SUMMARY:Marvels of bacterial behavior
DESCRIPTION:Featuring Howard Berg\, Harvard University\nHosted by: Sidney R
	edner\nPoster: http://physics.bu.edu/posters/2010_Fall/03_Berg.pdf\n\nPart 
	of the Physics Department Colloquia Series.\n\nAbstract:\n\nEscherichia col
	i swims by rotating long\, thin\, helical filaments that arise at different
	 points on the cell surface.  Each filament is driven at its base by a rota
	ry motor only 45 nm in diameter made from about 20 different kinds of parts
	.  Cells are able to swim up gradients of chemical attractants by controlli
	ng the direction of rotation of these motors\, a process known as chemotaxi
	s.  I will touch upon the history of this subject\, tell you about some of 
	the physics that E. coli knows\, and describe some recent experiments relat
	ed to the signaling pathway\, the operation of the flagellar motor\, and th
	e social behavior observed when cells flock.
