Light can behave in very unexpected ways when you squeeze it into small spaces. In a paper in the journal Science, Mark ...

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.

To get an idea of why making things spin with sound waves is difficult, picture a tube that holds a turbine. Normally, to make the turbine spin, a fluid would flow past the blades of the turbine.

Sound waves power ping-pong ball through aquatic obstacle course 'Wave momentum shaping' may offer a noninvasive method for guiding drugs inside human bodies. Andrew Paul Jun 26, 2024 12:01 PM EDT ...

For the first time, researchers were able to transmit, or "tunnel," sound waves across extremely small distances between two crystals in a vacuum. When you purchase through links on our site, we ...

But let us not confuse these sounds with the traditional sound waves we have on Earth. They can’t travel in the vacuum of space like they do on Earth; the cosmos is full of vibrations, radio ...
