"This is one of the most exciting things I've seen in years," says biomechanist Kellar Autumn of Lewis & Clark College in Portland, Oregon, who was not involved with the study. Scientists have recreated geckolike adhesion using silicones, plastics, carbon nanotubes, and other materialsbut they've run into a scaling problem: The stickiness diminishes when the size of the adhesive exceeds a few square centimeters, severely limiting its practical applications. "This has been a real dream of mine.". K- faulty punctuation: restrictive or nonrestrictive. Scientists already understood the mechanics of gecko adhesion. Evidence that gecko setae are coated with an ordered nanometer-thin lipid film. Reflection Paper: Ganito Kami Noon, Paano Kayo Ngayon?

Coupled with that, smaller lizards are sometimes too curious so they may climb on your bed without even knowing what they are doing or looking for. As a result, the tiny hairs touch so much surface area so closely that weak forces of attraction between molecules in the hairs and in whatever surface the animal is walking on add up and become sufficient to let the gecko hang on. Biologists from the University of California, Berkeley, and Nanjing University of Aeronautics and Astronautics observed geckos running horizontally along walls to learn how they use their five toes to compensate for different types of surfaces without slowing down. Correct any antecedent errors. To transform spinules into setae, its a simple matter of lengthening them and flaring their tips out into split ends.
