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 ...

Researchers have revealed how high-frequency sound waves can be used to build new materials, make smart nanoparticles and even deliver drugs to the lungs for painless, needle-free vaccinations. While ...

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 ...

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 ...

Three physicists from RIKEN have illustrated the ability of an ultrafast form of transmission electron microscopy to quantify sound waves in nanostructures. A cutaway of the ultrafast transmission ...

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.

Discover what goes on inside plants and learn the secret of sound waves. Join Steve Trash for a deep dive into the world of plants. Learn what goes on inside plants, how they turn sunlight into energy ...

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 ...

Sound waves have been part of science and medicine for decades, but the technologies have always relied on low frequencies. Now researchers have revealed how high frequency sound waves could ...
