Scientists have begun to decipher the subtle signs that reveal how explosive a volcanic eruption is going to be.
Radioactivity May Fuel Life Deep Underground and Inside Other Worlds
New work suggests that the radiolytic splitting of water supports giant subsurface ecosystems of life on Earth — and could do it elsewhere, too.
The New Historian of the Smash That Made the Himalayas
About 60 million years ago, India plowed into Eurasia and pushed up the Himalayas. But when Lucía Pérez-Díaz reconstructed the event in detail, she found that its central mystery depended on a broken geological clock.
