So why do we immediately disbelieve these claims?
First there is the publication style, making it seem like written-for-idiots clickbait.
Second, we have been through this with PCR and 30 years of basically the same claims. Effectively these techniques have as their only successes those modifications of genomes that made plants less productive, e.g. either needing more chemicals or needing purchasing seeds, because that means you could charge the farmers more.
None of all this tech has been able to reproduce anything like the feats of e.g. the ancient american agricultural scientists.
I like to keep an open mind so I'm not going to fully discount crispr. However it's totally clear nothing useful will come from this while the research is paid for in fiat.
Critics Lash Out At Chinese Scientists Who Edited DNA In Human EmbryosFor the first time, scientists have edited DNA in human embryos, a highly controversial step long considered off limits.
Junjiu Huang and his colleagues at the Sun Yat-sen University in Guangzhou, China, performed a series of experiments involving 86 human embryos to see if they could make changes in a gene known as HBB, which causes the sometimes fatal blood disorder beta-thalassemia.
The report, in the journal Protein & Cell, was immediately condemned by other scientists and watchdog groups, who argue the research is unsafe, premature and raises disturbing ethical concerns.
"No researcher should have the moral warrant to flout the globally widespread policy agreement against modifying the human germline," Marcy Darnovsky of the Center for Genetics and Society, a watchdog group, wrote in an email to Shots. "This paper demonstrates the enormous safety risks that any such attempt would entail, and underlines the urgency of working to forestall other such efforts. The social dangers of creating genetically modified human beings cannot be overstated."
George Daley, a stem cell researcher at Harvard, agreed.
"Their data reinforces the wisdom of the calls for a moratorium on any clinical practice of embryo gene editing, because current methods are too inefficient and unsafe," he wrote in an email. "Further, there needs to be careful consideration not only of the safety but also of the social and ethical implications of applying this technology to alter our germ lines."
Scientists have been able to manipulate DNA for years. But it's long been considered taboo to make changes in the DNA in a human egg, sperm or embryo because those changes could become a permanent part of the human genetic blueprint. One concern is that it would be unsafe: Scientists could make a mistake, which could introduce a new disease that would be passed down for generations. And there's also fears it this could lead to socially troubling developments, such as "designer babies," in which parents can pick and choose the traits of their children.
