    A lipid bound actin meshwork organizes liquid phase separation in model membranes

    Alf Honigmann et al.
    A combination of imaging experiments and computer simulations on a model lipid membrane integrate the 'picket fence' and 'raft' models, and suggest that the interplay between actin binding, lipid phase separation and curvature compartmentalize the membrane.

    Genetic defects in β-spectrin and tau sensitize C. elegans axons to movement-induced damage via torque-tension coupling

    Michael Krieg et al.
    A conceptual framework and physical model shows how actin-spectrin networks and microtubule bundles can protect axons from mechanical stress.

    3D visualization of mitochondrial solid-phase calcium stores in whole cells

    Sharon Grayer Wolf et al.
    Mammalian mitochondria in living cells store calcium phosphate in solid form.

    Cellular aspect ratio and cell division mechanics underlie the patterning of cell progeny in diverse mammalian epithelia

    Kara L McKinley et al.
    The process of cytokinesis can allow cell lineages to intermix in mammalian epithelia, and cellular aspect ratio is a critical modulator of this behavior.

    Two-step membrane binding by the bacterial SRP receptor enable efficient and accurate Co-translational protein targeting

    Yu-Hsien Hwang Fu et al.
    Single molecule microscopy combined with biochemical analyses show that a two-step lipid-binding mechanism of the SRP receptor balances the trade-off between speed and specificity during co-translational protein targeting.

    Chronic 2P-STED imaging reveals high turnover of dendritic spines in the hippocampus in vivo

    Thomas Pfeiffer et al.
    Super-resolution STED microscopy is demonstrated for the first time in the deeply embedded mouse hippocampus in vivo, revealing direct evidence for an unprecedentedly high level of synapse remodeling in a brain structure closely associated with memory processing.

    Malaria: Age, exposure and immunity

    Michael White, James Watson
    The acquisition of immunity to malaria by an individual depends on their age and the number of infectious mosquito bites they have received.
