First, we study the stability of a generic negative feedback loop with a delay, which is known to be prone to instabilities and oscillations. The negative feedback loop can describe equally genetic oscillators and nonlinear feedback regulation of cell population numbers. Understanding what affects stability (or instability) is thus relevant for the two biological scales (intracellular and cell population) of interest here. Then, we show how interaction (cell-cell communication though a diffusible factor) can transform a collection of sloppy oscillators into a robust, noise-resistant clock. There is evidence that the clock neurons follow this design principle. We then look at the long-term renewal capacity of tissues in human. We discuss how...
