Time crystals, a collection of particles that "tick"—or move back and forth in repeating cycles—were first theorized and then ...

Sound is usually treated as the most familiar of physical phenomena, the background noise of daily life rather than a frontier of fundamental physics. Yet in laboratories around the world, carefully ...

In a new study, Japanese researchers found that acoustic sound waves can influence how our cells behave -- including halting fat development. Forget fad diets and sketchy supplements, your favorite ...

A strange form of matter called a time crystal has fascinated physicists for about a decade. These systems move in repeating ...

In the ETH experiment, self-oscillations (blue-red) cause sound waves (green, orange, violet) to travel through the circulator only in one direction. Credit: Xin Zou Researchers at ETH Zurich have ...

Soil is one of our most precious resources. Ecoacoustics, or the study of environmental sounds, has been around for a century, but it has only recently been applied to understanding soils. This ...

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 ...

Researchers develop an innovative sound wave sensor to quickly and accurately detect elusive helium gas leaks, enhancing ...

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 ...
