Well then this "study" is just an observation. So it probably doesn't warrant the amount of attention it is getting, to say nothing of people using this "study" as evidence. Observation is an early step of the scientific method, but now they need to perform a scientific experiment in order to make this newsworthy. (Well I guess it is "newsworthy" in that it makes for high click-through...)
Yes. Many studies are.

It seems like you lack an understanding of how science works? Because the fact that this is an observation doesn't mean that it isn't evidence. Observation is like one of they key kinds of evidence.

No they don't. That's not how this works, at all. It's still valid meaningful evidence. I mean, do you ever read stories about stellar discoveries? Do you think they aren't worth reading because they didn't do an experiment to re-create the black hole they discovered in a lab?
