In particular here - this is very real work, published in a very good journal (if brand new (One of the very few excellent Open Access Journals)). In regards to your question about how to get a gut feeling - it's not easy. Reputation is still important in the scientific community - reputation of the university/department, of the lead authors, and of the co-authors, and the journal itself. If they're names you recognize, it's not to say that it will automatically be trustworthy- but the likelihood is much greater. Reading the abstract of the actual paper, and seeing how well it comports with the article is another good measure. Oftentimes the abstract will be in significantly less flowery terms, as there are so very very few scientific papers that are flat out, very-first, discoveries. All come from their predecessors, and come with caveats. Finally - science is slow (compared to news cycles). So best bet is to just wait, ask around, and talk with people who have an interest in the field.
