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 ...

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 ...

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 ...

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 ...

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: ...

Landslides are one striking example of erosion. When the bonds that hold particles of dirt and rock together are overwhelmed by a force — often in the form of water — sufficient to pull the rock and ...
