferating across battlefields stretching from the Eastern European theater to the Gulf theater, as Eurasia appears to be at war. The latest reminder is that, regardless of the battlefield across Eurasia, there will increasingly be large swaths of land, miles deep, effectively forming a new kind of no-man's-land controlled by FPVs and ground robots operating with AI kill chains. In Ukraine, that no-go zone stretches 15 miles wide and already means a quick death for any biological soldier, with FPVs able to detect, track, and strike.

Recently published in the journal Physical Review Letters, the research shows how viscous liquids can suddenly break if stretched with enough force. The fracturing behavior suggests that viscosity — a liquid's resistance to flowing — may play a more prominent role in its mechanical properties than previously understood. It also raises new possibilities for how liquids might be manipulated in everything from hydraulics to 3D printers to blood vessels. "Our findings show that if pulled apart with enough force per area, a simple liquid — a liquid that flows — will reach what we call a point of 'critical stress," when it will actually fracture like a solid. And this is likely true for all simple liquids, including common examples, such as water and... https://www.sott.net/article/505430-Researchers-discover-the-breaking-point-where-liquids-can-be-made-to-fracture-like-solids Sun, 29 Mar 2026 22:36:52 +0000 https://www.sott.net/article/505425-Chinese-lander-reveals-giant-cavity-of-radiation-between-Earth-and-the-moon-It-could-change-how-lunar-exploration-is-done A new study using data from China's Chang'e-4 moon lander found an area of reduced radiation from cosmic rays near the moon. The findings could be used to improve the safety of lunar explorations. Could being a "morning person" improve your health ... on the moon? Scientists have identified what appears to be a "cavity" of reduced cosmic radiation near Earth's moon. The finding could help lower astronauts' exposure to harmful radiation on future lunar missions by timing some surface operations for local morning hours. The discovery, based on data from China's Chang'e-4 lunar lander, suggests Earth's magnetic field may affect distances in space farther than scientists previously expected. According to the researchers, the finding challenges the long-held assumption that galactic cosmic rays are roughly uniform throughout the space between Earth and the moon outside our planet's protective magnetic field.

Levels of CO2 at around 250 parts per million (ppm) were said to be lower than often assumed with just a 20 ppm movement recorded for the following near three million-year period. In addition, no changes in methane levels were seen in the entire period. Massive decreases in temperature with occasional interglacial rises appear to have occurred without troubling 'greenhouse' gas levels, and this revelation has caused near panic in activist circles. The assumed level three million years ago of CO2 was around 400 ppm, a convenient mark that has been used to explain the subsequent ice age and a drop to 250 ppm. Due to the recently published paper, this explanation has become more problematic and natural climate variation is correctly noted to have occurred with the... https://www.sott.net/article/505417-Shock-new-evidence-showing-no-link-between-CO2-and-temperature-over-last-three-million-years-stumps-net-zero-activists Sun, 29 Mar 2026 18:59:34 +0000 https://www.sott.net/article/505397-Comet-break-up-caught-action The Hubble Space Telescope caught a long-period comet breaking up just after it passed the Sun. The Hubble Space Telescope is more than 30 years old and has just one functional gyroscope left to steer it, yet the iconic observatory is still making incredible findings. Hubble has now caught a rare, close-up look at a comet that broke into several pieces during a close approach to the Sun. These observations have given us a unique front-row seat to the swan song of one of these icy wanderers. Caching this event required a good deal of luck. The team of researchers behind the finding originally requested time to observe a different comet — the brightest at the time — but it was moving too fast for Hubble to track. When telescope operators asked for a backup target, the team suggested C/2025 K1 (ATLAS) simply because the comet was in the right place at the right time. So when the researchers looked at the images, several days after they were taken, they were shocked to find five... https://www.sott.net/article/505397-Comet-break-up-caught-action Sat, 28 Mar 2026 17:31:15 +0000 https://www.sott.net/article/505395-Earth-is-facing-an-unexplained-surge-of-massive-booming-daytime-fireballs-in-early-2026 On a Saturday afternoon this past March, a piece of the solar system plummeted toward a home in north Houston. The one-ton space rock broke apart nearly 30 miles above the city, unleashing a violent sonic boom equivalent to 26 tons of TNT. A dark, jagged fragment smashed through a residential roof and even ricocheted around a bedroom like a cosmic pinball. This would have been stunning in itself, except there were more such meteor strikes. During the first three months of 2026, our planet waded through an unusually dense shooting gallery. The American Meteor Society (AMS) has tracked a staggering wave of large, bright meteors — known as fireballs — lighting up skies from California to Germany. Earth sweeps up tons of space dust every day. Usually, this material is the size of a grain of sand and burns up harmlessly in the upper atmosphere. But right now, we are colliding with much bigger rocks. And scientists are scrambling to figure out why.

