How to (Really) Engineer a Human Baby

November 30, 2015

(MIT Technology Review) – How would you engineer a baby? I mean really, actually do it. Last April, Chinese researchers reported that they had tried genetically editing human embryos for the first time to correct a disease gene. Out of more than 80 embryos, however, only a handful came out correctly. In the rest, the gene didn’t get fixed properly, or they ended up with unintended alterations to their DNA. The scientific community pounced on the problems with a collective phew. Don’t worry, they said, it’s not even practical. Not yet.
