Collective dynamics of trail-interacting particles
Paul Pineau, Samuel Bell, Raphaël Voituriez +1
Trail interactions occur when past particle trajectories bias future motion, rendering the system out of thermodynamic equilibrium. While such systems are abundant in nature, their…
Active flow-driven DNA remodeling generates millimeter-scale mechanical oscillations
Maya Levanon, Noa S. Goldberg, Dvir Cohen +3
In living systems, DNA undergoes continuous and rhythmic mechanical remodeling through condensation, looping, and disentangling to regulate gene expression, segregate chromosomes,…
Theory of cell size regulation during migration in adhered cells
Jonathan E. Ron, Ram M. Adar
Cell migration is closely linked to cell shape, yet cell size is often assumed to remain constant. This assumption is challenged by recent experiments showing that cells undergo vo…
Separation of ionic timescales explains dynamics of cellular volume regulation
Ram M. Adar
Living cells actively regulate their volume in response to changes in the extra-cellular environment, such as osmolarity and chemo-attractant concentration. While the basic physica…
