> I see that while I was reading the fine article from Nature submitted to open a thread, my comment is now part of a thread that is about the New Scientist popular article on the same research finding. This will be confusing to readers newly visiting this thread.

Incidentally, changing the source article after active discussion -- and especially to a secondary source when the original link is to the primary source -- is a really bad idea, even given the understandable and justifiable preference for non-paywalled sources.
