Glowing millipede genitalia help scientists tell species apart

Sometimes, it's really easy for scientists to tell species of animals apart—they'll be obviously different shapes or colors. Other times, different species will look nearly identical to the naked eye. In those cases, scientists ...

Novel approach promises ready access to hard-to-study proteins

DNA and the genome, we know, provide the blueprint for life. But it is the proteins made according to the genome's instructions that are the nuts and bolts of living organisms, providing the molecular building blocks for ...

Lab develops quantum dot polymer for next-gen screens

U.S. Naval Research Laboratory scientists have developed and patented the fabrication of transparent, luminescent material they say could give smartphone and television screens flexible, stretchable, and shatterproof properties.

Fluorescence discovered in tiny Brazilian frogs

An international team of researchers led by NYU Abu Dhabi Postdoctoral Associate Sandra Goutte was studying the acoustic communications of these miniature frogs. When they discovered that Brachycephalus ephippium could not ...

NIST researchers boost intensity of nanowire LEDs

Nanowire gurus at the National Institute of Standards and Technology (NIST) have made ultraviolet light-emitting diodes (LEDs) that, thanks to a special type of shell, produce five times higher light intensity than do comparable ...

Ultraviolet

Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than x-rays, in the range 10 nm to 400 nm, and energies from 3 eV to 124 eV. It is so named because the spectrum consists of electromagnetic waves with frequencies higher than those that humans identify as the color violet.

UV light is found in sunlight and is emitted by electric arcs and specialized lights such as black lights. As an ionizing radiation it can cause chemical reactions, and causes many substances to glow or fluoresce. Most people are aware of the effects of UV through the painful condition of sunburn, but the UV spectrum has many other effects, both beneficial and damaging, on human health.
