Because this article isn’t a review of a single paper?

They’ve used a single paper to write a broader article. You can find other papers that justify the other claims that the article makes.

Being a popular article as opposed to an article in a scientific journal means references are not also necessary, although I suspect if you reached out to the author they would provide you with a list of references they used.

Also, the idea that the media used to be better is even more laughable. In fact, popular science media, with all its flaws, is better than its ever been. The reality is popular science is just hard to do.
