A programmable semiconductor changes its electronic properties under UV light and reverts under a different wavelength, enabling optical writing and reading for potential computing applications.

UV-C light is a type of ultraviolet light with shorter wavelength and more energy than UV light of type A and B. Photonic components operating in the UV-C range can unlock new opportunities across ...

In 1845, physicist Michael Faraday provided the first direct evidence that electromagnetism and light are related. Now, it turns out that this connection is even stronger than Faraday imagined. In his ...

Imagine switching on a light at home that can disable airborne allergens within minutes. The unstoppable sneezing, itchy skin and swollen eyes finally ease up. Well, a team at the University of ...

Six species of North American bats—big brown bats (pictured), eastern red bats, Seminole bats, southeastern myotis, gray bats and Brazilian free-tailed bats—glow green under ultraviolet light, new ...

Glowing bats may sound like Halloween decor, but researchers in Georgia have discovered certain species of North American bats that are capable of the unusual trick. When placed under ultraviolet ...

The ability to spot rubs and scrapes is an acquired skill. They may be invisible to rookie hunters, but with a little bit of practice, spotting them becomes routine. Whitetails don’t have to work ...

Scientists have shown that far-UVC lights, which are already commercially available, can rapidly break down common airborne allergens, offering a safe and fast new way to ease asthma and allergy ...
