    Gene regulatory patterning codes in early cell fate specification of the C. elegans embryo

    Alison G Cole, Tamar Hashimshony ... Itai Yanai
    The transcriptomes of individual cells of the 1- to 102-cell stages in Caenorhabditis elegans embryogenesis are identified along with 119 embryonic cell states during cell fate specification, including ‘equivalence-group’ cell identities.

    Gene expression mapping of the neuroectoderm across phyla – conservation and divergence of early brain anlagen between insects and vertebrates

    Nico Posnien, Vera S Hunnekuhl, Gregor Bucher
    Hypotheses on brain homologies between insects and vertebrates are tested by comparing gene expression patterns from flies and beetles with those from vertebrates at early neuroectoderm stages.

    Synchronous multi-segmental activity between metachronal waves controls locomotion speed in Drosophila larvae

    Yingtao Liu, Eri Hasegawa ... Hiroshi Kohsaka
    GABAergic interneurons coordinate synchronous muscle contractions along the length of the fruit fly larva to control the duration between peristaltic waves and locomotion speed.

    Sensory conflict disrupts circadian rhythms in the sea anemone Nematostella vectensis

    Cory A Berger, Ann M Tarrant
    Misalignment between light and temperature cycles leads to disrupted circadian behavior and a substantially altered rhythmic transcriptome.

    Generative network modeling reveals quantitative definitions of bilateral symmetry exhibited by a whole insect brain connectome

    Benjamin D Pedigo, Mike Powell ... Joshua T Vogelstein
    Novel statistical tests to compare networks enable the evaluation of mathematical definitions of left/right symmetry in a larval Drosophila brain connectome.

    AGS3 antagonizes LGN to balance oriented cell divisions and cell fate choices in mammalian epidermis

    Carlos P Descovich, Kendall J Lough ... Scott E Williams
    A proper balance of planar and perpendicular balances is critical to establishing proper epidermal architecture and is mediated by the opposing activities of LGN and its enigmatic paralog AGS3.

    Structural screens identify candidate human homologs of insect chemoreceptors and cryptic Drosophila gustatory receptor-like proteins

    Richard Benton, Nathaniel J Himmel
    A new screening strategy for divergent homologs of insect odorant and gustatory receptors, based upon predicted three-dimensional structural similarity, unexpectedly identifies candidates in humans.

    Cryo-EM structures of mitochondrial respiratory complex I from Drosophila melanogaster

    Ahmed-Noor A Agip, Injae Chung ... Judy Hirst
    Structures of respiratory complex I from the insect and metazoan model system Drosophila melanogaster reveal its close relationships with the mammalian complex and provide a foundation for new approaches to disentangle mechanisms of complex I catalysis and regulation.

    Peripheral and central employment of acid-sensing ion channels during early bilaterian evolution

    Josep Martí-Solans, Aina Børve ... Timothy Lynagh
    Expression patterns and biophysical properties of acid-sensing ion channels in numerous bilaterian animals offer insight into the deployment of ion channels by the evolving nervous system in complex animals.
