A cloud of doubt has descended over the work of a former Australian science agency researcher, with two papers retracted and a third under scrutiny. This situation underscores the critical importance of data integrity in scientific research. Let's delve into the details.
At the heart of the matter is Benjamin Mayne, a molecular ecology researcher formerly associated with the Commonwealth Scientific and Industrial Research Organization (CSIRO) in Australia. His work, focusing on using DNA methylation as an 'epigenetic clock' to predict the age of various animals, has come under fire.
Two of Mayne's papers, published in Molecular Ecology Resources, have been retracted. The first, released in June 2021, aimed to estimate the ages of three threatened fish species. The second, from April 2022, proposed a similar clock for sea turtles. These papers have been cited 41 and 32 times, respectively, according to Clarivate’s Web of Science, highlighting their initial impact on the scientific community.
But here's where it gets controversial... Co-authors raised concerns about data issues. Specifically, Simon Jarman, a researcher at Curtin University, pointed out that the results in a figure were inaccurate and did not represent a real relationship between age and DNA methylation. Mayne agreed to the retractions, as stated in the retraction notices.
Ben Creagh, an executive manager at CSIRO, confirmed that Mayne is no longer with the organization and that CSIRO is conducting further inquiries.
Adding to the complexity, a third paper, where Mayne was a co-author, received an expression of concern on October 16. This study, published in July 2024, focused on estimating the age of seabirds. Lead author Lauren Roman raised concerns about potential inaccuracies in the data, suggesting the study might not be reproducible. Roman, affiliated with CSIRO and the University of Tasmania, declined to comment further. The institution is investigating the matter, but Wiley, the publisher, has not confirmed which institution is involved. This raises questions about the scope of the investigations and their potential implications.
And this is the part most people miss... In July 2024, the South Australian Genomics Centre announced Mayne as the senior genomics research coordinator at Flinders University. However, he left this position in January of this year. His current affiliation remains unconfirmed.
This situation prompts some critical questions: What safeguards can be put in place to prevent such issues in the future? How can we ensure the accuracy and reliability of scientific research, especially when it comes to groundbreaking techniques like epigenetic clocks?
