Another freelance science mouse

A few months ago, my labmates who study chipmunks enlisted the help of one of my pet mice to test-run a chipmunk-monitoring device that they are hoping to use in the field this summer. That went well, and now they’re calling on another one of my mice for a simpler test: to see how long the glue they’re planning to use will keep their device attached to rodent fur. They want glue that will stay attached long enough for them to get good data, but not so long that the monitor becomes a permanent part of a chipmunk’s life.

Since chipmunks spend a lot of time in burrows, we chose my most burrow-loving mouse, who likes to spend all of his time hiding underneath things. He was not pleased to be forced out into the open.

So far he hasn’t seemed to care a bit about the chip. However, he is quite annoyed that I now dig him up daily to check whether it is still attached. He’s not really a people mouse.

PLEASE just leave me alone.

Much better.

Adventure of a freelance science mouse

Two of my labmates study chipmunks. Recently they have been working with an engineer to develop a small tag that they can attach to a chipmunk to record the chipmunk’s movements. This, if it works, will let them “see” what the chipmunk is doing without actually watching–and bothering–the chipmunk, which would be great: one of the difficulties of behavioral ecology is that, for animals as for subatomic particles, observing the thing often affects the very nature of that thing.

Part of developing this tag is being able to check how well it works. Unfortunately, our lab doesn’t have any chipmunks just hanging around on which to test the tag. So instead, for an unofficial, exploratory test run, we recruited one of my domestic mice.

Think like a scientist: sample size

Science is not just for scientists. The methods of thought that underlie science are useful in all sorts of everyday contexts. Most obviously, everyone needs to be able to think like a scientist in order to interpret scientific results—you know, those newspaper headlines like “PAPER CLIP USE MAY LOWER IQ IN PREGNANT WOMEN!!” In that spirit, I’m going to write about some key concepts for thinking like a scientist. Today: sample size.

Pop quiz! You read this (totally made up) report: “Two groups of ten age- and health-matched men were monitored for heart disease. One group was given pet ferrets, while the other was not. The ferret-owning men were 8% less likely to develop heart disease over a five year period.” So: is it time to run out and get a ferret for the sake of your heart health?

You should get a ferret regardless, because ferrets are wonderful. This is my awesome old ferret Zap.
