Interesting article! A bit weird that they felt the need to plug the ugliest vehicle ever created, but the findings are certainly interesting! It's hard not to read enthusiasm into that little rat scooting along in its rat car!
It's disheartening to think that at the end of the experiment they'll just kill the poor thing, though. Like, I get not wanting to use the same rats from study to study so that you have a proper control, but there has to be a less heartless way of doing that.
