Wellness influencers tout the therapy's power for everything from rejuvenating skin and hair to boosting longevity. Devices sold for at-home use abound. We look at the evidence behind the hype.

Researchers have developed a light-driven method for creating tiny, high-energy “housane” molecules that are valuable for ...

Red light therapy has gone from dermatology clinics to the wellness world, promising everything from younger-looking skin and thicker hair to weight loss, pain relief, better sleep, and even improved ...

Researchers in China published a paper describing a theoretical model for photonic computing that used light particles instead of electrons for faster processing. The team developed “parallel optical ...

Imagine a sea of glowing blue lights pulsing to the beat of the music. But instead of glow sticks filled with toxic chemicals, the luminescence comes from living algae, shimmering on demand. In a new ...

Researchers at Stanford have developed a compact optical amplifier that dramatically boosts light signals using very little power. By recycling energy inside a looping resonator, the device achieves ...

In 1845, Michael Faraday discovered what’s known today as the Faraday Effect—which describes how light and electromagnetism are related. A new study revealed that the magnetic component of light ...
