    Morphometric analysis of lungfish endocasts elucidates early dipnoan palaeoneurological evolution

    Alice M Clement, Tom J Challands ... John A Long
    Cranial endocasts of fossil and extant lungfish, analysed via tomography and novel principle component analyses designed for use with missing data, show that lungfish forebrain and inner ear regions show the most variation in brain shape evolution through time.

    Distinct roles for two Caenorhabditis elegans acid-sensing ion channels in an ultradian clock

    Eva Kaulich, Trae Carroll ... Denise S Walker
    Two acid-sensing members of the degenerin/epithelial sodium channel family play distinct roles in controlling different aspects of rhythmic proton and calcium oscillations in the nematode intestine.

    Reversal of ApoE4-induced recycling block as a novel prevention approach for Alzheimer’s disease

    Xunde Xian, Theresa Pohlkamp ... Joachim Herz
    Lowering endosomal pH through inhibition of sodium-hydrogen exchanger 6 corrects the ApoE4-induced Reelin resistance and restores neuronal glutamate receptor trafficking.

    Phylogenomics of white-eyes, a ‘great speciator’, reveals Indonesian archipelago as the center of lineage diversity

    Chyi Yin Gwee, Kritika M Garg ... Frank E Rheindt
    Contrary to the high absolute number of white-eyes in other parts of the world, the Indonesian archipelago is the center of phylogenetic diversity of this great speciator.

    Nuclear genomic signals of the ‘microturbellarian’ roots of platyhelminth evolutionary innovation

    Christopher E Laumer, Andreas Hejnol, Gonzalo Giribet
    A phylogeny of all major groups of flatworms based on hundreds of genes sheds new light the early evolution of this important metazoan phylum, with particular significance for the original of vertebrate parasitism.

    DeepPoseKit, a software toolkit for fast and robust animal pose estimation using deep learning

    Jacob M Graving, Daniel Chae ... Iain D Couzin
    A new deep-learning software toolkit with general-purpose methods for quickly and reliably measuring the full body posture of animals directly from images or videos without physical markers.

    Endogenous tagging using split mNeonGreen in human iPSCs for live imaging studies

    Mathieu C Husser, Nhat P Pham ... Alisa Piekny
    The split mNeonGreen system enables fast and efficient endogenous tagging in human iPSCs and facilitates the study of proteins in human stem cells and differentiated cells by live imaging.

    Live imaging and biophysical modeling support a button-based mechanism of somatic homolog pairing in Drosophila

    Myron Barber Child VI, Jack R Bateman ... Hernan G Garcia
    Biophysical modeling and quantitative live-cell imaging converge to show that the century-old puzzle of somatic homolog pairing in Drosophila operates via a button model.

    Dynamically evolving novel overlapping gene as a factor in the SARS-CoV-2 pandemic

    Chase W Nelson, Zachary Ardern ... Xinzhu Wei
    A novel, overlapping, putatively functional gene in SARS-CoV-2, ORF3d, is absent from close relatives of SARS-CoV-2 and may have contributed to the biology, emergence, or spread of the virus.

    Presynaptic APP levels and synaptic homeostasis are regulated by Akt phosphorylation of huntingtin

    Julie Bruyère, Yah-Se Abada ... Frédéric Saudou
    Reducing Akt-mediated huntingtin phosphorylation decreases APP accumulation at the synapse by reducing its anterograde axonal transport and ameliorates learning and memory in a mouse model of familial Alzheimer disease.
