Potential figure manipulation with corresponding author uncontactable


A reader contacted the journal to raise concerns about a paper containing a potentially manipulated figure. The editor-in-chief agreed with the assessment that the figure had been manipulated and attempted to contact the corresponding author, without response. Following further contact with the co-authors and institution, it was established that the corresponding author had retired after publication of the paper, and no current contact details could be found.


Data manipulation and institute’s internal review


A journal received an enquiry from a reader stating that they had found some discrepancies in the spectra published in the electronic supporting information for a published paper. They suggested that the discrepancies would be consistent with the spectra being manually ‘cleaned’. If this were true, the characterisation and purity of the compounds reported in the paper would be called into question.


Handling self-admissions of fraud


In November 2014, the first author of a decade old paper in our journal and a 15-year-old paper from another journal informed us that he faked the data in two figure panels in the paper in our journal and one figure panel in the paper in the other journal. The main gist of the manipulation was loading unequal amounts or delayed loading of gel lanes.


Suspected image manipulation involving four journals


Editorial office staff at journal A noticed possible image manipulation in two figures of a new paper submitted by author X. These suspected manipulations involved images of gels which appeared to contain multiple duplicated bands. This prompted editorial staff to look at the submission history of author X to journal A in more detail.


Image manipulation as a general practice


As managing editor, I view all manuscripts before they are assigned to an editor. Within a 4 week period, I have detected five manuscripts where photographs of either gels or plant materials were used twice or three times in the same manuscript. These manuscripts were immediately rejected.


Publication of data without permission


A director of an institute in France has expressed concern about a paper published in our journal. One of the authors (not the corresponding author) of the paper, person A, visited his laboratory in France for 5 months in 2009 to carry out some work. The director says that some methods used and results obtained in his laboratory have now been included in the paper without his knowledge or permission.
