The Secrets Of Sticky Feet Revealed

Sure-footed lizards and beetles keep their feet dry to secure their grip, according to scientists. Previous studies have attributed both species' remarkable 'sticking power' to microscopic hairs on their feet.

These hairs are attracted to surfaces by the forces between molecules, creating a strong footing. Two studies now suggest that the animals 'walk on air' to overcome wet surfaces, trapping bubbles between these tiny hairs.
