Concerns about Marseille’s IHUMI/AMU papers – Part 3

This is Part 3 of a series describing papers from the Institut Hospitalo-Universitaire Méditerranée-Infection (IHUMI or IHU) and Aix-Marseille Université (AMU) — institutions in Marseille, France — with potential problems.

In Part 1, I listed papers with image concerns. In Part 2, I focused on a set of papers describing many different research projects on specimens collected from homeless people — but all run under the same IRB approval number.

In this post, we’ll take a look at IHU/AMU papers describing samples obtained from people in African countries. Many of them lack wording on ethical approval by the local authorities, and all lack authors from these countries. This type of research might fall under the definition of neo-colonial science.

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.

Concerns about Marseille’s IHUMI/AMU papers – Part 2

This is part 2 of a series describing papers from the IHUMI/AMU institutions in Marseille, France, with potential problems. In Part 1, I listed papers with image concerns. In this follow-up I’ll focus on a set of papers that might have problems with human subjects research not having received proper ethical approval. The articles span a decade of research on homeless people in Marseille, and involve different studies and specimens — but all were run under just one IRB approval number.

Cassava Sciences: Of Posters and Spaghetti Plots

In a previous blog post, I took a look at Western blots in papers from the lab of Dr. Hoau-Yan Wang at City University of New York (CUNY), mostly related to Cassava Sciences (Nasdaq: $SAVA), its predecessor Pain Therapeutics INC, and its flagship Alzheimer’s Disease drug candidate Simufilam.

While those papers were mainly about the preclinical Simufilam data, here I will review a conference poster reporting on Phase 2 data obtained by Cassava Sciences.

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.

Impersonators and fake email addresses

This morning a professor at a US university warned me that they had gotten an email from a person pretending to be me. The email came from elisabeth_bik@yeah.net, and was signed with my name. But that is not my email address!

The email sent to the professor flagged a scientific paper as “The following article is fake. The impact on society is very bad”.

Maybe I should feel flattered, but it is quite disturbing that people pretend to be me.

So here is a quick warning that there are Elisabeth Bik impersonators using fake email addresses. My correct email address is eliesbik at gmail dot com and if an email comes from any other address that is not me!

Update January 2022:

Several other fake email addresses have been reported over the last months. I will list all of them here and update if needed. None of them is me!

The Hot-Crazy Matrix paper

Lots of buzz yesterday on Twitter about a paper already published online a year ago, but assigned to the February 2021 issue of Personality and Individual Differences, an Elsevier/Science Direct journal. The paper builds upon a popular — but not scientific — YouTube video in which men are advised to only date women who are “hot and not too crazy”, and women are believed to only want to marry rich guys.

Figures 1 and 2 of the paper — taken from this video but without giving credit — are presented in this paper as scientific data. Of course, I have concerns.

Springer and the Double Dip

A quick post after stumbling upon a paper that got retracted years ago, but the publisher isn’t going to tell you. Springer still charges $40 (plus tax) to read the retracted paper itself — then will happily charge you another $40 for selling you the retraction notice.
