    Reduced metabolism supports hypoxic flight in the high-flying bar-headed goose (Anser indicus)

    Jessica U Meir et al.
    Measurements of bar-headed geese flying in a wind tunnel in hypoxia reveal that these birds sustain aerobic flight at high altitude via a reduction in metabolism.

    Physiology: The highs and lows of bird flight

    Jon Harrison
    Bar-headed geese lower their flight metabolic rates to fly in low-oxygen conditions.

    Membrane characteristics tune activities of endosomal and autophagic human VPS34 complexes

    Yohei Ohashi et al.
    The lipid kinase VPS34 complexes I and II are both activated by unsaturation of substrate and non-substrate lipids, curvature, electrostatics and polyphosphoinositides, which play roles in localisation and cellular function.

    Regulation of nerve growth and patterning by cell surface protein disulphide isomerase

    Geoffrey MW Cook et al.
    The nerve growth-repellent activity that generates spinal nerve repeat-patterning in birds and mammals is identified at the molecular level, and a similar system is revealed in adult brain grey matter.

    Limited dishevelled/Axin oligomerization determines efficiency of Wnt/β-catenin signal transduction

    Wei Kan et al.
    In vitro and in cellulo characterization of oligomerization by the cytoplasmic Wnt effector dishevelled and its partner Axin provide new mechanistic principles for Wnt/β-catenin signaling.

    Translational control of one-carbon metabolism underpins ribosomal protein phenotypes in cell division and longevity

    Nairita Maitra et al.
    Extensive molecular profiling shows how loss of highly similar, paralogous ribosomal proteins lead to distinct phenotypic outputs, through translational control of specific mRNAs.

    Tuning movement for sensing in an uncertain world

    Chen Chen et al.
    Animals work in a world full of surprises, where using energy to position sensors proportional to the location's expected information avoids the pitfalls of positioning them at the information maxima.

    Convergent changes in muscle metabolism depend on duration of high-altitude ancestry across Andean waterfowl

    Neal J Dawson et al.
    Changes in pathways of lipid oxidation, glycolysis, and mitochondrial oxidative phosphorylation are common strategies to cope with high-altitude hypoxia, but some changes require longer evolutionary time to arise.

    Aberrant sorting of hippocampal complex pyramidal cells in type I lissencephaly alters topological innervation

    James A D'Amour et al.
    The loss of lamination in mammalian brain structures under cellular heterotopia carries with it non-uniform ramifications for the various components of the canonical CA1 microcircuitry.

    Neural activity in a hippocampus-like region of the teleost pallium is associated with active sensing and navigation

    Haleh Fotowat et al.
    Sparse firing in a hippocampus-like structure of the teleost telencephalon is linked to spatial navigation and active sensing.
