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 ...

Time crystals, a collection of particles that "tick"—or move back and forth in repeating cycles—were first theorized and then ...

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, ...

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 ...

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 ...

Researchers develop an innovative sound wave sensor to quickly and accurately detect elusive helium gas leaks, enhancing ...

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 ...

Inspired by the functioning of pulsed lasers, scientists from France and Japan have developed an acoustic counterpart that enables the precise and controlled transmission of single electrons between ...
