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 ...

It's not nearly powerful enough to pull in the Millennium Falcon, but four groups of physicists have independently come up with the same basic idea for a real-life tractor beam. The laser beam the ...

Using light to attract objects is a much explored topic for almost a century. Perhaps you’ve tuned in to an episode of Star Trek in which characters use a “tractor beam” that could pull space ships ...

Researchers at the Universities of Sussex and Bristol, in collaboration with Ultrahaptics, have now built a working tractor beam that uses high-amplitude soundwaves to generate an acoustic hologram ...

This video shows a real live tractor beam in action. It uses an array of small speakers to levitate objects and to move them precisely through the air. The beam can even pull objects from above, just ...

Levitation is no longer just the realm of magicians, with engineers dabbling in ways to suspend objects in midair using magnets, heat flow or sound waves. Unfortunately, it usually only works with ...
