    Altered paracrine signaling from the injured knee joint impairs postnatal long bone growth

    Alberto Roselló-Díez et al.
    Genetic analyses in mice reveal a communication system between the knee joint and the developing bones that could be explored in studies addressing evolutionary changes in body proportions and in future therapies for growth disorders.

    Transgenerational dynamics of rDNA copy number in Drosophila male germline stem cells

    Kevin L Lu et al.
    rDNA copy number is shown to dynamically change during aging and through generations, and is actively maintained in male germline of Drosophila.

    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.

    The Tudor SND1 protein is an m6A RNA reader essential for replication of Kaposi’s sarcoma-associated herpesvirus

    Belinda Baquero-Perez et al.
    SND1 has m6A-reading ability and is essential for Kaposi's sarcoma-associated lytic replication.

    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.

    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.

    The genome of an intranuclear parasite, Paramicrosporidium saccamoebae, reveals alternative adaptations to obligate intracellular parasitism

    C Alisha Quandt et al.
    Parasitic lineages of Rozellomycota are shaped by repeated and independent gene losses.

    Discovery of methylfarnesoate as the annelid brain hormone reveals an ancient role of sesquiterpenoids in reproduction

    Sven Schenk et al.
    A small brain-derived lipid prevents bristle worms from entering maturation and death, challenging current views of hormone evolution and pesticide specificity.

    Evolution of insect olfactory receptors

    Christine Missbach et al.
    Insect specific olfactory receptors are not an adaptation to a terrestrial insect lifestyle, but evolved later in insect evolution.
