Getting light deep inside the body has always come with a catch. Tissue scatters and absorbs it, which means doctors and ...

Researchers generated stable vortex light in its lowest-energy state using liquid crystal traps and optical confinement.

Researchers at Stanford have developed a noninvasive method to create light anywhere in the body. Their technique, which uses ultrasound waves to activate light-emitting nanoparticles, could be used ...

Owing to the wave nature of light there are many ways that such different waves can interact with each other, but also with materials. Everyone knows about reflecting light with a mirror, which is a ...
