The Gene-Edited Babies And CRISPR-Cas9 Controversy, Explained


Outrage continues to grow over the news that Chinese scientist He Jiankui claims to have used gene-editing technology called CRISPR-Cas9 to create embryos that he then transferred into a woman, resulting in the birth of twin girls. 

His stated goal was to give these girls genetic immunity to HIV, but experts say that he unnecessarily put their lives in danger by using a tool that could cause unwanted and unforeseen alterations in other parts of their genetic code, in ways that could be passed down to the girls’ future descendants.
