March of the Spermbots

Spunk-seeking nanotechnology experts at Cornell say that sperm would make the perfect nanobots of the future. Robot sperm (pictured here in an artist's rendering) would deliver new DNA or other molecules to your body by scooting through your bloodstream using a tail powered by its own energy source. Find out why sperm are self-contained power-houses after the jump.

Apparently, sperm tails contain their own energy-producing system that grabs glucose out of your blood and coverts it instantly to fuel. That special engine is why Cornell scientists are saying they want to model nanobots on sperm: spermbots will manufacture energy from their host bodies. Image courtesy of
