Research sheds new light on wall-climbing critters: "Few things are as disconcerting, or as curious, as the sight of a gecko or spider skittering effortlessly upside down along the ceiling. This ability is known to be facilitated by microscopic hairs or 'setae' on the footpads of insects and mammals and a better understanding of their function could lead to advances in synthetic adhesives, wall climbing robots and yes, even the the holy-grail of the spiderman suit."
