The pigs had been dead for an hour. The cause: cardiac arrest. But six hours after researchers at Yale University connected their bodies to a machine pumping a nutrient-rich fluid, their organs began to show signs of life again.
Though the organs didn’t suddenly start working normally, some of the cellular damage brought on by loss of blood flow after death appeared to be reversed. The pigs’ hearts emitted electrical activity. Cells in their kidneys, livers, and lungs were functioning again and showed signs of repairing themselves. The discovery, published Wednesday in the journal Nature, suggests that cell death could be delayed longer than currently possible. If those processes could
