This source violates our acronym so it is SO TRASH. While it is published in a credible journal, a quick search for its credibility on Other sites, you'll find that this journal was retracted two days after its publication due to an error in production. Sometimes you'll see a story that was retracted but the statement is made after the headline so be sure to Read past the headline!
