Tiny lamprey-inspired robot could locate diseases inside the human body

Could tiny robots one day swim through our bodies to detect disease? That's the vision of scientists in the U.K. and U.S. who have turned to the sea lamprey for inspiration in an effort to design a micro-robot capable of doing just that. While not the prettiest of sea creatures, the jawless, blood-sucking lamprey finds itself the subject of this biomimicry project not only because of its ability to swim, but because of its primitive nervous system, which researchers believe can be reproduced as part of a micro, or even nano-scale robot.
