Supercell thunderstorms are known for their devastatingly gnarly tornadoes, but exactly how the twisters form is poorly understood. A new study suggests that scientists could glean hints with a little help from the cosmos. Muons, subatomic particles that are like heavy versions of electrons, could reveal the atmospheric pressure within a thunderstorm and resulting tornado,…
Unusually dry conditions and hurricane-force seasonal winds are fueling multiple fast-moving and destructive wildfires in Los Angeles County. Gusts that reached over 145 kilometers per hour (90 miles per hour) quickly drove the blazes into urban areas, forcing more than 100,000 people to evacuate from their homes and killing at least two people as of…

Dental analyses of ancient kangaroos reveal they weren’t such picky eaters as once thought, researchers report in the Jan. 10 Science. Instead, when it came to…
Recovery from PTSD comes with key changes in the brain’s memory system, a new study finds. These differences were found in the brains of 19 people who developed post-traumatic stress disorder after the 2015 terrorist attacks in Paris — and then recovered over the following years. The results, published January 8 in Science Advances, point…
