Hidden virus in your gut may be linked to colon cancer15:44 A newly discovered virus hiding inside a common gut bacterium could help explain one of medicine’s long-standing mysteries: why a microbe found in both healthy people and cancer patients is linked to colorectal cancer. The research suggests that the interaction between bacteria and the viruses they carry may be key to understanding disease risk. It may even lead to future screening tests that det… A simple blood test could reveal Alzheimer’s risk years early15:44 A routine blood marker tied to inflammation may reveal Alzheimer’s risk years in advance. Scientists found that higher neutrophil levels—part of the body’s first immune response—were linked to a greater chance of developing dementia. The discovery suggests this common lab value could help flag at-risk individuals before symptoms appear. It also raises the possibility that immune cells themselves … Ancient DNA reveals a lost population near Paris replaced by strangers15:44 Ancient DNA from a tomb near Paris reveals a shocking prehistoric reset: one population vanished and was replaced by newcomers from the south. The two groups show no genetic connection, signaling a major upheaval around 3000 BC. Disease, including early plague, likely played a role, but wasn’t the only cause. The change also reshaped society, ending tightly knit family burials and coinciding with… Scientists stunned as JWST finds ice clouds on a giant alien planet11:27 Scientists have discovered unexpected water-ice clouds on a distant, Jupiter-like exoplanet, challenging current atmospheric models. By directly imaging Epsilon Indi Ab with the James Webb Space Telescope, they found less ammonia than expected—likely hidden by thick, patchy clouds. The finding reveals new layers of complexity in giant planets and shows how much we still have to learn. DNA reveals a hidden pitviper species in China11:27 A vivid green pitviper hiding in Sichuan’s misty mountains has been revealed as a completely new species. Scientists had overlooked it for decades, assuming it was a common snake—until DNA analysis proved otherwise. Named after Laozi, it features striking differences between males and females, including bold stripes and eye colors. The discovery highlights just how many unknown species may still … Two common drugs may reverse fatty liver disease, study finds11:27 Scientists have discovered that combining two existing drugs can dramatically reduce liver fat linked to a common and often silent disease. The treatment not only improved liver health in animal models but also showed potential to lower heart-related risks. Interestingly, using lower doses of both drugs together worked just as well as higher doses alone. While promising, the findings still need t… “Baffling” new snake species in Myanmar looks like multiple species at once11:26 Scientists have uncovered a fascinating new species of pit viper in Myanmar that seems to blur the very definition of what a species is. This snake, now named the Ayeyarwady pit viper, puzzled researchers because it looks like a mix between two known species—sometimes resembling one, sometimes the other, and occasionally something in between. Initially suspected to be a hybrid, genetic analysis r… This “quantum” material fooled scientists and revealed something new11:26 A mysterious magnetic material once thought to host an exotic “quantum spin liquid” has turned out to be something entirely different—and possibly just as intriguing. Scientists studying cerium magnesium hexalluminate found it showed the hallmark signs of this elusive quantum state, like a lack of magnetic order and a spread of energy states. But after closer inspection using neutron experiments,… This donut-shaped discovery just shattered a 150-year math rule11:26 A 150-year-old rule in geometry has been proven wrong. Mathematicians found two different doughnut-shaped surfaces that look identical when measured locally but are actually different overall. For decades, researchers suspected this might be possible but couldn’t prove it—until now. The breakthrough reshapes how mathematicians understand the relationship between local measurements and global form. AI just revealed ocean currents we’ve never been able to see11:26 A new AI-driven method called GOFLOW is turning weather satellite images into highly detailed maps of ocean currents. By tracking how temperature patterns shift over time, it can reveal fast-moving, small-scale currents that were previously impossible to observe directly. These currents are key to understanding climate, marine ecosystems, and carbon storage. The breakthrough works using satellite… Ancient DNA reveals a hidden Neanderthal group frozen in time11:26 A remarkable genetic breakthrough has uncovered what may be one of the clearest snapshots yet of a Neanderthal “community” living together 100,000 years ago in what is now Poland. The findings reveal that these individuals shared genetic ties with Neanderthals spread across Europe and the Caucasus, hinting at widespread ancient lineages that later disappeared. A bizarre new state of matter may be hiding inside Uranus and Neptune21.dubna Deep inside planets like Uranus and Neptune, scientists may have uncovered a bizarre new state of matter where atoms behave in unexpected ways. Advanced simulations suggest that carbon and hydrogen, under crushing pressures and scorching temperatures, can form a strange hybrid phase—part solid, part fluid—where hydrogen atoms spiral through a rigid carbon framework. This unusual “superionic” stru… This new camera captures what happens in a trillionth of a second21.dubna Scientists have unveiled a breakthrough imaging method that can capture the hidden details of events unfolding in trillionths of a second. This new technique doesn’t just track how bright something is—it also reveals subtle structural changes that were previously invisible, all in a single shot. By effectively turning ultrafast phenomena into detailed “movies,” researchers can now watch plasma fo… Scientists just captured trees glowing with electricity during storms21.dubna Scientists chasing thunderstorms in a retrofitted minivan finally captured something never seen before in nature: faint electrical glows shimmering from treetops during a storm. These “corona discharges,” long suspected but never observed outside a lab, appeared as tiny UV flashes at the tips of leaves. The discovery could reshape how we understand forests, since these bursts may help clean the a… Scientists sculpt Einstein onto a crystal using only light21.dubna A light-sensitive crystal is opening the door to a new era of “light-written” technology. Arsenic trisulfide can be reshaped and permanently altered using simple light, creating ultra-fine optical patterns without expensive manufacturing tools. Scientists even etched a nanoscale portrait of Einstein and high-density patterns that could act as secure optical signatures. This breakthrough could pow… |
