    "body_text": "University of Michigan and collaborating researchers found that some CRISPR-Cas systems do more than cut viral genetic material: they regulate embedded anti-phage defense genes. The team showed a Cas protein binding regulatory DNA and switching nearby defenses on during infection. That architecture makes CRISPR a coordinator of a broader immune island, expanding the known function of the system while offering new tools for studying bacterial defense networks.",
