Acoustic metamaterials are a fast-evolving family of materials which manipulate sound waves in ever more advanced ways. Now, a team led by Changqing Xu at Nanjing Normal University in China has ...

New technology can knock down flames without water or harsh chemicals to help save your home from a fire. The secret? Sound ...

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 ...

Using sound waves instead of water to extinguish flames? This is not the stuff of science fiction but a new firefighting system being tested out by a fire department in Southern California.

Futuristic control of structure in some materials is being made possible by a physics loophole.

It’s a question I’m sure was keeping you up at night: can you make an object spin with a sound wave? The answer, generally speaking, used to be no. Now, though, mechanical engineers have taken a look ...

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.

Water has long been the go-to when it comes to fighting a fire. But what about sound waves? It might be hard to wrap your head around the concept at first, but the San Bernardino County Fire ...
