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 ...

It may seem straight out of "Star Trek," but it's real: Scientists have created a sonic "tractor beam" that can pull, push and pirouette objects that levitate in thin air. The sonic tractor beam ...

Tractor beams have hit the big time. A newly constructed device generates a beam of concentrated sound that, for the first time, exerts a continuous, perceptible tug on objects large enough to see.

A metamaterial is a composite material that exhibits unique properties due to its structure, and now researchers have used one featuring a small sawtooth pattern on its surface to move and position ...

We may not have real hoverboards yet, but engineers have just invented a device that can levitate tiny objects using only the power of sound — a sonic tractor beam. Researchers say the technology ...

Scientists at the University of Tokyo and the Nagoya Institute of Technology were recently able to levitate small items in three dimensions using only sound waves. While it's not uncommon for sound ...

It may seem straight out of “Star Trek,” but it’s real: Scientists have created a sonic “tractor beam” that can pull, push and pirouette objects that levitate in thin air. The sonic tractor beam ...
