Betterton

Meredith Betterton presented the Biophysics Seminar at the Center for the Physics of Biological Function at Princeton.

Our paper "Analytical structure, dynamics, and coarse-graining of a kinetic model of an active fluid" was published by Physical Review Fluids.

Michael Stefferson's paper "Effects of soft interactions and bound mobility on diffusion in crowded environments: a model of sticky and slippery obstacles" was accepted for publication by Physical Biology.

There are many biological systems in which tracer particles diffuse in a crowded environment. We implemented a lattice Monte Carlo model to analyze the effects of binding kinetics, bound motion, and obstacle size on tracer diffusive in the presence of soft obstacles.

Meredith Betterton has been promoted to full professor of physics.

Our collaborative paper with Phong Tran's lab, "Kinesin-5-independent mitotic spindle assembly requires the antiparallel microtubule crosslinker Ase1 in fission yeast," was published by Nature Communications .

Pushing forces generated by microtubule polymerization are sufficient to promote spindle pole separation and the assembly of bipolar spindle in the absence of molecular motors.

Our paper "Analytical structure, dynamics, and coarse-graining of a kinetic model of an active fluid" was posted on the arXiv preprint server today.

One of the simplest active suspensions with complex dynamics is a suspension of immotile "Extensor" particles that exert active extensile dipolar stresses on the fluid in which they are immersed.

Our paper "Contributions of microtubule dynamic instability and rotational diffusion to kinetochore capture" was published in final form today by the Biophysical Journal and highlighted on the Biophysical Journal website.
