Pictured are two biomolecular networks from budding yeast, composed of different basic architectures. The generalized time-frequency analysis framework developed by Ratushny et al. enables the systematic exploration of the dynamical properties of biomolecular networks. Using this framework, the authors reveal remarkably distinct network behaviors in terms of trade-offs between responsiveness and noise suppression that are appropriately tuned to each biological response.
