News article at Physics World about work on biofilm streamers: link.


Video of flow generated by a single swimming bacterium (E. coli). The flow field is so small that its effects are mostly drowned by diffusion.





How do multicellular organisms without a central nervous system of communication between the individual cells coordinate organism-level behaviors? This video, based on a mathematical model, shows that the spherical alga Volvox carteri can turn towards the light by endowing each cell on its surface with a common, fine-tuned response to light. The response magnitude is color-coded.





Video of dancing microorganisms: These bound states are due to hydrodynamic interactions between swimming Volvox carteri.
