    Biophysical and physiological processes causing oxygen loss from coral reefs

    Cynthia B Silveira et al.
    Coral reef heterotrophic bacteria and fleshy macroalgae cause oxygen loss from reef systems through microbial biomass accumulation and ebullition from algae surfaces.

    AMPK signaling to acetyl-CoA carboxylase is required for fasting- and cold-induced appetite but not thermogenesis

    Sandra Galic et al.
    A single mutation in acetyl-CoA carboxylase blocking AMPK regulation inhibits food intake in mice in response to cold exposure or fasting causing them to lose weight.

    Insight into the evolution of microbial metabolism from the deep-branching bacterium, Thermovibrio ammonificans

    Donato Giovannelli et al.
    The genome of Thermovibrio ammonificans encodes ancestral pathways (e.g., hydrogen oxidation) and more recently acquired ones (e.g., nitrate reduction) and a hybrid pathway for CO2 fixation.

    The Drosophila HNF4 nuclear receptor promotes glucose-stimulated insulin secretion and mitochondrial function in adults

    William E Barry, Carl S Thummel
    Drosophila HNF4 directs a developmental switch at the onset of adulthood that suppresses diabetes by promoting mitochondrial function and supporting glucose-stimulated insulin secretion.

    A comprehensive search for calcium binding sites critical for TMEM16A calcium-activated chloride channel activity

    Jason Tien et al.
    The identification of four acidic amino acids as potential calcium-binding residues in the TMEM16A calcium-activated chloride channel furthers the molecular understanding of this ion channel family.

    The inhibitory microcircuit of the substantia nigra provides feedback gain control of the basal ganglia output

    Jennifer Brown et al.
    Negative feedback signals within the substantia nigra regulate the output of the basal ganglia, with implications for disorders such as Parkinson's disease.

    Phenotype-based cell-specific metabolic modeling reveals metabolic liabilities of cancer

    Keren Yizhak et al.
    Genome-scale metabolic modeling of individual cancer cells and healthy human cells identifies specific and selective metabolic vulnerabilities.

    The half-life of the bone-derived hormone osteocalcin is regulated through O-glycosylation in mice, but not in humans

    Omar Al Rifai et al.
    In mice, but not in humans, the bone-derived hormone osteocalcin is O-glycosylated, a post-translational modification controlling its half-life in vivo.

    Hippocampal low-frequency stimulation prevents seizure generation in a mouse model of mesial temporal lobe epilepsy

    Enya Paschen et al.
    Optogenetic and electrical low-frequency stimulation in the sclerotic hippocampus prevents the emergence of spontaneous focal and evoked generalized seizures in a mouse epilepsy model.

    Cytotoxic T cells swarm by homotypic chemokine signalling

    Jorge Luis Galeano Niño et al.
    Killer T cells swarm around tumour targets by accelerating the recruitment of distant T cells, which upon arrival and target engagement augment the chemotactic signal in a positive feedback loop.
