    Genomic architecture and evolutionary antagonism drive allelic expression bias in the social supergene of red fire ants

    Carlos Martinez-Ruiz et al.
    Analyses of allelic- and socially-biased gene expression reveal that suppressed recombination causes most of the expression differences in the social supergene, with only few differences due to socially antagonistic selection.

    Drosophila seminal sex peptide associates with rival as well as own sperm, providing SP function in polyandrous females

    Snigdha Misra, Mariana F Wolfner
    A seminal protein from a mating-male can bind sperm previously stored in his mate, providing direct benefits to the sperm from the prior male that mated with her.

    Revealing the structure of information flows discriminates similar animal social behaviors

    Gabriele Valentini et al.
    Information theory reveals that apparently similar signaling behaviors in ants and termites are instead governed by distinct communication protocols explaining their underlying different functions.

    Isolation and transcriptomic analysis of Anopheles gambiae oenocytes enables the delineation of hydrocarbon biosynthesis

    Linda Grigoraki et al.
    Delineation of the cuticular hydrocarbon biosynthetic pathway in malaria vectors is a key step in understanding how mosquitoes adapt to anthropogenic change and vector control interventions.

    A moth odorant receptor highly expressed in the ovipositor is involved in detecting host-plant volatiles

    Rui-Ting Li et al.
    A moth can detect plant volatiles using an odorant receptor expressing in its ovipositor, and this odorant receptor has a much higher expression level in the ovipositor than antennae.

    Convergent evolution of small molecule pheromones in Pristionchus nematodes

    Chuanfu Dong et al.
    Unexpected structural diversity of nematode small molecules, as revealed by high-resolution phylogenetic analysis, suggests recurrent biochemical innovation, a pattern that is probably typical across animals.

    Sex-determining genes distinctly regulate courtship capability and target preference via sexually dimorphic neurons

    Kenichi Ishii et al.
    Sex-specific characteristics of the fruit fly courtship behavior are not specified by a single binary switch, but as a combination of traits that are modularly specified by separable genetic switches.

    A neuropeptide regulates fighting behavior in Drosophila melanogaster

    Fengming Wu et al.
    Dsk-expressing neurons function downstream of a subset of P1 neurons to control fighting behavior.

    An alternatively spliced, non-signaling insulin receptor modulates insulin sensitivity via insulin peptide sequestration in C. elegans

    Bryan A Martinez et al.
    A truncated, non-signaling insulin receptor regulates insulin sensitivity in the nematode C. elegans by sequestering insulin peptides and preventing their interaction with full length receptors.

    Reliability of an interneuron response depends on an integrated sensory state

    May Dobosiewicz et al.
    A pair of interneurons in C. elegans condenses information from multiple sensory neurons into a uniform response, using an AND-gate logic to represent a stimulus with positive valence.
