    Cystic proliferation of germline stem cells is necessary to reproductive success and normal mating behavior in medaka

    Luisa F Arias Padilla et al.
    In medaka fish, the reduction of cystic proliferation of germ stem cells declines gametogenesis, reproduction success, and male sexual behavior, with a decrease of mating vigor.

    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.

    Resistome diversity in cattle and the environment decreases during beef production

    Noelle R Noyes et al.
    Interventions in feedlots and abattoirs place selective pressure on the beef cattle resistome, which differentially impacts the public health risk of antimicrobial resistance from beef production sources.

    A viral protein promotes host SAMS1 activity and ethylene production for the benefit of virus infection

    Shanshan Zhao et al.
    Rice dwarf virus Pns11 protein increases rice susceptibility to virus infection by enhancing OsSAMS1 enzymatic activity and ethylene production.

    CD163 and pAPN double-knockout pigs are resistant to PRRSV and TGEV and exhibit decreased susceptibility to PDCoV while maintaining normal production performance

    Kui Xu et al.
    The double-gene-knockout pig is a valuable model to help understand the mechanisms of CD163 and pAPN in the infection of multiple viruses and offers excellent breeding materials for disease-resistant pigs.

    Loss of flavin adenine dinucleotide (FAD) impairs sperm function and male reproductive advantage in C. elegans

    Chia-An Yen et al.
    Loss of FAD stemming from cell autonomous defects in mitochondrial proline catabolism impairs sperm quality male reproductive advantage in C. elegans.

    Topological constraints in early multicellularity favor reproductive division of labor

    David Yanni et al.
    Mathematical modeling shows that reproductive specialization is strongly favored in sparse networks of cellular interactions that reflect the morphology of early multicellular organisms, even when benefits of specialization are saturating.

    Uniparental nuclear inheritance following bisexual mating in fungi

    Vikas Yadav et al.
    Discovery of a novel mode of sexual reproduction, termed pseudosexual reproduction, in fungi where both parents are required for mating but only one contributes to the meiotic progeny, similar to hybridogenesis in animals.

    Muscle-specific economy of force generation and efficiency of work production during human running

    Sebastian Bohm et al.
    During human running, the soleus muscle was found to operate as work generator under optimal conditions for work production (high force-length potential and enthalpy efficiency) while the vastus lateralis promoted tendon energy storage and economical force generation (high force-length-velocity potential).
