[2] When a gecko is climbing on a hydrophilic surface, capillary forces combine with van der Waals forces to keep the gecko in place. Setae provide sticking power because they are flexible and assume the microscopic contours of whatever surface the gecko is climbing. The researchers showed that the keratin fibers are aligned in the direction of the setae, which might help them resist abrasion. Reflection Paper: Ganito Kami Noon, Paano Kayo Ngayon? Gorb, T. Weidner. What type of force can explain how a gecko climbs up a wall?

J- faulty reference ( pronoun) Geckos are renowned for the sticky feet that enable them to climb a variety of surfaces. An illustration of a gecko spatula, a nanometer-scale structure on the animals toes that contribute to its grip. Essentially, the tufts of tiny hairs on gecko feet get so close to the contours in walls and ceilings thatelectrons from the gecko hair molecules and electrons from the wall molecules interact with each other and create an electromagnetic attraction. Few issues of public policy are as likely to provoke widespread interest as that involving possible danger to the health For people in many ancient societies, work was only a means of survival rather than a way to improve your standard Many gecko groups lost these adaptations when they changed their lifestyles, from wall-scuttling to, say, burrowing in sand.
