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.
Scientists have been able to use the power of sound to levitate small items — including insects and fish — for decades. But now researchers in Switzerland have figured out how to move objects around ...
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 ...
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, ...
Researchers have come up with a new and improved way to levitate objects using sound waves alone, an impressive feat of mixed-reality technology that could pave the way for some seriously futuristic ...
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 ...

Hold on to your wand, Harry Potter: Science has outdone even your best "Leviosa!" levitation spell. Researchers report that they have levitated objects with sound waves, and moved those objects around ...
A metamaterial is a composite material that exhibits unique properties due to its structure, and now researchers have used one featuring a small sawtooth pattern on its surface to move and position ...
