Scientists at Arizona State University have uncovered surprising new ways bacteria move, even without their usual whip-like propellers called flagella. In one study, E. coli and salmonella were found ...

Bacteria can effectively travel even without their propeller-like flagella — by “swashing” across moist surfaces using chemical currents, or by gliding along a built-in molecular conveyor belt. New ...

Bacteria that rarely tumble are likely to get trapped by obstacles, slowing dispersion. Bacteria that tumble frequently often “retrace their steps,” also slowing dispersion. Dispersion is maximized by ...
