Researchers have discovered a way to program cells to inhibit CRISPR-Cas9 activity. 'Anti-CRISPR' proteins had previously been isolated from viruses that infect bacteria, but now scientists report three families of proteins that turn off CRISPR systems specifically used for gene editing. The work offers a new strategy to prevent CRISPR-Cas9 technology from making unwanted changes.
