Frog's Sticky Tongue Could Lead to Adhesive Innovations

From telescopes inspired by lobster eyes that see more of space, to new Japanese high-speed trains modeled after Kingfisher beaks, engineers who take cues from nature to fuel innovation are turning their attention to the sticky tongues of frogs. Thomas Kleinteich, of Germany's Kiel University, wanted to know how the sticky tongues of frogs compare to the feet of the much-studied gecko, which can blaze a trail up a wall or race upside down across a ceiling.
