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 ...

A group of international researchers have developed a way to use sound to generate different types of wave patterns on the surface of water and use those patterns to precisely control and steer ...

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 ...

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 ...
