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 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 ...

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 ...

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 ...
