    Gating of neural error signals during motor learning

    Rhea R Kimpo et al.
    Electrode recordings and optogenetics reveal that the cerebellum can modulate its response to error signals from the brainstem during motor learning.

    Differential impact of self and environmental antigens on the ontogeny and maintenance of CD4+ T cell memory

    Thea Hogan et al.
    Comparing mice in clean and dirty environments reveals that environment drives initial establishment and size of T cell memory compartments, but not their maintenance in adults.

    CryoEM and computer simulations reveal a novel kinase conformational switch in bacterial chemotaxis signaling

    C Keith Cassidy et al.
    An atomic model of the bacterial chemosensory array obtained through the synthesis of cryo-electron tomography and large-scale molecular-dynamics simulations reveals a new kinase conformation during signaling events.

    Narrow equilibrium window for complex coacervation of tau and RNA under cellular conditions

    Yanxian Lin et al.
    Liquid-liquid phase separation of tau is demonstrated to be an equilibrium state, stable only within a narrow range near physiological conditions, and thus has the capacity to regulate biological processes.

    Paternal nicotine exposure alters hepatic xenobiotic metabolism in offspring

    Markus P Vallaster et al.
    A novel paternal effect based on nicotine exposure reveals that offspring exhibit an adaptive, yet nonspecific, resistance to multiple toxins.

    Crystal structure and dynamics of a lipid-induced potential desensitized-state of a pentameric ligand-gated channel

    Sandip Basak et al.
    Polyunsaturated fatty acids enhance desensitization in pentameric ligand-gated ion channels.

    c-di-GMP heterogeneity is generated by the chemotaxis machinery to regulate flagellar motility

    Bridget R Kulasekara et al.
    Real time measurements of c-di-GMP in individual cells reveal an unexpected mechanism by which the chemotaxis machinery controls c-di-GMP heterogeneity, thereby regulating flagellar-based motility.

    Acetylcholine acts on songbird premotor circuitry to invigorate vocal output

    Paul I Jaffe, Michael S Brainard
    The neuromodulator acetylcholine contributes to state-dependent modulation of motor vigor and variability by direct action on songbird premotor cortex, bypassing basal ganglia circuitry.

    Structure of the germline genome of Tetrahymena thermophila and relationship to the massively rearranged somatic genome

    Eileen P Hamilton et al.
    The model organism Tetrahymena thermopile carries two nuclei with distinct genomes: an unrearranged germline genome with five chromosomes, and a somatic genome reduced in size by a third and with 181 chromosomes.

    MELK is not necessary for the proliferation of basal-like breast cancer cells

    Hai-Tsang Huang et al.
    The inhibitory or deletion effect of MELK does not impair the proliferation of basal-like breast cancer cell lines.
