Mankind has been fascinated with geckos for centuries, but we still don’t understand how the gecko achieves the adhesive strength with which they climb and cling to nearly any surface.
Found in warm regions of the world, geckos are extremely capable of climbing up steep, smooth surfaces. To do so, they employ an adhesive system — a key evolutionary innovation that facilitates climbing vertically, and even in inverted positions.
The uncanny ability of geckos to adhere to nearly any surface and even walk on ceilings is the result of a biological mechanism in their toes that the lizards can instantly turn on or off, according to new research appearing in the latest edition of the Journal of Applied Physics.
Researchers, studying the self-cleaning and reusable capabilities of a gecko’s foot hair, have speculated how commonly-used sticky substances could benefit from the animal’s natural adhesive properties.
For years, biologists have been amazed by the power of gecko feet, which let these 5-ounce lizards produce an adhesive force roughly equivalent to carrying nine pounds up a wall without slipping.
HUNTSVILLE, Ala., June 29, 2011 /PRNewswire/ -- Tec-Masters, Inc. (TMI) has been awarded a $24.8M five-year contract to provide Systems Engineering and Technical Assistance (SETA) support to the Fires Center of Excellence at Ft. Sill, Oklahoma.
The arrays of fine adhesive hairs or â€˜setaeâ€™ on the foot pads of many insects, lizards and spiders give them the ability to climb almost any natural surface.
Human adhesives are famed for their fallibility. Gooey glues soon lose their grip, are easily contaminated and leave residues behind. But not gecko feet. Geckos can cling on repeatedly to the smoothest surfaces thanks to the self-cleaning microscopic spatula-shaped hairs (setae) that coat the soles of their feet.
Holarchaea novaeseelandiae is one of only two described species in the genus Holarchaea and is native to New Zealand. This spider is very small at less than 1.5 millimeters long. It is shiny black, brown, olive, or beige in color. The head region is clearly distinguished, features eight eyes, and a few setae. It occurs only in the forests of New Zealand. It lives in humid environments and has been found on moss, ferns, and plant litter. Image Caption: adult Holarchaea sp. from New...
