Lots of things we know about human physiology comes from animal studies.
Mice are not just some random animal species. They are a model organism for humans, meaning that they are sufficiently close in many ways such that insights are transferable.
2. Mice are obviously a useful first test subject or they wouldn't be used; they are also different enough from humans for studies to have no guarantee of results transitioning either smoothly or at all to us.
So yes, let's be more responsible with our link titles if the original articles "forget" to include the limitations.
Of course there is no guarantee. There never is in biology. Even if your study involves humans, there is bo guarantee that things apply to you or another cohort or are even reproducible. It's one data point and knowledge is built by gathering many of those which eventually paints a clearer picture.
