Scientists have identified a giant new dinosaur from Brazil that reached about 20 meters long and lived 120 million years ago. Its surprising evolutionary ties to a Spanish dinosaur suggest its ancest…
The extinct “American cheetah” was not really a cheetah at all, but a puma relative with an unexpectedly flexible lifestyle. Fossils from the Yukon suggest northern populations survived partly by eati…
Physicists have directly observed a long-predicted quantum effect of gravity, putting one of Einstein’s foundational ideas to a striking new test. Using ultracold atoms, researchers split an atom’s qu…
Could math help explain why some relationships survive life’s inevitable stresses while others slowly fall apart? Researchers have spent decades developing mathematical models that treat romantic feel…
East Antarctica gained an astonishing 695 billion tons of ice between 2021 and 2023, temporarily slowing Antarctica’s long-term decline. Researchers found that warming thousands of miles away in the t…
MIT engineers have developed injectable “mini livers” designed to help support people whose failing livers can no longer perform essential jobs. Instead of replacing the damaged organ, the approach in…
A more realistic quantum model has revealed evidence that strange, nearly immobile quasiparticles called fractons could exist in solid materials. Their inability to move freely could make them promisi…
Hidden deep in the bush, ranging over huge territories at speeds humans can't match and through terrain not even the most rugged vehicle can handle, hyenas and lions are hard to study. Now, new resear…
