    The mobility of packaged phage genome controls ejection dynamics

    Alex Evilevitch
    Temperature and ionic conditions control the mechanical properties of virally encapsidated DNA and act as a switch between synchronized and desynchronized genome ejection dynamics in a phage population.

    Phase transitions of multivalent proteins can promote clustering of membrane receptors

    Sudeep Banjade, Michael K Rosen
    A new and general mechanism describes the organization of membrane proteins and their cytoplasmic ligands into micrometer-scale clusters, based on polymerization and concomitant phase separation of multivalent proteins.

    A pH-driven transition of the cytoplasm from a fluid- to a solid-like state promotes entry into dormancy

    Matthias Christoph Munder et al.
    The cytoplasm behaves as an adaptable fluid that can reversibly transition into a protective solid-like state upon stress.

    Greatwall-phosphorylated Endosulfine is both an inhibitor and a substrate of PP2A-B55 heterotrimers

    Byron C Williams et al.
    The mechanism of inhibition by unfair competition is central to determining the protein phosphorylation states that govern cell cycle transitions between M phase and interphase.

    Aurkb/PP1-mediated resetting of Oct4 during the cell cycle determines the identity of embryonic stem cells

    Jihoon Shin et al.
    The regulation of the core transcription factor Oct4 by the Aurkb-PP1 axis links the cell cycle to pluripotency programs in embryonic stem cells.

    Distinct stages in stress granule assembly and disassembly

    Joshua R Wheeler et al.
    A new stress granule assembly mechanism has implications for other RNP granules and pathological aggregates.

    Mesoscale phase separation of chromatin in the nucleus

    Gaurav Bajpai et al.
    Computer simulations show transitions between novel types of chromatin organization (peripheral, central, conventional) depending on chromatin interactions with itself, the lamin and nuclear hydration, measured in recent experiments.

    Spatial control of translation repression and polarized growth by conserved NDR kinase Orb6 and RNA-binding protein Sts5

    Illyce Nuñez et al.
    NDR kinase Orb6 prevents RNP granule assembly and translational repression by promoting Sts5 association with 14-3-3 protein Rad24 to spatially control polarized cell growth.

    Bacterial cell cycle control by citrate synthase independent of enzymatic activity

    Matthieu Bergé et al.
    A key enzyme of central energy metabolism, citrate synthase, regulates bacterial cell cycle progression at a very specific stage (S-phase) and independently of its enzymatic activity.

    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.
