Measuring conditions in volatile clouds of superheated gases known as plasmas is central to pursuing greater scientific ...

Engineers working with the Pentagon’s advanced research arm and a Seattle startup say they are closing in on “infinite flight” for drones by zapping them with high powered lasers from the ground.

researchers at Colorado University Boulder have used doughnut-shaped beams of light to take detailed images of objects too tiny to view with traditional microscopes. The researchers say that the new ...

Some days really are longer than others. And now scientists know by precisely how much. Using a laser gyroscope, scientists have measured variations in Earth’s rotation rate smaller than a millionth ...

Gisela Eckhardt was one of the early pioneers in laser physics, discovering the principle behind the Raman laser in 1962. Valdas Pasiskevicius, Richard Mildren and David Burman tell the largely ...
