The amazing octopus continues to astonish scientists and the public. Every facet of this invertebrate has surprised researchers, from its extremely rapid ability to change color and disappear into the background, to its amazing intelligence.

Namib desert beetles collect faint water droplets on their exquisitely designed outer surfaces so they can survive in their dry environments. And polar bears keep a tight grip on smooth ice using precisely designed footpads. Engineers have copied these exquisite designs to make useful tools.

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.

The Wright brothers studied wing structures of seabirds before building their first airplane, and the first helicopter is said to have been inspired by dragonfly flight. Today, inventors continue this tradition, focusing on bio-inspired flight sensors. A series of telling admissions in a recent summary of state-of-the-art research leave no doubt about the origins of flight-ready sensors.
