    Direct glia-to-neuron transdifferentiation gives rise to a pair of male-specific neurons that ensure nimble male mating

    Laura Molina-García et al.
    A novel developmental mechanism generates a previously undescribed pair of sex-specific proprioceptive neurons required for male-specific behaviour.

    Drosophila seminal sex peptide associates with rival as well as own sperm, providing SP function in polyandrous females

    Snigdha Misra, Mariana F Wolfner
    A seminal protein from a mating-male can bind sperm previously stored in his mate, providing direct benefits to the sperm from the prior male that mated with her.

    Neuroanatomy of a hydrothermal vent shrimp provides insights into the evolution of crustacean integrative brain centers

    Julia Machon et al.
    A neuroanatomical analysis of Rimicaris exoculata provides insights into these animal’s brain architecture to illustrate possible adaptations to the hydrothermal vent habitat with its extreme physicochemical conditions.

    Seminal fluid compromises visual perception in honeybee queens reducing their survival during additional mating flights

    Joanito Liberti et al.
    After insemination, honeybee queens experience a rapid reduction in vision and flight performance, consistent with an ongoing sexual conflict over the number of mating flights that queens embark on.

    Investigation of Drosophila fruitless neurons that express Dpr/DIP cell adhesion molecules

    Savannah G Brovero et al.
    Analyses of fru P1 neurons that express dpr/DIP genes reveal roles for subsets of neurons in courtship, and the roles of Dpr/DIPs and the sex hierarchy in neuroanatomical sexual dimorphism.

    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.

    Adaptive thermal plasticity enhances sperm and egg performance in a model insect

    Ramakrishnan Vasudeva et al.
    Sperm and egg development are temperature sensitive, enabling males and females to significantly improve their reproductive success by matching gamete function to varying thermal environments for fertilisation and offspring development.

    Semen amyloids participate in spermatozoa selection and clearance

    Nadia R Roan et al.
    Ex vivo characterization of the interaction of human sperm with semen factors reveals that semen amyloids, previously discovered due to their ability to enhance HIV infection, serve a physiological function by promoting disposal of the defective sperm.

    Oviductal estrogen receptor α signaling prevents protease-mediated embryo death

    Wipawee Winuthayanon et al.
    Cyclic estrogen signaling in oviduct epithelial cells suppresses oviduct luminal protease activity to allow survival and development of preimplantation embryos

    Experimental investigation of ant traffic under crowded conditions

    Laure-Anne Poissonnier et al.
    Behavioral experiments reveal that ants, contrary to humans, avoid the formation of traffic jams at extreme density.
