Why not suffocate them with nitrogen or co2 or something?
CO2 is common in labs though lab rats/mice do show aversion to CO2 which is interpreted to mean that it causes distress. So there's been ongoing debate for 20+ years over how humane CO2 is and what the correct flow rate should be and if oxygen should be added (or not) or other gasses (or not).[1]
Something physical like direct concussion/blunt force trauma followed up by another method might be better[2] (needs more studying) but there's also issues with physical methods because they require more skill to do correctly (or tools/machines developed to negate the skill factor).
Also operators dislike physical methods compared to gassing[1] so what's most practical might end up the standard[3] even if it may not be the most humane.
I mean, theoretically if you could instantly crush a mouse, faster than brain/nerve signals can travel, that would be humane, right? But then a human has to deal with a gruesome crushed mouse.

>and Europe's population Where are you getting this from? Loads of countries are still rising in population, mostly due to immigration (birthrates of natives are below replacement rates). >and they seem to be quite well off. I wouldn't call Europe 'well off', unless your definition solely relies on "well, at least it is a developed country". We're facing multiple crises in several countries, and the younger generatio…
> Europe's population The growth rate has certainly slowed in the last 30 years or so. From 0.98% in 1960 to 0.37% in 1990 and 0.12% in 2020. But, yes, it's still growing overall. https://www.worldometers.info/world-population/europe-popula...

My daughter got an internship at a research lab this summer - where they have thousands and thousands of research mice and they kill several mice every day. She said CO2 works on adults and therefore that's what they use. But CO2 doesn't work on baby mice and is considered inhumane. Instead they use scissors and cut off the baby mice's heads. It's to be done swiftly so it's like a guillotine. The labs are continually…
> Instead they use scissors and [swiftly]
oh snap!
Mice must have a high nervous conductance rate and as small as they are, what do you reckon how quickly it had to go through for there to be no impulse to speak of? (ask her!)

I don't get it. Are you angry that he performed those fear studies, or just that he made a joke about it in the presentation? If you see the importance of the results gained from the former, you should have no problem with the latter. Scientists need a way to cope with their emotions as well.
Re: Mouse Heaven or Mouse Hell?
#116It would seem like the more obvious lesson would be, "when in conditions very different from what that species evolved for, new and often serious problems will arise". Which is, no doubt, true and even relevant. But, since we evolved for conditions very different than rats did, I'm not sure how much more can be concluded. It does point out, though, the importance of being skeptical of any other scientific study done…
What was surprising is that the mice didn’t end up evolving some traits and instincts optimized for the new conditions. I would’ve thought they would learn new behavior after a few generations to thrive in the new environment. This makes me think that a post scarcity environment may not be enough to ensure the survival of a species

Why hot water? I would have thought cold or preferably lukewarm water would be more humane.

I'm not vegan but I think about it all the time.
Same boat. I'm not a vegan, and I try my absolute best to avoid thinking about what we put animals through. It certainly sits in a specific category of intrusive thoughts. The only real analog to this in my mind is being aware of my own mortality; I just avoid that thought and shove it out of my mind. Occasionally my comparatively relaxed life is harshly interrupted by an awareness of these facts and I'm ripped back…

A surgeon, while operating with all diligence and conscientiousness, may from time to time kill a patient. That's life, it's table stakes to having surgery at all. The notion that it's cool if she jokes about killing the patient to "cope with her emotions" -- esp in an auditorium full of people -- is just fucking ... I dunno what to tell you if you think that.
