Rockefeller scientists resolve long-standing debate over how many bacteria fight off invaders

For years, researchers have puzzled over conflicting results about the workings of type III CRISPR-Cas systems, a type of immune system found in many species of bacteria. Some data showed that this mechanism would target the virus’s DNA, while other experiments suggested it could only disable a virus once it had started replicating itself. New results suggest both mechanisms play a role. More »
