Dragonflies and humans can see colors similarly, thanks to a common protein in the eye that resulted from parallel evolution.

Researchers from Japan showed that a single organic crystal converts invisible light into visible colors, emitting red light under ultraviolet irradiation and green light under near-infrared ...

In a lab in Zurich, scientists have built something that, at first glance, shouldn’t be possible. When a beam of infrared light strikes their ultra-thin lens—barely thicker than a red blood cell—it ...

It’s a breakthrough straight out of science fiction: scientists have created the world’s first contact lenses that let humans see infrared light — even with their eyes shut. Developed by researchers ...

Researchers have developed a novel experimental platform to measure the electric fields of light trapped between two mirrors with a sub-cycle precision. These electro-optic Fabry-Perot resonators will ...

Electromagnetic radiation—light—is everywhere, but it’s not all visible to the naked eye. Astronomy writer Berman (Zoom) runs through a fascinating history of the rainbow’s invisible bands in this ...
