    Distinct contributions of the thin and thick filaments to length-dependent activation in heart muscle

    Xuemeng Zhang et al.
    The Frank–Starling law of the heart and its underlying mechanism of length-dependent activation involve distinctive structural changes in both the thin and thick filaments of cardiac muscle cells.

    Controlling contractile instabilities in the actomyosin cortex

    Masatoshi Nishikawa et al.
    Combining quantitative biological experiment and physical description of actomyosin cortex reveals a contractile instability in the cortex of C. elegans embryo, and its biochemical control in order to robustly drive morphogenetic events.

    Mapping out Min protein patterns in fully confined fluidic chambers

    Yaron Caspi, Cees Dekker
    The geometry selection rules of dynamic Min protein patterns are determined in fully confined fluidic chambers, showing that both oscillations and running waves are derivatives of spiral rotations that are established as the majority pattern.

    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.

    Aerotaxis in the closest relatives of animals

    Julius B Kirkegaard et al.
    The colony-forming choanoflagellate Salpingoeca rosetta is capable of moving towards oxygen using logarithmic sensing of oxygen concentrations and a navigation strategy that involves random movements.

    Cortical flow aligns actin filaments to form a furrow

    Anne-Cecile Reymann et al.
    Compressing the actomyosin network by cortical flow causes filaments to align and form a constricting ring.

    Overall energy conversion efficiency of a photosynthetic vesicle

    Melih Sener et al.
    The overall energy conversion efficiency is calculated for a bacterial vesicle that harvests solar energy for ATP production on the basis of an atomic-detail structural model.

    Direct mechanical stimulation of tip links in hair cells through DNA tethers

    Aakash Basu et al.
    The ability of hair cells to produce an electrical signal in response to a mechanical stimulus stems from tension in the elastic tip links within the bundles.
