My memory was that this was an NPR story, the local affiliate has distinct production values that I believe I would have noticed. However, even searching the local affiliate's site only yielded the stories you referenced.

My only other suggestion is that stories often get shopped around and carried by multiple outlets. If you're anything like me, "the past year" might actually be the past five years, or more. There's often a study, book, institute, or specific investigator/doctor behind the story. If you really want to track down the story you might try broadening your search on those dimensions. (Or others which come to mind.)
Good luck!
