Not necessary IMO, I think co-authored publications are a fairly noisy signal early in one's career

When someone says „Scientists do not want you to know“ you can dismiss everything from there on. Scientists want you to know. They are desperate that you know. They can’t shut up about what they found out and want you to know.

Strange story! Hopefully you can walk the line and teach them about remixing permissions while also not inhibiting their interests in 3d design, printing, and even business! If possible I'd try communicating with their parents instead of the 10yo directly.

Yeah let's send the findings through their tool!

If it's the group from U Chicago I did it. It was fine, but none of the suggestions made sense as actual experiments to complete, and I responded as such. I can't seem to find the results in my email but they did not make enough of an impression on me to save them or think about them again.

JCI - Incretin receptor agonism rapidly inhibits AgRP neurons to suppress food intake in mice

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.

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."

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."

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.
