Science Integrity Digest – catching up

Apologies for not posting for a while. Fall 2024 was a busy time for me, with travel to give talks in Australia and Singapore and some events in the US. Instead of trying to catch up with everything that has happened since September, here are some highlights.

Einstein Foundation Award

I’m thrilled to have won the 2024 Einstein Foundation Award for Promoting Quality in Research. The Einstein Foundation Berlin selects three winners each year. The 2024 winners are:

  • Early Career Award: Helena Jambor and Christopher Schmied at PixelQuality – Best practices for publishing images. ‘PixelQuality has established guidelines and checklists for publishing clear and reproducible images. It now aims to disseminate and refine them to handle AI-assisted image generation and analysis.’ ‘Research images are the proof of scientific findings, not just visuals. PixelQuality has set new standards for their reproducibility and transparency.
  • Institutional Award: PubPeer – ‘PubPeer has become an essential part of the research communication landscape, with over 300,000 comments logged so far. It is estimated that since 2012, 19 percent of all retractions of papers worldwide in all academic domains had a prior discussion on the site. Beyond identifying flaws and fraud, PubPeer functions as an important tool to jointly improve scientific publications through „liquid feedback“.
  • Individual Award: Elisabeth Bik – ‘Elisabeth Bik’s work in uncovering manipulated images, fraudulent research data and publications has created enormous impact all over the world. Her work has led to heightened awareness of questionable research practices and generated widespread attention to responsible conduct of research in the scientific community.

The award ceremony will take place in March 2025 in Berlin, Germany.

The Bik Fund

Instead of accepting the Einstein Foundation award money for myself, I’ve decided to put it into ‘The Elisabeth Bik Science Integrity Fund’ – where I hope to help other science sleuths with small grants for e.g., traveling to conferences, buying equipment or software, or training. Our type of work often does not fit into the hypothesis-driven model of government or charity funds, so I hope to help by filling this funding gap.

The Bik Fund will be part of The Center For Scientific Integrity, Retraction Watch’s parent 501(c)3 non-profit organization.

It is my hope that we can make this fund grow, so we can help more integrity warriors in the future – donations to the Bik fund are tax-deductible and very welcome.

Doctored

Charles Piller’s new book ‘Doctored – Fraud, Arrogance, and Tragedy in the Quest to Cure Alzheimer’s’ came out earlier this month.

The book describes how Matthew Schrag, a neuroscientist at Vanderbilt University and a fellow image-sleuth, discovered possibly altered images in a highly-cited paper about amyloid plaques in Alzheimer’s patients and in other papers connected to the biotech company Cassava Sciences (see also below). It also gives a disturbing insight into the amount of fraud in neuroscience and the lack of action by journals, institutions, and government agencies.

Matthew Schrag and other ‘science sleuths’—Kevin Patrick, Mu Yang, and I—worked for two years checking thousands of papers in Alzheimer’s research and related fields for the book, uncovering a concerning number of potential problems in papers by Sylvain Lesné, Berislav Zlokovic, Eliezer Masliah, and others.

Cassava Sciences Phase 3 did not work

I have written in the past (here and here) about problematic images in papers by Dr. Hoau-Yan Wang and Cassava Sciences (NASDAQ: $SAVA), a biotech company testing a drug targeting Alzheimer’s disease. These concerns were first spotted by Matthew Schrag and published in a Citizen Petition, in an attempt to halt Cassava’s clinical trials. Despite the apparent problems, the FDA did not stop Cassava’s clinical trials of their Alzheimer’s drug, Simufilam. But Cassava’s stock dropped significantly, upsetting a lot of investors.

For three years, fans of the $SAVA stock harassed the Dr. Wang critics – including me – claiming that the drug would work fine; that all stockholders would be rich as long as they would HODL; and that all our concerns were FUD. They joined forces in a SAVAges Discord app, where they talked about how one day they would all buy Maseratis, Lamborghinis, and even a SAVA island — and how retarded and fraudulent the SAVA-critics were.

