Rather than bringing people into the lab, researchers at MIT are putting tiny labs into people via a tiny implantable capsule that can track the growth of a tumor or detect heart-deterioration or even silent heart attacks from inside the body.
Tiny-fingered researchers at the University of Michigan have created this computer, the world's first complete millimeter-scale computing system. It is a prototype designed to be implanted in a human eye, to monitor internal pressure there for signs of glaucoma.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
