New Scientist - Powered by acid and capable of moving at blistering speeds in excess of 640 kilometres per hour, scientists in California have created a novel and quite lethal-sounding torpedo. But this one has rather more of a humanitarian agenda.
Like something out of the Fantastic Voyage, the torpedo is just 10 microns in length and designed to travel within the human body with the aim of delivering drugs, says Joseph Wang at the University of California, San Diego.
