Prof. David R. Nelson (Harvard University and Niels Bohr Institute)25/05/2013, 09:00Recent experiments have revealed a remarkable growth mechanism for rod-shaped bacteria: specialized proteins associated with cell wall elongation move at constant velocity in clockwise and counterclockwise directions on circles around the cell circumference. We argue that this machinery attaches to dislocations in the ordered peptidoglycan cell wall, and study theoretically...Go to contribution page

Prof. Thierry Mora (ENS)25/05/2013, 09:45The maintenance of cooperation in populations where public goods are equally accessible to all, but inflict a fitness cost on its sole producers, is a long-standing puzzle of evolutionary biology. An example of such a scenario is the secretion of siderophores by bacteria into their environment in order to fetch soluble iron. In a well-mixed culture, these molecules diffuse rapidly, such...Go to contribution page

Prof. Sergei Maslov (Brookhaven National Laboratory)25/05/2013, 10:45Understanding evolutionary dynamics of bacterial genomes is of great importance in microbiology, microbial ecology, and epidemiology. Collective effects play an important role in shaping this dynamics due to ubiquitous horizontal gene transfer between different members of bacterial population. We recently interpreted the variability of 37 fully sequenced genomes of E. coli and Shigella...Go to contribution page
