I'm pretty desensitized to stuff, but this study is a horrifying. They basically mutiliated a rat by connecting it to another rat's circulatory system, implanted a uterus and then impregnanted it. It feels like this has crossed some boundaries of ethics. It's like that Russian experiment that decapitated a dog, connected it so that blood was recirculating through its brain, and then let it wake up. It's horrifying to think we can allow this in the name of science.
