He was at Harvard Med and then Boston University, and published work on other cell types from the lung, but the cilia work was the highlight. There are 64 figures in that JCS paper! It's not clear who made the amazing illustration that we all use - nobody is credited in the paper, so perhaps him.

Looks like a suctorian. Which have very interesting microtubule structures, by the way. en.wikipedia.org/wiki/Suctoria

The genomic DNA was sheared by their prep, before the density gradient. The pieces were small enough that they were either fully replicated or unreplicated. If it was the whole genome, the experiment gives the wrong answer because the genomes are replicating asynchronously and relatively slowly..

I was young, and Stahl already seemed to me an old man who had done something famous long ago. Really, he was only in his mid-50’s and Meselson-Stahl was 30 years before. I regret not asking him more about it then, and the famous necessary artifact that allowed them to get the right answer.

It was, but I don't think the Senate version of that part of the bill is out yet.

It could. I haven't seen that part of the reconciliation bill yet, but should be out soon.
