The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
what they've done is they've given a probiotic to these mice normalize their social functioning — and that in there's an increase in oxytocin and in a recent study also vasopressin at the level of the hypothalamus so by giving a probiotic you I believe the oxytocin levels were increased in the blood you saw more species typical social behavior and this was all driven by this upregulation of oxytocin gene expression and also vasor pressent in this very recent study
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

um they're they're by increasing the diversity of gut microbiota because that's really what a probiotic does sort of across the board increases the diversity of gut microbiota no one specific ilis as I always say because they all seem to end in ilis you know multiple Iles Iles ilsy here we go again um you upregulate gene expression and thereby action of oxytocin and vasopressin in the hypothalamus but that's a neurom mediated thing it's not as if the microbiota travel to the brain something changes in the gut which activates the vagal pathway from gut to the specific nucleus in the brain and um we know that the vagal pathway is involved because it seems at least partially necessary if you sever that you give a vagotomy then the uh this effect is is blunted or eliminated
