Heat is not supposed to behave like this. In everyday life, warmth seeps and diffuses, spreading from hot to cold in a slow, smearing process that never looks anything like a crisp sound wave. Yet ...

“Second sound is the hallmark of superfluidity, but in ultracold gases so far you could only see it in this faint reflection ...

Sir Keir Starmer and Rachel Reeves, the Chancellor, are shown a heat pump. The units can produce a low hum of between 40 and 60 decibels - Jonathan Brady/PA Wire Noise restrictions on heat pumps are ...

Scientists at MIT have directly captured signs of “second sound” in a superfluid for the first time. This bizarre phenomenon occurs when heat moves like sound waves through an unusual state of matter.

Physicists at MIT have spotted the second sound of a superfluid. Besides being pleasantly alliterative, the phenomenon may explain how heat moves through certain rare materials on Earth and deep in ...

A record-shattering heat wave June 26-28 coincided with some of the year's lowest tides on Puget Sound. The combination was lethal for millions of mussels, clams, oysters, sand dollars, barnacles, sea ...

Researchers at the Chinese Academy of Sciences developed a thermoacoustic Stirling heat pump prototype that offers high thermal performance, a peak coefficient of performance of 1.68, and potential ...

The laws of physics—and thermodynamics in particular—are both a blessing and a curse for internal combustion-powered vehicles. Rapidly oxidized fuel results in gas expansion that drives the ...

SEATTLE — The heat wave peaked with temperatures in the low to mid-90s on Wednesday, with a high of 94 in Seattle. While the hottest weather is behind us in western Washington, Thursday will still be ...
