    Maternally inherited piRNAs direct transient heterochromatin formation at active transposons during early Drosophila embryogenesis

    Martin H Fabry et al.
    Maternally deposited Piwi-piRNA complexes co-transcriptionally repress transposable elements that transiently become active in somatic cells of the developing Drosophila embryo.

    Epi-mutations for spermatogenic defects by maternal exposure to di(2-ethylhexyl) phthalate

    Yukiko Tando et al.
    Gene analyses reveal the abnormal DNA methylation and expression of the genes essential for spermatogenesis as a cause of spermatogenic defects in offspring induced by maternal exposure of a chemical.

    Somatic aging pathways regulate reproductive plasticity in Caenorhabditis elegans

    Maria C Ow et al.
    Somatic aging and germline RNAi pathways promote inheritance of ancestral starvation memory through reallocation of fat storage in Caenorhabditis elegans.

    Evaluating distributional regression strategies for modelling self-reported sexual age-mixing

    Timothy M Wolock et al.
    Integrating the sinh-arcsinh distribution into a distributional regression framework allows us to produce precise, local estimates of sexual age-mixing, facilitating more accurate modelling of sexually transmitted disease dynamics.

    Selection for increased tibia length in mice alters skull shape through parallel changes in developmental mechanisms

    Colton M Unger et al.
    Artificial selection for increased tibia length in mice made their skulls longer, narrower, and flatter, suggesting that even distant skeletal regions can evolve as correlated responses to selection acting locally.

    High social status males experience accelerated epigenetic aging in wild baboons

    Jordan A Anderson et al.
    Among the factors that predict fitness in wild baboons, dominance rank in males, but not in females, is the best predictor of epigenetic aging.

    Paternal multigenerational exposure to an obesogenic diet drives epigenetic predisposition to metabolic diseases in mice

    Georges Raad et al.
    Predisposition to obesity-associated diseases is dependent on the ancestors' diet.

    Stress resets ancestral heritable small RNA responses

    Leah Houri-Zeevi et al.
    Various types of stress reset heritable small RNA responses through the function of the p38 MAPK pathway, the transcription factor SKN-1/Nrf2, and the MET-2/SETDB1 putative histone methyltransferase.

    Social groups buffer maternal loss in mountain gorillas

    Robin E Morrison et al.
    In mountain gorillas, as in certain human populations, relationships between group members can act as a social buffer, breaking the link between maternal loss, increased social adversity, and decreased fitness.

    Education and Outreach: March Mammal Madness and the power of narrative in science outreach

    Katie Hinde et al.
    Hypothetical battles between animals can be used to interest the general public in biology.
