A new kind of laser uses tiny moving particles to produce beams of light. The laser is more programmable than standard lasers and the approach could be used to create visual displays that are sharp ...

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 ...

This insight opens the door for new, efficient strategies to move, sort and separate particles. Discover the latest in science, tech, and space with over 100,000 subscribers who rely on Phys.org for ...

A new dual-light microscope lets researchers observe micro- and nanoscale activity inside living cells without using dyes. The system captures both detailed structures and tiny moving particles at ...

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 ...

Argonne scientists hope that tiny vortices, driven by various magnetic fields, will be able to move microscopic particles. Argonne researchers suspect these magnetic particles can actually talk to ...

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 soil ...

A new method developed at the University of Warwick offers the first simple and predictive way to calculate how irregularly shaped nanoparticles — a dangerous class of airborne pollutant — move ...
