Scientists at Oregon State University have engineered a powerful new nanomaterial that zeroes in on cancer cells and destroys them from the inside out. Designed to exploit cancer’s unique ...

The application of modulated UV-C light to guavas—emitted in pulses or cycles rather than continuously—combated anthracnose. This fungal disease is caused by microorganisms belonging to the ...

Discover how to build a magnetic repulsion motor capable of lighting LED bulbs using only magnets and basic components. This step-by-step tutorial covers the construction of the magnetic base, the ...

An international research team has achieved record perovskite solar module stability under light, heat, and UV stress with a chemistry-driven passivation technology that is industry-compatible.

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.

... this only occurs in specific, somewhat rare conditions. Otherwise, clouds generally tend to dampen UV rays. In short, while studies have found that clouds can ...

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 ...

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 ...

Scientists have developed a fully transparent skin sensor that accurately measures UV radiation, detecting light and converting it to electrical signals. So when the Sun's rays reach damaging levels, ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. While ultraviolet (UV) light is harmful for human skin, it could ...

Cats. Dust mites. Mold. Trees. For people with allergies, even a brief whiff of the airborne allergens these organisms produce can lead to swollen eyes, itchy skin and impaired breathing. Such ...
