Ever wonder how lizards like Geckos can walk up walls and even across the ceiling? Is it sticky feet, anti-gravity, or what?
Researchers at Oregon State University have developed a model that explains how geckos, as well as spiders and some insects, can run up and down walls, cling to ceilings, and seemingly defy gravity with such effortless grace.

This ability, outlined today in the Journal of Applied Physics, is a remarkable mechanism in the toes of geckos that uses tiny, branched hairs called “seta” that can instantly turn their stickiness on and off, and even “unstick” their feet without using any energy.
