MIT scientists have identified cysteine -- an amino acid found in foods like meat, dairy, beans, and nuts -- as a potent trigger for intestinal repair. In mice, a cysteine-rich diet activated immune cells that released healing signals, helping stem . ...

The French Riviera may look like an unlikely place for a tsunami disaster, but scientists warn the threat is far more real than most people realize. Historical events and new modeling show that destructive waves have already struck the Mediterranean ...

Reptiles have been growing armor in their skin on and off for hundreds of millions of years, but scientists never fully understood how it evolved. A massive new evolutionary study shows these skin bones appeared independently in multiple lizard ...

Scientists in Canada have discovered that ancient underground rocks are naturally producing hydrogen gas -- and lots of it. Measurements from mine boreholes in Ontario show the gas can flow continuously for years, offering a potential new source of . ...

Scientists have identified the oldest known human remains in Northern Britain as a young girl who lived around 11,000 years ago. Found in a Cumbrian cave and nicknamed the "Ossick Lass," she was likely between 2.5 and 3.5 years old when she died. ...

For decades, scientists believed ancient humans avoided dense rainforests, treating them as nearly impossible environments for early survival. But a groundbreaking discovery in West Africa is rewriting that story. Researchers uncovered evidence that ...

Scientists in Australia are using cutting-edge DNA techniques to help save one of the world's rarest marsupials -- the critically endangered Gilbert's potoroo, with fewer than 150 left in the wild. By analyzing tiny traces of DNA in the animals' scat ...

Why did T. rex have such tiny arms? Scientists now think it's because its giant head became the ultimate hunting tool. Across multiple dinosaur groups, stronger skulls and crushing jaws evolved alongside shrinking forelimbs, especially in predators . ...

Scientists have uncovered an astonishing new chapter in humpback whale migration: two whales were found to have traveled between breeding grounds in Australia and Brazil, crossing more than 14,000 kilometers of open ocean. One whale shattered records ...

A hidden network of earthquake faults running beneath Seattle may be far more active than scientists realized. New research reveals that smaller "secondary" faults in the Seattle Fault Zone appear to rupture roughly every 350 years -- much more often ...
