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.

Researchers in Switzerland have found a way of using sound waves to manipulate objects in disordered environments such as liquids. Instead of trapping the objects as conventional optical and acoustic ...

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 ...

Using ultra-fast laser pulses and special cameras, scientists have simulated an optical illusion that appears to defy Einstein's theory of special relativity. One consequence of special relativity is ...

In 2018, Arthur Ashkin won the Nobel Prize in Physics for inventing optical tweezers: laser beams that can be used to manipulate microscopic particles. While useful for many biological applications, ...

Researchers have detailed the physics behind a phenomenon that allows them to create spin in liquid droplets using ultrasound waves, which concentrates solid particles suspended in the liquid. The ...

Many of the nation’s fire departments and rescue squads provide technical rescue services to their respective communities. Working in the world of rescue, a member understands that rescue is the ...

A team of material engineering research from Rutgers University-New Brunswick have 3D-printed soft gel-based mini-robots that not only walk and change shape when activated by electricity but also ...