The authorities begged to differ, however. In March 2024, Science reported that FDA inspectors had found many problems in Dr. Wang’s lab, ranging from uncalibrated instruments, lack of control samples, and stored data files, to leaving out outliers based on subjective criteria. Another report by the City University of New York (CUNY) to the Office of Research Integrity (ORI), leaked to Science, described ‘egregious misconduct’ in Dr. Wang’s lab. In June last year the Department of Justice announced that Professor Wang had been charged with operating a ‘Multimillion-Dollar Grant Fraud Scheme’.

Meanwhile, lawsuits were filed back-and-forth. Cassava Sciences was suing the people who filed the FDA citizen petition and who set up the website CassavaFraud.com, while stockholders were suing Cassava in a class-action lawsuit for misrepresenting the quality of the experiments performed by Dr. Wang. The Securities and Exchange Commission (SEC) charged Cassava with misrepresenting clinical trials result, and later settled for $40M. And CUNY, instead of officially announcing their misconduct findings, was investigating who leaked their misconduct investigation report to Science.

Finally, last December the biotech company announced that the Phase 3 trial did not meet the anticipated endpoints. In other words, Simufilam did not halt or improve Alzheimer’s disease. The Cassava Sciences stock immediately dropped to $2-3 dollars, and the SAVAges Discord became a valley of despair. No more SAVA island.

Didier Raoult enters the Retraction Watch Leaderboard

As I’ve written previously, many papers from Professor Didier Raoult, the former director of the IHU Méditerranée Infection in Marseille, France, are problematic.

Some appear to contain manipulated images, while others describe research conducted without proper ethical permits. A number of Raoult’s studies were performed on vulnerable populations, such as homeless people, or on study participants in the Global South, which I [gasp!] dared to label neocolonial science.

As described in this paper by Fabrice Frank et al, the IHU-MI produced a set of 248 studies all with the same IRB approval number, 09–022. Despite sharing the same permit, the publications varied in terms of sample type, demographics, and countries. Other ‘multi-use’ IRB numbers were found too. Typically, an IRB approves one particular study, and researchers are not allowed to reuse this permit for other, unrelated, studies. Dr. Raoult appears to have cared little for such rules, however.

After raising our concerns on PubPeer and social media, and also writing to journal editors, several journals have started to issue Expressions of Concern and retractions.

Fabrice Frank has generated a list of all IHU-MI papers with concerns – there are over 800!

In fact, Raoult has now earned so many retractions (32 as of today) that he has entered the Retraction Watch Leaderboard. The most significant of them is the retraction of the paper that claimed that Hydroxychloroquine could treat COVID-19. I criticized this paper in my blog post in April 2020, days after its publication. It took more than four years to get it retracted.

With over 600 of his papers on PubPeer and 225 EoCs, it seems safe to assume that for Raoult’s position on the Retraction Watch Leaderboard list, the only way is up.

The rat with the big balls and the enormous penis – how Frontiers published a paper with botched AI-generated images

A review article with some obviously fake and non-scientific illustrations created by Artificial Intelligence (AI) was the talk on X (Twitter) today.

The figures in the paper were generated by the AI tool Midjourney, which generated some pretty, but nonsensical, illustrations with unreadable text.

It appears that neither the editor nor the two peer reviewers looked at the figures at all. The paper was peer-reviewed within a couple of weeks and published two days ago.

Dear readers, today I present you: the rat with the enormous family jewels and the diƨlocttal stem ells.

Problems in Harvard Medical School studies include images taken from other researchers’ papers and vendor websites

Over the last week I’ve been analyzing a set of papers from a research group at Brigham and Women’s Hospital, which falls under the Harvard Medical School. The papers have the usual image problems we unfortunately encounter so often, such as duplicated photos of mice and overlapping Western blots.

