Bacterium makes complicated loops

The magnetotactic bacterium Magnetococcus marinus swims with the help of two bundles of flagella, which are thread-like structures. This bacterium possesses a sort of intracellular ‘compass needle’ and their movements can be controlled using a magnetic field. So they can be used as a biological model for microrobots. An international team has investigated how these bacteria move and determined their swimming speed. https://www.sciencedaily.com/releases/2020/02/200227114509.htm
