Thanks for that link!
I didn't find it in my search...
In the phys.org article:
> The paper is published in the journal Land.
the word 'published' links to the MDPI paper
It's good to know the link was in the phys.org article. I didn't read it.
When I have interest in an article at that site, I search for the text of the headline, and try to identify the original source.
