When the photon strikes one of the light-sensitive cells in the retina, it is absorbed by an opsin molecule. The colour-sensing cone cells use three different photopsins, one for each primary colour.

Researchers at the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, Germany, together with international ...

The first direct visualization of the shape of a photon has been created. These particles of light are impossible to photograph, but UK physicists have now calculated their wave function to ...

Enter a technology called the photon sieve: a sort of lens that helps subtly bend ultraviolet light toward a camera. To be clear, a photon sieve is no ordinary lens; it is a cutting-edge work of ...

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.

While auras may come from the realm of pseudoscience, all living beings do emit a faint light, invisible to the human eye—one that is extinguished upon death.. This is the conclusion of a team ...