The discovery could further the study of not only Earth's geology but also that of other bodies in our solar system. The key, according to work by associate research professor Gunther Kletetschka at the UAF Geophysical Institute, is in the greatly reduced level of natural remanent magnetization of rock that has been subjected to the intense forces from a meteor as it nears and then strikes the surface. Rocks unaltered by manmade or non-Earth forces have 2% to 3% natural remnant magnetization, meaning they consist of that quantity of magnetic mineral grains — usually magnetite or hematite or both. Kletetschka found that samples collected at the Santa Fe Impact Structure in New Mexico contained less than 0.1% magnetism. https://www.sott.net/article/505354-Scientist-reveals-cause-of-lost-magnetism-at-meteorite-site Thu, 26 Mar 2026 21:00:14 +0000 https://www.sott.net/article/505352-Large-new-crater-discovered-on-the-moon-Impact-likely-occurred-in-last-2-years A once-in-a-century crater formed on the moon right under our noses. A routine search of images from NASA's Lunar Reconnaissance Orbiter camera found a fresh crater as wide as two American football fields, planetary scientist Mark Robinson reported March 17 at the Lunar and Planetary Sciences Meeting in The Woodlands, Texas. The crater is 225 meters wide and formed in April or May 2024, Robinson said. According to predictions based on other lunar landmarks, a crater that big should form only once in 139 years. The discovery can help highlight the risks impacts pose to future astronauts. https://www.sott.net/article/505352-Large-new-crater-discovered-on-the-moon-Impact-likely-occurred-in-last-2-years Thu, 26 Mar 2026 20:30:44 +0000 https://www.sott.net/article/505346-Surviving-inside-a-tornado This scientist did by accident - he's lucky to be alive I have seen the center of a monster.

Introducing Comet Pan-STARRS (C/2025 R3): Michael Jaeger and Gerald Rhemann photographed the comet (magnitude +7.8) from Weißenkirchen, Austria: "The comet's brightness has increased significantly in recent weeks," they say. "One week after the full moon in April, it is expected to become visible to the naked eye." Discovered by the Pan-STARRS survey in Sept. 2025, the comet is diving toward its closest approach to the sun (0.50 AU) on April 19th, bringing it well inside the orbit of Venus. If current trends continue, the comet could brighten to magnitude +2, easily seen and photographed in the pre-dawn sky. https://www.sott.net/article/505342-Naked-eye-comet-on-the-way Thu, 26 Mar 2026 14:56:56 +0000 https://www.sott.net/article/505335-The-mystery-of-the-Ohio-and-Texas-fireballs Is Earth under siege? If you've been reading headlines about space rocks falling over Ohio and Texas, you might be wondering what's going on. According to NASA, it's nothing unusual, yet still a little mysterious. "Spring is fireball season," says Bill Cooke of the NASA Meteoroid Environment Office. "For reasons we don't fully understand, the rate of very bright meteors climbs 10% to 30% during weeks around the vernal equinox." The Ohio and Texas meteors landed squarely in the middle of the season. Onlookers saw the Ohio fireball on March 17th only 3 days before the equinox. The Texas fireball appeared one day after the equinox on March 21st. Both were visible in broad daylight, with sonic booms and meteorites. One fragment reportedly punched through the roof of a home in suburban Houston. "Meteorite falls--fragments that actually hit the ground--are more common in spring as well," says Cooke. https://www.sott.net/article/505335-The-mystery-of-the-Ohio-and-Texas-fireballs Wed, 25 Mar 2026 20:24:29 +0000 https://www.sott.net/article/505330-Data-centers-suspected-of-producing-mysterious-hum-heard-across-several-US-states Residents report vibrating homes and sleepless nights A mysterious humming noise has been reported in neighborhoods across several US states, rattling homes and leaving residents struggling to sleep. The latest reports come from Vineland, New Jersey, where locals say the sound began after construction started on a massive 2.5-million-square-foot data center, though officials have not confirmed a direct link. Residents say the constant noise is disrupting daily life. 'That is not construction, and that monstrosity is only partially built,' Scott Montgomery told ABC 6. 'It is infringing on our peace of mind and our tranquility.' Similar complaints have surfaced in parts of Virginia, home to hundreds of data centers, and in Connecticut earlier this year, though officials in those areas have yet to identify a confirmed source.

