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.

Believe it or not, levitating objects aren't just the stuff of science fiction and magic shows. There are actually many different forms of levitation including something called acoustic levitation, ...

Acoustic levitation is some day going to be used to brush the dust off machinery on Mars. Learn why sound can lift objects off the ground and see an acoustic levitation chamber in action. “Sticks and ...

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 ...

An artist's rendering shows an acoustic hologram trapping a particle over a levitation device. Courtesy Asier Marzo, Bruce Drinkwater and Sriram Subramanian It's no Mattel hoverboard. But a device ...

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 ...
