    Researchers Discover 10 New Immune Systems in Bacteria

    Bacteria have been defending themselves from phages—viruses that attack bacterial cells—for billions of years, and unlocking the immune mechanisms they use to protect themselves has led to the development of powerful molecular biology tools such as restriction enzymes and CRISPR-Cas9. Now, researchers report in Science today (January 25) that they have discovered 10 more immune systems that bacteria use to protect themselves against phages and plasmids, opening up the possibility to add new tools to the molecular biology toolbox.
