In laboratories from Brazil to Munich, researchers are learning to grab matter with sound alone, sculpting ultrasonic waves into invisible “hands” that can lift, push, and rotate objects without a ...

Imagine trying to catch a fragment of a rocket nozzle in orbit above Earth’s atmosphere. The fragment is travelling faster than a bullet, and tumbling rapidly end over end. Around 27,000 orbiting ...

Engineers have come up with a scaling law to describe how objects move through sand. The scaling law can be used to predict how large trucks and cars drive through this material, based on how toy ...

Researchers have developed a technique to move objects around with a jet of wind. The new approach makes it possible to manipulate objects at a distance and could be integrated into robots to give ...

A team of researchers at the University of Minnesota Twin Cities have been working on a way to move objects without any contact! They developed a way to manipulate objects using ultrasound waves.

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 ...
