I went to the annual Harvard Microbial Sciences Initiative symposium today for the forth year in a row. There are always some great talks at this event.
Harvard MSI is very much centered around microbial communities and social microbiology. There were many great speakers but I was particularly interested in a talk about about swarming in Proteus mirabilis.
Proteus mirabilis is able to self-recognize cells of the same species using surface-bound proteins and differentiates into hyper-motile large swarming cells able to glide over solid surfaces.
