    Ovaries absent links dLsd1 to HP1a for local H3K4 demethylation required for heterochromatic gene silencing

    Fu Yang et al.
    A Drosophila fertility gene is identified that acts as a linker between HP1a and local H3K4 demethylation during HP1a-mediated gene silencing that is required for ovary development and transposon silencing..

    The Natural History of Model Organisms: Insights into mammalian biology from the wild house mouse Mus musculus

    Megan Phifer-Rixey, Michael W Nachman
    Studies of the house mouse Mus musculus have provided important insights into mammalian biology, and efforts to study wild house mice and to create new inbred strains from wild populations have the potential to increase its usefulness as a model system.

    Science Forum: Considerations when investigating lncRNA function in vivo

    Andrew R Bassett et al.
    We discuss the methods available to understand lncRNA function in vivo, and highlight important considerations that should be taken into account when designing such experiments.

    Thermoregulation: How a brain keeps its cool

    Swathi Yadlapalli, Orie T Shafer
    Temperature-sensing neurons in the Drosophila brain cooperate with the central circadian clock to help regulate body temperature.

    Species-specific modulation of food-search behavior by respiration and chemosensation in Drosophila larvae

    Daeyeon Kim et al.
    In naturalistic conditions, larvae of the Drosophila group exhibit species-specific strategies to search for food resources through a primitive form of risk-taking behavior that is controlled by a tradeoff between exploitation and odor-driven exploration.

    The C. elegans neural editome reveals an ADAR target mRNA required for proper chemotaxis

    Sarah N Deffit et al.
    Identification of tissue-specific RNA editing using a robust, publicly-available platform (SAILOR) reveals noncoding A-to-I editing events required for proper gene expression and neurological function, significantly advancing the understanding of how ADARs function in neural cells.

    O-GlcNAc on NOTCH1 EGF repeats regulates ligand-induced Notch signaling and vascular development in mammals

    Shogo Sawaguchi et al.
    The transfer of O-GlcNAc by EOGT to specific EGF repeats of NOTCH1 promotes DLL4 binding, Notch signaling, and retinal vascular development.

    Output variability across animals and levels in a motor system

    Angela Wenning et al.
    Population output variability in a motor control system varies across levels (CPG, motor neurons, muscles) and can be ascribed to life history differences among animals and in some cases to differences between bilaterally homologous elements.

    Convergence of topological domain boundaries, insulators, and polytene interbands revealed by high-resolution mapping of chromatin contacts in the early Drosophila melanogaster embryo

    Michael R Stadler et al.
    Fruit fly chromosomes are divided into discrete structural domains by regions of decompacted chromatin, suggesting a novel model for the formation of a known class of genetic elements.
