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 ...

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

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 ...

Light usually travels in straight lines, but what if it could twist, spiral, and behave like a miniature tornado? Scientists have now made this possible by creating optical tornadoes (also called ...

Researchers developed a nanoscale quantum resonant tunnelling diode that mimics a sensory neuron, detecting light, processing data, and converting it into electrical signals in one device. (Nanowerk ...
