Is Dias bringing the bus back?

So Physical Review Letters formally retracted that paper about manganese sulphide, in the limelight for having been coauthored by Ranga P. Dias, yesterday. The retraction notice states: “Of the authors on the original paper, R. Dias stands by the data in Fig. 1(b) and does not agree to retract the Letter.” Figure 1(b) is reproduced below.

The problem with the second plot is that its curves reportedly resemble some in Dias’s doctoral thesis from 2013, in which he had examined the same properties of germanium tetraselenide, a different kind of material. Curves can look the same to the extent that they can have the same overall shape; it’s a problem when they also reproduce the little variations that are a result of the specific material synthesised for a particular experiment and the measurements made on that day.

That Dias is the only person objecting to the retraction is interesting because it means one of his coaouthors, Ashkan Salamat, agreed to it. Salamat heads a lab in the University of Nevada, Las Vegas, that’s been implicated in the present controversy. Earlier this year, well after Physical Review Letters said it was looking into the allegations against the manganese sulphide paper, Scientific American reported:

Salamat has since responded, suggesting that even though the two data sets may appear similar, the resemblance is not indicative of copied data. “We’ve shown that if you just overlay other people’s data qualitatively, a lot of things look the same,” he says. “This is a very unfair approach.”

Physical Review Letters also accused Salamat of attempting to obstruct its investigation after it found that the raw data he claimed to have submitted of the group’s experiments wasn’t in fact the raw data. Since then, Salamat may well have changed his mind to avoid more hassle or in deference to the majority opinion, but I’m still curious if he could have changed his mind because he no longer thought the criticisms to be unfair.

Anyway, Dias is in the news because he’s made some claims in the past about having found room-temperature superconductors. A previous paper was retracted in September 2022, two years after it was published and independent researchers found some problems in the data. He had another paper published in March this year, reporting room-temperature but high-pressure superconductivity in nitrogen-doped lutetium hydride. This paper courted controversy because Dias et al. refused to share samples of the material so independent scientists could double-check the team’s claim.

Following the retraction, The New York Times asked Dias what he had to say, and his reply seems to bring back the bus under which principal investigators (PIs) have liked to throw their junior colleagues at signs of trouble in the past:

[He] has maintained that the paper accurately portrays the research findings. However, he said on Tuesday that his collaborators, working in the laboratory of Ashkan Salamat, a professor of physics at the University of Nevada, Las Vegas, introduced errors when producing charts of the data using Adobe Illustrator, software not typically used to make scientific charts.

“Any differences in the figure resulting from the use of Adobe Illustrator software were unintentional and not part of any effort to mislead or obstruct the peer review process,” Dr. Dias said in response to questions about the retraction. He acknowledged that the resistance measurements in question were performed at his laboratory in Rochester.

He’s saying that his lab made the measurements at the University of Rochester and sent the data to Salamat’s lab at the University of Nevada, where someone else (or elses) introduced errors using Adobe Illustrator – presumably while visualising the data, but even then Illustrator is a peculiar choice – and these errors caused the resulting plot to resemble one in Dias’s doctoral thesis. Hmm.

The New York Times also reported that after refusing in the past to investigate Dias’s work following allegations of misconduct, the University of Rochester has now launched an investigation “by outside experts”. The university doesn’t plan to release their report of the findings, however.

But even if the “outside experts” conclude that Dias didn’t really err and that, honestly, Salamat’s lab in Las Vegas was able to introduce very specific kinds of errors in what became figure 1(b), Dias must be held accountable for being one of the PIs of the study – a role whose responsibilities arguably include not letting tough situations devolve into finger-pointing.

NCBS retraction – addenda

My take on the NCBS paper being retracted, and the polarised conversation that has erupted around the incident, is here. The following are some points I’d like to add.

a. Why didn’t the editorial and peer-review teams at Nature Chemical Biology catch the mistakes before the paper was published? As the work of famous research-fraud detective Dr Elisabeth Bik has shown, detecting image manipulation is sometimes easy and sometimes hard. But what is untenable are claims by some scientists, and journals as well, that peer-review is a non-negotiable requirement to ensure the scientific literature remains of ‘high quality’. Nature Chemical Biology also tries to launder its image by writing in its retraction notice that the paper was withdrawn because the authors could not reproduce its results. Being unable to reproduce results is a far less egregious offence than manipulating images. What the journal is defending here is its peer-review process.

b. Nature Chemical Biology continues to hold the retracted paper behind a paywall ($9 to rent, EUR 55.14 to subscribe to the journal for a year). I expect readers of this blog to know the background to why paywalls are bad, etc., but I would have thought a retracted paper would be released into the public domain. It’s important for everyone to know the ways in which a paper was flawed post-retraction, especially one that has commanded so much public attention (at least as retractions go). Unless of course this is Nature Chemical Biology acknowledging that paywalls are barriers more than anything else, and the journals’ editors can hide their and their peer-review’s failure this way.

