Researchers from Swedish and American universities say that they have solved the mystery as to why giant and colossal squid have such enormous eyes, and perhaps unsurprisingly, the oversized ocular orbits are essentially a defense mechanism.

Tumor-targeted bioluminescent bacteria have been shown for the first time to provide accurate 3D images of tumors in mice, further advancing the potential for targeted cancer drug delivery.

It has long been known that distinctive blue flashes--a type of bioluminescence--that are visible at night in some marine environments are caused by tiny, unicellular plankton known as dinoflagellates..

The world's only bioluminescent millipedes use their glow as a warning signal to nocturnal predators, a University of Arizona-led research team has discovered.
