In the long struggle between human medicine and microbial life, researchers at Israel's Technion have illuminated a hidden chapter: bacteria do not merely stumble upon resistance, they actively amplify the very genes that protect them, producing dozens of copies with startling speed. Dr. Idan Yelin and Professor Roy Kishony, publishing in Nature Microbiology, have named and mapped this mechanism — a molecular bridge connecting distant regions of bacterial DNA — revealing that adaptation may be occurring even within the span of a routine treatment course. The discovery does not yet change how m
