Chinese Scientists Claim To Have Genetically Modified Human Embryos 182

Posted by samzenpus from the super-babies dept.
Annanag writes: There were rumours — but now it's been confirmed. Chinese scientists have attempted the ethically questionable feat of genetically modifying human embryos. The scientists try to head off ethical concerns by using 'non-viable' embryos, which cannot result in a live birth, obtained from local fertility clinics. The study is a landmark — but also a cautionary tale.

        This stuff is all good as long as its well documented which genes were changed and why. Because copyright (or patents) (or even (worst of all) trade secrets) on human DNA is the worst thing that can happen to our human society. We don't want only the well born to have better genes. But of course this won't happen. There will be a strong gene copyright lobby, and it will demand DNA to be copyrightable, to make research pay off.

        Also, we should think of the possible pressure future parents may be in, in giving their children the best genes. Perhaps one day (rather sooner than later) we can change genes of living humans, too, e.g. with viruses, and then at least you can revide your parent's choices about your body.

          The takeaway is that sooner or later, there is going to be widespread genetic modification. Many of us have known this for a very long time, some suspected, some hoped it will not happen. It will, just like we will have autonomous robots doing all manner of things, one day (all vehicles, maybe in my lifetime).

          > This stuff is all good as long as its well documented which genes were changed and why

          The impetus is not to hope a pharma company will disclose information, but to start baking in the expectation in all strata of society as a normal process. Politics, capitalist endeavors, technology, and copyright is BAD for our future society. To put it simply, a struggle against the secret vs the open is BAD for society. Tuskeegee, concentration camps, and other horrifics were only possible because it's still accepted that 'state secrets' or even "personal liberty" is tied to exposed information, as if there is an invisible-acceptable moral line. You have to get people willing to listen and accept the opposite of what the US (and to an extent) European citizens' expectation of privacy allow. Would I like my home address available for anyone? Of course not. Mostly because there aren't enough protections/retributions and society EXPECTS you to be punished for having that information exposed. What we want has to change. That level of openness is something humanity needs to build toward, if we want to secure against potential abuses. Props to eu for making strides. The method of sticking our head in the sand, only to look up when there's a rumbling, will never be effective and will continue to be abused by those who understand it (we'll just spin the story).

          I don't know how to get there, but we will or we will die from someone making a big enough mistake with genetics. I'll probably be long dead, but it bothers me to have such certainty about these issues and so frustrated when there's a suggestion that more forced oversight will satisfy.

      Well, if you read the article (I know, I know... reading them is overrated), you would have read that they were trying to modify a gene that can mutate to cause a disease. Of the 71 of 86 embryos that survived their tinkering, 54 were tested to reveal that only 28 were successfully spliced and only a fraction of those contained the replacement genetic material. As a bonus failure, they induced a number of mutations elsewhere in the genes.

      They concluded that it was a colossal failure that would result in a seriously messed up offspring and that technology is not ready for that application yet. (No consideration of if just THEIR technique was poor.) With the appropriate spin (do not try this at home), they were able to get their results published in a high citation journal.
