Scientists generate human-monkey chimeric embryos

Wait , wait wait....
Interspecies chimeras in mammals have been made since the 1970s, when they were generated in rodents and used to study early developmental processes. The advance that made the current study possible came last year when this study's collaborating team -- led by Weizhi Ji of Kunming University of Science and Technology in Yunnan, China -- generated technology that allowed monkey embryos to stay alive and grow outside the body for an extended period of time.
In the current study, six days after the monkey embryos had been created, each one was injected with 25 human cells. The cells were from an induced pluripotent cell line known as extended pluripotent stem cells, which have the potential to contribute to both embryonic and extra-embryonic tissues. After one day, human cells were detected in 132 embryos. After 10 days, 103 of the chimeric embryos were still developing. Survival soon began declining, and by day 19, only three chimeras were still alive. Importantly, though, the percentage of human cells in the embryos remained high throughout the time they continued to grow.
Can't see how anything could go wrong here

Can the world just agree to nuke China, before they end up getting us all killed?

Chinese people don’t have similar religious inhibitions to Westerners. Only 3% of Chinese describe themselves as religious while 53% of Americans do.

Does that make them smarter than we are?

Maybe they are more into evolution, and not into the woman came from a rib, Garden of Eden type deal ?

That makes them oppressed...

I would argue that all of “Gods children “ are equally oppressed. Ironically, by the God they serve.
