3-Person IVF

Inheritable genetic modification (IGM, also called germline engineering) means changing the genes passed on to future generations. The genetic changes would be made in eggs, sperm or early embryos; modified genes would appear not only in the person who developed from that gamete or embryo, but also in all succeeding generations. IGM has not been tried in humans. It would be by far the most consequential type of genetic modification as it would open the door to irreversibly altering the human species.

Proposals for inheritable genetic modification in humans combine techniques involving in vitro fertilization (IVF), gene transfer, stem cells and research cloning.

First CRISPR Gene Drive in Mosquitoes Aims to Eradicate Malariaby Antonio RegaladoMIT Technology ReviewNovember 23rd, 2015Designers of a “selfish” gene able to spread among mosquitoes say it could wipe out malaria, but the scientific community is at odds over whether or not we should do it.
F.D.A. Takes Issue With the Term ‘Non-G.M.O.’by Stephanie StromThe New York TimesNovember 20th, 2015In addition to balking at "organisms," the FDA argues an industry-serving definition of “genetic modification,” comparing thousands of years of breeding techniques to extremely modern synthetic biology tools.
Scientists may soon be able to 'cut and paste' DNA to cure deadly diseases and design perfect babiesby Tanya LewisBusiness InsiderNovember 19th, 2015CRISPR gene editing tools are being proposed for a wide range of uses, many of which pose risks to ecological systems and human society.
CRISPR Gene Editing: Proofreaders and Undo Buttons, but Ever "Safe" Enough?by Elliot Hosman, Biopolitical TimesNovember 19th, 2015Recent trends include research reports of "spellcheck" and "undo" functions associated with CRISPR gene editing, and a shift toward greater caution about germline applications.
Gene Therapy: Comeback? Cost-Prohibitive?by Elliot Hosman, Biopolitical TimesNovember 19th, 2015Recent CRISPR news sometimes confuses germline modification - which should be put off limits - and gene therapy, which presents its own set of social and ethical risks to resolve before rushing to market.

Better Babiesby Nathaniel ComfortAeonNovember 17th, 2015The long and peculiar history of the designer human, from Plato’s citizen breeders to Nobel sperm banks, and the latest iteration of human genetic perfectability: CRISPR gene editing.
Why FBI and the Pentagon are afraid of gene drivesby Sharon BegleyStat NewsNovember 12th, 2015Officials from DARPA to the United Nations bioweapons office are concerned about the potential of “gene drives” to alter evolution in ways scientists can’t imagine.
Gene therapies offer dramatic promise but shocking costsby Carolyn Y. Johnson & Brady DennisThe Washington PostNovember 11th, 2015Researchers have partially restored a patient's vision by targeting a gene associated with Leber's congenital amaurosis, but the treatment could cost $500,000 per eye.
