Bacteria mix it up at the microscopic level (PhysOrg.com) -- Many hands -- or many flagella -- make light work. In studies of the motion of tiny swimming bacteria, scientists at the U.S. Department of Energy's Argonne National Laboratory found that the microscopic organisms can stir fluids remarkably quickly and effectively. As a result, the bacterial flagella could act like tiny motors to mix chemicals in biomedical kits, among other applications.
