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, ...

A study published last month by University of Minnesota mechanical engineering researchers has the potential to make waves – ultrasonic waves, to be exact – in fields like surgery and manufacturing. U ...

We may not have real hoverboards yet, but engineers have just invented a device that can levitate tiny objects using only the power of sound — a sonic tractor beam. Researchers say the technology ...
