Dive deep, and meet the flashlight squid — with a billion-bacteria light bulb. Meet bacteria that live in boiling water, and the immense variety of weirder-than-weird critters that live between grains of sand. Plus a highly selected bio-freak show…

Bacteria can help or harm their hosts. Now we hear how one genus of bacteria can multiply fly reproduction. In this symbiosis, both parties benefit. This bacterium also alters insect immunity, and could lead to new tactics for killing horrific parasites.

To hide from hungry fish, this animal houses luminous bacteria. But what prevents the bacteria from reproducing and killing the squid? At last, a genetic a balancing mechanism is revealed.
