Researchers in Switzerland have found a way of using sound waves to manipulate objects in disordered environments such as liquids. Instead of trapping the objects as conventional optical and acoustic ...

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 ...

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 ...

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 ...

Although movie and game producers can now create computer-animated images of just about anything, the sounds made by those onscreen items still typically consist of recordings of real-world objects.

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 ...