But this set also includes a 2022 paper that appears to have copied/pasted several figure panels from other researchers and even from scientific vendors. Most of these problems were found with ImageTwin or reverse image searches.

Quick links [the spreadsheet and slide have been updated with an additional problem found on Feb 2, 2024]:

Concerns about 12 MD Anderson Cancer Center’s Pathology Papers

As I was doing a reverse-image search online on a set of papers, I saw an unrelated photo of a skin biopsy that appeared to contain repetitive areas. Even in the small Google Image Search thumbnail it was clear to me that something unexpected was going on in this image.

The discovery led me to a set of 12 papers from a research group at the Hematopathology Department of the Texas MD Anderson Cancer Center, all with histopathology photos showing unexpected repetitive structures.

New Mendel University Rector found guilty of misconduct

In October 2020 and 2021 I reported a total of 21 papers published by Professor Vojtěch Adam that contained image problems. Vojtěch Adam is a professor in chemistry, and head of the Department of Chemistry and Biochemistry, at Mendel University in Brno, Czech Republic. He is a top Czech researcher in cancer and nanotechnology.

Today, a day before his appointment as the new Rector (Dean) of Mendel University, a committee released a report of their findings from an investigation into twelve of these papers. Their conclusions came as a big surprise.

Blast in the Past: Image concerns in paper about comet that might have destroyed Tall el-Hammam

Tall el-Hammam was a Bronze-Age city in current Jordan that is a site of archaeological interest. It is believed by some to be the biblical city of Sodom. According to the Bible, Sodom and Gomorrah were cities full of sinners, which were destroyed by “sulfur and fire” sent by God.

A paper published last week in Scientific Reports now claims that Tall el-Hammam was destroyed by a “cosmic airburst”, perhaps by the impact of a meteorite or comet. The article provides evidence of melted pottery and plaster, shocked quartz, and diamond-like carbon, all suggesting the city was exposed to a sudden high-temperature event.

The paper got a lot of media attention. However, several images presented in the paper appear to contain repetitive elements, suggestive of cloning.

Cassava Sciences: Of stocks and blots

A group of anonymous persons filed a Statement of Concern with the FDA regarding the integrity of research papers about Simufilam, an Alzheimer’s Disease treatment drug candidate developed by Cassava Sciences (Nasdaq: $SAVA). The petition raises concerns about Western blots and methodology. I took a look at the problematic photos included in the report, and agree with most of those concerns. I also found some additional problems.

Concerns about Marseille’s IHUMI/AMU papers – Part 1

Last March, I shared my concerns about a paper from the IHU-Méditerranée Infection (IHUMI)/ Aix-Marseille University (AMU) claiming that Hydroxychloroquine in combination with Azithromycin could reduce coronavirus viral loads faster than no treatment.

Other papers by this group of researchers led by Professor Didier Raoult and/or his right-hand man Professor Eric Chabrière, also appear to contain problems, ranging from potentially duplicated images to ethical concerns.

In this blog post I have gathered the papers by the Raoult and Chabrière group that have image concerns. This post is not an accusation of misconduct, but a compilation of the potential problems found in 22 different papers by this group. I welcome the authors removing any concerns by providing the original figures.

Northeastern University professor with 69 papers on PubPeer has resigned

A chemistry professor at Northeastern University in Boston, MA who has almost 70 papers flagged on PubPeer resigned yesterday, May 4, 2021.

On his blog For Better Science (Update May 5, at the bottom), Leonid Schneider shared an email from the Chair of the Department of Engineering, which states that Thomas J Webster has resigned from the university.

Webster has 69 papers flagged on PubPeer, mostly for concerns about image irregularities. I reported 59 to the journals and institution in March 2020.

Similar images from the Technion

The Technion-Israel Institute of Technology is the oldest university in Israel, ranking itself ‘among the world’s top science and technology research universities’.

It is here that a group of researchers appears to have been publishing remarkably similar photos for the last decade — or more.
