    Immune genes are hotspots of shared positive selection across birds and mammals

    Allison J Shultz, Timothy B Sackton
    Pathogens, particularly viruses, target the same genes over deep evolutionary time, resulting in shared signatures of positive selection and transcriptional responses at the same genes.

    Comparisons between the ON- and OFF-edge motion pathways in the Drosophila brain

    Kazunori Shinomiya et al.
    A complete connectome of the ON and OFF motion pathways of the Drosophila optic lobe is acquired using three-dimensional EM methods, and the similarities and differences of the two pathways are uncovered.

    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..

    Meiotic drive of female-inherited supernumerary chromosomes in a pathogenic fungus

    Michael Habig et al.
    Female-inherited supernumerary chromosomes that lack a male-inherited homolog are transmitted to all meiotic products instead of the expected half, which indicates an additional amplification of unpaired chromosomes during meiosis.

    A re-inducible gap gene cascade patterns the anterior–posterior axis of insects in a threshold-free fashion

    Alena Boos et al.
    The body axis of insects is divided into different fates using a self-regulatory and threshold-free mechanism.

    Spatiotemporally controlled genetic perturbation for efficient large-scale studies of cell non-autonomous effects

    Andrea Chai et al.
    A novel genetic strategy for induction of reproducible neural tumors (or any other deleterious phenotype) in a single Drosophila stock (applicable to other organisms).

    Time-resolved mapping of genetic interactions to model rewiring of signaling pathways

    Florian Heigwer et al.
    Genetic interaction analysis by combinatorial genetic perturbation and high-throughput imaging maps time- and context-dependent crosstalk between signaling pathways.

    Reactive oxygen species regulate activity-dependent neuronal plasticity in Drosophila

    Matthew CW Oswald et al.
    Reactive oxygen species, previously considered damaging agents linked to pathology, are required for normal neuronal plasticity, including adjustment of synaptic terminal size, maintenance of synaptic physiology and adaptive behavioural responses.
