The content at the phys.org link was written by the University of New Mexico press shop (see my other comment).

And? HN deserves better... click on the DOI link at least and submit that, not this garbled secondhand trash.

My point is mostly that the problem is larger than phys.org. UNM itself is the source of the lesser article.

That phys.org just aggregates material available elsewhere is also an additional reason not to link it. It's suggested to link original articles (in a different sense than you are using) in the submission guidelines.

You’re certainly not wrong, and the endless parade of press releases and aggregators of press releases are indeed, terrible. Having said that however, I’ve never come across a site as popular and worthless as Phys.org (edit: in this space at least). The AAAS, iiie and other maintain decent aggregators, or the original is best.
