All good. Of course my descriptive headline was intended to emphasize the findings of the study. The journal article title simply offers that research has taken place -- and thus, is not nearly as useful. It would have been possible to link to a news article that interpreted the study (and had a 'catchy' title), but I thought HN readers would prefer a primary source. Regards!

example catchy title: 'Oral-B Glide floss tied to potentially toxic PFAS chemicals, study suggests' https://www.usatoday.com/story/news/nation/2019/01/09/oral-b...

Your "more descriptive" headline was misleading; floss was only one of four itemized factors, the more important of which was coatings on food containers.
