    Investigating molecular crowding within nuclear pores using polarization-PALM

    Guo Fu et al.
    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.

    Cellular interpretation of the long-range gradient of Four-jointed activity in the Drosophila wing

    Rosalind Hale et al.
    Opposing gradients of Fat and Dachsous phosphorylation are sufficient to explain the observed pattern of Fat-Dachsous planar polarisation across the Drosophila wing.

    Reciprocal and dynamic polarization of planar cell polarity core components and myosin

    Erin Newman-Smith et al.
    Planar cell polarity (PCP) components and myosin show a parallel temporal polarization in the Ciona notochord and the mutual interaction between these proteins is required for proper tissue-wide polarity.

    Symmetry breaking in reconstituted actin cortices

    Enas Abu Shah, Kinneret Keren
    A reconstituted system has been developed that self-organizes into dynamic actin cortices capable of spontaneous polarization, similar to the initial cortical polarization observed in cells during embryogenesis and development.

    A visual pathway for skylight polarization processing in Drosophila

    Ben J Hardcastle et al.
    Circuit tracing and in vivo calcium imaging reveals neurons conveying polarized light information from photoreceptors to the central brain, transforming patterns in the sky into a directional cue for navigation.

    Evolutionary adaptation after crippling cell polarization follows reproducible trajectories

    Liedewij Laan et al.
    Deletion of one gene can lead to inactivation of other genes which restore a perturbed cellular function but change the epistatic interactions and the dynamics of the responsible module.

    Revealing architectural order with quantitative label-free imaging and deep learning

    Syuan-Ming Guo et al.
    Advances in quantitative phase and polarized light microscopy, combined with deep learning, reveal the architecture of human brain tissue.

    Kinesin-4 KIF21B limits microtubule growth to allow rapid centrosome polarization in T cells

    Peter Jan Hooikaas et al.
    Kinesin-4 KIF21B promotes rapid reorientation of the microtubule network during formation of immunological synapse in T cells by acting as a pausing and catastrophe-inducing factor that keeps microtubules short.

    TRPV4 is the temperature-sensitive ion channel of human sperm

    Nadine Mundt et al.
    The molecular identity of the temperature-sensitive ion channel of human sperm that ensures depolarization is TRPV4.
