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 ...

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 ...

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 ...

Cancer is one of the leading causes of death in the U.S., second only to heart disease. But a new cancer treatment method from CU Boulder researchers uses sound waves to soften tumors and could be a ...

Optical neural networks may provide the high-speed and large-capacity solution necessary to tackle challenging computing tasks. However, tapping their full potential will require further advances. One ...

Scientists managed to significantly boost the production of green hydrogen using sound waves in a clean energy breakthrough. The "exciting" study combined high-frequency sound waves with less ...
