Geckos can stick to surfaces because their bulbous toes are covered in hundreds of tiny microscopic hairs called setae. Now they have a clearer picture of the molecular structures that give the animal its grip. In gecko toes, for example, only a fraction of the setae are in close contact with the surface, and those that are don't share the load equally among themselves. NIST physicists Dan Fischer (left) and Cherno Jaye at the NIST synchrotron microscope located at U.S. Department of Energys Brookhaven National Laboratory. The American singer, actress, and television personality showed what can happen if you wear uncomfortable shoes when she went bar hopping in London. K- faulty punctuation: restrictive or nonrestrictive. When the gecko plants its toes, the setae extend so that their tips point away from the body. He pieced the genealogy together with Eli Greenbaum from Villanova University, by analysing six genes from 244 gecko species. Do you think she should continue wearing open-toe shoes? The connection breaks when the gecko shifts its foot enough to change the angle between the hairs and the surface. The gray squiggles represent lipid molecules. For people in many ancient societies, work was only a means of survival rather than a way to improve your standard Faye Marsay's jacked up feet in Christian Louboutin sandals (Credit: FayesVision / WENN) 10.

Follow us @livescience, Facebook& Google+. Geckos have arrays of millions of microscopic hairs, or setae, on the bottoms of their feet. When does spring start? More than a decade of research and engineering has culminated in gecko tape: a re-useable adhesive that has a structured surface similar to that of geckos and that outperforms the usual sticky tape. Each seta ends in an array of nanostructures, called spatulae,that function as a dry adhesive. There are around 1,450 species of geckos, and around 40 per cent have non-stick feet. Along with colleagues in Oregon, Denmark, and Germany, researchers at the National Institute of Standards and Technology (NIST) took a closer look at those structures using high-energy synchrotron, revealing that they are coated with an ultra-thin layer of lipid molecules in an upright orientation, according to a recent paper published in the journal Biology Letters. When a gecko jumps to another surface or quickly changes direction to escape a predator, its toe hairs must absorb huge amounts of energy and redirect it. Ballet dancers who practice the pointe technique in pointy shoes often experience foot pain and, in some cases, foot damage. Each of its four feet has about five hundred . The scaling problem stems in part from the fact that loads don't distribute uniformly across large areas of adhesives, report researchers from Stanford University in Palo Alto, California, in a study published online today in the Journal of the Royal Society Interface. The earliest days of the dinosaurs found the gecko amongst the animals that emerged.

Katy Perry grasping the edge of her sandals with her toes (Credit: Andres Otero / WENN). But therein lies the beauty of the system: It could easily adapt to different situations, just by replacing the adhesive tiles with other types of geckolike adhesivesfor example, adhesives that self-clean like real gecko hairs.

Pushing the flat side down produced a larger surface area for sticking to a glass surface. "I'm a little hesitant on going too fast," Professor Dhinojwala said.

Anne Hathaway. graduates, many of whom have gone on to earn national recognition. Its feet are so sticky that it could hang from smooth glass by one toe. Kelly Gale shows off her feet in black sandals (Credit: Judy Eddy / WENN). Thus while walking or running on horizontal or vertical walls, a lizard curls and uncurls its does thus creating a suction pressure that enables it to cling onto the walls. The hairs, known as setae, generate a multitude of weak attractions between molecules on the two surfaces that add up to a secure foothold. The sticky setae evolved from tiny hair-like growths called spinules, which cover the body of all geckos and are thought to help them shed their skin. The system makes it possible for geckos to stick and unstick their feet so quickly that they can scurry across surfaces at 20 body lengths per second. She has had some fantastic shoe moments, though.