c. The (now retracted) Arati Ramesh et al result was amazing, etc. but given some social media conversations are focused on why Ramesh didn’t double-check a result that was so significant as to warrant open celebration once the paper was published, some important background info: the result was great but not entirely unexpected. In April 2020, Jianson Xu and Joseph Cotruvo reported that a known riboswitch that bound to nickel and cobalt ions also had features that allowed it to bind to iron. (Ramesh et al’s paper also cites another study from 2015 with a similar claim.) Ramesh et al reported that they had found just such behaviour in a riboswitch (present in a different bacterial species). However, many of the images in their paper appeared to be wholly manipulated, undermining the results. It’s still possible (I think) that someone else could make a legitimate version of the same discovery.

Appa Rao Podile made fellow of science academy that published his problem paper – some questions

Appa Rao Podile, the former vice-chancellor of the University of Hyderabad, has been elected a fellow of the Indian National Science Academy (INSA) in spite of one of his three papers – which The Wire had identified in April 2016 as containing evidence of plagiarism – having been published by the academy. According to the citation, he “has made important contributions in the field of plant-microbe interactions. His work on chitinases has enabled the development of alternatives to toxic antifungal compounds for plant protection.”

INSA is one of India’s three science academies. The other two are the National Academy of Sciences and the Indian Academy of Sciences. Between them, they’ve formally divvied up an agenda of three portfolios. The National Academy of Sciences handles women in science; the Indian Academy of Sciences handles science education. And INSA, ironically, handles ethics.

The paper Appa Rao had coauthored (and for which he also the lead author) and published by the journal Proceedings of the INSA in 2014 was titled ‘Root Colonisation and Quorum Sensing are the Driving Forces of Plant Growth Promoting Rhizobacteria (PGPR) for Growth Promotion’. It contained six instances of plagiarism – the most among the three papers. After The Wire had reported on the offence, Appa Rao assumed complete responsibility and apologised for his mistakes. Proceedings of the INSA also issued a clarification accompanying the paper.

Two scientists I spoke to said on condition of anonymity that Appa Rao Podile’s election only damaged the credibility of the academy. Om Prasad, a history student at JNU, added, “He cannot be a role model for any aspiring researcher in the sciences or in academia in general” for having handled the Rohith Vemula suicide and protests the way he did (almost completely devoid of dignity) and for his plagiarism in various papers.

This is an issue I’d explored in January this year, when Appa Rao had been awarded the ‘Millennium Plaque of Honour’ by the Indian Science Congress (ISC). The plaque is awarded every year by the congress’s organisers to ’eminent’ scientists. In a time when the ISC’s credibility has been flagging, and considered by many scientists to be a waste of time, it is odd that the award would be given to someone whose administrative and academic credentials are in question. I expected the INSA also would’ve had similar considerations – but no.

I’d asked A.K. Sood (INSA president), Subhash Lakhotia (senior scientist at the academy) and Lahiri Majumdar (plant sciences editor of the Proceedings of the INSA) about these issues. In response, I got a carefully worded statement from Alok K. Moitra, the secretary of fellowships at the academy. I’ve pasted the bulk of it below; only one paragraph has been left out because it discussed a set of emails exchanged between INSA members and me last year.

The question of plagiarism in an article published by him and his colleagues in one of the issues of the Proceedings of the INSA was thoroughly examined by the editorial office of the journal immediately following the allegation made by you in April 2016. The examination revealed that although there were instance of similarities in five-six isolated sentences with some earlier publications, none of them would qualify for typical plagiarism since these did not pertain to someone else’s data. These were general statements, some of which may not need any specific citation as such. Being general in nature, they are also likely to share variable strings of words. Nevertheless, the authors did publish a note of apology in a later issue of our journal for inadvertent identity/similarity of a few isolated sentences in the published paper with those in some other papers.

The INSA Council while discussing the election of Professor Appa Rao Podile to fellow of INSA considered this allegation and decided that the allegation of plagiarism was without merit. His election to the Fellowship of INSA is based on his scholastic research contributions.

§

Based on these facts, I have a few questions. But before that, a short note (just in case for some idiotic readers who comment on a story without reading it first): I’m not saying at all that we forgive Appa Rao Podile for the way he dealt with the students and faculty at the University of Hyderabad campus (under political pressure to boot) as well as for the way he conducted himself when a police inquiry was initiated against him.

