Forget superconductors and magnetic fields. Scientists from the University of Tokyo have developed a way to use sound waves to levitate objects and move them around midair. When a sound wave travels ...

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.

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 ...

What better way to start the day than by learning that yet another chunk of technology long envisioned by science fiction is on route to becoming science fact. Remember the tractor beam, that strange ...

Development for the tire industry has focused on minimizing friction between car and road. The key to high-speed concepts such as Hyperloop, is the elimination of friction in transportation. Which is ...

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 ...

Streams of sound are now all you need to make objects dance in the air and combine. A levitation device is the first to use high-frequency sound waves to bring together floating particles and liquid ...
