I’m currently writing my PhD thesis in Catalan —and some percentage in English to get the international mention— when they reveal that the actor who will take the lead role in Doctor Who will be, in fact, an actress. Weirdly enough, both facts are closely related.
If you saw the teaser of my first scientific musical two years ago, you know that pyrethroids are pesticides, that they are less toxic than DDT, organophosphorates and carbamates and that they are used in aquaculture —and that I’m not a professional singer. However, as you never saw the whole show, this video has a Shakespearean feel, much ado about nothing. So today I’m introducing these pesticides that you have been eating all your life and have probably applied to your hair unknowingly.
About a century ago pyrethrins, which were extracted from a plant of the chrysanthemum family, were modified to study how their chemical activity changed. Pyrethroids were created. In the seventies, pyrethroids went from household products to agricultural pesticides and started substituting other pesticides. Pyrethroids were more effective, stable but biodegradable and selectively more toxic to insects than mammals.
But pyrethroids are not only used on the crops. They are used to fight parasites in farms and fish farms, to treat lice or scabies and to control malaria, which is transmitted by mosquitoes. Now go check your home insecticide; it’s bound to have pyrethroids in it.
So why are language and Doctor Who in this article’s title? As I’m writing my thesis in Catalan, I’ve realised my mother tongue does something weird, unusual and against terminology’s best practices. In Catalan pyrethroids are transgender —not to be confused with transgenic. So the English permethrin in an agricultural context will be a male word (permetrín), while in a farmaceutical context it will be female (permetrina). English has feet that smell and noses that run; we’re entitled to our own excentricities. However, only pyrethroids that in English end in -in are transgender, others, e.g. fenvalerate, don’t change.
It bugs me [bugs and pesticides; see what I did there?] that when I talk about the compounds as molecules or when I discuss different applications in my thesis there will be no or both contexts involved. And you can’t go changing pesticides’ gender every other paragraph. It bugs me square that, maybe influenced by Spanish, which makes them always female, in my laboratory we’ve always used them in female form in Catalan. I might have to go back and amend some texts.
Which brings us to Doctor Who and the recent announcement of the new Doctor. After 54 years and 13* male incarnations, Doctor becomes her. Sadly enough, myriads of haters (both men and women) find it outrageous that a 2000-year-old alien who changes his body periodically is going to include his genitals in the next change. On the other hand, we’ve never been told what’s down there so, who knows?
Long story short, I write a blog to look modern and fashionable and there’s nothing more modern and fashionable than respecting the gender change of any person, character or pesticide.
* Disclaimer for trolls die-hard fans: I am obviously counting the War Doctor, but not the Metacrisis Doctor as that is a deviation that doesn’t lead to the current incarnation.
