A new metasurface lets scientists flip between ultra-stable light vortices, paving the way for tougher, smarter wireless communication.

A research team from Munich has identified a previously unknown communication mechanism in harvestmen. Five closely related ...

In a new leap for neurobiology and bioelectronics, Northwestern University scientists have developed a wireless device that uses light to send information directly to the brain—bypassing the body's ...

Spatial variation in lighting environments frequently leads to population variation in colour patterns, colour preferences and visual systems. Yet lighting conditions also vary diurnally, and many ...
