Dark structures inside light waves can briefly move faster than light without breaking relativity or transmitting energy or information.

Physicists have accomplished a quantum leap in light research. They have managed to capture the behavior of extremely short laser pulses during focusing by means of very high spatial and temporal ...

The late 20th and early 21st century have seen a revolution in the study of light. Far from the old days of seeing things dimly through microscopes, we are now in the position to freeze light, use it ...

A polymer that incorporates liquid-crystal components generates continuous mechanical waves when lit by ultraviolet light, with potential applications for energy harvesting and self-cleaning surfaces.

Cosmic claims: researchers have used radio telescopes around the world to hunt for gravitational waves using the subtle variations in the timing of pulsars. (Courtesy: Aurore Simonnet for the NANOGrav ...
