    Factors affecting template switch recombination associated with restarted DNA replication

    Manisha Jalan et al.
    Genomic deletions and gene conversions, caused by template switching associated with restarted DNA replication, are detected downstream of a collapsed replication fork and are suppressed by several conserved DNA helicases.

    The role of scaffold reshaping and disassembly in dynamin driven membrane fission

    Martina Pannuzzo et al.
    Computational modeling of a dynamin-constricted membrane neck can rank proposed shape changes of the helical scaffold in terms of their fission aptitude and elucidate the associated pathways.

    FGF21 trafficking in intact human cells revealed by cryo-electron tomography with gold nanoparticles

    Maia Azubel et al.
    Specific attachment of molecularly defined gold nanoparticles enables precise localization, critical for structural studies in vivo, of proteins of unknown structure within the cellular milieu by cryo-electron tomography.

    Mechanical force regulates tendon extracellular matrix organization and tenocyte morphogenesis through TGFbeta signaling

    Arul Subramanian et al.
    Perturbation of mechanical force at muscle attachments and its effects on tendon morphogenesis provides insights into the mechanisms underlying cellular responses to tensional force and resulting extracellular matrix production.

    Spatial patterning of liver progenitor cell differentiation mediated by cellular contractility and Notch signaling

    Kerim B Kaylan et al.
    Mechanical stress plays a cooperative role with Notch in biliary differentiation of liver progenitors, supporting a model of liver development in which biomechanical cues are key inducers of cell fate.

    Chronology of motor-mediated microtubule streaming

    Arvind Ravichandran et al.
    Microtubule streaming driven by molecular motors covers characteristic times that span several orders of magnitude from fast, single-microtubule sliding on molecular scales to slow, collective motion on cellular scales.

    Schwann cells, but not Oligodendrocytes, Depend Strictly on Dynamin 2 Function

    Daniel Gerber et al.
    In the peripheral nervous system, the large GTPase dynamin 2 is required for Schwann cell survival, developmental radial sorting of axons, myelination, and myelin maintenance.

    Structured illumination microscopy combined with machine learning enables the high throughput analysis and classification of virus structure

    Romain F Laine et al.
    Machine learning in conjunction with super-resolution imaging allows for the first time to quantitatively analyse large and heterogenous virus samples structure at a high throughput and specificity.

    Muscle-specific stress fibers give rise to sarcomeres in cardiomyocytes

    Aidan M Fenix et al.
    Sarcomeres in heart muscle cells come from stress fiber-like structures that are mechanistically distinct from stress fibers in non-muscle cells.

    Downsizing the molecular spring of the giant protein titin reveals that skeletal muscle titin determines passive stiffness and drives longitudinal hypertrophy

    Ambjorn Brynnel et al.
    Genetically altering the size of the molecular spring element in the giant protein titin established that titin determines the stiffness of skeletal muscle and the number of sarcomeres in series.
