An extraordinary experiment on mice and leaves from two different plant species has uncovered direct physical evidence of an ...

How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

A new type of polymer material that can be patterned using gentle visible light, creating stable hidden images visible only ...

Life, in its quietest moments, glows gently—so subtly that it’s invisible to your eyes but bright enough for science to detect. Recently, researchers from the University of Calgary and the National ...

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 ...

Researchers have developed a low-cost visible light communication (VLC) system using commercially available hardware that ...

Human bodies are not quite as dark as they look. A growing body of research suggests that living tissue constantly releases ...
