We still consider it a dupe if it's about the same underlying topic, which it certainly is in this case.

Sometimes we'll update the URL to the canonical source (i.e., the study paper) if the submitted article is just a summary that adds no substance (aka blog spam). But if it's a report from a reputable publication that adds substance, we'll leave that as the URL and link to the study paper from the top text, which I've done now.
