A fanged frog long thought to be one species is revealing itself to be several
When a new species is discovered, it’s tempting to imagine an adventure novel, said Chan Kin Onn of Michigan State University. “Most people have this image of an intrepid explorer braving an isolated mountain or some other remote place, and…

What snow monkeys’ steamy baths are really doing to their bodies
Japanese macaques, better known as snow monkeys, are famous for sitting in steaming hot springs when temperatures drop. While the warm water clearly helps them cope with winter cold, researchers at Kyoto University found that these baths do more…

Life Rebounded “Astoundingly” Fast After the Dinosaur-Killing Asteroid, Study Finds
Helium-3 dating reveals new plankton species emerged within thousands—and sometimes just 2,000—years after the dinosaur-killing impact, showing life recovered far faster than assumed. Sixty-six million years ago, a massive asteroid collision…

Discovery of natural mechanism behind ferroptosis solves longstanding puzzle in cell biology
After more than a decade of research, scientists have discovered the natural mechanism behind a novel form of cell death called ferroptosis. The work, described in the current issue of Cell, points toward an entirely new strategy for treating…

The key to attacking 'undruggable' proteins: Transient clustering state reveals a moving target
Intrinsically disordered proteins lack a fixed structure, which is why they have been considered “undruggable” targets for drug development for years. However, these proteins play a key role in numerous diseases—ranging from various types of…

How an underground fungal map of the world's oldest, slowest-growing rainforest trees can boost Earth's resilience
The temperate rainforests of the Chilean Coast Range are home to a spectacular array of life: iridescent blue lizards, tiny wild cats called kodkods, and curly vines of waxy red bellflowers. Towering over this biodiversity are endangered ancient…
