Getting a viable organ transplant is a real problem. There are only so many donors to go around, and the organs that do show up might be tossed out if they're not used within a matter of hours. The US government isn't satisfied with this state of affairs, though. As part of a broader effort to reduce organ waiting lists, it's unveiling $160 million in public-private investments for a new Advanced Tissue Biofabrication Manufacturing Innovation Institute. The organization will develop techniques for repairing and replacing tissues that could lead to artificial organs. Simply speaking, you wouldn't need someone to donate an organ -- doctors could either fix damaged parts or transplant an artificial organ created on demand.
