    Cell-wall remodeling drives engulfment during Bacillus subtilis sporulation

    Nikola Ojkic et al.
    Imaging experiments and simulations reveal that the biophysical mechanism for force generation needed to engulf a forespore is based on coordinated cell wall synthesis and degradation.

    Motor control of Drosophila feeding behavior

    Olivia Schwarz et al.
    The neuroanatomical and functional analysis of genetically-identified motoneurons controlling all major steps of Drosophila proboscis extension provides new insights into the architecture of a motor circuitry controlling a reaching-like behavior.

    Regulation by the quorum sensor from Vibrio indicates a receptor function for the membrane anchors of adenylate cyclases

    Stephanie Beltz et al.
    A canonical class III adenylate cyclase with a membrane anchor of six transmembrane spans is regulated by a receptor of similar design, the quorum-sensing receptor from Vibrio harveyi.

    Genetic screen in Drosophila muscle identifies autophagy-mediated T-tubule remodeling and a Rab2 role in autophagy

    Naonobu Fujita et al.
    Analyses of a developmentally regulated Drosophila myofiber remodeling program provide insight into induced autophagy required for T-tubule membrane reorganization, and uncover a conserved Rab2 role in autophagosome-lysosome fusion.

    Two-way communication between SecY and SecA suggests a Brownian ratchet mechanism for protein translocation

    William John Allen et al.
    Evidence is presented that supports a completely new, diffusion-driven mechanism for transporting proteins across membranes in bacteria.

    Inhibitory peptidergic modulation of C. elegans serotonin neurons is gated by T-type calcium channels

    Kara E Zang et al.
    Genetic analysis of how neuropeptides control C. elegans reproductive behavior shows how T-type calcium channels engage and disengage target neurons from these critical regulators of neural circuits and behavior.

    Curvature-induced expulsion of actomyosin bundles during cytokinetic ring contraction

    Junqi Huang et al.
    Cytokinetic actomyosin ring disassembly occurs through a novel mechanism in which the increased ring curvature, generated through contraction, itself promotes the disassembly process.

    A Fyn biosensor reveals pulsatile, spatially localized kinase activity and signaling crosstalk in live mammalian cells

    Ananya Mukherjee et al.
    Unique biosensor design and protein-engineering enables direct visualization of the active form of Fyn kinase with high specificity, minimal perturbation and shows cellular signaling to be compartmentalized and pulsatile.

    Medial entorhinal cortex activates in a traveling wave in the rat

    J Jesús Hernández-Pérez et al.
    The existence of traveling waves in the medial entorhinal cortex, like those observed in the hippocampus, supports the hypothesis that traveling waves coordinate the activity of anatomically distributed circuits.

    Length-dependent disassembly maintains four different flagellar lengths in Giardia

    Shane G McInally et al.
    Giardia, a multi-ciliated parasitic protist, maintains four different flagellar lengths by balancing flagellar length-independent IFT-mediated assembly with length-dependent kinesin-13 mediated disassembly.
