Gene scissors switch off with built-in timer

Researchers discovered a timer integrated into CRISPR gene scissors that enables them to switch themselves off after a viral attack. The CalpL protein triggers a signaling cascade to help the cell survive the viral attack, but breaking down cyclic oligoadenylates regulates the immune response and returns the cell to normal conditions.