In a new study, Northwestern University scientists explored how snow flies — small, wingless insects that crawl across snow to find mates and lay eggs — survive in freezing cold temperatures. They discovered this snow-dwelling fly uses a surprising combination of strategies: it generates its own body heat like a mammal and produces antifreeze proteins like an Arctic fish. While sub-zero temperatures are a death sentence for most other insects, these adaptations allow snow flies to remain active at temperatures as low as -6 degrees Celsius (or 21.2 degrees Fahrenheit). The findings, published in the journal Current Biology, shed light on how life has adapted to survive in extreme environments and potentially could inform new strategies for protecting cells, tissues and materials from cold damage. https://www.sott.net/article/505329-Snow-flies-found-to-create-their-own-heat-plus-other-strategies-to-avoid-freezing Wed, 25 Mar 2026 19:14:46 +0000 https://www.sott.net/article/505287-High-school-student-invents-filter-that-eliminates-96-percent-of-microplastics-from-drinking-water Virginia teenager Mia Heller's filtration system harnesses the power of ferrofluid, a magnetic oil that binds to microplastics in flowing water A few years ago, teenager Mia Heller came across an article in her local newspaper about ongoing water quality issues in her neighborhood in Warrington, Virginia. Tests had revealed that the water available for daily consumption was highly contaminated with PFAS and microplastic pollution. The article further reported that government agencies would not be providing any funds for filtering the water. "It was up to people to provide their own filtration," says Heller. Not long after the article came out, Heller's parents invested in an advanced water filtration system at her home. The system, however, required constant upkeep. Seeing her mother replace the water filter membranes time and again, Heller set out to find a better solution. https://www.sott.net/article/505287-High-school-student-invents-filter-that-eliminates-96-percent-of-microplastics-from-drinking-water Mon, 23 Mar 2026 19:54:58 +0000 https://www.sott.net/article/505283-More-moons-for-Jupiter-and-Saturn-New-totals-here On March 16, 2026, the Minor Planet Center announced an additional 11 moons for Saturn, bringing its total to a whopping 285. Plus, Jupiter's moon count has finally cracked 100, with the addition of four newly discovered moons. Jupiter's grand total now stands at 101. The newly discovered moons are all quite small, at least as far as moons are concerned. That's why they haven't been discovered until now. These faint, distant space rocks are around 2 miles wide (3 km) with magnitudes of +25 to +27. The lower the number, the brighter it is. And truly bright objects even have negative numbers, like the sun (-26) and Venus (-4). So these moons are extraordinarily faint. They also orbit far from their planet, making them harder to track down. In fact, the moons of Saturn are so spread out, they span the width of about five full Earth moons as seen from our location here on Earth.

The way CO2 responds in ice cores is canon to "the faith" so this is more important than it seems at first glance. Believers are really struggling. Three million years ago the world was warmer, and about to cool into the violent ice age cycles. The ice core experts were expecting to confirm that CO2 levels were about 400ppm, as other proxies had shown, and they thought that greenhouse gases might fall and lead the cooling shift. But instead of CO2 being at 400 parts per million, and then leading the cooling, the bubbles trapped in ice were only 250 parts per million to start with and they stayed constant through important temperature swings. Sacre Bleu! CO2 did not appear to have any role in causing the warmth that was, or the cooling that followed. And nor did methane. O' the dilemma? Some sacred cows have to be sacrificed.

