Teflon Beats Gecko - Temporarily

Can nature beat science? This is an open question but it will be put to the test. Teflon is a material created by scientists. It does not occur naturally. Will it stand the test and be unique, unfettered by mother nature?

Geckos can run along many surfaces, whether vertical or upside-down. Their toes are covered in in rows of keratin ridges called lamellae. They are like very fine hairs that attach to just about anything.

Students at the University of Akron's Auburn Science Centre tested the ability of geckos to run along vertical teflon sheets. And yes, they could not cross it! By adding water, however, they ran along it quite happily.

Apparently, the presence of moisture is a must for geckos to get around. Any surface that repels water is playground for geckos. An adhesive has been developed that will stick things together underwater based on research done on this interesting little creature.
