Opinion | Science Has a Nasty Photoshopping Problem:

One evening in January 2014, I sat at my computer at home, sifting through scientific papers. Being a microbiologist, this wasn't unusual, although I certainly didn't expect to find what I did that night.

These particular papers were write-ups of medical research, with many including photographs of biological samples, like tissue. One picture caught my eye. Was there something familiar about it? Curious, I quickly scrolled back through other papers by the same authors, checking their images against each other.

There it was. A section of the same photo being used in two different papers to represent results from three entirely different experiments.

What's more, the authors seemed to be deliberately covering their tracks. Although the photos were of the same sample, one appeared to have been flipped back-to-front, while the other appeared to have been stretched and cropped differently.

Although this was eight years ago, I distinctly recall how angry it made me. This was cheating, pure and simple. By editing an image to produce a desired result, a scientist can manufacture proof for a favored hypothesis, or create a signal out of noise. Scientists must rely on and build on one another's work. Cheating is a transgression against everything that science should be. If scientific papers contain errors or - much worse - fraudulent data and fabricated imagery, other researchers are likely to waste time and grant money chasing theories based on made-up results.

But were those duplicated images just an isolated case? With little clue about how big this would get, I began searching for suspicious figures in biomedical journals.
