Whoever said the human brain is the most highly organized collection of matter in the universe was more correct than they could have known. New research modeled tiny structures within nerve cells and discovered a clever tactic brains use to increase computing power while maximizing energy efficiency. Its design could form the basis of a whole new and improved class of computer.

Increasing numbers of innovative researchers borrow from biology when they examine and incorporate living systems into man-made designs. We know how man-made designs originate— people design them. But what about living designs? Two recent biomimicry research programs let slip major logic errors when accounting for the origin of the creatures they copy: the seahorse and kangaroo.
