Sweden’s 100,000-Year Nuclear Puzzle: Scientists Develop Strategy to Preserve Crucial Waste Repository Information

A (light green) bacterial cell detects a source of stress and becomes activated (dark green). It then produces alarmones (depicted as red triangles) and can transmit them to neighboring cells via cell-to-cell contact (black arrows). As the source of stress arrives, the percentage of activated cells increases, converting unstressed neighboring cells and triggering the stress response mechanism.
