A study published last month by University of Minnesota mechanical engineering researchers has the potential to make waves – ultrasonic waves, to be exact – in fields like surgery and manufacturing. U ...

In laboratories from Brazil to Munich, researchers are learning to grab matter with sound alone, sculpting ultrasonic waves into invisible “hands” that can lift, push, and rotate objects without a ...

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

In 2018, Arthur Ashkin won the Nobel Prize in Physics for inventing optical tweezers: laser beams that can be used to manipulate microscopic particles. While useful for many biological applications, ...

We are surrounded by waves. tiny vibrational waves transport sound to our ears. Light waves stimulate the retinas of our eyes. Electromagnetic waves bring radio, television and endless streaming ...

Although their technique employs a method similar to laser trapping in biology, adaptable to a wider range of particle sizes and materials. The ability to move objects without touching them might ...

Alfredo has a PhD in Astrophysics and a Master's in Quantum Fields and Fundamental Forces from Imperial College London. Alfredo has a PhD in Astrophysics and a Master's in Quantum Fields and ...

3D printing typically involves depositing layers of molten plastic, laser-melting powdered metal, or using UV light to harden gelatinous resin. A new technique takes yet another approach, however, by ...

Researchers have created a microphone that listens with light instead of sound. Unlike traditional microphones, this visual microphone captures tiny vibrations on the surfaces of objects caused by ...

When an object in space appears to be racing at nineteen times the speed of sound, it instantly jumps from routine data point to global headline. The claim that NASA tracked such a hyperfast visitor ...

Tokyo, Japan - Researchers from Tokyo Metropolitan University have developed a new technology which allows non-contact manipulation of small objects using sound waves. They used a hemispherical array ...
