Abstract: The cellular communications that regulates cell fate must be precisely controlled to avoid dangerous errors. How is this achieved? Recent work has highlighted the importance of positive and negative feedback networks in the dynamic regulation of signalling. These feedback interactions can impart precision, robustness, noise rejection and versatility to cellular signals. They can also produce interesting emergent dynamical properties like biological switches and chemical oscillators, whose properties and purpose must be explained.
