    Role of framework mutations and antibody flexibility in the evolution of broadly neutralizing antibodies

    Victor Ovchinnikov, Joy E Louveau ... Arup K Chakraborty
    Computer simulations of the evolution of broadly neutralizing antibodies against HIV suggest that non-traditional pathways involving framework mutations which lead initially to increased antibody flexibility do occur, but can be avoided by appropriate vaccine design.

    Gene-free methodology for cell fate dynamics during development

    Francis Corson, Eric D Siggia
    Mathematical methods based on geometry that directly embody the developmental concepts of competency, commitment, and determination provide succinct descriptions of morphogenesis and allow quantitative predictions from fits to sparse genetic data in Caenorhabditis elegans.

    Mechanism of bidirectional thermotaxis in Escherichia coli

    Anja Paulick, Vladimir Jakovljevic ... Victor Sourjik
    The interplay between the opposing responses mediated by different chemoreceptors enables bacteria to swim towards a preferred temperature.

    Physical limits of flow sensing in the left-right organizer

    Rita R Ferreira, Andrej Vilfan ... Julien Vermot
    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.

    Increasing evidence of mechanical force as a functional regulator in smooth muscle myosin light chain kinase

    Fabian Baumann, Magnus Sebastian Bauer ... Hermann Eduard Gaub
    Atomic force microscopy based single-molecule force spectroscopy of smooth muscle myosin light chain kinase strongly indicates the existence of a mechanically triggerable activation pathway analogous to its well-established biochemical regulation pathway via calcium-loaded calmodulin.

    Probing protein flexibility reveals a mechanism for selective promiscuity

    Nicolas A Pabon, Carlos J Camacho
    Conserved contacts on cognate ligands trigger an induced fit pathway that confers selective promiscuity to PD-1, a flexible regulatory protein and promising anticancer target.

    Microbial consortia at steady supply

    Thibaud Taillefumier, Anna Posfai ... Ned S Wingreen
    In a consumer-resource model obeying the physical requirement of flux conservation, metabolic competition between microbes yields consortia of cell types that collectively resist invasion via optimal use of resources.

    27 T ultra-high static magnetic field changes orientation and morphology of mitotic spindles in human cells

    Lei Zhang, Yubin Hou ... Xin Zhang
    An ultra-high static magnetic field changes mitotic spindle orientation in cells by exerting magnetic torques on both microtubules and chromosomes.

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

    Xuemeng Zhang, Thomas Kampourakis ... Yin-Biao Sun
    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.
