Helical Bacteria Swim in Visco-elastic Fluid

January 11, 2013
A type of bacteria called helical bacteria swim in dense, sticky fluids like mucus (visco-elastic fluid). To learn more about this National Science Foundation-supported research by engineers at Brown University, see the story "Force-free swimming of a model helical flagellum in viscoelastic fluids" in the online.
