    Sex-specific triacylglycerides are widely conserved in Drosophila and mediate mating behavior

    Jacqueline SR Chin et al.
    Triacylglycerides found in the males of 11 species of Drosophila form a largely overlooked, novel, sex-specific class of pheromones that act to suppress courtship behaviour.

    Bacterial contribution to genesis of the novel germ line determinant oskar

    Leo Blondel et al.
    Evidence suggests that the oskar gene, a critical germ line determinant in insects, was formed by fusion of bacterial and eukaryotic sequences at least 450 million years ago.

    Cis-regulatory evolution integrated the Bric-à-brac transcription factors into a novel fruit fly gene regulatory network

    Maxwell J Roeske et al.
    The conserved biochemical activity of the duplicate Bab transcription factors were integrated into the regulatory hierarchy of an evolving gene regulatory network by binding site gains in a target gene's cis-regulatory region.

    Dopamine drives Drosophila sechellia adaptation to its toxic host

    Sofía Lavista-Llanos et al.
    The insect dopaminergic system serves an important function in the regulation of ontogenesis and early development, contributing to the evolutionary processes that limit the ecological niche of Drosophila sechellia.

    The life cycle of Drosophila orphan genes

    Nicola Palmieri et al.
    The short lifetime of orphan genes is a major factor explaining the stability of gene number in Drosophila.

    Olfactory channels associated with the Drosophila maxillary palp mediate short- and long-range attraction

    Hany KM Dweck et al.
    Drosophila's second nose, the maxillary palp, is involved in short- and long-range attraction.

    Stochastic variation in the initial phase of bacterial infection predicts the probability of survival in D. melanogaster

    David Duneau et al.
    An analysis of within-host bacterial proliferation reveals that minor "stochastic" variation in the ability of the innate immune response to control bacterial growth early on can result in either survival or death of the host.
