Networks of actin filaments can provide force within a cell to generate movement, but the mechanism of how this occurs isn’t completely understood. A group recently created a computer model to simulate and predict motility caused by actin polymerization, and tested new predictions experimentally. The figure above shows how an actin network uniformly coating a bead will break its symmetry to result in movement of the bead (top). The computer simulation (middle) and a 3D view of the simulation (bottom) are also shown.
