To establish and maintain their internal organization, living cells must move molecules to their correct locations. Long-range intracellular movements are often driven by motor molecules moving along microtubules, similarly to trucks driving along a highway. Recent work demonstrates that some randomly dispersed cargos can generate actin filaments that form a connected network whose contraction drives collective cargo movement.
