High on the Qinghai-Xizang Plateau, the ground stays frozen, with only the top few meters melting each summer. Although the region is warming about twice as fast as the global average, a new study finds that more than a third ...

In September 2024, Storm Boris brought extreme precipitation and severe flooding to large parts of Central and Eastern Europe. Poland, Czechia and Austria were particularly affected. In some areas, several hundred millimeters ...

Cells naturally send tiny packages to one another to share information. Researchers at Carnegie Mellon University have developed a simple, low-cost way to turn those packages into drug carriers that can deliver treatments ...

Chemical reactions have their own "impatient molecules." Unable to stay still even for a moment, they latch onto other molecules indiscriminately. Researchers have now found that even these molecules change where they "sit" ...

What happens to smoke particles after sunset can depend strongly on something as familiar as the amount of water in the air. New research from Md. Sohel Rana and Marcelo I. Guzman at the University of Kentucky shows that ...

For the first time, a team of physicists in the U.S. has clearly demonstrated a "helicon current drive" in a nuclear fusion experiment. Led by a team of Jeff Lestz, Robert Pinsker, and Bart Van Compernolle at General Atomics, ...

Around 121 million years ago, somewhere in modern northeastern China, an early bird took to the skies. If you drew its silhouette, you'd notice something was missing. Unlike any bird alive today, it had no tail feathers.

The Lycurgus Cup, a world-renowned 4th-century A.D. artifact housed in the British Museum, is constructed of "dichroic" glass that shifts from jade green in reflected light to ruby red in transmitted light. This means that ...

In humans, hunting is considered a man's endeavor. But in one of our closest living relatives, hunting is primarily women's business.

Bat populations across the United States face numerous threats, and one of the biggest may be the number of collisions with wind turbines. According to the most comprehensive study of the problem to date, published in the ...

Researchers in the U.S. and China have created a biocompatible, metal-free magnet that can be safely implanted and generate signals from deep inside the body. Led by Wubin Bai at the University of North Carolina, the team ...

Quantum networks, systems that connect devices using quantum mechanical effects, could potentially allow users to share information more securely and efficiently. Building these networks typically entails linking stationary ...
