Printing a human ear sounds like a far away application of modern biology, however it is here a lot sooner than we might have thought! Thanks to researchers in the Bonassar lab at Cornell University and utilising 3D printing technology this technology is now a reality. The printers work by layering cells into a complex 3D lattice, where they can grow into a living ear. It can only be a short time before we see other body parts also being created in a similar fashion to this! Check out a video about this work after the break or read more here.
