    Arid1b haploinsufficient mice reveal neuropsychiatric phenotypes and reversible causes of growth impairment

    Cemre Celen et al.
    Mirroring human patients with ARID1B mutations, Arid1b haploinsufficient mice exhibited numerous neuropsychiatric defects and revealed IGF1 deficiency related growth impairment that could be ameliorated with growth hormone supplementation.

    Vascular control of the CO2/H+-dependent drive to breathe

    Colin M Cleary et al.
    Understanding how loss of CO2/H+ vascular reactivity affects respiratory control may facilitate development of treatments for breathing problems in this population.

    Eukaryotic translation initiation factor 3 plays distinct roles at the mRNA entry and exit channels of the ribosomal preinitiation complex

    Colin Echeverría Aitken et al.
    Eukaryotic translation initiation factor 3 (eIF3) is required to stabilize the binding of mRNA at the exit channel of the small ribosomal subunit and acts at the entry channel to accelerate mRNA recruitment to the translation preinitiation complex.

    Origins and functional consequences of somatic mitochondrial DNA mutations in human cancer

    Young Seok Ju et al.
    Identifying 1,907 mitochondrial somatic mutations from 1,675 tumor tissues provides new insights into the causes and effects of the mitochondrial genome mutations found in human cancers.

    The Ca2+ transient as a feedback sensor controlling cardiomyocyte ionic conductances in mouse populations

    Colin M Rees et al.
    Feedback sensing of the intracellular calcium concentration suffices to reproduce the diversity of ionic conductances underlying normal cardiac electromechanical function in a genetically diverse population of mice.

    Somatostatin-expressing parafacial neurons are CO2/H+ sensitive and regulate baseline breathing

    Colin M Cleary et al.
    Cellular and chemogenetic approaches identify a novel mode of chemotransduction involving regulation of basal breathing by CO2/H+-dependent disinhibition.

    Virology: Pushing the envelope

    Julia H Wildschutte, John M Coffin
    Primates have co-opted a viral gene to produce an envelope protein that prevents infection by the HERV-T virus and likely contributed to the extinction of this virus.

    Reverse evolution leads to genotypic incompatibility despite functional and active site convergence

    Miriam Kaltenbach et al.
    Enzyme evolution is reversible on a structural and functional (phenotypic) level, but through a different mutational pathway that leads to genotypic incompatibility with the ancestor.

    Spatiotemporal mosaic self-patterning of pluripotent stem cells using CRISPR interference

    Ashley RG Libby et al.
    Dynamic control of intrinsic pluripotent multicellular self-organization to yield robust symmetry breaking patterns that recapitulate morphogenic processes associated with developmental events.

    Predicting evolution from the shape of genealogical trees

    Richard A Neher et al.
    A general method for inferring fitness from a sample of nucleotide sequences can predict the progenitor of next year's seasonal influenza.
