It was a head-spinning discovery. In 2018, researchers in Japan claimed to find concrete evidence of an elusive particle, a ...

Chen Shen, assistant professor of mechanical engineering at Rowan University, uses acoustic science to spin and manipulate sound waves for micro applications including miniature robotics and new ...

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.

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 ...

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 ...

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 ...

Ultra high-frequency sound transmits energy through flesh and other materials that block light or heat used in conventional 3D printing. Stephen Shankland worked at CNET from 1998 to 2024 and wrote ...

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 ...
