What if particles don't slow down in a crowd, but move faster? Physicists from Leiden worked together and discovered a new state of matter, where particles pass on energy through collisions and create ...

WASHINGTON — One of the enduring sci-fi moments of the big screen — R2-D2 beaming a 3-D image of Princess Leia into thin air in “Star Wars” — is closer to reality, thanks to the smallest of screens: ...

A new study published in Physical Review A suggests that, somewhat counterintuitively, quantum particles have a chance of moving backwards, even when pushed forwards. The rest of this article is ...

There's an ultimate speed limit in the Universe: the speed of light in a vacuum, c. If you don't have any mass — whether you're a light wave (a photon), a gluon, or even a gravitational wave — that's ...

In the new device, an array of 256 speakers, each about 1 centimeter wide, faces another, identical speaker array across a distance of 23 centimeters. The speakers emit sound waves at frequencies too ...

A new imaging system that captures visual data at a rate of one-trillion-frames per second is fast enough to create virtual super-slow-motion videos of light particles traveling and scattering through ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. Deep underground in Europe, the world's most powerful particle ...

Are quantum particles polygamous? New experiments suggest some of them abandon long-standing partnerships when ...

Researchers at the Centre for Nano Science and Engineering (CeNSE), IISc, have developed a technique to trap and move nano-sized particles in a fluidic medium using only light. The nanotweezer ...

In the home, the lab and the factory, electric fields control technologies such as Kindle displays, medical diagnostic tests and devices that purify cancer drugs. In an electric field, anything with ...