Of course we couldn't go investigate for ourselves, because as you will see below, there are 72 areas of Antarctica that only those with a special permit are allowed to enter.

Natural diamond, also called cubic diamond, has been considered the hardest natural material on Earth for so long that the Mohs hardness scale, which rates minerals' resistance to scratching, uses diamond as the scale's upper limit. It's called cubic diamond for its neat arrangements of carbon atoms in a cubic structure. In contrast, hexagonal diamond organizes carbon atoms in a lattice made of hexagons, like a honeycomb. https://www.sott.net/article/505199-Chinese-scientists-construct-rare-hexagonal-diamond-thats-harder-than-natural-diamond Tue, 17 Mar 2026 16:04:28 +0000 https://www.sott.net/article/505190-Earths-magnetic-field-during-solar-flare-January-2026 It seems improbable that a satellite designed to monitor polar ice sheets and floating sea ice could accurately measure a disturbance in Earth's magnetic field. But that is just what ESA's CryoSat mission did earlier this year. This is a story of unique innovation in satellite technology. At the end of last year, the CryoSat mission, which has been operating for almost 16 years, was given a remote upgrade of new software for its platform magnetometer. This instrument is installed on the satellite to ensure it orbits at the right altitude and directs its science instruments towards the right part of Earth's surface. The platform magnetometer is therefore an operational instrument and was not designed to produce scientific data about Earth's magnetic environment. https://www.sott.net/article/505190-Earths-magnetic-field-during-solar-flare-January-2026 Mon, 16 Mar 2026 22:02:29 +0000 https://www.sott.net/article/505147-Blackwater-lakes-and-rivers-in-the-Congo-Basin-are-emitting-ancient-carbon-into-the-atmosphere Blackwater lakes and rivers in the Congo Basin are releasing ancient carbon into the atmosphere, a new study shows. Previously, scientists thought this carbon was safely stored in the surrounding peatlands, but the research reveals that's not the case. The finding contradicts the long-held assumption that old peat carbon remains trapped underground, suggesting that some tropical peatlands could switch from being carbon sinks to major carbon sources. Comment: That's assumptions for you! If they'd been reading the Signs, they'd have noticed northern and Arctic peatlands 'catching fire', in winter, and made the connection to carbon/methane outgassing. "We are now faced with a 30-million-tonne question: we need to determine if this is just a small, natural leakage of ancient carbon, or the onset of broadscale destabilization," study lead author Travis Drake, a carbon biogeochemist at the Swiss Federal Institute of Technology Zurich (ETH Zurich), told Live Science in an email.

The international team of researchers, including scientists from The Australian National University (ANU), analyzed parrot feathers that were discovered at Pachacamac, Peru — one of the preeminent religious centers of the Andean civilization — far outside the birds' native rainforest range.

Miller is among a small but growing group of scientists who believe we should no longer think of cells as passive robots that automatically follow a code of instructions, carrying out orders from our genome like mindless drones. Instead, they say, the roughly 37 trillion cells that make up our own bodies are conscious — and that life and consciousness began at the same time.

When Crusaders and pilgrims returned to Europe in the Middle Ages, they spoke of the fearsome weapons wielded by their Muslim adversaries — especially their swords. Over time, Europeans named the mysterious metal from which these blades were forged: Damascus steel, after the ancient Syrian city.

Atmospheric CO2 is "higher than anything humans ever experienced" says Dr Phil Bierwirth, worried that current CO2 levels are beyond what we evolved to deal with, and 100% wrong. Poor Dr Bierworth obviously doesn't realize that even though atmospheric CO2 has risen from 320ppm to 420ppm, normal indoor CO2 levels are 500 to 1,000 ppm, and the air we breathe out is 40,000ppm.
