For decades, scientists have mapped attention, memory, language, and reasoning to separate brain networks -- yet one big mystery remained: why does the mind feel like a single, unified system? Researchers at the University of Notre Dame now suggest . ...

A famously resilient bacterium may be tough enough to survive one of the most violent events imaginable on Mars. In laboratory experiments designed to mimic the crushing shock of a massive asteroid impact, researchers squeezed Deinococcus radiodurans ...

Astronomers using the James Webb Space Telescope have spotted the most distant "jellyfish galaxy" ever seen -- a cosmic oddity streaming long, tentacle-like trails of gas and newborn stars as it speeds through a dense galaxy cluster. The galaxy ...

Researchers at the University of Basel and the ETH in Zurich have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create adaptable electronic circuits with light.

Earth's vertebrate diversity may be far richer than anyone realized. A sweeping analysis of more than 300 studies suggests that for every known fish, bird, reptile, amphibian, or mammal species, there are about two nearly identical "cryptic" species ...

Tiny, tooth-sized fossils have just reshaped the story of our deepest ancestry. Paleontologists have discovered the southernmost remains ever found of Purgatorius--the earliest-known relative of all primates, including humans--in Colorado's Denver .. ...

Even in the ultra-dry Atacama Desert, tiny soil-dwelling nematodes are thriving in surprising diversity. Scientists found that biodiversity increases with moisture and altitude shapes which species survive. In the most extreme zones, many nematodes . ...

As millions turn to ChatGPT and other AI chatbots for therapy-style advice, new research from Brown University raises a serious red flag: even when instructed to act like trained therapists, these systems routinely break core ethical standards of ...

Polyamines--natural molecules found in every living cell--have become stars in the longevity world for their ability to boost cellular cleanup and support healthy aging. But there's a dark twist: high levels of these same molecules are consistently . ...

Icy moons circling the outer planets may be far more dynamic--and explosive--than they appear. New research suggests that when heat from tidal forces melts their ice shells from below, the sudden drop in pressure could cause hidden oceans to boil ...
