Biologists have been mixing the DNA of different animals since the 1970s, but the idea of injecting the genes of animals into humans remains taboo. Called transgenics, it's a practice that could cure illness in the future — and eventually reshape our species. Here's what you need to know about it.
The hearts of genetically modified pigs could soon be transplanted into humans. A research team, who tweaked the DNA of pigs to make the organ more compatible to humans, grafted a pig heart into a baboon more than a year ago — and it's still doing fine.
Two scientists at the Thomas E. Starzl Transplantation Institute at the University of Pittsburgh discussed the state of xenotransplantation—the use of cells, organs, or tissue from one animal in another—in a review in The Lancet.
