Single cells and noise


 

When molecule numbers get sparse and events rare, underlying assumptions of ODE approaches falter and break down. In this regime, noise plays a fundamental role since it is in the same order of magnitude as the observables. Does noise in these cases exert a biological function? How do living systems filter, or cope with noise? Can we identify the input upstream of a signaling cascade given its output? We investigate questions like these from different perspectives ranging from specific biological systems to general theoretical concepts of information transmission.
