"The Conversation" is a Canadian newsletter and website that provides daily articles written by researchers on a number of topical themes.  Its tagline is "Academic Rigour, Journalistic Flair" and it prides itself on presenting academic research in a very reader-friendly style for the general public.   It is both a source of professional reading, and also research articles for an advanced or EAP class.  It includes the following sections: Arts, Business+Economy, Culture+Society, Education, Environment+Energy, Health, Politics, and Science+Tech.  The Education section is particularly relevant.  A key word search (learning English, English language etc.) in the search bar will return a significant number of articles of great interest including  this one which provides sound tracks of various non-native speakers with accompanying rankings (how difficult to understand they are) by ESL teachers.
