In the 1950s and 1960s, scientists cracked the genetic code — a breakthrough that still inspires awe and wonder for revealing the essential, powerful machinery of life.
Now science has given us something new to think about: How sacrosanct is that code? Is it OK to manipulate the unique DNA each of us carry?
Last week, a paper in Nature showed just how far scientists have opened the doors on DNA over the last decades, edging from appreciative observers to cautious participants. A global research effort lead by a team at Oregon Health & Science University used a fairly recent technology called CRISPR to edit a defective gene inside viable human embryos.
