Quantum tunnelling — when a particle skips through a barrier that classical physics would forbid — happens faster when objects have less energy, find physicists who worked out a way to probe photons ...

Two studies fill in gaps about the cosmos’s ordinary matter. One maps it all, even the “missing matter.” The other details one of its hiding spots.

Entangled photons are at the heart of a variety of different and powerful quantum applications. By exploiting this unique quantum phenomenon, in which information correlates between two or more ...

Today in the history of astronomy, satellites Vela 3 and 4 make the first detection of gamma-ray bursts.

There are lots of situations where getting a look at the human brain can be very helpful. Unfortunately, our heads are ...

Two promising dark matter candidates (i.e., hypothetical particles that dark matter could be made of) are axions and dark photons. The MAgnetized Disk and Mirror Axion eXperiment ...

The Rochester Quantum Network transmits information by sending single photons through two fiber-optic telecommunications ...

It is possible to make a material emit more radiation than it absorbs, violating the laws of physics in a way that could make energy-harvesting devices more efficient ...

To make a truly realistic fake picture of a galaxy, you can model exactly how light particles travel through the atmosphere ...

In its first year alone, it will double the amount of data collected so far by every other instrument in the history of ...

Nick Stone discusses some of the many ways in which light can be used for diagnostic and therapeutic applications ...
