Chinese scientists do genetic experiments with human embryos
What could possibly go wrong? A Chinese team of scientists have been experimenting with genetically manipulating the human embryo to see if they can prevent a genetic blood disorder.
The team attempted to modify the gene responsible for β-thalassaemia, a potentially fatal blood disorder, using a gene-editing technique known as CRISPR/Cas9. The researchers say that their results reveal serious obstacles to using the method in medical applications. “I believe this is the first report of CRISPR/Cas9 applied to human pre-implantation embryos and as such the study is a landmark, as well as a cautionary tale,” says George Daley, a stem-cell biologist at Harvard Medical School in Boston. “Their study should be a stern warning to any practitioner who thinks the technology is ready for testing to eradicate disease genes.”
They not only found the technique unreliable in curing the genetic disease, it also produced many more unpredicted mutations.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

The needs of the many over the one?
::shudder::
Well it looks like they tried to do it as ethically as possible.
And someone had to try first.
I am actually surprised they chose to use already genetically malformed cells for the test subjects in the first place. That would toss in some variations to the mix they couldn’t account for accurately.
The only other viable but unused way to test a human embryo for genetic abnormalities is to spit it(make a twin) and test one while saving the other. Using this method abnormal ones could be thrown out before implantation.
But again this leaves the ethical question of the destruction of the twin. And it doesn’t always leave a viable twin for implantation. Sometimes the physical splitting alters or even stops the further formation of the embryo.
Just finished reading “Friday” by Heinlein and couldn’t help but think — So, it has begun…
Heinlein has another story on the topic – “Jerry was a Man”
