It's just a little earie...

Lawrence Bonassar and others have developed methods to 3d print human ears using actual live cartelidge mixture that congealed into an ear in 15 minutes. They tested it on rats and the ears were found to retain their shape and usability after a year and integrate into the rats. There is a  potential for medical breathroughs but also the danger of abuse and misuse (looking at you Hollywood, and maybe Russia) but it leaves us feeling a bit earie
