    Nitric oxide radicals are emitted by wasp eggs to kill mold fungi

    Erhard Strohm et al.
    To protect their food and themselves against detrimental mould fungi, the eggs of a wasp species synthesize and emit remarkable amounts of gaseous nitrogen oxides that are highly effective antimicrobials.

    An insect-like mushroom body in a crustacean brain

    Gabriella Hannah Wolff et al.
    An insect-like mushroom body in one group of crustaceans, the mantis shrimps (Stomatopoda), suggests either an ancient origin of this center and its reduction and loss in other crustaceans, or an extraordinary example of convergent evolution with the insect mushroom body.

    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.

    A gene horizontally transferred from bacteria protects arthropods from host plant cyanide poisoning

    Nicky Wybouw et al.
    The enzyme that allows some mites and insects to detoxify the hydrogen cyanide produced by plants has been identified.

    Evolution of thorax architecture in ant castes highlights trade-off between flight and ground behaviors

    Roberto A Keller et al.
    Body shape and behavioural specializations found across the castes of ant species evolved together and reflect different abilities for ground behaviors.

    Dynamic BMP signaling polarized by Toll patterns the dorsoventral axis in a hemimetabolous insect

    Lena Sachs et al.
    During the evolution of insect lineages, a signaling pathway dedicated to pathogen defense was co-opted for a new role in embryonic patterning.

    Hemimetabolous insects elucidate the origin of sexual development via alternative splicing

    Judith Wexler et al.
    Sexual differentiation controlled by sex-specific mRNA splicing evolved in a step-wise manner in insects.

    Evolutionary emergence of Hairless as a novel component of the Notch signaling pathway

    Steven W Miller et al.
    Hairless emerged as an evolutionarily novel regulatory protein that replaced an ancestral paradigm of direct co-repressor recruitment by Suppressor of Hairless, its partner transcription factor in the Notch signaling pathway.

    ketu mutant mice uncover an essential meiotic function for the ancient RNA helicase YTHDC2

    Devanshi Jain et al.
    The mouse gene Ythdc2 exemplifies an evolutionarily ancient family of crucial regulators of the transition from germline stem cell divisions to meiosis.

    Destructive disinfection of infected brood prevents systemic disease spread in ant colonies

    Christopher D Pull et al.
    Upon detecting a fatal infection using chemical cues, ants puncture the cuticle of sick brood and inject antimicrobial poison that disrupts the pathogen's life cycle and prevents it from reproducing, thus protecting the colony from disease.
