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.

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.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
the purpose or at least at least a purpose of that activation is to cause you to learn about the effects of what you just ate basically to create this connection between the flavor of something and its post-ingestive effects so that sort of that that delayed dopamine signal uh after ingested food and fluids is sort of reinforcing this connection between the flavor of what I just ate and that it was something good for me
he showed there was this delayed dopamine response after the mice had drank the fluids uh uh that correlated with rehydration of the blood so a whole bunch of dopam neurons get strongly activated when the blood is rehydrated and he hypothesized this might be a signal this delayed this delayed activation of dopam neurons that allows animals in the wild to learn uh uh uh that food I just ate is is is rehydrating
