In June, we reported on a retraction in Current Biology that came after a number of PubPeer commenters suggested that the authors had engaged in figure manipulation, memorably comparing watching the published videos to playing the old-school arcade game “Space Invaders.”
Now a second paper from the same team has been retracted from Biology Open after the authors “were unable to repeat the results.” The journal was unable to get in touch with first author Livana Soetedio, whom the University of Illinois at Chicago found had fabricated the data and images in both publications.
A paper by a former postdoc at MD Anderson Cancer Center who “admitted to knowingly and intentionally falsifying” a figure has been retracted.
In August, the Office of Research Integrity announced that it had sanctioned Jun Fu for faking data in a study of the results of a mouse study of NVP-HSP990, a Novartis compound designed to fight brain tumors. Here’s the notice for the study in question, published in Cancer Research:

Harvard stem cell researcher Doug Melton got a lot of press last year for research on a hormone he named betatrophin, after its supposed ability to increase production of beta cells, which regulate insulin.
Now, the conclusions from that paper, which has been cited 59 times, according to Thomson Scientific’s Web of Knowledge, have been called into question by research from an independent group, as well as follow-up work from the original team.
The interest was driven by the hormone’s potential as a new treatment for diabetes. In 2013, Melton told the Harvard Gazette that betatrophin could be in clinical trials within three to five years. Here’s Kerry Grens in The Scientist: Read the rest of this entry »
Here’s the notice that will appear for “Human renal stem/progenitor cells repair tubular epithelial cell injury through TLR2-driven inhibin-A and microvesicle-shuttled decorin“: Read the rest of this entry »
Former University of Tokyo researcher Shigeaki Kato has notched his 26th, 27th, and 28th retractions, all in Nature Cell Biology. The three papers have been cited a total of 677 times.
We reported last week on a Portuguese group that lost two papers over mislabeled image files.
Now, we’ve learned that first author Christian Ramos has been fired after speaking to Retraction Watch and offering what seemed like a heartfelt apology (which you can read here). Read the rest of this entry »
The former director of the X-ray crystallography lab at the National Institute of Arthritis and Musculoskeletal and Skin Diseases, part of the National Institutes of Health, faked findings in three papers, according to the Office of Research Integrity.
Two of the three papers by Bijan Ahvazi were published in 2004, and later retracted in 2007, while the other was rejected: Read the rest of this entry »
The paper has been cited at least once since the lies came to light, as we reported earlier this month.
The journal contacted the relevant parties on October 29 with the following email about “Degradation of 2,4-dinitroanisole (DNAN) by metabolic cooperative activity of Pseudomonas sp. strain FK357andRhodococcus imtechensis strain RKJ300,” although no notice has been posted: Read the rest of this entry »
PubPeer leads the way again: The authors of a paper about Parkinson’s disease in the Proceedings of the National Academy of Sciences (PNAS) have retracted it, several months after a commenter highlighted the exact issue that led to the article’s demise.
The paper, originally published in September 2013, was called into question by a commenter on PubPeer in July 2014, who identified two of the paper’s figures as duplications: Read the rest of this entry »
