The new method, which uses quantum dots, performs as well as or better than current infrared light sources while being much ...

Dark matter is one of the biggest mysteries in science. Astronomers believe it makes up most of the matter in the universe, yet no one has ever directly seen it. It does not reflect, emit, or absorb ...

In physics, the classical "Hall effect," discovered in the late 19th century, describes how a transverse voltage is generated ...

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 powers everything from communications to sensing, yet even tiny imperfections can scatter it and weaken signals. To address this, a team led by the University of Bath—working with the University ...

For the first time in history, scientists have succeeded in visually capturing the speed of light. Through an innovative use of high-speed photography and lasers, researchers have managed to ...

Scientists captured the first images of the Terrell-Penrose effect, showing objects near light speed appear rotated rather than compressed in photos.

An international team of physicists has cooked up with a new theory that could allow for objects to travel faster than the speed of light — and while they say it wouldn’t technically violate the laws ...

Superradiance When multiple electrons emit light in a coordinated manner, the resulting emission is much stronger than the sum of individual emissions. (Courtesy ...
