Earthquakes create ripple effects in Earth's upper atmosphere that can disrupt satellite communications and navigation systems we rely on. Nagoya University scientists and their collaborators have ...

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 ...

In context: Sound waves typically propagate in forward and backward directions. This natural movement is problematic in some situations where unwanted reflections cause interference or reduced ...

A team of scientists has succeeded in cooling traveling sound waves in wave-guides considerably further than has previously been possible using laser light. This achievement represents a significant ...

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 ...

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves. Water, ...
