Physics is supposed to be predictable. Drop a ball, and gravity pulls it down. Heat water, and it boils. Light travels in straight lines. Yet throughout history, scientists have encountered ...

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 ...

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 ...

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

Perovskite crystals can dramatically and reversibly change shape when hit with light, a behavior not seen in conventional semiconductors. This effect, called photostriction, can be finely tuned ...

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 ...

It has been known since the 1960s that the quantum statistical properties of light have a role in optical processes 3. For example, when more than one photon is required to ionize an atom, random ...

On a cold November day, Kiana Aran awoke to a surreal vision: Beyond a glass partition, she saw her mother, her cousin, and her grandmother—who had passed away years earlier—watching something on an ...

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