Special Seminar, Tues, June 18, 10:30 AM, PNI PSH 101, Isabel Beets, KU Leuven, "System-wide mapping of neuropeptide signaling networks in C. elegans"
Tue, Jun 18, 2024, 10:30 am11:30 am

Neuropeptides are ubiquitous signaling molecules that underpin almost all brain functions. They mediate extrasynaptic communication in nervous systems predominantly by binding to cell surface G protein-coupled receptors (GPCRs). The number of neuropeptide pathways is diverse and peptide-activated GPCRs are widely expressed throughout the brain,…

Biophysics Seminar: Maria de la Paz Fernandez | Barnard College Columbia | Sex Differences in the Drosophila Circadian System
Mon, May 13, 2024, 12:30 pm1:30 pm

Circadian clocks regulate the timing of various behavioral and physiological activities in most organisms on a 24-hr scale such that they are phased appropriately to external, cyclic changes in the environment. The clock neuronal network in Drosophila melanogaster is comprised of  ~150 neurons distributed bilaterally in the brain,…

Biophysics Seminar: Michael Hinczewski | Case Western Reserver University | The price of evolution: how thermodynamics shapes gene regulation
Mon, May 6, 2024, 12:30 pm1:30 pm

Many of the physical processes in a cell consume energy, but we are only beginning to understand how these costs have influenced the course of evolution. Biology is strewn with counter-intuitively complex mechanisms whose evolutionary predecessors must have consumed significant energy resources without any clear fitness benefit. So how do such…

Biophysics Seminar: Amy Shyer & Alan Rodrigues | Rockefeller University |Supracellular organization of morphogenesis: epigenetics beyond the cell
Mon, Apr 29, 2024, 12:30 pm1:30 pm

In recent decades, much progress has been made in understanding how genes within cells contribute to organ-specific fates or disease phenotypes. However, it is becoming more widely acknowledged that increasing understanding at the molecular scale has not been sufficient to fully grasp how tissues comprised of thousands of cells generate their…

Canceled. To be re-scheduled: Biophysics Seminar: Patrick Secor | University of Montana | Filamentous bacteriophages: Master manipulators of bacterial virulence potential
Mon, Apr 22, 2024, 12:30 pm1:30 pm

Pseudomonas aeruginosa is an opportunistic bacterial pathogen. Most P. aeruginosa isolates are infected by a filamentous virus (phage) called Pf. At sites of infection, filamentous Pf virions accumulate where they increase mucus viscosity, promote bacterial colonization, and directly stimulate innate anti-viral immune…

Biophysics Seminar: Allyson Sgro | Janelia Research Campus | Understanding the emergence of microbial collective behaviors
Mon, Apr 8, 2024, 12:30 pm1:30 pm

Groups of cells of all kinds work together as part of multicellular behaviors ranging from collective migration to development. These behaviors are coordinated at the level of single cells, where information about other cells and the environment are encoded in intracellular signaling dynamics that then drive cellular-level behaviors. We face…

Biophysics Seminar: Jonas Cremer | Stanford University | Causes and consequences of bacterial growth - from protein synthesis to the human gut microbiota
Mon, Apr 1, 2024, 12:30 pm1:30 pm

Growth is central to life, shaping physiology, ecology, and evolution. In this talk, I discuss our efforts to elucidate the causes and consequences of bacterial growth across scales. Starting from resource allocation models and the molecular and energetic demands of protein synthesis, I first introduce how bacterial cells adjust their…

Biophysics Seminar: Quan Wen | University of Science and Technology of China | Organizing Motor Behaviors Across Timescales
Tue, Mar 19, 2024, 12:30 pm1:30 pm

Animal behaviors are complex and hierarchical spatiotemporal patterns. In the popular model organism Caenorhabditis elegans, behavioral sequences on a slower timescale emerge from ordered and flexible transitions between different motor states, such as forward movement, reversal, and turn. On a faster timescale, intricate head…

Biophysics Seminar: Douglas Shepherd | Arizona State University |Exploring the 'rules of life' through optical microscopy
Mon, Feb 19, 2024, 12:30 pm1:30 pm

One governing principle of the microscopic world is "predictable randomness," where snapshots of a fluctuating process may appear random, but the average outcome of the process is predictable. An exciting frontier in biological physics is evaluating if predictable randomness extends to more complex, multi-component biophysical systems, such as…

Goal-reaching problems are ubiquitous in both the natural and engineered world. While learning to achieve goals is often considered an aspect of intelligence in biological systems, it is challenging to design practical algorithms for learning such behavior in high-dimensional environments. In this talk, I'll discuss recent work on contrastive…

Biophysics Seminar: Wolfgang Losert | University of Maryland College Park | Sensing Physical Signals with Cytoskeletal Dynamics
Mon, Feb 5, 2024, 12:30 pm1:30 pm

The dynamic assembly and disassembly of the cytoskeleton can create waves and oscillations that are critical to cell migration and other important cell behaviors.  Chemical signals have been found to trigger and steer these waves, facilitating the guidance e.g. of immune cells to their target.   Here we consider the role of these…

Biophysics Seminar: Daniel Goldman | Georgia Institute of Technology | Life at Low Coasting Number
Mon, Dec 11, 2023, 12:30 pm1:30 pm

In 1974 Purcell authored a paper “Life at Low Reynolds Number” to describe the counterintuitive world of microscopic organisms in which viscous dissipation so dominates inertia that “coasting” is impossible, and that the geometry of a path in an internal movement space dominates self-propulsion. It is typically assumed that a key difference…

Biophysics Seminar: Tatiana Engel | Princeton University | The dynamics and geometry of choice in premotor cortex
Mon, Nov 27, 2023, 12:30 pm1:30 pm

Neural responses in association brain areas during cognitive tasks are heterogeneous, and the widespread assumption is that this heterogeneity reflects complex dynamics involved in cognition. However, the complexity may arise from a fundamentally different coding principle: the collective dynamics of a neural population encode simple…

Mon, Nov 13, 2023, 12:30 pm1:30 pm

Deep in the ocean or underground, where there is no oxygen, Geobacter “breathe” by projecting tiny hair-like protein filaments called "nanowires" into the soil, to dispose of excess electrons resulting from the conversion of nutrients to energy, cleaning up radioactive sites. Although it is long known that Geobacter…

Mon, Nov 6, 2023, 12:30 pm1:30 pm

Recent advances in electrophysiology and optical imaging technologies enable recordings in behaving animals from hundreds or even thousands of neurons simultaneously. Since neural coding, computation, and communication rely on coordinated activity patterns across large cell populations, such data facilitate the study of the global structure of…

Biophysics Seminar: Jerelle Joseph | Princeton University | Accurate computer models for understanding and engineering biomolecular condensates
Mon, Oct 30, 2023, 12:30 pm1:30 pm

The interior of cells contains numerous components that need to be carefully organized in space to fulfill a wide range of biological functions. The most widespread form of intracellular compartments completely lack membranes. In the place of membranes, these compartments—so called biomolecular condensates—are sustained and segregated in space…

Earth’s atmosphere provides a thin barrier to the severe conditions of space. Globally, terrestrial microorganisms from our planet’s surface move through and interact with the blanketing atmosphere, analogous to how marine microbes drift through vast oceans. Whereas a century of exploration has allowed oceanographers to characterize…
