"It's this incredible synergy of the flexibility, angle and extensibility of the hairs that makes it possible.". Celebrities 5. The foot of a gecko is covered with about a billion tiny hairs called spatulae. 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. Furthermore, the setae and spatulae are composed of keratin protein, much like the proteins in human hair and fingernails. Do lizards climb on beds?

The hairs, known as setae, generate a multitude of weak attractions between molecules on the two surfaces that add up to a secure foothold. These animals can sniff it out. Our toe pads! The discovery intrigued scientists, who immediately realized that if synthetic gecko-foot hairs could be made, they might be a great adhesive -- strong, glue-free, dry, reusable and, unlike suction cups, capable of working in a vacuum like outer space. Geckos can stick to surfaces because their bulbous toes are covered in hundreds of tiny microscopic hairs called setae. How do geckos scurry up walls and ceilings? When a gecko runs up a wall, the setae are stretched unevenly such that some have more force applied to them than others. We know now that the answer is in the gecko's hairy feet. Tony Gamble from the University of Minnesota has traced the evolutionary relationships of almost all gecko groups, and shown that these lizards have evolved their wall-crawling acumen many times over.

The scientistsfound thatgeckos could run sideways as quickly as they climbed upward, thanks to the ability to realign their toes. The flexibility and stretchiness of the setae help redirect the energy and make it possible for geckos to walk across surfaces at any angle, unless the surface is covered in too much moisture, in which case their sticking powers are reduced and their feet start slipping. 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. Geckos are lizards who have evolved one of the most eective adhesives known. "A lot was already known about how setae work mechanically," said NIST physicist and co-author Cherno Jaye. They have many tiny hairs per foot called setae, each of which splits off into hundreds of even smaller bristles called spatulae. Heres why each season begins twice. When asked by Hoda Kotb on The Today Show if shed ever consider going barefoot on the red carpet, Kelly admitted she wouldnt dare to. Even smaller structures at the ends of the setae, called spatulae, make such close contact with the climbing surface that electrons in both materials interact, creating a type of attraction called van der Waals forces. Although the scientists have tested only minute amounts of the material, they estimate that if its properties hold up on a larger scale, a dime-size patch of it could support 2 to 22 pounds, depending on how densely the hairs were packed.
