Honestly, we expect better reporting from @bbcnews-world-rss.bsky.social. But this week, on #obesity, they failed us big time. @bmj.com didn't do much better. #Bias about obesity is hard to overcome. Implicit bias is the worst.

I read enough to say that this is very true.
One year, I counted the time it took me to write 4 proposals (3 as PI). If I recall correctly, it was 150-180 hours, about ~2.5 months which I got naught money out that effort (massacre year). And these were proposal that would fund me just ~0.25 FTE 1/n

The Montreal Protocol reduced loss of ozone and prevented large increases in UV-B radiation.
In the meantime, air pollution, wildfires, volcanic eruptions, and changes in surface reflectivity or solar activity may have reduced the UV-B radiation available to us.

Includes fascinating anecdotes of Holick's 1970s laboratory work and the fierce competition between the Kodicek, DeLuca, and Norman labs for finding the active form.
