A team of scientists has replicated one of Thomas Edison's early experiments from his quest to make the lightbulb, but with ...

In the strange corner of modern physics where spacetime itself becomes the engine, the old rule that nothing can outrun light ...

A team of engineers and scientists has shown for the first time that a hard-X-ray cavity can provide net X-ray gain, with ...

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, ...

Light can do more than illuminate a material. In some cases, it can temporarily change how electrons move through it.

Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

A cloud of ultracold atoms is like a motel with a neon “no vacancy” sign. If a guest at the motel wants to switch rooms, they’re out of luck. No vacant rooms means there’s no choice but to stay put.

When propagating through a material, a laser beam of significant intensity slightly modifies the density of the physical medium and generates tiny vibrations. These acoustic oscillations distort the ...
