The Actin Cytoskeleton as an Active Adaptive Material.

Annu Rev Condens Matter Phys 2020 Mar 6;11(1):421-439. Epub 2019 Dec 6.

Institute for Theoretical Physics and BioQuant, Heidelberg University, 69120 Heidelberg, Germany.

Actin is the main protein used by biological cells to adapt their structure and mechanics to their needs. Cellular adaptation is made possible by molecular processes that strongly depend on mechanics. The actin cytoskeleton is also an active material that continuously consumes energy. Read More

Antagonistic Phenomena in Network Dynamics.

Annu Rev Condens Matter Phys 2018 Mar;9:463-484

Chair of Network Dynamics, Institute for Theoretical Physics and Center for Advancing Electronics (cfaed), Technical University of Dresden, 01062 Dresden, Germany.

Recent research on the network modeling of complex systems has led to a convenient representation of numerous natural, social, and engineered systems that are now recognized as networks of interacting parts. Such systems can exhibit a wealth of phenomena that not only cannot be anticipated from merely examining their parts, as per the textbook definition of complexity, but also challenge intuition even when considered in the context of what is now known in network science. Here we review the recent literature on two major classes of such phenomena that have far-reaching implications: (i) antagonistic responses to changes of states or parameters and (ii) coexistence of seemingly incongruous behaviors or properties-both deriving from the collective and inherently decentralized nature of the dynamics.

Adaptation of Living Systems.

Annu Rev Condens Matter Phys 2018 Mar 8;9:183-205. Epub 2017 Dec 8.

Department of Physics, UCSD, La Jolla, CA 92093.

Adaptation refers to the biological phenomenon where living systems change their internal states in response to changes in their environments in order to maintain certain key functions critical for their survival and fitness. Adaptation is one of the most ubiquitous and arguably one of the most fundamental properties of living systems. It occurs throughout all biological scales, from adaptation of populations of species over evolutionary time to adaptation of a single cell to different environmental stresses during its life span.

Annu Rev Condens Matter Phys 2015 Mar;6:85-111

Department of Applied Physics and Division of Biology, California Institute of Technology, Pasadena, California 91125; Laboratoire de Physico-Chimie Théorique, CNRS/UMR 7083-ESPCI, 75231 Paris Cedex 05, France.

It has been said that the cell is the test tube of the twenty-first century. If so, the theoretical tools needed to quantitatively and predictively describe what goes on in such test tubes lag sorely behind the stunning experimental advances in biology seen in the decades since the molecular biology revolution began. Perhaps surprisingly, one of the theoretical tools that has been used with great success on problems ranging from how cells communicate with their environment and each other to the nature of the organization of proteins and lipids within the cell membrane is statistical mechanics.
