Can biomimicry improve how we do everything? From chain-building weaver ants to colour-changing cephalopods, nature offers an incredible source of inspiration for inventors. But some believe it has its limits.

Better together: Weaver ants work together effectively through a remarkable system of physical cooperation and chemical communication, so an entire colony acts as a single, highly-efficient organism. Glossary
