A new method could pave the way for shrinking particle accelerators from the length of Rhode Island to the length of a dining room table.

A new method can turn any metal surface into an antimicrobial material by changing its texture with lasers, researchers report.

"Our optical tweezer method lets us take the little machines out of the cell, gently hold onto them, and watch them go."

A new approach (and a smaller laser) lets scientists shrink laser-induced graphene for flexible electronics.

Currently, no one test can diagnose concussion. Researchers say a new device that uses infrared lasers could offer the first step in changing that.

Researchers have used femto-second laser pulses to etch nano-sized designs onto black metal, turning it into a solar energy absorber.

Knowing how laser beams interact in a plasma—a hot soup of free moving electrons and ions—will boost the accuracy of computer models used in simulations of laser-driven implosions.

Zooplankton migration is "the greatest migration on Earth. It happens every day and it's amazing." A satellite view reveals the hordes of tiny creatures.

Artificial intelligence could clear up pictures taken with a relatively new technology, optoacoustic imaging, that uses lasers to peek under the skin.

Researchers have plans for a microscopic crystal that can trap to wavelengths of light, which could lead to quantum computers and faster telecommunications.
