Scientists Do Micro-Origami, Make Tiny Drug-Delivery Package
Researchers at USC's Information Sciences Institute produced this amazing pyramid, around 30 microns across, which may one day be used to deliver precise micro- or nano-doses of medication.

The team hasn't stopped at pyramids either— they've tried flat envelopes, cubes and partial dodecahedra, but these don't close together the way the pyramid does.
