    Cortical microtubule nucleation can organise the cytoskeleton of Drosophila oocytes to define the anteroposterior axis

    Philipp Khuc Trong, Hélène Doerflinger ... Raymond E Goldstein
    A three-dimensional description of the cytoskeletal arrangement, cytoplasmic flows, and cargo transport in stage 9 Drosophila oocytes accurately reproduces mRNA localizations in wild-type and mutant oocytes.

    Interplay of cell dynamics and epithelial tension during morphogenesis of the Drosophila pupal wing

    Raphaël Etournay, Marko Popović ... Suzanne Eaton
    Autonomous patterns of cell contraction in the context of localized apical extracellular matrix constraints specify tissue stresses that reshape the wing epithelium.

    Phenotypic states become increasingly sensitive to perturbations near a bifurcation in a synthetic gene network

    Kevin Axelrod, Alvaro Sanchez, Jeff Gore
    Perturbations in the extracellular environment drive transitions from a highly stable memory state to an alternative phenotype in microorganisms.

    Side-binding proteins modulate actin filament dynamics

    Alvaro H Crevenna, Marcelino Arciniega ... Don C Lamb
    The kinetics of actin polymerization are strongly influenced by the binding of proteins to the lateral filament surface.

    Distinct mechanisms regulating mechanical force-induced Ca2+ signals at the plasma membrane and the ER in human MSCs

    Tae-Jin Kim, Chirlmin Joo ... Yingxiao Wang
    Deep penetration and transmission of mechanical force to regulate ER functions depends on not only the passive cytoskeletal support, but also the active actomyosin contractility, which is dispensable for mechanotransduction at the plasma membrane.

    Mechanical design principles of a mitotic spindle

    Jonathan J Ward, Hélio Roque ... François Nédélec
    Precise control of microtubule architecture greatly increases the force that the spindle can exert on chromosomes.

    Active torque generation by the actomyosin cell cortex drives left–right symmetry breaking

    Sundar Ram Naganathan, Sebastian Fürthauer ... Stephan W Grill
    The actomyosin cytoskeleton generates active chiral torques that lead to left-right asymmetry in C. elegans embryos.

    Phase transitions of multivalent proteins can promote clustering of membrane receptors

    Sudeep Banjade, Michael K Rosen
    A new and general mechanism describes the organization of membrane proteins and their cytoplasmic ligands into micrometer-scale clusters, based on polymerization and concomitant phase separation of multivalent proteins.

    Predicting evolution from the shape of genealogical trees

    Richard A Neher, Colin A Russell, Boris I Shraiman
    A general method for inferring fitness from a sample of nucleotide sequences can predict the progenitor of next year's seasonal influenza.
