Scientists find that “perfect” systems may be surprisingly fragile
Complex systems may work better when their parts are not perfectly alike. Northwestern physicists found that carefully balanced variation, or “disorder,” can make networks such as power grids, ecosystems, neurons, and materials more stable. Even random differences sometimes improved stability compared with completely uniform systems. The discovery could help researchers design more resilient technologies and explain why natural systems are so rarely perfectly uniform.
New chemical wipes out 95% of termites without harming humans
A chemical that stops drywood termites from building new exoskeletons killed about 95% of colonies in testing, offering a potentially safer alternative to traditional fumigation. Because termites eventually have no choice but to molt, the treatment turns a normal stage of their life cycle into a fatal weakness.
Scientists solve a 50-year mystery and discover a new human blood group
Scientists have identified the genetic cause behind the mysterious AnWj blood group antigen, solving a puzzle that began in 1972 and establishing a new blood group system called MAL. The discovery could make it much easier to find extremely rare AnWj-negative patients and donors and protect them from potentially dangerous transfusion reactions.
Hidden gut defect that may explain why IBD keeps coming back
Researchers have uncovered a hidden molecular warning sign of inflammatory bowel disease (IBD) that can linger even when patients feel well and appear to be in remission. By studying around 900 human gut biopsies and patient-derived mini-intestines, the team found that intestinal cells can remain unusually primed to die, creating a “smoldering” defect that may help drive future flare-ups.
This tiny organism can shrink to one quarter its size in milliseconds
A single-celled organism can shrink to one-quarter of its length in milliseconds using a remarkable calcium-powered protein “fishnet.” Scientists hope its unusual machinery could inspire artificial muscles capable of moving far faster than today’s designs.
This deep-sea enzyme survives heat that destroys most proteins
A deep-sea microbe uses an exceptionally heat-resistant enzyme to turn atmospheric nitrogen into ammonia at temperatures that would destroy most proteins. Its unusual structure and a newly observed reaction state may reveal an ancient, shared mechanism behind nitrogen fixation and could eventually inspire cleaner biotechnology and fertilizer production.
Scientists discover the first diplodocus ever found outside North America
A 150-million-year-old dinosaur fossil from Spain has been identified as the first confirmed Diplodocus ever found outside North America. The giant sauropod measured about 25 meters long and was preserved well enough for researchers to match distinctive features in its tail bones to the famous genus. Its unexpected appearance in Europe suggests dinosaurs were moving between the continents during the Late Jurassic, possibly across temporary land connections.
Billions in rare earth elements may be hiding in America’s coal ash
Scientists are looking to diatoms, sea sponges, and plants for a cleaner way to recover rare earth elements and other valuable minerals hidden inside coal ash, red mud, and mine tailings. The bio-inspired approach could turn massive industrial waste piles into useful materials while reducing energy use, harsh chemicals, and reliance on new mining.
Caltech’s tiny new chip can steer light in 74 quadrillionths of a second
A new Caltech device can redirect a beam of light in just 74 femtoseconds using another beam and a nanoscale silicon metasurface. The breakthrough could pave the way for dramatically faster photonic communications, computing, and sensing technologies.
Scientists just named a new snake after Guns N’ Roses legend Slash
A newly discovered snake from New Guinea has been named after Guns N’ Roses guitarist Slash, who has loved reptiles since childhood. Genetic testing and physical differences confirmed that the reddish-brown groundsnake, Lielaphis slashi, is a species scientists had never formally recognized before. The nonvenomous snake may use large rear teeth to catch slippery lizards and reptile eggs.
Scientists are about to test Einstein’s gravity with exotic matter
Scientists have found a new way to create a controlled beam of muonium, an exotic atom containing a heavier cousin of the electron. The advance could allow researchers to test for the first time whether gravity acts on second-generation particles exactly as Einstein’s theory predicts. Any unexpected difference would be a major surprise and could potentially point toward new physics, including a hypothetical fifth force.
NASA’s Roman Space Telescope could last more than twice as long as planned
NASA’s Roman Space Telescope may now have enough fuel for at least 22 years of science, more than double its original 10 year design life. An extremely precise course correction, extra fuel at launch, and additional expected savings could keep the powerful observatory studying the universe for decades.
Scientists discover cells that cheat death and rebuild damaged tissue
Scientists discovered a population of cells that can start the process of programmed cell death, survive it, and then help rapidly rebuild damaged tissue. Their descendants become far more resistant to future damage, revealing a mechanism that could improve healing but may also help cancers return after treatment.
Scientists restore a brain protein and reverse signs of aging in mice
Scientists found that declining levels of the brain protein Menin may help drive aging, with lower levels in mice linked to inflammation, cognitive decline, weaker bones, and thinner skin. Restoring Menin reversed several age-related changes, while the amino acid D-serine improved cognition, hinting at a potentially intriguing new target for healthy aging.
