    Metazoan evolution of glutamate receptors reveals unreported phylogenetic groups and divergent lineage-specific events

    David Ramos-Vicente et al.
    The animal phylogeny of glutamate receptors indicates that vertebrate types do not account for all receptor classes originated during evolution, neither are they the pinnacle of a linear evolutive process.

    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.

    The RFamide receptor DMSR-1 regulates stress-induced sleep in C. elegans

    Michael J Iannacone et al.
    During sickness, sleep is induced by neuropeptides, which contain an amidated arginine-phenylalanine motif, acting in a neuroendocrine fashion on a G-protein coupled receptor called DMSR-1.

    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.

    Acquisition of exogenous haem is essential for tick reproduction

    Jan Perner et al.
    The lack of haem biosynthetic and degradative pathways in ticks offers new strategies to combat these parasites.

    Modelling the climatic suitability of Chagas disease vectors on a global scale

    Fanny E Eberhard et al.
    The global ensemble forecasting niche modelling of 11 vector competent triatomine species revealed climatic suitable regions outside their native distribution including the cosmopolitan vector Triatoma rubrofasciata.

    Punctuated evolution and transitional hybrid network in an ancestral cell cycle of fungi

    Edgar M Medina et al.
    Cell cycle network evolution in a fungal ancestor was punctuated by the arrival of a viral DNA-binding protein that was permanently incorporated into the regulatory network controlling cell cycle entry.

    The cation channel TRPA1 tunes mosquito thermotaxis to host temperatures

    Román A Corfas, Leslie B Vosshall
    Female mosquitoes are exquisitely sensitive to human body heat, and the TRPA1 gene is required to focus their attraction toward thermal stimuli resembling warm-blooded hosts.

    Recurrent loss of CenH3 is associated with independent transitions to holocentricity in insects

    Ines A Drinnenberg et al.
    CenH3, the defining component of centromeres in almost all eukaryotes, was independently lost in four insect lineages that transitioned from monocentricity to holocentricity.
