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 ...

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

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.

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.

In the context of sensory modalities, eyes work like tiny antennae, picking up light, electromagnetic waves traveling at blistering speeds. When humans look at the world, their eyes catch these waves ...

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

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 ...

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 ...

Be it water, light or sound: waves usually propagate in the same way forwards as in the backward direction. As a consequence, when we are speaking to someone standing some distance away from us, that ...
