If you're in the market for a replacement ear, how about one of these wonderful little 3D printed ones?
While researchers at Cornell University in Ithaca, New York, have demonstrated a hydrogel gel-based 3D printed ear before, these little things from Hangzhou Dianzi University in China are made up living tissue. Created using the Regenovo 3D priner, they're made from layers and layers of live cells.
They might look a little... anemic, and for that matter, small, but they should, in theory, be perfectly grafted onto living creatures. If only van Gogh was alive today. [New Scientist]
