you can put the researchers names into a search engine (ask an academic librarian if you need help). I'm not sure if it's in the scope of the press release to link directly to primary sources.
To give you a better understanding of how this works, if my university didn’t include a link to my research in the press release about my publication, I’d contact them to issue a correction. That’s how fundamental it is to link to the research article.
this is a blog, not a rigorous publication with citations or formality.
That's a misunderstanding. This is not a "blog"; this is a press release from a university on its newsfeed. Linking to their own researcher's work is not a matter of being "rigorous" and is unrelated (and not at all similar) to academic citations.
