Researchers remotely control worms using magnetic nanoparticles, tomorrow: people?

Researchers at the University at Buffalo have announced they've found a way to remotely control worms using magnetic nanoparticles attached to cell membranes, and say they can cause the worms to stop moving simply by exposing the particles to a magnetic field and heating them up. This, they say, could lead to a host of medical benefits -- but if The X-Files has taught us anything, it's that remote-controlled nanotechnology can also fall into the wrong hands, and make people stop moving.
