- "Oxytocin varies across the life course in a sex-specific way in a human subsistence population". - And: old ♂ ♂ , have high level of oxytocin ! 😉 😏 😝. (Higher oxytocin is linked to good self-rated health, but this did not explain the rise in oxytocin in later life) www.pnas.org/doi/10.1073/...

So many " Natural phenomenons" go unnoticed by us, that inventing implausible Myths or invisible beings ( follow my gaze ) is waste our time. www.science.org/content/arti...

In the #gonad, #sex is not an irrevocable commitment, and requires active maintenance. Artyom Kopp explores a new @plosbiology.org study elucidating the molecular mechanisms that preserve sexual identity in the adult #Drosophila #testis 🧪 Paper: plos.io/4pMT6hq Primer: plos.io/3MRBBxG
