Shattered bones pose a difficult problem for surgeons, who currently must use tiny screws and plates to hold fragments in place long enough for the break to heal. But a new glue, which has the sticking power to adhere to bone, could one day help orthopedic surgeons fix difficult breaks, researchers announced today at the American Chemical Society conference in Washington, DC.

Much Better Than A Sticky Pickle

What’s better than duct-tape? Magnetic duct-tape!

Gecko-Like Adhesive That Lets Go 

Special tips on gecko hairs can grip and release.

Gecko feet have long been a source of inspiration to scientists striving to make superstrong, reusable adhesives. Now researchers at Carnegie Mellon University have found a new way to make such an adhesive grip and release as required, using angled microstructures. These structures mimic the tips of the hairs found on gecko toes, which give the lizard its prowess as a climber.
