Scientific terminology

Via Dara Sosulski, highlighting a sentence from a scientific paper she was reading, “The ping-pong cycle acts independently of Piwi and Armitage but requires the function of Aubergine, the RNA helicases Spindle-E and Vasa, and the Tudor-domain protein Krimper.”

I, Editor, on the other hand, muses on the origins of the term "missing link", blacklisted from all reputable scientific discourse. All ancient suggestions welcome at the I, Editor post.

rENNISance woman asks: please define "other". Ye gods! Words fail me. (But do read the comments to her post.)
