"CRISPR/Cas9 is a gene editing technology that's revolutionizing science at a breathtaking pace.

One of its most exciting, taboo, and controversial applications is tweaking the genes of eggs, sperm, or early embryos to alter a human life. This could one day mean the ability to create smarter or more athletic humans (yes, "designer babies"), but also the chance to knock out disease-causing genetic mutations that parents pass on to their children. We're talking about eliminating mutations linked to diseases like breast and ovarian cancers or cystic fibrosis.

Today, a team of scientists report that they have made major progress toward proving the latter is possible.

In a paper published in the prestigious journal Nature, a team led by Shoukhrat Mitalipov of Oregon Health and Science University describes how it used CRISPR/Cas9 to correct a genetic mutation that's linked to a heart disorder called hypertrophic cardiomyopathy in human embryos. And they did it without creating errors that have plagued previous attempts to edit human embryos with CRISPR.

To be clear, the new work from OHSU was a basic science experiment - the point was to test a concept, and the embryos used were never implanted into a woman's uterus.

But they were ultimately able to show that CRISPR/Cas9 could actually be used to cut the mutant gene sequence, prompt the embryos to repair the DNA with healthy copies of the gene, and eliminate the disease-causing mutation altogether. "

Has also been used to cure terminal leukemia on a little girl. Full remission.

Been following it since the beginning and made a post about this Being the end of natural evolution for humanity. So much potential for good and bad both. So groundbreaking that WHO called an emergency meeting to discuss the implications almost immediately upon verification of the tech.

This basically amounts to a word processor for DNA and can even be done cheaply by garage scientists....

NPR did a story on this today and for once it didn't sound like world ending spooky science. This will definitely be a game changer, if the moral soldiers don't get too involved.

Gene editing in the hands of garage scientists?  What could go wrong with that?  Far be it for me to take the moral high ground, but to only see the good in such a capability, and ignore the potential bad, is just short sighted.

Sometime ago I read of a researcher that stubbled upon a means by which he could stop the genetic clock that causes aging.  At first that sounds like a great discovery right?  Well he breifly pondered the complications of it and soon burned his lab to the ground.  Now he livers lives as hermit in the woods of Siberia, refusing to talk about it ever again.

Once that genie is let out of the bottle we'll never get him back in.  So is mankind really advanced enough to play god?  Can humanity be eternally benevolant and error free with such a tool?

Nothing is eternal
I don't think we have any choice but to figure out how to live with this new power.
It's not going back into the box.

But it's not "playing god".

God is what humans use to describe that in the world which they don't understand.
DNA is moving out of that category, with this we are playing human.

The genie is already out of the bottle. Too late to do anything about it in regards to stopping it.

...anb the construct of what it means to be human will either be redefined or shattered.
