Light therapy can boost your mood, but you need the right model. Here's what experts say about picking an effective model.

Carbon nanotubes are moving from lab curiosities to workhorse components in quantum hardware, and one of the most striking examples is their use as single-photon light sources. By exploiting their ...

Winter means less time in the sun, but there are foods that can help you get the vitamin D your body needs to function.

Tiny tubes of carbon that emit single photons from just one point along their length have been made in a deterministic manner by RIKEN researchers. Such carbon nanotubes could form the basis of future ...

If Santa and his sleigh traveled at 10% the speed of light, Rudolph’s nose would be blueshifted to look orange as he ...

New research shows that light’s magnetic field is far more influential than scientists once believed. The team found that this magnetic component significantly affects how light rotates as it passes ...

In 1845, physicist Michael Faraday provided the first direct evidence that electromagnetism and light are related. Now, it turns out that this connection is even stronger than Faraday imagined. In his ...

University of Tennessee provides funding as a member of The Conversation US. When people name the most important inventions in history, light bulbs are usually on the list. They were much safer than ...

In nature, many organisms glow in the dark, including lightning bugs, some squid and jellyfish, using light to attract a mate or lure prey. Now, researchers have engineered glowing succulents, plants ...

An AI image generator that uses light to produce images, rather than conventional computing hardware, could consume hundreds of times less energy. When an artificial intelligence model produces an ...
