Crispr Study Reveals Surprising Role of Cas9 as a Guardian of Bacterial Defense

New research from the lab of Yan Zhang, Ph.D., at the University of Michigan sheds light on how bacteria use the CRISPR-Cas9 system to defend against viruses. By studying how bacteria form new immune memories, Zhang and her team uncovered an unexpected twist in how this powerful system works. The study offers surprising new insights into one of science’s most powerful tools.
