For example, light can only manipulate matter that’s very tiny (up to about 50 microns, the size of a human liver cell), whereas magnetic levitation requires the material to have special properties.

For those that haven’t heard, ultrasonic levitation is a process by which two or more ultrasonic transducers are set opposite to each other and excited in such a way as to create a standing w… ...

In previous work on levitation systems, researchers had used transducers to produce sound waves, and reflectors to reflect the waves back, thus creating standing waves. "A standing wave is like ...

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 ...
