The Human Meat Mole

webword writes "SciTech Daily is reporting on a 'mole' that Japanese scientists have developed that can cut through a 2cm thick chunk of beef steak in 20 seconds. The tiny machines could be injected into a vein, and could be steered around the body using an external magnetic field. The idea is to use them to remove cancerous tissue and move drugs around the body. Not that anyone cares, but they remind me of the bore worms from Flash Gordon."
