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.

In the past, scientists have explored killing cancer using tiny iron-containing nanoparticles that latch onto malignant cells and...
