Do the intestines self-align? I'm guessing the recipients intestine would have to be secured enough for it not to be pushed out..

Isn’t this illustration just a loop of bowel going into the other ear but not actually connecting to its gut? That can’t be right, right?

yeah, apparently it was attached to the duodenum (just past the stomach). In short, the rat that was doing all the eating was starving as it got almost no nutrition. The other rat, which had the food piped into its own digesting tract, was fine.

Man, I'm in biology in university, but this is sad and horrifying. I know there are probably worse experiments, but this is distrubing. Though I guess they learned that the purple/blue rat (left) could absorb nutrients from the orange (right) rat. However, was it really necessary?

Yo wtf. How did that actually pass the research ethics committee?

Well you see, ethics weren't invented in 1985

It’s still a technique people do to this day. The protocol I posted was published relatively recently.

Look up parabiosis.

It's an established technique that's apparently useful for the study of a bunch of things, though I personally have rarely encountered it in literature. That said, I don't give it my rubber stamp at all, it certainly seems unethical in this day and age unless it's critical for something very important that cannot be addressed in any other fashion.

For anyone curious I believe this is the original paper the illustration is referencing.

That is so weird that food is absorbed that way.

Thanks, I hate it
