A closed door feels absolute. Light stays in one room, darkness settles in the next, and the boundary seems obvious enough to ...

An international team of physicists has achieved a significant advance in laser science, demonstrating for the first time a ...

(Aitor Diago/Moment/Getty Images) For the first time, physicists have observed that 'holes' in light can move faster than the light itself. They're known as phase singularities or optical vortices, ...

Reaching the nearest star system, Alpha Centauri, would take hundreds of thousands of years using current rocket propulsion ...

A rare close approach of Venus and Uranus is treating observers to a shared view in the evening sky. Separately, researchers have uncovered new insights into light's helicity, produced record-intense ...

In a mind-warping milestone experiment, scientists have been able to manipulate small numbers of individual photons of light, opening doors for the development of quantum technologies. This research, ...

Australian physicist has developed a device that can bend light using gravity and has applications in areas of defense, ...

Scientists experimentally confirmed what we’ve known to be true for half a century—darkness can “travel” faster than light.

In materials science, if you can understand the "texture" of a material—how its internal patterns form and shift—you can ...

By harnessing the unique properties of tantala (tantalum pentoxide), a team of US-based researchers has created a photonic integrated circuit that can be tuned to deliver laser light across a broad ...
