Microoxen

There’s been a great deal of talk in Nanotechnology about building super-tiny motors to power assorted cell-sized machines, but a group of scientists now argue that it might make more sense to use motors that already exist, perfectly functional, inside living cells. Instead of trying to build a car, build a cart: BBC: Cells made to haul tiny cargoes.
Their delightful name for this innovation: Microoxen!
