Abstract
Biological systems use sensors and memory devices to adaptively anticipate external changes, in order to optimize their energy costs. This is done by dynamically changing accessibility to information sources, namely to gene code, by photoexcitable chromatin remodelling and softly inherited epigenetic changes. In particular, metabolic events such as timing of cellular differentiation and division are modulated by (quasi)periodic variations in ambient electromagnetic spectra, eventually leading to boundary formation in a structuring population. We analyze a DDE model of a key gene expression control loop, a smartly adaptive intracellular memory device.
