Smart dust

A team of researchers at UC-San Diego have created tiny silicon sensors that can orient themselves

"The vision is to build miniature devices that can move with ease through a tiny environment, such as a vein or an artery, to specific targets, then locate and detect chemical or biological compounds and report this information to the outside world," said Michael Sailor, a professor at UCSD's department of chemistry and biochemistry who led the study.

Science fiction is becoming reality everyday. What would you like these scientists to invent next?
