    Mutations that improve efficiency of a weak-link enzyme are rare compared to adaptive mutations elsewhere in the genome

    Andrew B Morgenthaler, Wallis R Kinney ... Shelley D Copley
    Mutations elsewhere in the genome play critical roles in improving fitness during amplification and divergence of a gene encoding a weak-link enzyme whose inefficiency limits growth rate.

    Uncovering the functional anatomy of the human insula during speech

    Oscar Woolnough, Kiefer James Forseth ... Nitin Tandon
    Direct insular recordings in humans reveal that contrary to several prominent models of speech production, it is not engaged in pre-articulatory planning, but in auditory and somatosensory components of speech.

    A terminal selector prevents a Hox transcriptional switch to safeguard motor neuron identity throughout life

    Weidong Feng, Yinan Li ... Paschalis Kratsios
    A molecular mechanism that involves highly conserved transcription factors enables cholinergic motor neurons of the nematode Caenorhabditis elegans to become and remain functional.

    Axon-like protrusions promote small cell lung cancer migration and metastasis

    Dian Yang, Fangfei Qu ... Julien Sage
    In small cell lung cancer, the transition from a neuroendocrine state to a more neuronal state endows these cancer cells with increased migration and metastatic potential.
    1. Neuroscience

    Amyloid and tau accumulate across distinct spatial networks and are differentially associated with brain connectivity

    Joana B Pereira, Rik Ossenkoppele ... Oskar Hansson
    The amyloid patterns overlap with the default-mode network, whereas the tau patterns overlap with distinct functional networks and are associated with a loss of anatomical connectivity and multiple cognitive functions.

    Opioids modulate an emergent rhythmogenic process to depress breathing

    Xiaolu Sun, Carolina Thörn Pérez ... Kaiwen Kam
    Inspiratory rhythmogenesis is mediated by an emergent mechanism independent of bursts associated with motor output and is modulated by opioids, pointing to strategies for ameliorating opioid-induced respiratory depression.

    Homeostasis of branched-chain amino acids is critical for the activity of TOR signaling in Arabidopsis

    Pengfei Cao, Sang-Jin Kim ... Federica Brandizzi
    Despite BCAAs being de novo-synthesized in chloroplasts, TOR activation by BCAAs is conserved in plants and triggers a re-organization of actin and actin-associated endomembranes.

    High fat diet induces microbiota-dependent silencing of enteroendocrine cells

    Lihua Ye, Olaf Mueller ... John F Rawls
    Enteroendocrine cells sense nutrients in the gut and regulate digestive physiology but are rendered insensitive following fat ingestion due to alteration of gut microbiota.

    Tritrophic metabolism of plant chemical defenses and its effects on herbivore and predator performance

    Ruo Sun, Xingcong Jiang ... Daniel Giddings Vassão
    Genetic manipulation demonstrates the costs and benefits of detoxifying glucosinolate plant defenses in a pest insect and its predator.

    Ribosome biogenesis restricts innate immune responses to virus infection and DNA

    Christopher Bianco, Ian Mohr
    Ribosome production is unexpectedly integrated into innate cell-intrinsic responses that regulate double strand DNA-sensing and inflammatory cytokine induction in infected and uninfected cells.
