Acoustic streaming generated by airborne ultrasonic phased arrays plays a critical role in the performance of advanced ultrasonic technologies, including midair haptic feedback, odor delivery, and ...

Physicists in Australia have become the first researchers to levitate a macroscopic object using lasers. The physicists used three lasers to form a levitational "tripod" that could hold a small mirror ...

NASA are to thank for the discovery of high-voltage electrostatic levitation - but is this a step toward something greater, like... humans levitating? This is just proof that physics is basically a ...
