    Patterns of call communication between group-housed zebra finches change during the breeding cycle

    Lisa F Gill et al.
    Call-based vocal communication of individually recorded zebra finches changes in social groups across reproductive stages and is related with successful egg laying.

    3D in situ imaging of the female reproductive tract reveals molecular signatures of fertilizing spermatozoa in mice

    Lukas Ded et al.
    Fertilizing mouse spermatozoa, characterized by intact CatSper channels, lack of protein tyrosine phosphorylation, and reacted acrosomes, in the female reproductive tract provide molecular insight into sperm selection for successful fertilization.

    Knockdown of hypothalamic RFRP3 prevents chronic stress-induced infertility and embryo resorption

    Anna C Geraghty et al.
    A chronic stressor prior to mating has lasting negative consequences on the fertility and fecundity of female rats, which can be prevented by blocking a single hypothalamic reproductive inhibitory hormone.

    Trade-off shapes diversity in eco-evolutionary dynamics

    Farnoush Farahpour et al.
    In a minimalistic, generic model of competitive communities in which evolution is constrained by life-history trade-offs, stable biodiversity emerges with species adapted to different functional niches.

    Sexual selection gradients change over time in a simultaneous hermaphrodite

    Jeroen NA Hoffer et al.
    The quantification of sexual selection reveals that it is important to consider the chosen time frame of measurement as well as the sexual system.

    Migration confers winter survival benefits in a partially migratory songbird

    Daniel Zúñiga et al.
    Testing of fitness-related benefits in migratory population of European blackbirds offers confirming predictions of theoretical models on the evolution and maintenance of migration.

    A single mutation in Crimean-Congo hemorrhagic fever virus discovered in ticks impairs infectivity in human cells

    Brian L Hua et al.
    Tick-derived sequence variation in the fusion glycoprotein of Crimean-Congo hemorrhagic fever virus (CCHFV) drastically impairs infection of mammalian cells, suggesting that certain CCHFV strains undergo purifying selection in mammalian hosts.

    Odd-paired is a pioneer-like factor that coordinates with Zelda to control gene expression in embryos

    Theodora Koromila et al.
    The gene Odd-paired is a late-acting regulator of zygotic gene expression, functioning coordinately with Zelda to influence chromatin accessibility and affecting genes expressed along both axes of Drosophila embryos.

    A de novo evolved gene in the house mouse regulates female pregnancy cycles

    Chen Xie et al.
    A female specifically expressed new protein-coding gene that has emerged out of non-coding sequences without detectable signatures of adaptive evolution affects female pregnancy cycles.

    HSV-1 single-cell analysis reveals the activation of anti-viral and developmental programs in distinct sub-populations

    Nir Drayman et al.
    Single-cell analyses of cells infected by Herpes Simplex Virus 1 revealed extreme heterogeneity among infected cells, including the robust activation of developmental gene programs in highly infected cells.
