On Saturday I posted about a new study investigating whether morning or evening exercise is better (in what sense? they don’t say) for us. Spoiler: it doesn’t matter, at least as far as they know.
The investigators did their study using mice– male mice in particular. This did not go unnoticed by me, and certainly was noted plenty in the comments section.
Some made inquiries about where the female mice might be, along with plausible explanations:
Someone suggested they (the female mice) were tied up with other duties.
There were commenters who tried to defend the use of male-only mouse subjects on grounds of it-being-too-hard-to-do-science-on-female-organisms. Yeah, we’ve heard that before.
You didn’t think I was going to let that one get by me, did you?
Another attempted defense of the men-mice-only research plan came from this comment:
There’s a lot here, but let me just say that the mice could be held in separate cages, which would provide a low-tech solution. Am I missing something here?
In response to the male-mice-only defenders, someone suggested maybe doing more and better science might solve the air of mystery surrounding the ovulation cycles of female mice.
And I’m sure this person was trying to help, but…
Finally, someone got to the heart of the matter, pointing out what scientifically aware readers want to know:
Readers, what do you think? Do you personally know any female mice who’ve been turned down for science experiments? Have you metabolized cheese after-hours or only during daylight? Is ovulation too mind-blowing even to think about, much less study in a scientific fashion? I’m hoping that future comments sections will enlighten me as much as this one opened up a host of new questions…
