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 ...

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 ...

A light-sensitive crystal is opening the door to a new era of “light-written” technology. Arsenic trisulfide can be reshaped and permanently altered using simple light, creating ultra-fine optical ...

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 ...

Ionization experiment shows that quantum light can behave like a conventional laser that has a higher intensity. It has been known since the 1960s that the quantum statistical properties of light have ...

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 ...

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 experimentally confirm their 2021 hypothesis that electron-phonon coupling, not electron-electron interactions, explains why some metallic oxides are transparent. (Nanowerk News) ...

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 ...

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