press release from BAE:

"Scientists at BAE Systems’ have created an artificial surface that grips incredibly tightly without glue or pressure. A sheet of this material just over 1 metre square could be used to suspend the weight of an average family car.

Called Synthetic Gecko, the new adhesive is inspired by the gecko lizard, whose ability to scurry up vertical walls and windows has intrigued people for centuries and inspired comic book characters like Spiderman."..more there
