Scientists have long dreamed of creating microscopic swimmers capable of ferrying drugs to precise locations in a cell or helping assemble infinitesimal machines. Now Iranian physicists have proposed a simple design modeled on the slow-moving earthworm. Their â€nano-swimmerâ€ would consist of three spheres connected in a row by two rods. When moving, the rods would contract in sequence-first the rear one, then the front; next they would expand in reverse order.
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.
