Motility coupled with responsive behavior is essential for microorganisms to establish suitable habitats, with simple responses like reversing motion enabling them to form stable aggregates. Kurjahn et al. show that filamentous cyanobacteria use light gradients and boundary curvature of light stimuli to form ordered, entangled aggregates, revealing how these dynamics could influence adaptive colony architectures.
