The organized movement of intracellular material is part of the functioning of cells and the development of organisms. These flows can arise from the action of molecular machines on the flexible, and often transitory, scaffoldings of the cell. That sounds complex and multiscaled, as is much of biology, but its study is also becoming a beautiful sub-branch of biophysical fluid dynamics characterized by geometric complexity, confinement, and microscale activity. Understanding phenomena in this realm has necessitated the development of new simulation tools, and of new coarse-grain mathematical models to analyze and simulate. I'll discuss intracellular flows as signatures of force transduction, a newly discovered symmetry-breaking "swirling" instability of a motor-laden cytoskeleton of an oocyte, and what models of active, immersed polymers might tell us about chromatin dynamics in the nucleus.
