Physicists have recreated the Nobel Prize–winning quantum Hall effect using light, revealing that photons can follow the same ...

For more than 40 years, scientists have known that the quantum Hall effect impacts electrons in strong magnetic fields, but it turns out light also follows the fundamental phenomenon.

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 ...

We live in a world where smartphones last for about 2.5 years, and even the best light bulbs fizzle out unexpectedly when you need them the most. That said, here is one bulb defying the odds, a ...

Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus ...

NYU researchers have found a way to use light to control how microscopic particles assemble into crystals, effectively turning illumination into a tool for shaping matter. By adding light-sensitive ...