These blood thinners may have an unexpected benefit for Alzheimer’s patients
Newer blood thinners may do more than prevent strokes in people with Alzheimer’s disease and atrial fibrillation. Researchers found that patients taking NOACs experienced a slower decline in cognitive function than those using warfarin or no blood thinners. The effect was modest each year but could add up over time.
Ozempic can change your body. Can it change your life?
Ozempic and other GLP-1 medications can improve blood sugar, weight, and cardiovascular health, but researchers found little evidence that they also improve mental health, employment, marriage, or overall well-being. The findings suggest the drugs’ broader life effects may be subtler than their dramatic physical health benefits.
Anak Krakatau blasts ash nearly 10 miles high
Anak Krakatau erupted for more than 24 hours in early September, sending volcanic ash up to 50,000 feet into the atmosphere. The ash cloud shut down eight airports, disrupted nearly 3,000 flights, and affected air quality as far away as Jakarta. NASA satellites captured dramatic views of the plume spreading across the region.
NASA’s Moon orbiter finds a 728-foot crater that wasn’t there before
NASA’s Lunar Reconnaissance Orbiter has revealed a 728-foot-wide crater that formed on the Moon in 2024, making it the largest newly formed crater ever identified in the solar system. The impact disturbed the surface for miles around it, creating a surprisingly large cold zone and showing how dramatically a single collision can reshape the lunar landscape.
Scientists just discovered why Arctic sea ice moves so strangely
Arctic sea ice may move in unexpected ways because individual ice floes are constantly colliding and transferring energy. Researchers found that this simple process can explain several long-standing mysteries about how quickly the ice moves and spreads.
This popular fermented food may help flush nanoplastics from the body
A kimchi-derived bacterium can bind to nanoplastics under gut-like conditions and may help carry them out of the body. In mice, the probiotic more than doubled the amount of nanoplastics detected in feces, pointing to a surprising potential use for microbes from fermented foods.
Scientists discover a mysterious new frog hiding in the Amazon
Scientists discovered a new frog species in the flooded forests of the western Amazon, distinguishing it from nearly identical relatives through DNA and its unique call. Adenomera varcena highlights how much Amazonian biodiversity remains hidden even as habitat loss and climate change threaten these poorly understood species.
A $100 detector can see invisible particles raining down from space
A pocket-sized, roughly $100 detector can reveal the invisible stream of cosmic particles constantly passing through Earth and even through our bodies. What began as a student physics project is now being used in major experiments, balloon missions, and potentially future spacecraft.
Astronomers just found the youngest known planet ever
Astronomers have confirmed a Jupiter-size planet less than a million years old, making Elias 2-24 b the youngest known planet and giving scientists a rare look at a world still being born. Its surprisingly rapid formation challenges leading theories about how giant planets come together, especially so far from their stars.
JWST’s mysterious little red dots may be black holes growing at incredible speeds
New supercomputer simulations suggest JWST’s puzzling Little Red Dots are rapidly growing black holes from the early Universe. Extreme radiation may have helped create unusually massive black hole seeds, while dense surrounding gas allowed them to grow dozens of times faster than black holes can today. The simulated objects closely resemble the Little Red Dots seen by Webb. If correct, they could solve the mystery of how enormous black holes formed so soon after the Big Bang.
Scientists find a natural gut compound that helps heal the intestine
A natural compound produced by gut bacteria after digesting foods such as pomegranates, walnuts, and berries may help repair and protect the intestinal lining. The discovery reveals a surprising beneficial side of an inflammatory pathway and could inspire more targeted treatments for Crohn’s disease and ulcerative colitis.
Textbooks may have misdrawn this basic brain structure for 100 years
Scientists discovered that brain-cell axons may not be smooth tubes as textbooks have shown for more than a century, but instead naturally resemble strings of tiny pearls. Those pearl-like structures can change with neural activity and may help control how quickly electrical signals travel through the brain.
NASA’s New Horizons spots signs of liquid nitrogen flowing on Pluto
Scientists have found the first evidence that liquid may have flowed across Pluto’s surface in the recent past. Dark features on the enormous Sputnik Planitia glacier appear consistent with liquid nitrogen rising through cracks from deep beneath the ice. Computer models show that nitrogen could melt at the glacier’s base and travel upward like fluid through small conduits. The finding reveals that Pluto may be much more geologically active than its frozen appearance suggests.
Scientists find a hidden health advantage in black and green rice
Scientists found that black and green Japanese rice contain unusual, potentially beneficial fats and may be digested more slowly than ordinary white rice. The combination could make these colorful varieties promising ingredients for foods designed to support blood sugar and metabolic health.
New mesothelioma drug turns cancer’s own defenses against it
Scientists are testing a counterintuitive way to fight mesothelioma, an aggressive asbestos-linked cancer with few effective treatments. A new experimental mesothelioma drug kills cancer cells by disabling PRX3, an antioxidant defense that tumors use to survive intense oxidative stress. In an early clinical trial, it controlled disease progression in 67% of patients and produced encouraging survival results, raising hopes that the strategy could eventually be used against other cancers.
