There’s a new kind of twisted light. A rotating “vortex beam” whose twist changes across the length of the beam has been created in the lab for the first time. Researchers discovered in 1992 that a ...

The entirely new structure of light could help drug developers see their work more clearly than before. An entirely new structure of light is helping to measure chirality in molecules more accurately ...

Recently, the Laboratory of Micro and Nano Engineering, School of Engineering Science, University of Science and Technology of China (USTC) has made important progress in the field of structural ...

Smoke rings are being seen in a new light. Doughnut-shaped structures called vortex rings are sometimes seen swirling through fluids. Smokers can form them with their mouths, volcanoes can spit them ...

Short pulses from a laser can be twisted into a series of doughnut-like vortices, offering a way to transmit more information using light. We usually encounter vortices in water and air, but similar ...
