Bioethicists Approve '3 Parent' Embryos

The Washington Post (Feb. 3, 2016): Ethicists approve ‘3 parent’ embryos to stop diseases, but congressional ban remains, by Joel Achenbach: 

An advisory panel called together by the US Food and Drug Administration concluded, this week, that it is ethically permissible to proceed with in-vitro fertilization that combines the DNA of three parents to form an embryo. The panel, made up of scientists and bioethicists, approved a procedure called mitochondrial replacement techniques (MRT), but advises caution in its use. 

MRT replaces the nucleus of a donor's egg with the mother's nucleus and then fertilizes the egg with the father's sperm. The procedure guards against certain diseases that can be passed down from mother to child through the egg's mitochondria. 

Though the procedure has been approved by the House of Lords in the UK, it is currently on hold in the US due to a congressional ban.
