Thwarted once, but not twice!

So PNAS didn't want my "all the animals" cover image, but the Journal of Histochemistry and Cytochemistry wanted one of my "BrdU artifact" images for their cover. Thanks, JHC editors, for making the right choice. Also exciting: the article is open access so everyone can read it!  Don't you want to? Wait, what, you don't?!?!  I am shocked.

(But is it space or brain?).
