A tiny 242-million-year-old fossil from Devon is shaking up scientists' assumptions about the earliest members of the lizard lineage. Instead of the expected skull hinges and palate teeth typical of modern lizards and snakes, this ancient creature .. ...

Scientists have reconstructed the most complete and lifelike profile of Edmontosaurus annectens thanks to an extraordinary preservation process called clay templating, in which a thin clay film captured the dinosaur's skin, scales, spikes, and even . ...

Scientists found that RSV infection early in life can set the stage for childhood asthma, particularly in kids already genetically prone to allergies. The virus appears to skew the developing immune system toward exaggerated responses to everyday ...

Researchers studying thousands of canine genomes discovered that wolf DNA is still present in most dog breeds. This ancient genetic influence shows up in traits like body size, behavior, and environmental resilience. Even dogs bred far from wolves, . ...

The discovery of strange, ultra-red objects--especially the extreme case known as The Cliff--has pushed astronomers to propose an entirely new type of cosmic structure: black hole stars. These exotic hybrids could explain rapid black hole growth in . ...

Nearly a century after astronomers first proposed dark matter to explain the strange motions of galaxies, scientists may finally be catching a glimpse of it. A University of Tokyo researcher analyzing new data from NASA's Fermi Gamma-ray Space ...

ETH Zurich scientists have found the holy grail of brewing: the long-sought formula behind stable beer foam. Their research explains why different beers rely on different physical mechanisms to keep bubbles intact and why some foams last far longer . ...

Scientists have identified new anti-aging compounds produced by a little-studied blood bacterium. These indole metabolites were able to reduce inflammation, oxidative stress, and collagen-damaging activity in skin cell cultures. Three of the ...

Researchers found that repeated head impacts can disrupt a key system that helps the brain wash away waste. In professional fighters, this system initially seems to work harder after trauma, then declines over time. MRI scans revealed that these ...

A major review across 73 countries finds that access to antiseizure medications is rising, but safe prescribing isn't keeping pace. Valproate--linked to serious birth defects--remains widely used in many regions despite WHO warnings. Limited access . ...
