    Physical limits of flow sensing in the left-right organizer

    Rita R Ferreira et al.
    Large-scale in vivo imaging of the zebrafish left-right organizer (Kupffer's vesicle) combined with fluid dynamics calculations allows to quantitatively test the possible flow detection mechanisms and supports the flow transport of chemical signals as the mechanism of side determination.

    A physical model describing the interaction of nuclear transport receptors with FG nucleoporin domain assemblies

    Raphael Zahn et al.
    A homopolymer-sphere model is shown to accurately reproduce the interactions that underpin selective gating of macromolecular transport into and out of the cell nucleus.

    Physical basis of large microtubule aster growth

    Keisuke Ishihara et al.
    Autocatalytic growth of a microtubule polymer network allows extremely large egg cells to self-organize and divide rapidly.

    Microtubule plus-ends act as physical signaling hubs to activate RhoA during cytokinesis

    Vikash Verma, Thomas J Maresca
    MT plus-end-mediated recruitment of a cortical pool of ECT2 trigger RhoA activation upon contact, which results in localized contractility during cytokinesis.

    Physical determinants of vesicle mobility and supply at a central synapse

    Jason Seth Rothman et al.
    Hydrodynamic and steric interactions slow vesicle mobility and are predicted to ultimately limit vesicle supply to the active zone during sustained high-frequency signalling at a central synapse.

    The physical dimensions of amyloid aggregates control their infective potential as prion particles

    Ricardo Marchante et al.
    Size threshold and suprastructure formation are key parameters that control the infective potential of amyloid fibrils as prion particles.

    Phasic activation of ventral tegmental neurons increases response and pattern similarity in prefrontal cortex neurons

    Motoko Iwashita
    Transient increases in calcium release in prefrontal cortex neurons, observable only in awake animals, may form the basis of associative learning.

    The genetic landscape of a physical interaction

    Guillaume Diss, Ben Lehner
    First comprehensive analysis of how many different mutations combine within and between two genes to alter a molecular phenotype.

    Point of View: Are theoretical results ‘Results’?

    Raymond E Goldstein
    There should be a prominent place for theory within biology papers, both as Results in papers that combine experiment and theory, and as Results in theory papers.
