Scientists have developed tiny elastic robots that can change shape depending on their surroundings. Modeled after bacteria and fully biocompatible, these robots optimize their movements so as to get to hard-to-reach areas of the human body. They stand to revolutionize targeted drug delivery.
Engineers have created a bacteria-filtering membrane using graphene oxide and bacterial nanocellulose. It's highly efficient, long-lasting and environmentally friendly - and could provide clean water for those in need.
