You probably have more experience in the scientific research and publishing world than I do, but my time at research labs at three different institutions working long hours on experiments that mostly don't work out leads me to read these allegations in a very negative light. Photoshopping results is a real affront considering how much failure goes in to actually advancing science.
Not sure if you have read this yet, but Bik goes farther here than with the Daily. A selection of quotes from her and others-
https://www.statnews.com/2022/11/30/stan...ed-images/
Quote:The newly identified apparent manipulation in Cell is especially serious as it seems to alter the results and appears to be intentional, said Bik. “I would testify in court that’s been digitally altered,” she told STAT. “This actually changes everything. … It’s a more severe level of digital altering.”
The image in question is a western blot, which is used to determine the presence of specific proteins in biological samples. The authors claim the results shown in this western blot help demonstrate that two proteins only form a complex in the presence of a signaling molecule, which in turn, is key to supporting the paper’s findings about how these protein complexes guide the direction of the growth of axons, the long, winding projections neurons send out to connect with other neurons.
Rather than simply improving appearances, as some alterations may do, this one “appears to be changing the actual results,” said Bik.
Quote:Paul Brookes, professor at the University of Rochester Medical Center in New York who created a blog to flag signs of scientific fraud, noted that it can be hard to determine when duplication is intentional and when it is accidental. ”But in this case I’m inclined to agree that sections of background appearing to be cloned does not seem to be something that could have occurred accidentally,” he wrote in an email to STAT.
Quote:Bik said she disagreed with Stanford’s defense. “To me, automatically dismissing it is the wrong answer, it doesn’t show to me they care about scientific integrity,” she said. “At some point, you can’t just blame it on an error, it seems to be a pattern.”

“These problems seem to be following him along his career,” said Bik. Even if Tessier-Lavigne didn’t directly create the images, she said, the fact that these issues have occurred on papers he’s involved in alongside multiple teams makes them harder to dismiss as the work of a wayward graduate student.
......
Research labs are often highly hierarchical, and Bik said that, though she did not know details of Tessier-Lavigne’s lab culture, a senior figure who’s repeatedly associated with manipulated images could be creating an unhealthy work environment. “It might suggest there’s an atmosphere he creates in his labs. Maybe intense pressure or an unwillingness to accept a result giving him different results than he wanted. … That’s not an unusual situation,” she said.
OK, let's wait for the investigation to be certain. But for me, on the balance of what's known he should step aside for now.
And I sincerely doubt they will be able to track down the original data for all or maybe even any of these papers, even if it isn't a whitewash. Will be tough to get anybody talking bad about a person who was likely instrumental in advancing their careers and if guilty would besmirch their own reputation. And there is no subpoena power here. Even a very motivated and well resourced investigation, which this does not seem to be, would be tough to reach firm conclusions of who clicked copy/paste or smudge tool etc, and who just didn't notice it.
Even the milder explanations for the image altering in all these papers is a horrible example for all students, postdocs, and professors. So for me, he should step aside for now.
