Message: [QUOTE="MCC, post: 889911, member: 145"] Yes, very neat stuff. Gets even "neatier"when you consider bacterial swarming. The physics of motion - especially inertia / momentum and shear forces - are vastly different from what occurs on our "macro" level. Some of the "behavioral responses" are similar. The paper below might interest you. [URL='http://www.ncbi.nlm.nih.gov/pubmed/24329471#']Phys Rev Lett.[/URL] 2013 Nov 27;111(22):228101. Epub 2013 Nov 25.

[SIZE=4][B][URL='http://www.ncbi.nlm.nih.gov/pubmed/24329471#']Author information [/URL][/B] [B]Abstract[/B][/SIZE] We set up a macroscopic model of bacterial growth and transport based on a dynamic preferred direction-the collective velocity of the bacteria. This collective velocity is subject to the isotropic-nematic transition modeling the density-controlled transformation between immotile and motile bacterial states. The choice of the dynamic preferred direction introduces a distinctive coupling of orientational ordering and transport not encountered otherwise. The approach can also be applied to other systems spontaneously switching between individual (disordered) and collective (ordered) behavior and/or collectively responding to density variations, e.g., bird flocks, fish schools, etc. We observe a characteristic and robust stop-and-go behavior. The inclusion of chirality results in a complex pulsating dynamics. [/QUOTE]
