We are faced with a global epidemic of myopia (short-sightedness) because we are deprived of deep violet light (360-400 nm).

A Korean research term has fabricated a perovskite-organic solar cell with a uniform sub-nanometer dipole layer. The device ...

S ome animals have a curious way of emitting light that we humans can see when we shine a blacklight on them, a pastime that ...

Researchers have developed a high-efficiency and high-stability organic-inorganic hybrid solar cell production technology that maximizes near-infrared light capture beyond the existing visible light ...

Cycling is so #!@% gear-oriented. But don't worry — we've curated the best gifts for cyclists from 4 decades of experience.

Lawmakers were told light pollution is increasing in New Mexico and the Night Sky Protection Act needs to be updated.

Researchers created a metalens focusing all visible light equally across 400–700 nm by engineering meta-atoms with dispersion-matched layers. This improves group delay control, enabling ...

Chrissy: The light from the rising Sun signals our body to reduce melatonin, helping us wake up. This visible light has ...

Many people think of the James Webb Space Telescope as a sort of Hubble 2. They understand that the Hubble Space Telescope (HST) has served us well but is now old and overdue for replacement. NASA ...

The better approach? Give yourself a full spectrum of lighting possibilities by making sure all of those lights are dimmable. Upgrading your light switches to dimmer switches is one way to do it ...
