US-Italy researchers have used quantum-mechanical simulations to resolve a decades-old puzzle about how ultraviolet (UV) light interacts with ice. This question’s influence is huge, shaping both our ...

Scientists at the University of East Anglia have uncovered a hidden property of light that allows it to twist, spin and behave differently—without mirrors, materials or special lenses. In a ...

It may not be great on the eyes, but it could be a new way to take care of those pit stains. By Andrew Paul Published Sep 3, 2025 10:00 AM EDT Add Popular Science (opens in a new tab) More information ...

Researchers from Skoltech and the Shanghai Institute of Optics and Fine Mechanics have developed an approach that helps optimize the parameters of a laser-plasma source of attosecond pulses—ultrashort ...

Red light therapy devices are everywhere—from lamps, to full-body mats, to those glowing face masks flooding my social media feed. I usually see red light therapy advertised for "younger-looking skin, ...

Put on your lab coat! It's time for another series of Play School's Science Time! With help from some very clever friends, ...

On TikTok, you'll find content creators touting red light therapy's benefits for skin care, hair growth, joint pain, sleep, longevity, inflammation — even period cramps. As one TikTok creator who goes ...

Researchers have developed a technology to invisibly transmit information disguised as background thermal radiation. Using a phenomenon called "negative light," they transferred 100 kilobits of data ...

A new brain-machine interface (BMI) uses light to "speak" to the brain, mouse experiments show. The minimally invasive wireless device, which is placed under the scalp, receives inputs in the form of ...

Attosecond pulses capture ultrafast electron and light–matter dynamics on the shortest timescales accessible to controlled experiments, making them indispensable tools for ultrafast spectroscopy, ...
