I just noticed that last Wednesday's piece on the movies of the dividing cells was my 700th proper post for Not Exactly Rocket Science! That includes opinion pieces, Not Exactly Pocket Science and the usual lengthy articles, but excludes reposts, photo posts or random missives. At the current pace, I'm averaging a respectable rate of around 100 posts every 5 months or so (the full list is here). I always like to mark these moments as little milestones for myself. But enough from me. Over to you. This is an open thread. Say or ask whatever you like.
