Within every living cell, a quiet war is waged against the entropy of existence — DNA breaks, and proteins labor to mend it. When the genes governing this repair, BRCA1 and BRCA2, are silenced by mutation, a backup protein called RAD52 steps in, allowing damaged cells to survive and proliferate into cancer. Researchers at Ohio State University have now captured the most detailed images ever made of this repair mechanism in action, revealing a 19-unit protein ring assembling and stitching broken DNA strands back together — a structural portrait that, for the first time, gives scientists a clear
