How Gene Editing Works

With the discovery of a surprising immune response in E coli bacteria, we are facing a new era of freedom from genetic mutations that lead to disease by simply and precisely editing our genes. But there is also a potential dark side to gene editing.

MSNBC reported yesterday that a fertility clinic in Los Angeles (shocker) is now allowing prospective parents to pick and choose certain physical characteristics of their baby-to-be. Yes, this means that if you have the cash, you can order a baby with blonde hair and blue eyes if you so desire. The clinic claims it's already gotten half a dozen requests for these "designer babies" and expects to roll out the first line next year. The method used to screen for these characteristics is called preimplantation genetic diagnosis (PGD). It's been used since 1990 to help couples avoid passing on serious genetic diseases to their babies. It's also been used to help create "savior siblings" -- babies that are a good genetic match for older brothers or sisters that might need some blood or bone marrow, for instance.
