Jessus investigator identity leaked, CNRS President to expose whistleblowers

Jessus investigator identity leaked, CNRS President to expose whistleblowers

An update to the ongoing cartoon Stalinism propaganda and purge activities at the EU largest research institution, the French CNRS, in the wake of the affair around manipulated data of CNRS chief biologist Catherine Jessus, according to their press release an innocent “victim” of my “slanderous” and “unscientific” blogging.  First of all, a reliable source forwarded to me information from inside CNRS who one of the anonymous investigators was: Francis-André Wollman, CNRS researcher and professor at Jessus’s university UPMC (now Sorbonne University) in Paris. Wollmann is plant cell biologist, specialising in chloroplasts, the technology of western blot is standard in his lab. He did not reply to my emails, also the CNRS and Sorbonne University press speakers chose not to deny his role as anonymous Jessus investigator. The experts namely declared western blot manipulation to be good scientific practice, and lashed out at those who have a problem with copy-pasted gel bands (read here).

Then, the new CNRS President Antoine Petit, who replaced interim president Anne Peyroche (deposed after my reporting about data manipulations in her papers) proved to be not really a reformer, quite the opposite. Petit approved the new definition of what research misconduct in biology is, following cues from Sorbonne University and its president Jean Chambaz (who is cell biologist, specialising on intestinal metabolism and thus also a western blot expert), as well as Wollman and other Jessus investigators. New Sorbonne and CNRS Party doctrine is that data manipulation is definitely not research misconduct, but criticising that data manipulation is.

This is how Petit responded to the Jessus affair in public so far:

  • Called myself and other PubPeer commenters “arseholes” (in French connards) at his first meeting with the section heads of CNRS (one of whom is Jessus)
  • Claimed that PubPeer evidence and my reporting was an accusation of misconduct directed personally at Jessus and Peyroche (a lie, check my articles here and here), in this radio interview.
  • Described documented and now validated data integrity concerns raised against publications by Jessus and Peyroche as equivalent to false accusations of pederasty (then corrected to paedophilia), in same radio interview.
  • Announced to use IT surveillance technology to identify anonymous PubPeer commenters after their evidence was exposed as “wrong” (as it was in case of Jessus), in same radio interview.

Pravda of Jessus report, CNRS Politburo scared of own people

Pravda of Jessus report, CNRS Politburo scared of own people

Following my recent article about attempts to fix data irregularities in the papers by CNRS’ chief biologist and director of l’Institut des sciences biologiques (INSB) Catherine Jessus, this state-owned French research institution, the biggest in Europe, now went full Pravda. Just as the notorious propaganda newspaper of the Communist Party of the Soviet Union (Pravda means Truth in Russian), CNRS press release of February 21st about the Jessus misconduct investigation combines lies, disinformation, and thinly veiled threats and calls for mass denunciation of traitors. The foreign enemy of French science is clearly identified: myself, the slanderous blogger.

All that would be mildly entertaining, were it not for the main victim of that investigative report: research integrity. We learn from that Soviet-style propaganda piece that Jessus took responsibility for almost all of the data manipulations in her papers, in fact even more data integrity problems emerged during the investigation, in figures previously not flagged either on my site or on PubPeer. Jessus was tasked by the commission to analyse her own incriminated figures herself, and to report her findings to her investigators. These professors of the l’Université Pierre et Marie Curie (UPMC, now Sorbonne University) who wisely chose to hide their identities (while decrying same with PubPeer commenters, sic!) had then the cheek to actually endorse the practice of data manipulations, in a public document, most astonishingly that of gel band duplications across different gel images, “for reasons of visual symmetry”. In other instances of cloned gel bands, the investigators spoke of scientifically-irrelevant “assembly errors” of western blots. No, not of separate antibody panels. Of individual gel images. They do not believe in monolithic photographs of an experimental gel, but prefer those as a digital puzzle or a collage, to be assembled from various bits and pieces in Photoshop, where a scientist sometimes inadvertently slips and uses the same gel band or bit of background twice.

Masquerading  research misconduct as good scientific practice is a form of scientific misconduct in itself. It doesn’t matter if these so-called experts really believed into the greater good of data manipulations, or strategically trolled the scientific community under cover of anonymity to save Jessus from herself, or were professionally unqualified to judge on the matters of biological science. Their decision not to see any misconduct despite ascertained evidence, while appropriating the entire blame onto those who blew the whistle, was borderline criminal, considering the circumstances. These dishonest UPMC investigators should be dragged out of their anonymity and publicly shamed and disciplined for the damage they just did to the reputation of French science.

