When a beam of infrared light strikes their ultra-thin lens—barely thicker than a red blood cell—it emerges on the other side ...

As a result, purple and magenta are known as "nonspectral" colors, because they don't really exist as actual electromagnetic ...

If you live in the southern hemisphere and have been stopped in your tracks by a recent sunset, you may have noticed they ...

Visible' light-emission device technology is reaching its maturity, and many groups have shifted their research focus towards the shorter-wavelength UV devices. This interest is fuelled by the ...

Scientists at the Institute of Quantum Electronics in Zurich, Switzerland, have created a tiny lens that converts infrared ...

A clean, smooth interface between a gallium oxide semiconductor and palladium electrodes enhances the performance of ...

Swiss scientists have developed an ultra-thin lens that turns infrared light into visible light using lithium niobate and ...

or an artificial UV light source. Some animals absorb the UV wavelengths and reflect visible wavelengths, while others seem to display UV coloration—invisible to the human eye without ...

Astronomers have added two more exoplanets to a growing study aimed at finding out whether rocky worlds near small, faint ...

Webb discovered dozens of small, powerful galaxies from 800 million years ago that likely drove cosmic reionization by emitting strong ultraviolet radiation. Astronomers using data from NASA’s James W ...
