Phys.org / The ice on Greenland is acting strangely: Scientists believe they finally know why

Deep inside the Greenland ice sheet are giant swirling plume-like structures. These have puzzled scientists for over a decade, but UiB researchers now believe they have cracked the mystery by applying the same mathematics ...

Tech Xplore / Exposing biases, moods, personalities and abstract concepts hidden in large language models

By now, ChatGPT, Claude, and other large language models have accumulated so much human knowledge that they're far from simple answer-generators; they can also express abstract concepts, such as certain tones, personalities, ...

Phys.org / Novel bacteria discovered in Florida's stranded pygmy sperm whales

Pygmy sperm whales (Kogia breviceps) are among the ocean's most enigmatic inhabitants—rarely seen and largely unstudied. They live far offshore in small groups, diving in search of squid and fish. Their quiet behavior and ...

Phys.org / Warming winters are disrupting the hidden world of fungi—the result can shift mountain grasslands to scrub

When you look out across a snowy winter landscape, it might seem like nature is fast asleep. Yet, under the surface, tiny organisms are hard at work, consuming the previous year's dead plant material and other organic matter.

Phys.org / 'Boomerang' earthquake simulations suggest ricocheting ruptures may be more common than previously thought

An earthquake typically sets off ruptures that ripple out from its underground origins. But on rare occasions, seismologists have observed quakes that reverse course, further shaking up areas that they passed through only ...

Medical Xpress / Will probiotics work for you? Models map gut metabolism to predict success

A new study demonstrates that computer models of gut metabolism can predict which probiotics will successfully establish themselves in a person's gut and how different prebiotics affect production of health-promoting short-chain ...

Phys.org / Particles don't always go with the flow (and why that matters)

It is commonly assumed that tiny particles just go with the flow as they make their way through soil, biological tissue, and other complex materials. But a team of Yale researchers led by Professor Amir Pahlavan shows that ...

Phys.org / Archaeologists identify elders in Iron Age Israel through household artifacts

A new study from Bar-Ilan University is shedding light on a long-overlooked social group in archaeology: the elderly. While research on women and children has flourished in recent decades, older adults have remained largely ...

Medical Xpress / Blood test 'clocks' can predict when Alzheimer's symptoms will start

Researchers at Washington University School of Medicine in St. Louis have developed a method to predict when someone is likely to develop symptoms of Alzheimer's disease using a single blood test. In a study published in ...

Phys.org / Global study finds smaller fish and shifting food webs despite stable species numbers

Species numbers alone do not fully capture how ecosystems are changing. In a global study, scientists analyzed long-term data from nearly 15,000 marine and freshwater fish communities. They found that fish food webs have ...

Phys.org / Why Triceratops has such a big nose: The first comprehensive hypothesis on soft tissue in the dinosaur

Triceratops and similar horned dinosaurs had unusually large nasal cavities compared to most animals. Researchers, including those from the University of Tokyo, used CT scans of fossilized Triceratops skulls and compared ...

Medical Xpress / Scientists find a mechanism showing how exercise protects the brain

Researchers at UC San Francisco have discovered a mechanism that could explain how exercise improves cognition by shoring up the brain's protective barrier. With age, the network of blood vessels—called the blood–brain ...
