Gravitational waves are mysterious ripples in the fabric of space and time that travel across our universe at the speed of light. Predicted by Einstein exactly 100 years ago, a number of experiments have been searching for ...

(Phys.org)—Over the past few years, scientists have demonstrated the phenomenon of "one-way light," in which a light beam propagates in one direction only. The materials used to achieve this effect can be thought of as ...
Researchers working at the National Institute of Standards and Technology (NIST) have developed a novel way to noninvasively measure and map how and where trapped light vibrates within microscale optical resonators.

The story of the drawn-out development of Albert Einstein's revolutionary rewrite of the laws of gravity has been told many times, but over the past 100 years it has given us extreme stars and black holes, expanding universes ...

The most widely used technology for producing X-rays – used in everything from medical and dental imaging, to testing for cracks in industrial materials – has remained essentially the same for more than a century. But ...

It might be easier to track tiny particles in the future – even when they hurtle along with the speed of a rifle bullet. This is thanks to researchers working with Christoph Marquardt and Gerd Leuchs at the Max Planck Institute ...

Photonic circuits, which use light to transmit signals, are markedly faster than electronic circuits. Unfortunately, they're also bigger. It's difficult to localize visible light below its diffraction limit, about 200-300 ...

The performance of solar cells, flat panel displays, and other electronics are limited by today's materials. A new material, created by modifying a transparent insulating oxide, replacing up to 25 percent of the lanthanum ...

Before beaming 300 miles to Earth's surface, bouncing off the ground and travelling another 300 miles back into space, the laser photons on NASA's Ice, Cloud and Land Elevation Satellite-2 first have to complete a 7½-foot ...
