New research is confounding conventional wisdom about life and death. 

Researchers at Yale University used a new technology to restore cells in some organs of pigs that had just died, bringing the animals’ cells back to function. The findings, which were published Wednesday in the scientific journal Nature, raise profound ethical questions about how medicine defines death but also teases new possibilities for the collection of human organs for transplant.

“My eyes went wide,” Brendan Parent, an assistant professor of bioethics at the NYU Grossman School of Medicine, said about the moment he first read the new findings. “My brain went to all the crazy places we could go in 20 or 30 years.” Parent was not involved in the study, but was asked by Nature to write a commentary discussing the implications of the new technology.
