    Temporal transcriptional response to ethylene gas drives growth hormone cross-regulation in Arabidopsis

    Katherine Noelani Chang, Shan Zhong ... Joseph R Ecker
    The plant hormone ethylene regulates the expression of multiple genes in the model plant Arabidopsis, including those that respond to other hormones.

    Response to short-term deprivation of the human adult visual cortex measured with 7T BOLD

    Paola Binda, Jan W Kurzawski ... Maria Concetta Morrone
    Two hour deprivation of vision in one eye transiently boosts the representation of the deprived eye (suppressing the non-deprived eye) in adult human V1 and along the ventral pathway.

    Perinatal hormones favor CC17 group B Streptococcus intestinal translocation through M cells and hypervirulence in neonates

    Constantin Hays, Gérald Touak ... Asmaa Tazi
    Hormonal concentrations found in over 7-day-old neonates favor CC17 GBS invasiveness in a process linked to intestinal M cells maturation and mediated by the CC17 GBS surface protein Srr2.

    The embryonic role of juvenile hormone in the firebrat, Thermobia domestica, reveals its function before its involvement in metamorphosis

    James W Truman, Lynn M Riddiford ... Michelle Herko
    This sesquiterpene hormone likely acted as a morphogenesis-to-differentiation switch in archaic embryos before it evolved its postembryonic function as the status quo regulator of insect metamorphosis.

    A scalable and tunable platform for functional interrogation of peptide hormones in fish

    Eitan Moses, Roman Franek, Itamar Harel
    A novel in vivo strategy for reversible, multiplexed control of circulating hormone expression levels, achieved by combining genome-editing and intramuscular electroporation of fluorescently tagged hormones in the naturally short-lived turquoise killifish.

    Thyroid hormone regulates distinct paths to maturation in pigment cell lineages

    Lauren M Saunders, Abhishek K Mishra ... David M Parichy
    Single-cell transcriptomics combined with genetic analyses identify post-embryonic neural crest subpopulations and thyroid hormone dependencies in zebrafish adult pigment pattern development.

    Discovery of methylfarnesoate as the annelid brain hormone reveals an ancient role of sesquiterpenoids in reproduction

    Sven Schenk, Christian Krauditsch ... Florian Raible
    A small brain-derived lipid prevents bristle worms from entering maturation and death, challenging current views of hormone evolution and pesticide specificity.

    A resource for the Drosophila antennal lobe provided by the connectome of glomerulus VA1v

    Jane Anne Horne, Carlie Langille ... Ian A Meinertzhagen
    FIB-SEM is used to identify comprehensively and reconstruct 192 neurons and their complete connectome for glomerulus VA1v of the Drosophila antennal lobe, in particular to reconstruct its local interneurons.

    DAAM mediates the assembly of long-lived, treadmilling stress fibers in collectively migrating epithelial cells in Drosophila

    Kristin M Sherrard, Maureen Cetera, Sally Horne-Badovinac
    Stress fibers with multiple adhesions along their lengths and treadmilling dynamics may help migrating epithelial cells maintain a linear trajectory and thereby reinforce their collective motility.

    The innate immune sensor IFI16 recognizes foreign DNA in the nucleus by scanning along the duplex

    Sarah A Stratmann, Seamus R Morrone ... Jungsan Sohn
    The scanning-assisted clustering mechanism of IFI16 not only allows efficient assembly on exposed foreign-dsDNA, but also suppresses the engagement of chromatinized self-dsDNA.
