Mount Etna breaks volcano rules, tapping 80-kilometer-deep magma in a rare fourth category of eruption

Located in Sicily, Mount Etna is Europe's most active volcano. Yet its origin remains largely enigmatic, as no existing geological model fully explains how it formed. In a new study, scientists from the University of Lausanne ...

This nasal spray rewinds the aging brain, restoring memory and reversing inflammation in preclinical models

Picture this: your brain is a high-performance engine. Over decades, it doesn't just wear down, it also starts to run hot. Tiny "fires" of inflammation smolder deep within the brain's memory center, creating a persistent ...

Cracking a 16-year proton mystery as ultra-precise hydrogen measurements confirm a smaller-than-expected core

The simplicity of a hydrogen atom makes it an ideal model for studying atomic structure and interactions. Yet, despite the fact that its simplest form consists of only one proton and one electron, physicists have had a hard ...

Yellowstone's magma source may be closer than thought, reshaping hazard models

Supereruptions are extremely large volcanic eruptions that eject more than 1,000 cubic kilometers of magma, rock and ash. They are among the most hazardous geological events on Earth and have profound impacts on the environment, ...
