China's Bold Push into Genetically Customized Animals

- 88e282102ae2e5b 11y agoA recent attempt by Chinese scientists to modify human embryos showed serious problems with that strategy. From the paper [1]: "...the efficiency of homologous recombination directed repair...was low and the edited embryos were mosaic. Off-target cleavage was also apparent... Furthermore, the endogenous delta-globin gene (HBD), which is homologous to HBB, competed with exogenous donor oligos to act as the repair template, leading to untoward mutations. Our data also indicated that repair of the HBB locus in these embryos occurred preferentially through the non-crossover HDR pathway. Taken together, our work highlights the pressing need to further improve the fidelity and specificity of the CRISPR/Cas9 platform, a prerequisite for any clinical applications of CRSIPR/Cas9-mediated editing." Maybe we'll find a system that's better or we'll modify Cas9 somehow to stop these off-target effects, but for now it's not really viable.

- rtl49 11y agoThis is one of several areas where scruples would put the West at a significant competitive disadvantage in the years to come. I'm not sure whether there's any palatable solution. Can we see to it that we do not become monsters in the process of fighting them? I have doubts. I think concern for ethics in scientific research will fall by the wayside in the face of a serious challenge to the current distribution of global power. If the Chinese begin engineering genetically superior soldiers (assuming such a thing remains sensible in an era of drones and robotic ground forces), the West will do the same. What an unfortunate vision of the future.
- x5n1 11y agoI am sure China is already doing it... and the West is not that far behind. They will more likely than not justify it by creating a hybrid animal that won't quite be a human and therefore deal with the concerns that way. They'll call them Gorilla Guerrillas or 大猩猩游击队
- transfire 11y agoUnfortunately, as the article states, China has these ethical issues too. When I hear all the fear mongering around these new technologies it just reminds me of puritans and witch burnings. There is so much potential here to make the world a better place, and we still let "fear of god" hold us back.
- JamesBarney 11y agoMy biggest fear for genetic engineering isn't the making of super soldiers via increases in strength, intelligence, and beauty. It's breeding well-behaved children. I think most parents want well-behaved children that listen to their parents. I also believe that many times society has leapt forward because of revolutions spurred on by deviants and trouble makers who were probably not model kids.
