In laboratories from Brazil to Munich, researchers are learning to grab matter with sound alone, sculpting ultrasonic waves ...

The acoustic properties of an ultracold fermion gas have been measured either side of the superfluid transition temperature in an experiment that has been described as “near perfect” and “beautiful”.

Helium leaks are hard to detect, since it is odorless, colorless, tasteless, and does not react with other chemical substances. In Applied Physics Letters, by AIP Publishing, researchers from Nanjing ...

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 ...

The magical acoustic secrets of a famous cave known as the "Devil's Church" have been revealed by researchers. The Devil's Cave, also known Pirunkirkko, is situated in the Koli mountain range in ...

Future wireless networks will need to process far more data across a wider range of frequencies than today’s systems. This ...

Save your breath: A new way to make bubbles requires only sound waves. Scientists made the bubbles in levitated drops of liquid, held aloft with sound waves. Tweaking the sound waves caused the ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Engineers at Switzerland’s École Polytechnique Fédérale de ...

"Second sound is the hallmark of superfluidity, but in ultracold gases so far you could only see it in this faint reflection of the density ripples that go along with it," study senior-author Martin ...

Video cameras continue to gain widespread use, but there are privacy and environmental limitations in how well they work. Acoustical waves are an alternative medium that may bypass those limitations.
