    Altered regulation of Ia afferent input during voluntary contraction in humans with spinal cord injury

    Bing Chen, Monica A Perez
    Physiological analysis reveals that during voluntary contraction Ia afferent input have a lesser facilitatory effect on motor neurons in humans with chronic incomplete spinal cord injury compared with control subjects.

    GJA1 depletion causes ciliary defects by affecting Rab11 trafficking to the ciliary base

    Dong Gil Jang, Keun Yeong Kwon ... Tae Joo Park
    Ciliogenesis requires a gap junction protein (GJA1) mediated ciliary vesicle deposition and CP110 removal.

    An increase of inhibition drives the developmental decorrelation of neural activity

    Mattia Chini, Thomas Pfeffer, Ileana Hanganu-Opatz
    The age-dependent shift of prefrontal excitation-inhibition (E-I) ratio toward inhibition causes sparser and decorrelated activity, while its impairment might relate to neurodevelopmental disorders.

    Structural model of microtubule dynamics inhibition by kinesin-4 from the crystal structure of KLP-12 –tubulin complex

    Shinya Taguchi, Juri Nakano ... Ryo Nitta
    Structural, functional, and genetic analyses reveal how kinesin-4 motor KLP-12 precisely modulates the curvature of the microtubule plus-end to inhibit the microtubule dynamics for achieving the proper length control of axons.

    Recovering mixtures of fast-diffusing states from short single-particle trajectories

    Alec Heckert, Liza Dahal ... Xavier Darzacq
    Tracking proteins in live cells is challenging due to technical limitations and biological complexity, but approaches based in Bayesian nonparametrics stand a decent chance at recovering a target protein's dynamic profile from noisy data.

    Proton-transporting heliorhodopsins from marine giant viruses

    Shoko Hososhima, Ritsu Mizutori ... Hideki Kandori
    A viral heliorhodopsin from Emiliania huxleyi virus 202 (V2HeR3) is a light-activated proton transporter, which has the potential to depolarize the host cells by light, possibly to overcome the host defense mechanisms or to prevent superinfection.

    β-cell deletion of the PKm1 and PKm2 isoforms of pyruvate kinase in mice reveals their essential role as nutrient sensors for the KATP channel

    Hannah R Foster, Thuong Ho ... Matthew J Merrins
    Local ATP production by the plasma membrane-associated glycolytic enzyme pyruvate kinase is essential for the nutrient-dependent closure of the ATP-sensitive potassium channels that initiate insulin release from pancreatic β-cells.

    Stereotyped behavioral maturation and rhythmic quiescence in C. elegans embryos

    Evan L Ardiel, Andrew Lauziere ... Hari Shroff
    Systematic analysis of behavioral maturation in the Caenorhabditis elegans embryo reveals a stereotyped developmental progression, including rhythmic behavioral quiescence elicited by a sleep-promoting neuron (RIS) releasing somnogenic peptides (FLP-11).

    Artificial selection methods from evolutionary computing show promise for directed evolution of microbes

    Alexander Lalejini, Emily Dolson ... Luis Zaman
    Multiobjective artificial selection methods from evolutionary computing show promise for improving directed evolution outcomes when selecting for multiple traits of interest.

    Core genes can have higher recombination rates than accessory genes within global microbial populations

    Asher Preska Steinberg, Mingzhi Lin, Edo Kussell
    Homologous recombination rates tend to be highest in the most conserved parts of bacterial genomes.
