Cornell researchers have built a programmable optical chip that can change the color of light by merging photons, without ...

Could black holes help explain the origins of high-energy cosmic radiation? The universe is filled with many forms of ...

Scientists may have finally uncovered the mystery behind ultra-high-energy cosmic rays — the most powerful particles known in ...

Lighten up, people: a fascinating new paper has dropped that describes the shape of a single photon, the smallest possible form of energy in an electromagnetic field that we commonly know as light.

Ultraviolet (UV) light has higher energy photons than visible light and, thus, has more applications. Researchers have now developed a brilliant innovation -- a solid-state material that can stably ...

A new paper suggests that we could search for photons created by gravitational waves. A specific physical response turns gravitons from these waves into photons of electromagnetism. Scientists believe ...

How does sunscreen work on the atomic level? Summer 2023 in the Northern Hemisphere is on track to be the hottest on record, and the sun is blazing in the sky. One way to deal with it is to slap on ...

I don’t know, ask Erwin Schrödinger. He was a relative of mine on my mother’s side. He told her mum, but she couldn’t understand it either. We’ve been in the dark ever since. The laws of the universe ...
