For the first time, a breakthrough technique called CRISPR has been used to treat a genetic disease inside a living mammal. In three independent papers, published in the journal Science, U.S. scientists snipped out defective DNA in mice with the disease—the first time this tool, called CRISPR, has been used to treat any genetic disease inside a living mammal—and restored some of their muscle function.

Cam, this is great news and an amazing piece of technology. Thanks for posting.

In the news today was a story that the first "editing" of human DNA to remove a disease was accomplished in human embryos. In this case the disease was a blood disorder called beta-thalassemia.
