So what makes this work differently than a GLP-1 agonist? everything hear sounds like this is another potential weight-loss drug by a well known mechanism

Yes! But only the big ones. Mayo Clinic is the only one I know of that got one in 2017

Reply to comment by CrustalTrudger in Extinction of the Dinosaurs: What did I miss? by cakedayCountdown
So you got me curious about multiple factors relating to the current and previous extinction events.
O-S was climate and atmospheric composition, greenhouse effect of volcanos, and loss of oxygen.
The Devonian event(s) were ecological, but I can't find much on it.
P-T was ocean acidification, oxygen loss, greenhouse caused by volcanism
T-J was again, acidification, climate changed, and oxygen loss.
K-G, again, acidification, climate change, but I can't find atmospheric composition.
Regardless, it appears that the extinctions occur once those worldwide changes start, regardless of the cause. What I'm curious about now is if there is any evidence at how inhospitable the planet was by the end of the extinction events.
