The Guardian reports that scientists in Chicago have created a cyborg:

Researchers in Chicago have built a cyborg, a half-living, half-robot creature which connects the brain of an eel-like fish to a computer and is capable of moving towards lights.

The device, developed at a research centre owned by Evanston’s Northwestern University, consists of the brain stem from the larva of a lamprey, a bloodsucking fish, attached by electrodes to an off-the-shelf Swiss robot.

In an arrangement reminiscent of the genesis of the Daleks, the living brain floats in a container of cool, oxygenated salt fluid.
