Discussion of concerns over heritable human genetic modification has spiked in 2015. This dialogue is a good thing, but is it in a sense too late?

Human cloning is not so far-fetched any more. Cloning of the Star Wars variety where new copies of people (although they would be babies, not adults of course at first) are produced is something I believe that we’ll see in the next 1-2 decades. Why would anyone bother to clone? Fame. Money. Vanity. There are

The poll I put up asking people their #1 top priority for FDA reform drew relatively big numbers of respondents. Speeding up clinical trials was clearly way out in front at #1. Expanding compassionate use was #2. These were followed by changing policy to no longer define lab-grown stem cells as drugs and FDA being
