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 ...

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 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 ...

Using sound to levitate something when there are other objects in the way has been shown for the first time by UCL researchers and could lead to advances in the manufacturing and entertainment sectors ...

Ultrasonic sound waves have been used to levitate objects in crowded rooms to make hologram-like displays. Such acoustic levitation was previously only practical in empty spaces, but a new algorithm ...
