Phys.org / Embrace chaos to get lifelike movement from synthetic materials, researchers say

When people think of high-powered machines, they'd likely think of muscle cars before their own muscles. But muscles and other living tissues can do energetic things very quickly—they twitch, snap and beat—which is how ...

Phys.org / Scientists discover how plant cell walls guide stem cells

Imagine if our bodies could grow new organs throughout our entire lives. Plants do this constantly, thanks to tiny, powerful reservoirs of stem cells. But how do these cells know when to divide, and how do they ensure each ...

Phys.org / AI and underwater recordings reveal bowhead whale breeding grounds in Arctic sea ice

If bowhead whales produce particularly varied and diverse calls in one area, it is very likely that the area is a breeding ground. The species occurs exclusively in the Arctic Ocean and is therefore endemic to this region.

Phys.org / Signature of climate change: Nearly half of harmful wildfire smoke exposure linked to human-caused warming

Across the western U.S., wildfires and the dangerous smoke that results have increased in frequency and intensity since the 1990s—that much is clear. Surprisingly less clear are the exact reasons why: While greenhouse gas-related ...
