Bacteria have evolved powerful defenses against the viruses that prey on them. The most famous such defense, CRISPR-Cas9—a kind of molecular scissor that can snip away at viral DNA—was adapted to create the first FDA-approved genetic editing tool. But Luciano Marraffini, who helped identify CRISPR’s potential for genetic engineering, keeps finding more. Most recently, Marraffini...
