Studies on people have left more questions than answers, and laboratory experiments have failed to pin down a plausible mechanism whereby weak magnetic fields could trigger the disease.

These thin magnetic films can be manipulated to trigger vastly different signals, depending upon which direction they face, allowing them to be read as the ones or zeros of basic computer code.

The thin magnetic films can be manipulated to trigger vastly different signals depending upon which direction they face (basically "north pole" and "south pole"), allowing them to be read as the ones or zeros of basic computer code.