CNRS: chief biologist Catherine Jessus “victim of slanderous campaign” by blogger

CNRS: chief biologist Catherine Jessus  “victim of slanderous campaign” by blogger

UPDATED. My earlier reporting about image irregularities in the papers by CNRS’ chief biologist and director of l’Institut des sciences biologiques (INSB) Catherine Jessus had some interesting effects, including two Corrigenda I discuss below. Evidence of data manipulation in several Jessus’ co-authored papers on cell cycle progression in Xenopus oocytes was collected by my readers, which I then posted on PubPeer. There, it was soon supplemented with additional evidence from other PubPeer users. CNRS now publicly accused me of  “slanderous campaign” against Jessus, declared gel band duplications to be either technical incidents or in fact scientifically well justified and called its scientists to “collective vigilance” against people like myself (see below).

While CNRSan institution of of 32,000 research employees and annual budget of €3.2 Billion, was busy suppressing the Jessus affair (allegedly on orders from the French Ministry of Higher Education, Research and Innovation), something even bigger exploded: evidence of data manipulation appeared in the papers of the then-interim President of CNRS, Anne Peyroche, which then led to her removal and institutional investigation which could result in sacking. My own role in reporting data manipulations in Peyroche papers, initially dismissed as so-called compression artefacts by PubPeer moderation, was then acknowledged by Le Monde. The French national newspaper also brought the well-hidden Jessus case into the spotlight:

It’s also on PubPeer that Catherine Jessus, head of research in biology at CNRS, was incriminated – she did not consider it appropriate to answer on the site”.

Unlike the unlucky CNRS interim president, behind whose devastating PubPeer postings Retraction Watch suspectedpolitical motivations in trying to take Peyroche down“, the powerful CNRS’ chief biologist apparently doesn’t have to answer to anyone. Jessus was whitewashed in a secret investigation by l’Université Pierre et Marie Curie (UPMC), which professorship she holds. UPMC experts found only minor errors in 3 Jessus publications, and dismissed all other evidence.

Two Jessus papers have now been corrected, a key co-author on those is Aude Dupre, Jessus former PhD student and presently staff scientist at UPMC. Another coauthor is Olivier Haccard, “Directeur de Recherche” at CNRS I2BC in Paris. These papers from 2017 and 2015 were relatively simple cases, where no gel band duplications were spotted. One could even have explained those away as honest mistakes of negligence. But Jessus’ corrections of these two recent papers are not that straightforward, and do little to dismiss suspicions of her lab’s lack of research integrity.

Anne Peyroche removed as interim CNRS President as her publications are “questioned”

Anne Peyroche removed as interim CNRS President as her publications are “questioned”

Things are happening at the French state’s network of research institutes, Centre National de la Recherche Scientifique (CNRS). Their interim president, Anne Peyroche, was now removed prematurely from her position due to evidence of data manipulations in her papers on PubPeer, which I helped uncover. As all credit goes to PubPeer (run chiefly by two CNRS researchers), the announcement unfortunately makes no reference to my call for a minor revolution at CNRS, where these data manipulations were presented to wider public. The official letter which I obtained, is below, both in English translation and its French original.

Another problematic CNRS chief scientist, Catherine Jessus, who as director of l’Institut des sciences biologiques (INSB) is the head biologist at CNRS, was acquitted in November 2017 by a secret investigation at l’Université Pierre et Marie Curie (UPMC) despite all that long list of suspected data manipulations found in her papers (which I originally presented in this article). As Peyroche faces disciplinary investigation by her employer, the Commissariat à l’énergie atomique et aux énergies alternatives (CEA), nothing of that kind seems to threaten Jessus. Instead, those CNRS researchers who dare to protest against her  research integrity shortcomings are being threatened and terrorized, by a furious Jessus herself and her supporters at the top of CNRS.

Finally, a particularly data manipulations-ridden Institut de Biologie Moléculaire des Plantes (IBMP) in Strasbourg, former home of the legendary Olivier Voinnet (whom Jessus once investigated for doing those same naughty things she might have just a sbadly engaged herself in) has issued a Code for Ethics and Responsible research, which warns potential perpetrators:

IBMP defines scientific misconduct as:

The selective manipulation, fabrication or falsification of scientific data.

Thing is, IBMP director Laurence Maréchal-Drouard with her PhD student and now tenured lab member Thalia Salinas recently went to PubPeer to admit exactly this kind of misconduct, after I published evidence of data manipulations in Drouard’s many publications and Salinas’ doctorate thesis.

Call to research integrity, or at least a minor revolution at CNRS

Call to research integrity, or at least a minor revolution at CNRS

When I first started digging into the affair of data manipulations around the former star of plant sciences Olivier Voinnet in early 2015, I was sure to be dealing with a singular case of fraud in French science, which went totally unnoticed for decades. When 2 years later I wrote “a fish stinks from the head down” in my article about Voinnet’s former Strasbourg plant sciences institute and its problematic director, I did not know how far up to the very top this data manipulation scandal will go. Now, it looks like the entire leadership of  the Centre National de la Recherche Scientifique (CNRS), French state’s own network of research institutes, might be corrupted and rotten. Research and its integrity at this “largest fundamental research organization in Europe” are overseen by the very people whose own publications should be under investigation for suspected misconduct. A minor revolution is in order in French science, for which I would like to make a case here.