1. Appa Rao admitted to his mistake and issued a correction and an apology (subsequently publicised by the journal). His misconduct wasn’t in the experiment but in the descriptive part of the paper. Prasad argued that none of this exculpates him – but this is quite in opposition to what former UGC chairman Praveen Chaddah had written in 2014: that entire papers shouldn’t be retracted or dumped when misconduct like plagiarism is confined to the paper’s descriptive parts and doesn’t spillover into the data or experiment itself. I don’t know where I myself stand, but I think there’s some introspection to be done here about whether we’re being too strict apropos Appa Rao’s plagiarism infraction because of his role in the University of Hyderabad protests, violence, etc.

2. An obvious follow-up question arises: when we’re felicitating a scientist for his scientific accomplishments and electing him as a fellow of a reputed science academy, are we allowed to pull up the academy for not having considered his non-scientific work as well? (I realise this is a loaded question because it suggests that I’m not going to be happy with the academy until it recants its fellowship offer, but no – I’m actually curious.)

3. Are we paying attention to the academy itself only because it has elected a controversial fellow? I know my answer is ‘yes’. India has three science academies and they rarely ever feature in public conversations about science in India, so it feels somewhat embarrassing to suddenly consider the INSA to be important. And part two: do we expect all the fellows at India’s science academies to be role models? If we’re going after Appa Rao now because he’s not been a model citizen, shouldn’t we be asking such questions of all the fellows of the three academies?

4. Should our consternation at Appa Rao’s election be directed towards Appa Rao or towards INSA? Common sense would dictate that we divert our scrutiny towards INSA. And we immediately realise that as much as Appa Rao had erred in plagiarising in his paper, INSA had also erred in publishing the document without checking it for plagiarism first. We find further that the INSA guidelines for the election of new fellows is insipid, making no room to consider the possibility that some scientists may be great with the science but jerks at other things. There are also no guidelines for what actions it would take against a fellow should he be implicated for some offence in the future (and gradations therein). What happens when the fellow of a science academy commits murder? (Can you imagine anyone rushing to find out what INSA/IAS/NAS is saying?)

Update: I’d had a follow up question for Moitra, to which I received a reply late yesterday.

Q: Apart from Appa Rao’s academic credentials, did INSA consider his administrative track record at the University of Hyderabad? Did it consider the fact that a fact-finding team (of three well-regarded academics) concluded that Appa Rao had acted unethically and in a way damaging to the reputation of the University during his term as VC? Wouldn’t Appa Rao’s election to the academy thus seem as if – as long as a scientist does good science, his other transgressions can be ignored?

A.K.M.: In our earlier response, we did state that the election was based on scholastic achievement. Administrative failures/successes can be subjective impressions depending upon from which angle one looks at it. Election to fellowship is essentially on the basis of scientific contributions. However, only if there are established cases of wrong-doing as judged by the judiciary system of the country, the election would not be made in spite of scholastic achievements.

The Indian Science Congress has gutted its own award by giving it to Appa Rao Podile

Featured image credit: ratha/Flickr, CC BY 2.0.

I hadn’t heard of the Millennium Plaque of Honour before yesterday, January 3. From what I was able to read up before filing my report in The Wire (about embattled Hyderabad University vice-chancellor Appa Rao Podile receiving the plaque at the ongoing Indian Science Congress):

  1. It has been awarded by the Indian Science Congress Association since 2003, when it was instituted as the ‘Science & Society Award’
  2. Its name was changed to the New Millennium Plaque of Honour in 2005
  3. It carries a citation, a literal plaque and a cash component of Rs 20,000 “to cover incidental expenses”
  4. It is awarded to two eminent scientists at the Science Congress every year

If the annual event was considered prestigious or even very laudable until 2014, I’m not entirely sure (although it certainly wasn’t a very gala affair). But in 2015 and after, it’s certainly taken a beating. In 2015, particularly, the congress was invaded by right-wing nuts convinced that Vedic age scholars had flown planes to Mars and transplanted animal heads onto human bodies. Proceedings were relatively free of controversy in 2016 before taking another turn for the worse in 2017: by giving a Millennium Plaque to Appa Rao (as well as to Avula Damodaram, but that’s a lesser problem we’ll come to later).

