The numbers you see on the box don't always work out in real life. LED bulbs do last longer, but those claims about five to 10 years are estimates based on internal testing -- and companies are always ...

Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

A new mechanism steers diodes made of a single enantiomer to emit light of right- and left-handed polarizations ...

African forests are now emitting more carbon dioxide than they absorb, a fundamental shift that will make it more difficult for the world to cut its net emissions to zero. Forests and shrubby ...

Miniaturization ranks as the driving force behind the semiconductor industry. The tremendous gains in computer performance since the 1950s are largely due to the fact that ever smaller structures can ...

This illustration depicts the QAO family dopant integrated into the organic light-emitting diode structure. By designing a molecule with a lower HOMO level than that of the host material, the ...

Interstellar object 3I/ATLAS — which is zooming through our inner solar system — appears to be emitting its own light, according to Harvard astrophysicist Avi Loeb. The observation by Loeb, if ...

Last month, astronomers made an exciting discovery, observing an interstellar object — only the third ever observed — hurtling toward the center of the solar system. The object, dubbed 3I/ATLAS, has ...

Wearable electronics have evolved from basic fitness trackers to sophisticated health-monitoring systems, demanding light-emitting devices that balance visual quality, power efficiency, and mechanical ...

In a first for the field, researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have reported a photopumped lasing from a buried dielectric ...
