Why do people have fingerprints?

Fingerprints do not help primates grip, as previously thought, scientists have discovered. They actually reduce the friction needed to hold onto flat surfaces. Now Dr Roland Ennos and his team at The University of Manchester are trying to find out: why do we have them?

Dr Ennos, at the University’s Faculty of Life Sciences, said: “I have been thinking about this for years and, having played around with it for a bit, realised that skin is rubbery so the ridges in fingerprints might actually reduce grip.

Gecko-Like Adhesive That Lets Go

Gecko-Like Adhesive That Lets Go 

Special tips on gecko hairs can grip and release.

Gecko feet have long been a source of inspiration to scientists striving to make superstrong, reusable adhesives. Now researchers at Carnegie Mellon University have found a new way to make such an adhesive grip and release as required, using angled microstructures. These structures mimic the tips of the hairs found on gecko toes, which give the lizard its prowess as a climber.
