Four little feet sliding from leaf to leaf; they are so sticky that geckos can hang upside-down from a single toe. Scientists have long been fascinated by gecko feet, and in year 2002, uncovered this remarkable secret: Their precious toes adhere effortlessly to any surface through millions of nanoscale hairy structures that interact only slightly at the molecular level.
