Our latest work is out in PNAS!🎉
We show that nonequilibrium polysome dynamics help drive sister chromosomes apart. The closing division septum also contributes via steric interactions.👇

The newfound strategy seen in C. matruchotii might help oral bacteria recover lost territory after each eviction by toothbrushing.
