The new pump has no moving parts. “Instead, it relies on thermoacoustics, the interaction between sound waves and heat, to move thermal energy,” Interesting Engineering writes. The pump uses that ...

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 ...

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, ...

Exotic states of matter known as time crystals are largely considered a quantum phenomenon. Now, a team from New York University (NYU) has shown that a classical time crystal can emerge in a far ...

A strange form of matter called a time crystal has fascinated physicists for about a decade. These systems move in repeating cycles, even without a steady external push.

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 ...

Using artificial intelligence (AI) and sound waves, researchers have found a possible means of looking inside stars. It’s based on the fact that stars aren’t solid objects — far from it, in fact. They ...

When exposed to stress and strain, materials can display a wide range of different properties. By using sound waves, scientists have begun to explore fundamental stress behaviors in a crystalline ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Engineers at Switzerland’s École Polytechnique Fédérale de ...

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 ...
