Self-assembling material could produce artificial veins
Most attempts at creating artificial veins don't come close to replicating organic processes, but researchers at the Queen Mary University of London might change that. They've developed a technique that makes proteins and peptides self-assemble into tubular shapes that could stand in as arteries, veins and similar structures. There's no 3D printing or moulds involved -- you only need to guide the material as it builds itself. It can even grow and heal, so you're not stuck if it needs improvements.
