At the heart of every dividing cell lies a molecular process so essential that its failure echoes outward into cancer, aging, and the limits of medicine itself. Researchers at MD Anderson Cancer Center have now built a tool — RF-SIRF — that allows scientists to observe, for the first time, the precise moment and location where a cell's replication machinery reverses course under stress, and to read the molecular signals that follow. This single-cell resolution map of reversed DNA replication forks offers not just a new instrument, but a new vocabulary for understanding why some cancers resist
