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 ...

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 ...

Researchers have come up with a new and improved way to levitate objects using sound waves alone, an impressive feat of mixed-reality technology that could pave the way for some seriously futuristic ...

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 ...

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, ...