The new interim president of the entire CNRS of 32,000 research employees with the annual budget of €3.2 Billion, Anne Peyroche, has seen now her own publications flagged on PubPeer for data irregularities. In fact, PubPeer itself, which is run by two CNRS employees, seems to be in a pickle. They now vigorously police and delete attempts of criticisms of Peyroche papers. Is the whistleblowing site fighting for its survival, afraid that CNRS might impose its demise any time? How far is the CNRS’ leadership prepared to go, now that their power is threatened by the evidence of misconduct in their own papers?

Catherine Jessus, being the director of its l’Institut des sciences biologiques (INSB) basically the head biologist at CNRS, already reacted to a stream of evidence against her publications on my site and on PubPeer. No, she is apparently not going to check lab books or provide for original data. Instead she declared to her colleagues that CNRS will soon start a massive legal action against yours truly. If true, the State of France announced to soon set its power and resources upon a German blogger, yet the French media refuses to report anything until CNRS issues an official statement in this regard. This information I have from direct sources.

CNRS hits back at the stream of misconduct evidence

CNRS hits back at the stream of misconduct evidence

The French scientific society CNRS, a huge country-wide network of research institutes and one of the most influential science institutions in Europe, had enough of me and my reporting. They now blocked me on Twitter, so I don’t spoil their celebration of a book by their senior director and chief of research integrity, Catherine Jessus. The book is titled “Étonnant vivant”, which translated roughly means “Amazing ways to improve your Life science publications with just a little bit of photoshop”. I previously reported about some examples of this art in Jessus publications, which CNRS did not really appreciate.

And of course CNRS did not take it lightly when my past reporting forced them to deal with the Olivier Voinnet affair, whose investigator was Jessus. Neither did they like my writings about another misconduct scandal she had very successfully kept under wraps, that around the former Voinnet postdoc Charles-Henri Lecellier, now CNRS group leader in Montpellier. What finally took the biscuit was my constant leaking of misconduct evidence and of internal information from the former Voinnet institute in Strasbourg,  Institut de Biologie Moléculaire des Plantes (IBMP), or as I keep proposing to rebrand it, The Olivier Voinnet Institute for Research Integrity in Plant Sciences. CNRS initially tried it nicely, by sending the IBMP deputy director Jean-Luc Evrard to call me “baby”, then “idiot”, while instructing all other institute employees never to communicate with me, and eventually CNRS simply blocked me on Twitter.


On this occasion, I will now bring more evidence on data rigging inside IBMP. Before dumping new evidence about the IBMP director Laurence Maréchal-Drouard, let us start with something traditional and well known, namely Voinnet and his sidekick Patrice Dunoyer, whose IBMP lab was supposed to be dissolved, but maybe he managed to save himself with a recent publication in Nature Plants.

Voinnet’s CNRS investigator Catherine Jessus with own data integrity issues

Voinnet’s CNRS investigator Catherine Jessus with own data integrity issues

More suspected data manipulations in the papers by the French elite biologists. It was funny enough when the director and several lead figures at the Strasbourg CNRS institute for plant sciences IBMP, former home of the master data manipulator Olivier Voinnet, and even the institute’s evaluators, were found to sport quite a lot of shifty-looking data in their papers. This time, the irony is just too much. Catherine Jessus, developmental biologist specialising on cell cycle research on oocytes and director of CNRS l’Institut des sciences biologiques (INSB) was in charge of two misconduct cases, and now the data integrity of her own papers is called in question. One investigation led by Jessus was about, whom else, Voinnet and his IBMP sidekick Patrice Dunoyer. In summer 2015, Voinnet was barred from CNRS for 2 years (which sounds worse than it is, because his professorship at ETH Zürich in Switzerland remained untouched, read here), and Dunoyer was suspended for one entire month. Jessus’ secret investigation ended with no documents whatsoever but a terse press release made available to outsiders. Both Voinnet and Dunoyer are by now back to publishing papers in prestigious journals.

Jessus was also in charge of dealing with the misconduct evidence against Voinnet’s former postdoc Charles-Henri Lecellier, whom the mighty plant scientist (according to my sources) banned from his Strasbourg lab because he did not trust his research results. It seems Lecellier started to fudge data already during his PhD at CNRS Hôpital Saint-Louis in Paris (PubPeer record here). Imagine how bad it must get that Voinnet expels you for data manipulation! The tenured CNRS researcher was hence moved out of Voinnet’s sight, to work as group leader at the Institut de Génétique Moléculaire de Montpellier, where he continued his own line of data rigging, helped by his trusted friend from IBMP, Guillaume Vetter (see my earlier reporting for a German magazine here and here). Apparently, with full protection from CNRS: in 2013 Jessus actively opposed on behalf of CNRS the impending retraction of a Lecellier co-authored paper, despite earlier misconduct findings against his partner Vetter at the University of Luxembourg (evidence here, especially this letter, example of data manipulations here).
