This thread has probably run its course (and then some), but this is just so odd. It strikes me as a different way of thinking, perhaps stemming from a top-down authoritarian system in which Chinese leaders probably *can* make things disappear. The authors' own "retraction" statement:
"We, the authors, are retracting this Article to prevent inaccurate information from remaining in the literature..."
is nonsensical--it's *in* the literature at this point, especially if it has been published in hardcopy. All you can do now is publish corrections and such. Nor should Nature be altering the original PDF online. I wonder who reviewed the paper, if anyone.
