    Universally high transcript error rates in bacteria

    Weiyi Li, Michael Lynch
    Fundamental details of the rate and molecular spectrum of transcript errors were revealed in four bacterial species, providing novel insights into transcriptional fidelity and RNA quality-control in prokaryotes.

    Single-cell transcriptome reveals the novel role of T-bet in suppressing the immature NK gene signature

    Chao Yang et al.
    T-bet suppresses the expression of immature NK cell-defining genes.

    Principles of operation of a cerebellar learning circuit

    David J Herzfeld et al.
    Quantitative analysis of behavior coupled with computational modeling reveal the set of circuit-level principles that underlie cerebellar-dependent motor learning in smooth pursuit eye movements of monkeys across timescales.

    A tudor domain protein, SIMR-1, promotes siRNA production at piRNA-targeted mRNAs in C. elegans

    Kevin I Manage et al.
    SIMR-1 acts downstream of the piRNA pathway to promote siRNA amplification by the Mutator complex and localizes to perinuclear foci distinct from Mutator foci, P granules and Z granules.

    Effects of fluorescent glutamate indicators on neurotransmitter diffusion and uptake

    Moritz Armbruster et al.
    Fluorescent glutamate indicators distort the time course of neurotransmitter diffusion and uptake by competing with transporters, an important caveat to consider when using iGluSnFR and its analogs.

    Distinct mitochondrial defects trigger the integrated stress response depending on the metabolic state of the cell

    Eran Mick et al.
    Mitochondrial electron transport chain dysfunction triggers the integrated stress response due to an asparagine deficiency downstream of impaired NADH oxidation in proliferating myoblasts, but not in differentiated myotubes.

    Identifying the immune interactions underlying HLA class I disease associations

    Bisrat J Debebe et al.
    HLA class I-disease associations have been studied for decades; a new approach for investigating the underlying mechanism can overcome past problems with interpretation and help to understand the etiology of human diseases.

    A CLC-ec1 mutant reveals global conformational change and suggests a unifying mechanism for the CLC Cl/H+ transport cycle

    Tanmay S Chavan et al.
    Crystallography together with electron-resonance spectroscopy, molecular-dynamics simulations, and transport measurements reveal the molecular details of protein conformational change, and how this change contributes to function in a CLC-type chloride/proton exchanger.

    IP3 mediated global Ca2+ signals arise through two temporally and spatially distinct modes of Ca2+ release

    Jeffrey T Lock, Ian Parker
    Cell-wide Ca2+ signals that regulate numerous cellular functions comprise dual Ca2+ release modes through IP3 receptors, punctate transients mediated by clustered receptors and spatiotemporally diffuse release through functionally distinct receptors.

    The Warburg Effect and lactate signaling augment Fgf-MAPK to promote sensory-neural development in the otic vesicle

    Husniye Kantarci et al.
    Glycolysis is locally enhanced and redirected in zebrafish to generate lactate, which functions as a signaling molecule to fully activate Fgf target genes required for proper sensory and neural development.
