Scientists have developed a powerful new technique that acts like a “light switch” for oxytocin, often called the brain’s love hormone, allowing it to be activated with extraordinary precision. The ...

Physicists have taken a step that sounds like science fiction: they have coaxed light into behaving as a “supersolid,” a phase of matter that is at once rigid and frictionless. Instead of treating ...

Getting light deep inside the body has always come with a catch. Tissue scatters and absorbs it, which means doctors and researchers often have to cut into the body or thread in optical fibers to ...

San Francisco-based entrepreneur Antony Evans plans to insert genes from bioluminescent bacteria into a species of flora as a first step to creating glowing trees. Antony Evans San Francisco-based ...

A light-sensitive crystal is opening the door to a new era of “light-written” technology. Arsenic trisulfide can be reshaped ...
