Scientists recover 'severely' damaged human lungs by attaching them to pigs

Researchers have recovered donated lungs, deemed too damaged to be used in transplants, by connecting them to the circulatory system of a living pig. A study by Columbia Engineering and Vanderbilt University showed that "severely" damaged lungs that couldn't be salvaged by standard methods were recovered during 24 hours on their cross-circulation platform. They next plan to use medical-grade pigs.
