In Yellowstone's wild chess match between wolves and cougars, it turns out the real power play is theft. After tracking nearly a decade of GPS data and thousands of kill sites, researchers found that wolves often muscle in on cougar kills--sometimes ...

When a bone break is too severe to heal on its own, surgeons often rely on grafts or rigid metal implants -- but both come with serious drawbacks. Now, researchers at ETH Zurich have created a jelly-like hydrogel that mimics the body's natural ...

Scientists have identified a crucial molecular switch that decides whether pancreatic cancer cells resist chemotherapy or respond to it. The key player, a gene called GATA6, keeps tumours in a more structured and treatable form--but it gets shut down ...

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.

Fusion energy may be one of the most promising clean power sources of the future--but only if scientists can precisely measure the extreme, fast-moving plasmas that make it possible. A new U.S. Department of Energy-sponsored report urges major ...

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 .. ...
