I am very happy to announce that our paper on how bacteria use type IV pili to move over a substrate is published in PRE!
We find that a tug-of-war mechanism alone is able to explain the persistent motion of bacteria without including any directional memory. In our work, we also predict that substrate friction might play a major role during the motility of cell aggregates.

This project has been one of my favorites in the last three years and I hope people will enjoy reading it.
