The Cybermen

Cybermen are a race of evil cyborg aliens, nearly as fearsome as the Daleks themselves. Originally an organic species, the Cybermen fused their bodies with computers, inadvertently losing all empathy and emotion. The result: a heartless race of alien robots, bent on conquering worlds and deleting undesirables.While we're nowhere near the promised singularity of fusing our consciousness with machines, mechanical implants in humans are making incredible strides, such as brain-machine interfaces that allow for control of prostheses by thought.And though we (thankfully) don't have Cybermen on planet Earth, scientists might have created the next best thing—cyber-cockroaches. Last year researchers from North Carolina State University demonstrated that an electronic interface could steer a cockroach , turning the tiny insect into a remote-controlled robot. Cockroaches are unlikely to use this technology to take over the world, but regular advances in robotics ensures that the science fiction behind cybernetics is never too far from the truth.
