    Two mechanisms regulate directional cell growth in Arabidopsis lateral roots

    Charlotte Kirchhelle et al.
    In lateral roots, cells employ a novel pathway to cell edges to control directional growth, which acts independently of the leading paradigm of oriented deposition of cellulose microfibrils at faces.

    Pre-transition effects mediate forces of assembly between transmembrane proteins

    Shachi Katira et al.
    A general mechanism for how powerful forces of assembly and protein mobility can emerge from phase transitions is established.

    Cortical regulation of cell size by a sizer cdr2p

    Kally Z Pan et al.
    It is shown that fission yeast cells sense their size by measuring their surface area through a membrane-associated sizer protein cdr2p.

    Meiotic cellular rejuvenation is coupled to nuclear remodeling in budding yeast

    Grant A King et al.
    A meiotic nuclear remodeling event mediates cellular rejuvenation through elimination of senescence factors.

    An ESCRT-LEM protein surveillance system is poised to directly monitor the nuclear envelope and nuclear transport system

    David J Thaller et al.
    ESCRT-driven mechanisms that sense and seal holes in the nuclear membranes directly monitor the nuclear transport system and the exposure of the inner nuclear membrane.

    Node of Ranvier length as a potential regulator of myelinated axon conduction speed

    I Lorena Arancibia-Cárcamo et al.
    Node of Ranvier length is similar at successive nodes along single myelinated CNS axons, but differs between axons, and could potentially be tuned to adjust the conduction velocity of each axon.

    A non-linear system patterns Rab5 GTPase on the membrane

    Alice Cezanne et al.
    Both protein-protein and protein-lipid interactions are essential for Rab5 symmetry breaking at the early endosome.

    Identification of a lipid scrambling domain in ANO6/TMEM16F

    Kuai Yu et al.
    The amino acids that are necessary for phospholipid scrambling by ANO6/TMEM16F can, via domain swapping, confer scrambling activity to the chloride ion channel ANO1 that normally does not scramble phospholipids.

    Role of competition between polarity sites in establishing a unique front

    Chi-Fang Wu et al.
    In budding yeast, nascent polarity sites engage in a winner-takes-all contest to determine a single front.

    Competitive coordination of the dual roles of the Hedgehog co-receptor in homophilic adhesion and signal reception

    Shu Yang et al.
    The apparently incompatible functions of the Hedgehog co-receptor Ihog in homophilic adhesion and ligand binding cooperate in Hh transport and reception.
