  "textContent": "Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and partially break apart to bind key DNA sequences that activate division genes. Using cryo-electron microscopy, scientists captured this interaction in remarkable detail. The mechanism appears to be widespread across bacteria, offering a new window into how microbes regulate growth.",
