The British Parliament's House of Lords gives final approval to a bill that earlier in February had been approved in the House of Commons, refusing to block the plan by a majority of 232, that would allow, through a modified form of in vitro fertilization (IVF), the creation of three-person babies, to treat certain mitochondrial disorders (mitochondria are parts of cells that convert nutrients into useful cellular energy to fuel vital processes), by using a very small segment of mitochondrial DNA from another woman to replace the mother's defective DNA; the U.K. is the first to authorize the still ethically controversial procedure.
