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

Nature did try to deal with the mess when they received complaints about the data, and they ended up retracting the paper. Gone are the days of stonewalling all such problems, and good riddance.

Procedures can certainly be improved, though. Co-authors (students) had been kept out of the loop during the investigation, which they only discovered when asked if they agreed with the retraction. Obviously they should have been contacted as soon as the investigation began. /5

Incredibly, Nature then accepted another paper from Dias about a new superconducting material.

EiC Magdalena Skipper: "Our editorial policy considers every submission in its own right”. That policy is shown to be dangerously naive.

Also: "decisions should be made on the basis of the scientific quality, not who the authors are." This paper was an embarrassing failure of evaluation. How do Nature aim to improve their processes? /6

Nature were not helped by the institution, Rochester University. They conducted four investigations and only the *fourth* identified any problems. During none of the first three were any of the students contacted! Simply pathetic. Nobody, including journals, should rely on (non-transparent) institutional investigations. /7

Funders control money and could effect real change in both researcher and institutional behaviour. If they (the funders) took the slightest interest.

Neither the DoE nor the NSF was able to offer any comment about the affair. Draw your own conclusions about their priorities.

Congratulations to Dan Garisto, the author of the piece.

What I don't understand (other than the three institutional investigations that didn't involve the students) is - how did he hope this would play out long term? Did he think that other physicists - and the investors in his company - would just accept the claims, without replications or even strong evidence from his own lab, indefinitely? For the rest of his career?

It is hard to know.

I suspect he had been successful for a quite a long time already with lies and evasions, and had grown used to that. The lies got bigger. (In fact, that's all been established already.)

He maybe has no real understanding of scientific truth, focusing instead on social and financial indicia of success, and the social/political approaches to achieving them. That may be how he sees the world and how he believes everybody else does.
