In a new preprint study, researchers at Carnegie Mellon University claim sound can be used to predict an object's appearance -- and its motion. The coauthors created a "sound-action-vision" data set ...

Researchers in the US have made a “carpet cloak” that makes objects invisible to sound waves. The device is the first such cloak to work in air and could be used to improve the acoustics in concert ...

Amanda D. Hanford, at Pennsylvania State University, is taking the introductory steps to make acoustic ground cloaks. These materials redirect approaching waves around an object without scattering the ...

Researchers at the University of Bristol have been able to levitate objects using ultrasonic waves larger than the wavelengths of sound used by the device. This could enable touchless control of drug ...

A new "tractor beam" can levitate large objects in midair, using only sound. So far, researchers have floated spheres as large as 0.6 inches (16 millimeters) in diameter and moved orbs as large as 0.8 ...

Although their technique employs a method similar to laser trapping in biology, adaptable to a wider range of particle sizes and materials. The ability to move objects without touching them might ...

When an object in space appears to be racing at nineteen times the speed of sound, it instantly jumps from routine data point to global headline. The claim that NASA tracked such a hyperfast visitor ...
