This is not right

“Human brain organoids implanted into rats could offer new way to model disease.” 

“Human brain organoids influence rat behavior.”

At nature.com, by way of 1440 daily digest.

“Clumps of human neurons implanted into brains of newborn rats have successfully integrated into the animals’ brain circuitry…”

Written presumably with a straight face and no irony: “The novel idea raised ethical questions, with the team consulting ethicists prior to experimentation on questions of animal welfare…”

Oh, my goodness. The ethical question of those poor rats being influenced by human organoids. No question of ethics in the whole procedure. Protect rats. The “scientists” did not mention the sources of the human brains used in the study.

Just because a thing can be done does not mean it should be done.
