Octopi are well-known for their grabby tentacles. Now, scientists have developed a material that mimics the sucker discs on those tentacles. It could be used for adhesive pads that are reversible, reusable, fast-acting, and effective even in wet conditions.

Researchers at the Korea Institute of Science and Technology (KIST) has developed a graphene substitute from plastic that offers the benefits of graphene for use in solar cells and semiconductor chips, but is easy to mass-produce.
