Biophysics Seminar: Andrej Kosmrlj| Princeton University: Pattern formation in biological systems via mechanical instabilities and phase separation

Mon, Sep 20, 2021, 12:15 pm

Pattern formation is ubiquitous in biological systems. While pattern formations are often associated with Turing-like reaction-diffusion systems, biology also exploits many other mechanisms such as mechanical instabilities and phase separation.

Biophysics Seminar: Justin Kinney, Cold Spring Harbor Laboratory| Massively parallel assays, machine learning, and the biophysics of gene regulation| Zoom

Mon, May 10, 2021, 12:15 pm

Gene expression in all organisms is controlled by short DNA and RNA sequences called cis-regulatory elements (CREs). Proteins in the cellular milieu bind to nucleic acid sequences present within CREs, interact with one another, and thus form macromolecular complexes that modulate the expression of nearby genes.

Biophysics Seminar: Rosalind Allen, Edinburgh University| Geometry of bacterial growth and division| Zoom

Mon, May 3, 2021, 12:15 pm

The rod-shaped bacterium Escherichia coli proliferates by a process of elongation, followed by constriction at its centre to create new cell poles. Despite intense study, some apparently simple questions about the dynamics of growth and division in E.

Biophysics Seminar: Julia M. Yeomans, University of Oxford| Active nematic physics in cell layers and tissues| Zoom

Mon, Apr 26, 2021, 12:15 pm

Active materials such as bacteria, molecular motors and eukaryotic cells continuously transform chemical energy taken from their surroundings to mechanical work.

Biophysics Seminar: Susanne Still, University of Hawaii at Mānoa| Thermodynamics of information processing| Zoom

Mon, Apr 19, 2021, 4:00 pm

Living systems need to remember information about their environment in order to take decisions that ultimately ensure survival. But storing information about past experiences costs energy, while only a fraction of the vast amount of information available can be useful to the living system.

Biophysics Seminar: Nikta Fakhri, MIT |Broken symmetries in living matter | Zoom

Mon, Apr 12, 2021, 12:00 pm

Active processes in living systems create a novel class of non-equilibrium material composed of many interacting parts that individually consume energy and collectively generate motion or mechanical stress.

Biophysics Seminar: Satu Palva, University of Helsinki and University of Glasgow| Multi-scale synchronization dynamics in human cognition| Zoom

Mon, Mar 29, 2021, 12:15 pm

Perception, attention and working memory are fundamental cognitive functions, which are based on parallel processing in many brain areas. Neuronal oscillations at sub-second timescales and their phase correlations a.k.a.

Biophysics Seminar: Raymond E. Goldstein, University of Cambridge| Fluid and Light: Dinoflagellate Bioluminescence at the Single Cell Level| Zoom

Mon, Mar 22, 2021, 12:15 pm

One of the characteristic features of many marine dinoflagellates is their bioluminescence, which lights up nighttime breaking waves or seawater sliced
by a ship’s prow. While the internal biochemistry of light production by these microorganisms is well established, the manner by which fluid shear or mechanical

Biophysics Seminar: Kinneret Keren, Technion, Israel| Topological defects in the nematic order of actin fibers as organization centers of Hydra morphogenesis| Zoom

Mon, Mar 1, 2021, 12:15 pm

Morphogenesis, the emergence of functional form in a developing organism, is one of the most remarkable examples of pattern formation in nature. Despite substantial progress, we still do not understand the organizational principles underlying the convergence of this process, across scales, to form viable organisms under variable conditions.

Biophysics Seminar: Karen Alim, Technische Universität München| Network morphology to store memories| Zoom

Mon, Feb 22, 2021, 12:15 pm

Simple organisms manage to thrive in complex environments. Remembering information about the environment is key to take decisions. Physarum polycephalum excels as a giant unicellular eukaryote being even able to solve optimisation problems despite the lack of a nervous system.

Biophysics Seminar: Stephanie Palmer, University of Chicago| How behavioral and evolutionary constraints sculpt early visual processing| Zoom

Mon, Feb 1, 2021, 12:15 pm

An animal eye is only as efficient as the organism’s behavioral constraints demand it to be. Efficient coding has been a successful organizational principle in vision, and to make a more general theory, behavioral, mechanistic, and even evolutionary constraints need to be added to this framework.

Biophysics Seminar: Kranthi Kiran Mandadapu, University of California Berkeley: On the role of motility and glassy dynamics in growth of bacterial monolayers into the third dimension| Zoom

Mon, Nov 23, 2020, 12:15 pm

Many mature bacterial colonies and biofilms are complex three-dimensional (3D) structures. A key step in their developmental program is a transition from a two-dimensional (2D) monolayer into a 3D architecture.

Biophysics Seminar: Seppe Kuehn, University of Chicago| A sparse mapping from structure to function in microbial communities|Zoom

Mon, Nov 16, 2020, 12:15 pm

The metabolic function of microbial communities emerges through a complex hierarchy of genome-encoded processes, from gene expression to interactions between diverse taxa. Therefore, a central challenge for microbial ecology is deciphering how genomic structure determines metabolic function in communities.

Biophysics Seminar: Allan Drummond, University of Chicago: Rethinking the cellular response to heat shock, from biophysics to physiology| Zoom

Mon, Oct 26, 2020, 12:15 pm

Cells across the tree of life respond to a sudden, nonlethal rise in temperature--heat shock--in similar ways. Following heat shock, proteins and mRNAs form clumps, certain genes turn on, and protein synthesis and cell growth sharply decline.

Biophysics Seminar: Stefano Allesina, University of Chicago: Predicting coexistence in experimental ecological communities| Zoom

Mon, Oct 19, 2020, 12:15 pm

When experimenting with a large pool of species, a common problem is to determine a priori whether a certain subset of species can coexist when co-cultured. We propose a simple statistical model in which a number of species assemblages are observed, and the coexistence of novel assemblages is predicted out-of-fit.

Biophysics Seminar: Gurol Suel, University of California San Diego| The role of inorganic ions in bacterial resilience

Mon, Sep 28, 2020, 12:15 pm

We have been working to measure and understand how ion fluxes and ionic interactions regulate fundamental biological processes, and in particular promote stress tolerance in bacteria. I will present our recent work that builds on our discovery of action potentials generated within bacterial biofilms.
