Ultrasonic sound waves have been used to levitate objects in crowded rooms to make hologram-like displays. Such acoustic levitation was previously only practical in empty spaces, but a new algorithm ...

No smoke, no mirrors, just sound was all scientists needed to levitate objects in midair. NPR reports that researchers at the University of Tokyo have discovered a new levitation technique through ...

CHICAGO (Reuters) - U.S. scientists have found a way to levitate the very smallest objects using the strange forces of quantum mechanics, and said on Wednesday they might use it to help make tiny ...

lend itself to producing ultrasensitive detectors and almost friction-free devices by separating their components via Casimir repulsion. "Where you would normally have friction," he says, "you can ...
