lessTitle: Mathematics of Life Seminar Series: Randomness, Complexity, and the Biological Frontier
Speaker: Pankaj Mehta, Boston University
Abstract: The towering successes of twentieth century theoretical physics were marked by two guiding principles: symmetry and energy functionals (reflecting equilibrium dynamics). Yet how we can exploit these principles to develop a theory of living systems is unclear since the biological world is composed of heterogeneous, interacting components operating out of equilibrium. In this talk, I will argue that one possible strategy for taming biological complexity is to embrace the idea that many biological behaviors we observe are “typical” and can be modeled using random systems that respect biologically-inspired constraints. I will focus on showing how this approach can be used to make close connection with experiments by presenting three vignettes focusing on: (i) theory-inspired techniques for visualizing single-cell transcriptomics data for cellular identity, (ii) understanding how the interplay between cross-feeding and competition shapes microbial ecosystems and (iii) the emergence of chaos in the ecosystems with non-reciprocal interaction.

lessThe Center for Scientific Studies in the Arts is a collaboration between the Art Institute of Chicago and materials science-related departments at Northwestern University to pursue objects-based and objects-inspired scientific research. Materials research benefits ongoing work in conservation, archaeology, art history, and curatorial scholarship.
Learn how the Center uses materials research to care for art objects in sustainable, innovative ways with Maria Kokkori, Senior Scientist in the Center for Scientific Studies in the Arts. She will be in conversation with Corey Byrnes, Northwestern Associate Professor of Chinese Culture and co-founder/co-director of the Environmental Humanities Workshop in Kaplan Humanities Center.
This event is presented by the McCormick School of Engineering and Applied Science in conjunction with exhibition Actions for the Earth: Art, Care & Ecology.

lessTitle: Active Fractal Networks with Stochastic Force Monopoles and Force Dipoles Unravel Subdiffusion of Chromosomal Loci
Speaker: Rony Granek, Ben Gurion University of the Negev
Abstract: Motivated by the well-known fractal packing of chromatin, we study the Rouse-type dynamics of elastic fractal networks with embedded, stochastically driven, active force monopoles and force dipoles that are temporally correlated. We compute, analytically – using a general theoretical framework – and via Langevin dynamics simulations, the mean square displacement (MSD) of a network bead. Following a short time superdiffusive behavior, force monopoles yield anomalous subdiffusion with an exponent identical to that of the thermal system. In contrast, force dipoles do not induce subdiffusion, and the early superdiffusive MSD crosses over to a relatively small, system-size-independent saturation value. In addition, we find that force dipoles may lead to ``crawling" rotational motion of the whole network, reminiscent of that found for triangular micro-swimmers and consistent with general theories of the rotation of deformable bodies. Moreover, force dipoles lead to network collapse beyond a critical force strength, which persists with increasing system size, signifying a true first-order dynamical phase transition. We apply our results to the motion of chromosomal loci in bacteria and yeast cells' chromatin, where anomalous sub-diffusion, MSD∼ t^ν with ν≃ 0.4, were found in both normal and ATP-depleted cells, albeit with different apparent diffusion coefficients. We show that the combination of thermal, monopolar, and dipolar forces in chromatin is typically dominated by the active monopolar and thermal forces, explaining the observed normal cells vs the ATP-depleted cells behavior.
