SUMMARY:Flows and instabilities in cellular biomechanics
LOCATION:Zoom
DESCRIPTION:<p style="text-align: center;">Flows in the fluidic interior of living cell
 s can serve function, and by their structure shed light on how forces are e
 xerted within the cell. Some of these flows can arise through novel collect
 ive instabilities of the cytoskeleton, the set of polymers, cross-linkers, 
 and molecular motors that underlie much of the mechanics within and between
  cells. I'll discuss experiments, mathematical modeling and analysis, and s
 imulations of two such cases. One is understanding the emergence of <br /> 
 cell-spanning vortical flows in developing egg cells and driven by cargo-be
 aring molecular motors, while the other arises from studying the nature of 
 force transduction in the dynamics of microtubule arrays inside of syntheti
 c cells. Both show the importance of polymer density in determining dynamic
 s and time-scales, and have required the development of new coarse-grained 
 models and simulation methods.</p>
