Simple bacteria have an immune system with a memory, which allows them to destroy invading viruses they have encountered in the past. In just two years, scientists have discovered how to repurpose the simple virus-shredding technique used by bacteria in more complicated creatures, a feat that is now revolutionizing research across the Boston area and beyond.
