Is science self-correcting? Not in this Elsevier journal.

Around 2014-2015, I screened 20,000 biomedical articles for image duplication in 2014-2015. About 4% of those papers, 782 to be exact, contained inappropriate duplications. Together with my coauthors Arturo Casadevall and Ferric Fang, I published that work in mBio in 2016 here.

Unfortunately, many of these problematic papers are still not addressed by the journals now, ten years later, even though the concerns in some of them are far beyond what could be blamed on an innocent error. Two of those examples were published in Cytokine, a journal that seems to care little about the problematic papers they published in the past.

COVID-19-vaccine-induced eye damage? Reused images, impossible demographics, and an incomplete ethics approval number

A 2025 paper published in Ophthalmic Epidemiology is being promoted online as proof that COVID-19 vaccines damage the eyes. Before accepting that conclusion, it was worth looking at the paper itself.

A closer look at the article revealed a reused figure published by another group of authors, 59 men plus 69 women in a study of 64 participants, no control group, and an ethics approval number that seems generic and incomplete.

UnEDXpected Peaks

Over the past couple of days, I have been reviewing a series of Materials Science papers, all co-authored by the same group of researchers from the Universities of Lahore, Chakwal, and Sargodha in Pakistan. While reviewing them, one analytical technique kept standing out for unusual reasons.

Peer Review Congress Chicago – Day 1

It’s Peer Review Week! A perfect time to post my notes from the 10th International Congress on Peer Review and Scientific Publication, which was held at the Swissôtel in Chicago, two weeks ago, September 3-5, 2025.

This was my first time attending this congress. I tried to live-post all the talks on BlueSky [except for one session where I sneaked out].

You can find most posts about this conference under the hashtag #PRC10 on BlueSky or X. Andrew Porter @retropz.bsky.social, Research Integrity and Training Adviser at the Cancer Research UK Manchester Institute, created a BlueSky feed as well.

This post will contain (lightly edited) notes from Day 1. Click here to see the posts from [Day 2] and [Day 3].

ScienceGuardians, where disgruntled authors complain about PubPeer

On Twitter/X, @SciGuardians, associated with the website ScienceGuardians.com, is promising to ‘uncover’ some big conspiracy of fraudulent @pubpeer.com users.

But in reality, the account appears to be run by one or more disgruntled scientists with dozens of problematic papers. And there is no big reveal.

New ORI regulations

The US Office of Research Integrity updated its regulations on handling research misconduct allegations. Key updates include clarifying the inquiry process and adjusting how institutions should handle the allegations and record the process.

1 in 7 scientific articles might be fake

James Heathers published a preprint arguing that the old, often-cited number that 2% of papers are fake is outdated and a vast underestimate. In a new preprint, he argues it might be 1 in 7 papers, based on 12 studies that together analyze 75,000 scientific articles.

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]:

  • spreadsheet with the 28 29 papers found with PubPeer links [Excel file]
  • slide deck with the 58 59 image problems found in the 28 29 papers [PDF].

Problematic Papers from Zhejiang University

This post describes a set of over 20 papers with mostly image problems from the Department of Pharmacology at the School of Medicine of Zhejiang University in Hangzhou, China. All papers have Professor Ximei Wu as the common – and often corresponding – author. The Wu lab conducts research on stem cell and bone development, and their papers contain many images of Western blots and immunohistochemistry experiments.
