    Episode 30: June 2016

    In this episode we hear about drug production, early career researchers, honeybees, human migrations and pain.
    1. Genetics and Genomics

    Firefly genomes illuminate parallel origins of bioluminescence in beetles

    Timothy R Fallon et al.
    The first genomic view of beetle luciferase evolution indicates evolutionary independence of luciferase between fireflies and click-beetles, and provide valuable datasets which will accelerate the discovery of new biotechnological tools.

    The genome of the crustacean Parhyale hawaiensis, a model for animal development, regeneration, immunity and lignocellulose digestion

    Damian Kao et al.
    The first malacostracan genome sequence will establish the genetically tractable Parhyale hawaiensis as a model organism in this key animal group.

    2. Neuroscience

    Bumblebee visual allometry results in locally improved resolution and globally improved sensitivity

    Gavin J Taylor et al.
    Bigger bumblebee eyes have better vision, yet their field of view, sensitivity, and resolution do not all simply scale up with eye size, being improved locally instead.
    1. Evolutionary Biology

    Expansion of the fatty acyl reductase gene family shaped pheromone communication in Hymenoptera

    Michal Tupec et al.
    A fatty acyl reductase gene family expansion in the Hymenoptera crown group led to recruitment of novel pheromone-biosynthetic enzymes and is linked to evolution of pheromone marking behavior.

    In vivo targeting of de novo DNA methylation by histone modifications in yeast and mouse

    Marco Morselli et al.
    DNA methylation deposition is dependent on the presence of H3K4me3 and H3K36me3 histone marks.
    1. Evolutionary Biology

    Genes associated with ant social behavior show distinct transcriptional and evolutionary patterns

    Alexander S Mikheyev, Timothy A Linksvayer
    Genes associated with age-based division of labor in ants exist in distinct regulatory and evolutionary contexts; genes up-regulated in young nurses are loosely connected and rapidly evolving while genes up-regulated in old foragers are highly connected and conserved.
    1. Developmental Biology

    Folded gastrulation and T48 drive the evolution of coordinated mesoderm internalization in flies

    Silvia Urbansky et al.
    Functional recapitulation of a likely evolutionary gain in gene expression shows that two genes are sufficient to switch mesoderm cell internalization from stochastic cell ingression to coordinated epithelial invagination.
    1. Neuroscience

    The carcinine transporter CarT is required in Drosophila photoreceptor neurons to sustain histamine recycling

    Drew Stenesen et al.
    Fly vision depends on a member of the SLC22 transporter family for recycling the histamine neurotransmitter following its uptake by glia and its modification into the transport metabolite carcinine.

    Combined transcriptome and proteome profiling reveals specific molecular brain signatures for sex, maturation and circalunar clock phase

    Sven Schenk et al.
    A molecular profiling approach to quantify transcripts and proteins from identical samples allows study of molecular effects of maturation, sexual differentiation and the endogenous circalunar clock in a marine worm.
