Here are the figures: http://www.nature.com/nature/journal/vaop/ncurrent/fig_tab/nature22067_ft.html http://www.nature.com/nature/journal/vaop/ncurrent/fig_tab/n... If you need a fulltext link that can be arranged, but it's not a bad idea to understand how DOIs work. Here is one: doi:10.1038/nature22067 This is essentially a URI; the piece after the : is a URN, which is meant to uniquely identify a piece of published research (now expanded to include preprints and software). To route it, you'll need a URL which your browser can resolve. Happily, if you visit http://dx.doi.org/10.1038/nature22067 http://dx.doi.org/10.1038/nature22067 you will return to the paper. It is meant to provide a durable identifier, so that even Elsevier journals can't reliably hide the identity of a publication. What this also means is that "unlocking" services like Elbakyan's can use it as a primary key. Suppose you paste the URN part of that DOI onto http://sci-hub.cc/ http://sci-hub.cc/ or http://sci-hub.bz/ http://sci-hub.bz/ to complete the URL. What do you suppose happens? (This is left as an exercise for the reader, and of course I cannot and do not condone violations of copyright law. So don't read whatever might pop up, ok?)
