                                    Inspired by geckos' sticky feet, MIT scientists have developed a bandage that could soon be used in place of stitches or staples during surgery. The waterproof material, coated with a sugar-based adhesive that has the nano-scale hills and valleys found on lizard feet, is flexible enough to be used on...
