How GECKO got Stuck (and unstuck)

"Unlike most creatures, geckos don't use sticky secretions to help them hang on, it's all due to the structure of their amazing skin," says professor Anthony Russell, one of the world's leading experts on the gecko family of lizards. "Figuring out how they are able to run across ceilings and walk up windows is remarkably complex but it is getting a lot of attention because of the possible technology it could yield."

Russell says learning from how species are designed by nature to deal with environmental challenges provides key lessons for human innovations."This nano-technology has been around for over 50 million years and we are only just beginning to understand how it works," he said.
