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.

Ultrasonic beams fired through a 3D-printed metasurface can create localized pockets of sound that are inaudible to ...

Researchers at MIT's Lincoln Laboratory are developing a highly pinpointed sound beam that can detect buried land mines from a safe distance. The new beam will use sound to seek out land mines like 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 ...

Open-ear audio is having a moment. JLab and Bose both have sunglasses that double as discreet headphones, but perhaps the most intriguing open-ear technology I’ve seen so far is the SoundBeamer, a ...

An acoustic “tractor beam” that can pull an object by firing sound waves at it has been created by physicists in the UK and US. The beam was made using a commercial ultrasound surgery system and ...
