By using a specialized camera that corrects for eye blur, millions of single-blood-cells are imaged, and their speed measured, as they travel through the largest-to-smallest vessels of the retina.
By distributing receptor-binding and receptor-destroying proteins asymmetrically on their surface, filamentous influenza A virus particles create a Brownian ratchet that facilitates their passage through mucus.
A theoretical basis for the spatial regulation of protein aggregation shows how aggregates can partition preferentially into intracellular liquid compartments.
Environmental heterogeneity can dramatically reduce the efficacy of selection and alter the neutral evolutionary dynamics in microbial range expansions.
A multiphase hydrodynamic theory reveals that the dynamics of colony expansion in microbial swarms and biofilms are limited by the constraints of water and nutrient availability.
The expansion of bacterial swarms and the spreading of biofilms can be described by a unified biophysical theory that involves both active and passive processes.

A multi-phase wrinkling model accounts for the radial and circumferential tension and differential expansion between a uniformly proliferating outer fluid-like layer and an incompressible core that together drive cerebellar folding.
