    Sex differences in learning from exploration

    Cathy S Chen, Evan Knep ... Nicola M Grissom
    A new computational analysis of decision making in mice shows sex biases in value-updating while exploring unknown options, with male mice tending to explore longer than females due to updating values more slowly.

    Deep proteome profiling reveals signatures of age and sex differences in paw skin and sciatic nerve of naïve mice

    Feng Xian, Julia Regina Sondermann ... Manuela Schmidt
    Proteomics uncovers thus far unknown age and sex differences in sciatic nerve and skin of naïve mice, highlighting the importance of adequate age matching and parallel investigation of male and female mice in biomedical studies.

    Comparative neuroimaging of sex differences in human and mouse brain anatomy

    Elisa Guma, Antoine Beauchamp ... Jason P Lerch
    Comparative neuroimaging quantifies the congruence of regional neuroanatomical sex differences between humans and mice.

    Reporting and misreporting of sex differences in the biological sciences

    Yesenia Garcia-Sifuentes, Donna L Maney
    A review of studies in the life sciences shows that inappropriate statistical approaches may distort conclusions on sex differences.

    Contrasting parental roles shape sex differences in poison frog space use but not navigational performance

    Andrius Pašukonis, Shirley Jennifer Serrano-Rojas ... Lauren A O'Connell
    Extensive field studies in poison frogs reveal that sex and species differences in parental behavior drive differences in space use patterns but not navigational performance and highlight the interplay between androgen levels and poison frog spatial behavior.

    Tradeoffs explain scaling, sex differences, and seasonal oscillations in the remarkable weapons of snapping shrimp (Alpheus spp.)

    Jason P Dinh, SN Patek
    Observational field analyses demonstrate that within a species, variation in animal weapon size corresponds to individual differences in the costs and benefits of weaponry.

    Testicular hormones mediate robust sex differences in impulsive choice in rats

    Caesar M Hernandez, Caitlin Orsini ... Jennifer L Bizon
    Sex differences in impulsive decision making, such that males are less impulsive than females, are critically dependent upon testicular but not ovarian hormones.

    Female-biased upregulation of insulin pathway activity mediates the sex difference in Drosophila body size plasticity

    Jason W Millington, George P Brownrigg ... Elizabeth J Rideout
    The ability to adjust body size in response to diet is greater in Drosophila females than males because of a sex difference in the nutrient-dependent regulation of the insulin pathway.
  1. Science Forum: Sex differences and sex bias in human circadian and sleep physiology research

    Manuel Spitschan, Nayantara Santhi ... Rhiannon White
    Research on human sleep and circadian physiology exhibits a bias towards male subjects, creating a sex data gap which holds potential real-world impact and requires concerted effort to close.

    Sex difference in pathology of the ageing gut mediates the greater response of female lifespan to dietary restriction

    Jennifer C Regan, Mobina Khericha ... Linda Partridge
    In the fruit fly Drosophila melanogaster, stem cell activity ages female guts but not male guts; furthermore, males with feminized guts develop pathologies but gain an increase in lifespan through dietary restriction.
