radioactive

Nuclear power has long provided steady energy sources for everything from homes to deep space probes. Now researchers have begun developing a tiny nuclear battery the size of a penny that could provide power in a smaller, lighter, and more efficient package.

To scope out a suspected Mafia shipwreck that may hold nuclear material, Italian authorities sent in the robot.

A remote-controlled sub began filming a sunken vessel off Italy's southern coast over the weekend. That shipwreck may represent just one of 30 ships deliberately sunk in a rather sociopathic act of nuclear waste dumping.

Scrubbing sites of radiation is no easy task, not to mention costly. Aside from all the technical hurdles, the potential health hazards drive up the cost further, making it feasible in only the most necessary of cases. But researchers at the University of Missouri have found a work force that may be willing to clean up our radioactive messes on the cheap.
