Thunderstorms can generate weak electrical discharges on the plants underneath, but until now, they had never been observed in nature ...

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 ...

When a predator like a lion walks through the grasslands, it makes its presence known by roaring, which can be heard miles away. Since the lion is at the top of the food chain, it doesn’t particularly ...

Adjusting the size and chemistry of nanocrystals within an ultrathin surface can speed up light-driven chemical reactions, ...

Ultraviolet or infrared light beyond the range of human vision plays a vital role in communication technologies, medical diagnostics, and optical sensing. UV (100–400 nm) and NIR (0.75–1.4 μm) ...

Researchers have theoretically presented terahertz (THz) modulation of UV light by a graphene nano-ribbon from computational simulation and proposed the application to a terahertz radiation device.

Blue light is a high-energy part of visible light from the sun, screens, and light-emitting diode (LED) bulbs. Your cornea and lens don’t block blue light the way they block ultraviolet (UV) rays.

A storm system descending out of the Pacific Northwest will generate rain — and light snowfall at higher elevations — across the Inland Empire beginning Tuesday evening, with another system ...

Here at Hackaday, we love a good art piece, whether that involves light or sound. Combining both is a sure-fire way to get our attention, and [Eirik Brandal] did just that with his Void Extrusion ...
