What is it about?
Cells of the surface-dwelling social bacterium Myxococcus xanthus move coordinately in large groups where individual cells seldom reverse their moving direction. The report by Zhou and Nan shows that exopolysaccharides (EPS) inhibit cellular reversal in a concentration dependent manner. Thus, high concentration of EPS in cell groups is a self-produced signal that promotes group motion by inhibiting cellular reversals.
