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.

A new startup is trying to scale up the idea of putting out fires using inaudible sound waves. Here & Now' s Peter O'Dowd speaks with Sonic Fire Tech co-founder and CEO Geoff Bruder about how the ...

Scientists at ETH Zurich and the Swiss Federal Institute of Technology Lausanne have developed a device that directs sound waves in one direction without wasting energy. This breakthrough sound wave ...

Gayle Anderson learns about Sonic Fire Tech, a startup company founded by former NASA engineers, that uses a patented ...

When [Electron Impressions] used a powerful ultrasonic array to project a narrow beam of sound toward a target, he described ...

Absorbing excess sound to make public environments like theaters and concert halls safer for hearing and using the unwanted sound waves to create electricity is the aim of a new paper. The authors ...

A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

On the rise. Signs of convection are seen in the motion of hot gas under the influence of a gravity-like acoustic force in a spherical glass container. The images were recorded 15, 40, and 140 ...

Cancer is one of the leading causes of death in the U.S., second only to heart disease. But a new cancer treatment method from CU Boulder researchers uses sound waves to soften tumors and could be a ...

The channel’s latest video demonstrates a gun that shoots a narrow beam of soundwaves, along with its most striking property: ...

At the start of my career, I used to do acoustic testing in an anechoic chamber where sound is not reflected as it gets absorbed. But the quietness of these chambers always got me thinking of how ...
