High-resolution GPS data revealed a quadratic relationship between group size and movement, with vulturine guineafowl groups of intermediate size exhibiting the largest home-range size and greater variation in site use.
A computational model of collective physical interaction reveals that individuals infer the collective's movement goal in order to enhance the group's overall performance and coordinate with several partners in seconds.
Rab25a and Rab25b mutant embryos exhibit epithelial spreading delays during morphogenesis and are characterized by cytokinesis defects leading to cell fusions, heterogeneous epithelial cell sizes, and reduced cortical actomyosin contractility.
Protein phosphatase 1 activity promotes cohesive collective cell migration by restricting actomyosin contractility to the periphery of the collective and maintaining proper cadherin–catenin complex protein levels at cell–cell junctions.
The super-resolution fluorescence microscopy approach polarization PALM (p-PALM) reveals that macromolecular crowding and inhomogeneity within nuclear pores generate a structurally and dynamically complex permeability barrier.
