Stable pressure gradients can arise in cells from the combination of actomyosin-generated cortical tension, cytoplasmic poroelasticity, and water flows across the membrane.
Fluid flow analysis reveals that both swimming and sessile ciliates achieve competitive nutrient uptake, resolving the long-standing debate over the hydrodynamic advantage of either strategy.
Combining statistical modeling with flow cytometry enables reliable, high-throughput quantification of division asymmetry in live cells, revealing how partitioning noise may shape tumor cell heterogeneity.