A day or so ago, in a conversation on Twitter, both R. Prasad (The Hindu‘s science editor) and Gautam Desiraju (a celebrated chemist at the Indian Institute of Science, Bengaluru) agreed that many Indian events had off late been banking on legitimacy ‘loaned’ from foreign institutions. For example, a large part of the Indian Science Congress’s public outreach every year involves blaring that X Nobel laureates will be in attendance. Nobel laureates are eminent people men, sure, but often they don’t do much other than give a talk and just be in attendance. And their presence doesn’t do much for the quality of the conference, overall in a decline, either (see footnote). In December 2012, P. Balaram, the director of IIT-Madras, wrote in an editorial in the journal Current Science,

… few practising scientists of note consider the Congress as an important event. Pomp and ceremony take precedence over substance. Over the years the Congress has been reduced to an occasion where the inaugural session appears to be the raison de etre for the meeting. The traditional opening address by the Prime Minister predictably reiterates governmental commitment to support science and invariably promises to remove the many bureaucratic hurdles that sometimes loom larger than life in the minds of many scientists. The presence of the executive head of government invests the inaugural event with an importance that is often not commensurate with the quality of the scientific sessions that follow. The occasion is also used to showcase a couple of Nobel laureates, who fly in to speak to audiences with little appetite for excessively technical talks. The organisers, bolstered by considerable government backing, are always good hosts; the distinguished foreign presence ensuring that the Congress always acquires a degree of respectability rarely supported by the scientific program.

In such times, the value of reinforcing local rewards, recognitions, symbols, ideals, etc. is as important as respecting and re-legitimising them as well. This means that an award like the Millennium Plaque of Honour (despite its pompous name), instituted as it has been by the Indian Science Congress, should be given on every occasion to scientists truly deserving of the award and, more importantly, never to anyone who will lower by association the prestige accorded to the award.

Appa Rao is capable of doing the latter. Particularly after Rohith Vemula’s suicide last year (and more generally for a half-year period before that), Appa Rao, as vice-chancellor, was responsible for allowing partisan interventions from the Bharatiya Janata Party (BJP) to interfere in university student politics as well as for violently quelling student protests that followed on the University of Hyderabad campus. Shortly after the news of Vemula’s death broke, the Times of India also reported that Appa Rao had acquired his vice-chancellorship through political connections, especially with BJP minister Venkaiah Naidu and Telugu Desam Party chief Chandrababu Naidu.

A relevant passage from our coverage of the incidents:

Police, CRPF and RAF forces came to the campus, and students assembled on the lawns outside the VC’s lodge were brutally removed and lathi charged. Some students were badly injured and had to be taken to hospitals, sources have said. Students have also said that they were abused and insulted, and female students were threatened with rape. Students from minority communities were allegedly called “terrorists”.

It’s impossible to overlook the fact that his only presence in recent memory was as a craven but powerful stooge, and in fact almost never for his work as a scientist. He hasn’t done anything memorable of late nor as he displayed the integrity due a vice-chancellor of a public institution. In fact, shortly after the student protests, I had also published evidence of plagiarism in three of his research papers. If he has won a Millennium Plaque, then it only means the ‘honour’ doesn’t stand for research excellence anymore as much as for neglecting one’s duties and for perverting the all-important autonomy of an important position.

Worse yet, it seems an award of the Indian Science Congress has become subverted into becoming an instrument of negotiation for political agents: “You let me interfere in your duties, I will give you a fancy-sounding award”. The other recipient of the same award this year, Avula Damodaram, doesn’t inspire confidence, either – although I concede I have no evidence following my suspicions (yet). Damodaram is the vice-chancellor of Sri Venkateswara University, Tirupati, the same institute that’s hosting the science congress this year. Binay Panda, a bioinformatician and friend, wasn’t surprised:

Footnote: Mukund Thattai, a biologist at the National Centre for Biological Sciences, Bengaluru, conducted a poll on Twitter asking why people took to science. The option ‘once saw a Nobel laureate’ clocked in last:

Seventy-four is not a great sample size but 1% is a far more abysmal number.

Podile, plagiarism, politics

On 17 January, Vemula hung himself, saying in his suicide note, “my birth is my fatal accident.” His death has rocked academia, with unabated protests on the Hyderabad campus and elsewhere. Even before the incident, Tandon and others openly referred to Appa Rao Podile, the university’s vice chancellor, as the famed institution’s first political appointee. Appa Rao has since left the university on indefinite leave.

This is from a February 3, 2016, blog post on Scientific American by Apoorva Mandavilli. I quote this to answer the question I’ve been asked throughout today from different people: “Why did you not publish your piece on three of Appa Rao’s papers containing plagiarised content earlier or later?” (The link to my piece, which appeared on The Wire, is here.) Appa Rao, as Mandavilli writes, is the university’s first VC to be appointed via the political route. In fact, according to The Times of India, he once campaigned for the Telugu Desam Party.

My piece was put together over three or four days – from the time I found out about the issues in Appa Rao’s papers to when I had all the information necessary to put my article together. Finally, though its publication date was postponed by a day thanks to the release of the Panama Papers, nothing else was taken into account apart from checking if The Wire had done due diligence before hitting the ‘Publish’ button. Having said all this, I ask: if Appa Rao is the first politically appointed VC at the University of Hyderabad, how can anything he does not be examined through a political lens?
