Two things really stood out in this article. One is how brutal animal experimentation can be. The other is the opening line.

I read a lot of medical research papers, and I've been thinking about this recently. Every time I read about a rat being "euthanized" or "sacrificed", when they have neuropathy induced by toxins, when they have limbs amputated, when they have their spine severed... I can't help but pause for a moment and think about that animal.

I wonder if there are any good estimates of how many rats, rabbits, dogs and otherwise are maimed and killed each year for medical (or cosmetic) research. Is there, realistically, anything that would change this?

In one group of 11 mice, four had their intestines scrubbed to thin the mucosal lining and improve oxygen absorption. Next, the researchers injected pure, pressurized oxygen into the rectums of the scrubbed mice and four of the seven unscrubbed ones.

I don't even want to know how they do this and whose terrible job this is.

> It is estimated that the annual use of vertebrate animals—from zebrafish to non-human primates—ranges from tens to more than 100 million.[2] In the European Union, vertebrate species represent 93% of animals used in research, and 11.5 million animals were used there in 2011. By one estimate the number of mice and rats used in the United States alone in 2001 was 80 million.[3] Mice, rats, fish, amphibians and reptiles together account for over 85% of research animals.[4]

Yea... poor mice.. hopefully they weren't awake.

So this explains how my scrum master was able to speak about the Agile Manifesto without taking a breath.

Well no because to breath the intestines would need air and not be full of $4|7 ;-)

When can we reasonably expect the “cyclist gets banned from tour de france after committee finds athlete installed enteric oxygenation device in the saddle” headline?

Just wait until genetic modification becomes available on the black market. Then things will get really interesting.

If you think that is brutal you didn't see anything in animal experimentation.

I have a hunch future generations will look back on our animal experimentation similar to how we look back on human experimentation, horrified but with a silver lining (and most people just prefer not to think about it much at all). I'm very much against both, but I recognize the important advances they've made for medicine. I also recognize that most of the advances for animals don't translate to humans, and some even argue it's slowing progress overall.
