One-fifth of global electricity consumption is based on lighting; efficient and stable white-light emission with single materials is ideal for applications. Photon emission that covers the entire visible spectrum is, however, ...
(Phys.org)—Cell phones and Wi-Fi devices typically transmit data using radio waves, but as the demand for wireless data transfer increases, congestion in the radio spectrum is expected to become more of a problem. One way ...
An invention that promises to revolutionize the way the world lights its homes and offices—and already helps create the glowing screens of mobile phones, computers and TVs— earned a Nobel Prize on Tuesday for two Japanese ...

(PhysOrg.com) -- Researchers from the Nichia Corporation in Tokushima, Japan, have set an ambitious goal: to develop a white LED that can replace every interior and exterior light bulb currently used in homes and offices. ...
(PhysOrg.com) -- Scientists have developed a lighting device that can change its color temperature throughout the day, matching the natural daylight chromaticities produced by the sun. Currently, no other type of lighting ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a peculiar cataclysmic variable star. The newly found system, designated SDSS J134441.83+204408.3 (or J1344 for short) is a highly asynchronous, ...
Using data from various space telescopes, astronomers have investigated a variable X-ray source known as SWIFT J0503.7-2819. Results of the study suggest that this source is an intermediate polar. The finding was detailed ...
Using the AstroSat spacecraft, Indian astronomers have investigated an open cluster known as NGC 2506. The study identified more than 2,000 member stars of this cluster and provided more insights into its properties. The ...
Using ESA's XMM-Newton satellite and NASA's Chandra spacecraft, an international team of astronomers has investigated a peculiar behavior of quasi-periodic eruptions (QPEs) in an active galaxy known as GSN 069. Results of ...
Using ESA's XMM-Newton satellite, astronomers from the Columbia University in New York have inspected a peculiar cataclysmic variable system known as Swift J0503.7−2819. Results of the study, presented June 29 on arXiv.org, ...
