Absolutely delighted that Iago’s paper on the transition from bacterial swarming to biofilms is now out on eLife.
When the expansion of a B. subtilis swarm is hindered (even just by a simple barrier!) cells at the front pile up through a physical process similar to a traffic jam (a transient one in the movie!). This in turn leads to the emergence of a localised biofilm. This is the first direct report we could find of a transition between swarming and biofilm! Great work by Iago and fab collaboration with Munehiro Asally!
Ah! …here’s eLife‘s press release!
