Physicists have recreated the Nobel Prize–winning quantum Hall effect using light, revealing that photons can follow the same strange quantum rules once thought exclusive to electrons.

Scientists at Harvard have built a miniature device that can twist and tune light in real time. By rotating two stacked photonic crystals and adjusting their spacing with a tiny mechanical system, they can control how light’s “handedness” behaves.

There are worlds like hot Jupiters, gigantic and very hot, as well as ocean worlds and super-Earths with a rocky structure but a much thicker atmosphere than our own planet. Now, a new study suggests the existence of a new type of planet,

The human body has long been studied through the lens of chemistry and electrical signaling, but an emerging field of research is adding a fascinating new dimension: light. Scientists have discovered that our cells emit tiny flashes of light called ...
