Pope Francis Said to Bless Human-Animal Chimeras

January 27, 2016: Read article in MIT Technology Review.

Juan Carlos Izpisua Belmonte, a prominent stem-cell biologist, is engaged in efforts to grow human tissue inside of farm animals such as pigs, sheep, and cows. This type of research is sensitive because scientists have to inject human stem cells into early-stage animal embryos, then try to implant the embryos into surrogate animals in the hopes of producing fully-formed human organs for transplant. Belmonte told Scientific American that Pope Francis has personally blessed this ethically questionable research which may blur the line between human and animal.
