A strange form of matter called a time crystal has fascinated physicists for about a decade. These systems move in repeating ...

A new University of Mississippi study shows that some sound waves don't just move forward—they also move slightly to the side. Understanding this movement could help researchers develop more precise ...

Hey all! So all my life I have heard that sound is a type of wave. This seemed to make sense to me. Recently I have come across some information that has me second guessing such tradition knowledge.

A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both rotation and orbital angular momentum ...

For the first time in half a century, a new class of sound wave has been developed. Acoustics experts from RMIT University in Melbourne, Australia are responsible for creating the wave, and it is set ...

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 ...

It’s a question I’m sure was keeping you up at night: can you make an object spin with a sound wave? The answer, generally speaking, used to be no. Now, though, mechanical engineers have taken a look ...
