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.

The idea of xenotransplantation, while a good near-term solution, is not likely to stand the test of time. Aside from ethical considerations, the practice will soon be overshadowed by advances in regenerative medicine.
