SUMMARY:Martin Nowak\, Evolution of cooperation
DESCRIPTION:Abstract: Cooperation means that one individual pays a cost for another to receive a benefit. Cooperation can be at variance with natural selection. Why should you help competitors? Yet cooperation is abundant in nature and is important component of evolutionary innovation. Cooperation can be seen as the master architect of evolution and as the third fundamental principle of evolution beside mutation and selection. I will present five mechanisms for the evolution of cooperation: direct reciprocity\, indirect reciprocity\, spatial selection\, group selection and kin selection. Global cooperation and the cooperation with future generations is necessary to ensure the survival of our species. \nFurther reading:\nNowak MA (2006). Evolutionary Dynamics.

SUMMARY:Eui Min Jung\, Antithetic Integral Feedback Ensures Robust Perfect Adaptation in Noisy Biomolecular Networks
DESCRIPTION:We will discuss about “Antithetic Integral Feedback Ensures Robust Perfect Adaptation in Noisy Biomolecular Networks”\, Briat\, Corentin\, Ankit Gupta\, and Mustafa Khammash. Cell systems 2.1 (2016): 15-26. \nAbstract \n\nThe ability to adapt to stimuli is a defining feature of many biological systems and critical to maintaining homeostasis. While it is well appreciated that negative feedback can be used to achieve homeostasis when networks behave deterministically\, the effect of noise on their regulatory function is not understood. Here\, we combine probability and control theory to develop a theory of biological regulation that explicitly takes into account the noisy nature of biochemical reactions. We introduce tools for the analysis and design of robust homeostatic circuits and propose a new regulation motif\, which we call antithetic integral feedback. This motif exploits stochastic noise\, allowing it to achieve precise regulation in scenarios where similar deterministic regulation fails. Specifically\, antithetic integral feedback preserves the stability of the overall network\, steers the population of any regulated species to a desired set point\, and adapts perfectly. We suggest that this motif may be prevalent in endogenous biological circuits and useful when creating synthetic circuits.
