This investigation of Ranga Dias' superconductivity publications is remarkable for multiple reasons.

Nobody comes out of it well, but Nature are much more transparent about the editorial process than I can ever remember. (It's a little unclear if that was spontaneous, but, if not, the frequently claimed independence of Nature News came good.)

Superconductivity scandal: the inside story of deception in a rising star’s physics lab

Ranga Dias claimed to have discovered the first room-temperature superconductors, but the work was later retracted. An investigation by Nature’s news team reveals new details about what happened — and how institutions missed red flags.

The "research" is at times risible. Key experimental results appeared suddenly in a manuscript version upon which lab members were given a couple of hours to comment before submission to Nature.

"When the students asked Dias about the stunning new data, they say, he told them he had taken all the resistance and magnetic-susceptibility data before coming to Rochester."

Just nonchalantly sitting on proof of room-temperature superconductivity for a few years, as one does. /2

The students are definitely not the villains of the piece, but if they "did not suspect misconduct at the time" and "trusted their adviser", they seem somewhat naive under the circumstances. /3

For the first paper, Nature engaged three referees and there were three rounds of review. One referee was strongly positive, the other two did not support publication. Nature went ahead anyway.

I can't think of a previous black on white example where Nature have admitted allowing impact to override quality, although that's always been the tacit implication of their editorial policy. And this is exactly the result they risk with that policy. /4

For as long as I can remember, they've always made it quite explicit, that their editors reign supreme and reviewers only advise them - and that this goes in bnoth directions.

In the words of now infamous Declan Butler, "peer-review light": the non-peers are making the main decisions and the peers are relegated to the back-seats.

@brembs

But an example where they admitted that just one out of three referees supported the publication of a specific paper, even after two revisions?

@BorisBarbour

I have been told of such examples (and also of the reverse), but cannot recall a publication/artilce where it is reported in writing, no.

Didn't mean to disagree with the point that this was a rare, very clear example, sorry!

@brembs

One case I'm still curious about is the 2014 STAP stem cell scandal. There, referee reports emerged (from authors during the inquiry) for the first submission, but none for the revision. The suspicion was that it had been accepted without further review. But that was never confirmed.

@BorisBarbour

Yes, interesting case! Haven't heard anything from there, me neither.
