Stellar waltz with dramatic ending

Astronomers at the University of Bonn and their colleagues from Moscow have identified an unusual celestial object. It is most likely the product of the fusion of two stars that died a long time ago. After billions of years ...

Squid skin inspires creation of next-generation space blanket

Drawing design inspiration from the skin of stealthy sea creatures, engineers at the University of California, Irvine have developed a next-generation, adaptive space blanket that gives users the ability to control their ...

A light-based carrier system for CRISPR-Cas9 gene editing

A team of researchers from Nanjing and Xiamen Universities in China has developed an alternative to using viruses to transport CRISPR-Cas9 gene editing tools into a desired cell—and it involves two types of light. In their ...

Nanotechnology makes it possible for mice to see in infrared

Mice with vision enhanced by nanotechnology were able to see infrared light as well as visible light, reports a study published February 28 in the journal Cell. A single injection of nanoparticles in the mice's eyes bestowed ...

Invisible tags: Physicists write, read and erase using light

A team of physicists headed by Professor Sebastian Reineke of TU Dresden has developed a new method of storing information in fully transparent plastic foils. Their innovative idea has been published in Science Advances.

New infrared telescope first to monitor entire northern sky

Infrared (IR) radiation is electromagnetic radiation whose wavelength is longer than that of visible light (400-700 nm), but shorter than that of terahertz radiation (100 µm - 1 mm) and microwaves (~30,000 µm). Infrared radiation spans roughly three orders of magnitude (750 nm and 100 µm).

Direct sunlight has a luminous efficacy of about 93 lumens per watt of radiant flux, which includes infrared (47% share of the spectrum), visible (46%), and ultra-violet (only 6%) light. Bright sunlight provides luminance of approximately 100,000 candela per square meter at the Earth's surface.
