Side hustle level-up! My book, IN THE BEGINNING, will be published by @harperonebooks.bsky.social in 2027! It's about the human embryo, how it gets built, and what it means for where we come from and where we're going.

Gentle reminder that everyone should read Jacob and Monod, 1961. And then read it again every once in awhile. A master-class on clear writing (and, ya know, Nobel Prize winning stuff, too).

Stoked to have this perspective about my favorite organelle out in JCS! Give it a read, then let's argue!
In their Perspective, John Wallingford @jbwallingford.bsky.social and colleagues present their view on the assembly and potential function of DynAPs, as well as their place within the broader context of motile ciliated cells.

Everyone knows I suffer from Drosophila envy. I blame C.W. Woodworth. He studied the fly's embryos in W.E. Castle's lab; Castle would be the first to use them for genetics. The rest is history. Woodworth's gorgeous 1889 pictures of butterfly embryos are below. Enjoy! 1/3

Last chance to tell the NIH if you think animal models are important for biomedical research! 👇👇👇👇
The NIH is asking scientists and the public to comment on plans to drastically limit animal model research. If you think animal models remain important tools for basic and clinical research tell them! Click the link below and scroll down to send your comments!

Birth defects kill twice as many children as cancer. Animal model are crucial; no stem-cell or computer models can yet recapitulate the embryo's complexity. If you support birth defects research tell NIH that animal models are important! Click & scroll below to comment.
