Scientists and biologists around the world have been amazed at the small gecko's ability to climb virtually any surface since they first discovered the animal. From studying its feet, experts have inferred that materials making use of the same basic principles can be created, but exactly what triggers the grip and makes it turn “on,†and how this happens exactly have thus far eluded all scientific inquiries. Recently, scientists at the University of Calgary and Clemson University, in South Carolina, have managed to solve this long-standing puzzle.In their investigation, they have determined that the only thing triggering a gecko's solid lock on objects is gravity, and not necessarily voluntary control from the animal itself. Details of the amazing find are currently published in today's online issue of the scientific journal Proceedings of the Royal Society B. In charge of the research were UC expert Anthony Russell and Clemson scientist Tim Higham. The new study repres!
ents the latest breakthroughs in gecko adhesive investigations, the team reports. “Geckos use microscopic, hair-like filaments to attach to surfaces. Only at certain angles do they switch on their traction system, however. We are trying to understand this process, which will help in mimicking ...
