A Chinese scientist claims to have created the world’s first genetically-engineered babies. He used CRISPR, a revolutionary gene-editing technology, to deactivate a gene in their DNA linked to HIV infection. Editing human DNA in this way could save lives, but many researchers fear unintended consequences.
Following is a transcript of the video:
In 2011, scientists created glow-in-the-dark cats. The researchers took a gene from a glowing jellyfish and inserted it into the unfertilized eggs of house cats. It was a neat trick, but they had a bigger goal in mind. They also made the cats more likely to be resistant to a feline form of AIDS by, again, manipulating their DNA. And cats aren’t that different than humans. In fact, we share around 90 percent of our DNA with them.
So why can’t we engineer humans in the same way? Well, we can – engineer ourselves to be resistant to life-threatening illnesses, that is. In fact, one scientist claims that he’s genetically engineered two babies using a r
