Excited to share work led by my PhD student Hayley McMorrow now published in @jclinical-invest.bsky.social. Hayley showed that GIP and GLP-1 receptor agonists rapidly inhibit AgRP neurons and that endogenous GIP is important for nutrient-mediated AgRP neuron inhibition. doi.org/10.1172/JCI1...

I've found rotary joints unusable for photometry, we've tried a few types (doric, Thor) but they introduce a lot of artifacts when they rotate. So we don't use rotary joints, instead use long 3 meter cables and loop them up high so there's room for the fibers to twist up some without tangling.

I found Jimmy Carter's Environmental Program (fittingly?) in the dumpster in the alley behind my house. "The sight of earthrise was awesome. It was also sobering. From that moment we could no longer avoid understanding that all life must share this one small planet and its limited resources."

Pamphlet of the President's Environmental Program 1979

Quote from Jimmy Carter: "Ten years ago, at the dawn of the environmental decade, we landed on the moon. For the first time people could stand on the surface of another world and look at the whole earth. The sight of earthrise was awesome. It was also sobering. From that moment we could no longer avoid understanding that all life must share this one small planet and its limited resources."

The fit line looks like poverty is rising robustly, but I'm not seeing that in the data points themselves. Maybe end the fit line at the min and max of the data instead of extending past it?

After 21 years at my dream job, I’m very sad to announce my early retirement from the National Institutes of Health. My life’s work has been to scientifically study how our food environment affects what we eat, and how what we eat affects our physiology.
