EMS Lecture: Cytoplasmic Streaming and the Swirling Instability of the Microtubule Cytoskeleton

Prof. Raymond Goldstein (University of Cambridge)

Friday 9th December, 2022 16:30-17:30 Room 116 of Maths & Stats Building


The Edinburgh Mathematical Society will be hosting a talk locally at the University of Glasgow this Friday, 9 December from 4:30pm. The talk will be in hybrid style: the speaker will be giving his talk in person in Glasgow and the talk will be live streamed at the same time via Zoom.

The speaker is Professor Raymond Goldstein FRS of University of Cambridge. Prof. Goldstein's research focuses on understanding nonequilibrium phenomena in the natural world, with particular emphasis on biological physics. Prof. Goldstein is the recipient of many honours and awards, including the Rosalind Franklin Medal and Prize, Institute of Physics (2016), the Schlumberger Chair for Mathematical Sciences, Institut des Hautes Études Scientifiques, Bures-sur-Yvette, France (2017), and an ERC Advanced Investigator Grant.

Title: Cytoplasmic Streaming and the Swirling Instability of the Microtubule Cytoskeleton
Abstract: Cytoplasmic streaming is the persistent circulation of the fluid contents of large eukaryotic cells, driven by the action of molecular motors moving along cytoskeletal filaments, entraining fluid. Discovered in 1774 by Bonaventura Corti, it is now recognized as a common phenomenon in a very broad range of model organisms, from plants to flies and worms. This talk will discuss physical approaches to understanding this phenomenon through a combination of experiments (on aquatic plants, Drosophila, and other active matter systems), theory, and computation.  A particular focus will be on streaming in the Drosophila oocyte, for which I will describe a recently discovered “swirling instability” of the microtubule cytoskeleton.
