As part of his job as fraud detector at biomedical publisher Spandidos, John Chesebro trawls through research papers, scrutinising near identical images of cells. For him, the tricks used by “paper mills” — the outfits paid to fabricate scientific studies — have become wearily familiar.
They range from clear duplication — the same images of cell cultures on microscope slides copied across numerous, unrelated studies — to more subtle tinkering. Sometimes an image is rotated “to try to trick you to think it’s different”, Chesebro says. “At times you can detect where parts of an image were digitally manipulated to add or remove cells or other features to make the data look like the results you are expecting in the hypothesis.” He estimates he rejects 5 to 10 per cent of papers because of fraudulent data or ethical issues.
Spandidos, based in Athens and London, accepts a large volume of papers from China, with around 90 per cent of its output coming from Chinese authors. In the mid-2010s, independent scientists accused Spandidos of publishing papers with results that recycled the same sets of data. As part of its response to the allegations, the publisher is using a team of in-house fraud detectors to weed out and retract fake research.
Over the past two decades, Chinese researchers have become some of the world’s most prolific publishers of scientific papers. The Institute for Scientific Information, a US-based research analysis organisation, calculated that China produced 3.7mn papers in 2021 — 23 per cent of global output — and just behind the 4.4mn total from the US.
