Harder, Better, CRISPR, Stronger

The first known attempt at creating genetically modified human embryos in the United States has been carried out by a team of researchers in Portland, Oregon. The effort, led by Shoukhrat Mitalipov of Oregon Health and Science University, involved changing the DNA of a large number of one-cell embryos with the gene-editing technique CRISPR. Anthony and Jeff discuss designer babies, and what this might mean for the future.
