Researchers use CRISPR gene editing in human embryos to correct disease

Researchers have reportedly edited the genomes of human embryos using a technique called CRISPR. While scientists in China have used the same technology to genetically modify human embryos, this is believed to be the first attempt in the U.S.

The feat, led by Shoukhrat Mitalipov from Oregon Health & Science University, is viewed with trepidation by medical ethicists and some scientists, including those who developed the CRISPR technology.
