Popular newspaper and magazine articles are typically written by journalists to entertain or inform a general audience. A journalist may read an article from the scholarly literature and break it down for a non-expert audience (like climate research or medical findings)
Scholarly articles are written by (and for) researchers or experts in a particular field. They use specialized vocabulary, have extensive citations, and are often peer-reviewed.
