Cancer cells executed by magnet

Metal nanoparticles trigger cell's own death machinery

Evil geniuses, commence drooling. Scientists have figured out how to remotely control a cell’s self-destruction. Magnets that guide the behavior of tiny metal beads can be used to flip on a cell’s death switch, kick-starting the cell’s demolition. The approach might one day be used to kill cancer cells or orchestrate other cellular events without drugs or incisions.
