Part of that housing crisis, he said, stems from Purdue University's tuition freeze. "It's a marketing gimmick. It's not a real approach to student affordability," Sanders said. "In order to pay for it, the universtiy ended up cutting in-state scholarships" www.jconline.com/story/news/l...

Gun violence is bad. Free speech is good. PROVE ME WRONG!

Weird juxtaposition. "Croce also lost a defamation lawsuit against critic David Sanders (Purdue University) who was quoted in Times article/Judge:“discovery has proved existence of about 30 instances of fabrication or duplication” in Croce’s research papers." www.visiontimes.com/2025/09/17/t...

A Cuban article on Carlo Croce @OhioState . It doesn't get all the facts correct, but it does include an image of @smutclyde.bsky.social @thatsregrettab1.bsky.social @forbetterscience.bsky.social @elisabethbik.bsky.social www.juventudtecnica.cu/articulos/fr...

David Sanders, an image expert and biologist at Purdue University who weighed in on the images in our previous story, told us from his experience, “when one finds egregious problems in one article it is probable that other articles from one or more of the authors also violate scientific norms.”

More true than ever. @forbetterscience.bsky.social

“Speed is essential, but it’s never too late to take appropriate action,” he says, recalling that “post-publication peer review is just as important as pre-publication peer review, and at least as good.” @forbetterscience.bsky.social

"It seems that the scientists at the NASA Astrobiology Institute remain in denial about the fact the infamous paper & the associated coverage was a tale of catastrophic failure in the institution of science at essentially every level." @forbetterscience.bsky.social

Another retraction from DRG. @forbetterscience.bsky.social

Retraction from Douglas R. Green, former editor of Oncogene, and BFF of Carlo Croce. @forbetterscience.bsky.social

I was recently notified about the following retraction by a friend. It joins another recent retraction from one of the authors, Douglas R. Green, @stjude.bsky.social and numerous corrections (image duplication, etc.) www.pnas.org/doi/10.1073/...

A fair amount of interest in this article. @forbetterscience.bsky.social

“Purdue has created this situation by massively increasing the student population, by having insufficient housing and parking for the people on campus, and by now cutting its support for public transportation,” Sanders said. www.purdueexponent.org/city_state/p...

Finally, an expression of Editorial Concern for two IOVS articles about which a number of us have been concerned because of image cloning iovs.arvojournals.org/article.aspx... Persistence pays.

"But image expert and sleuth David Sanders told us the addendum is “inadequate in multiple senses.” While the correction applied to two proteins, the “problematic” data involve the expression of a third, he said."

“The argument that an image concerning protein expression somehow justifies thoroughly flawed images of RNA levels is absurd,” Sanders said. “extent & nature of the problems with the figures would,in my opinion, dictate that the article should have been retracted" retractionwatch.com/2025/08/25/n...

David Sanders: "This approach to immigration from the government is "a waste of resources that has been placed into (ICE) instead of into social services," he said. "We need to understand the vicious and racist nature of these detentions and deportations." www.purdueexponent.org/campus/gener...

It's been a busy week. After @retractionwatch.com receives a tip, I confirm plagiarism of a hoax & expand the investigation to other articles.“The overlap in the images otherwise is so extensive as to be impossible to represent different patients,” They like my use of the word "irrefragably."

the authors were aware of the problem,as illustrated by data in a supplementary table in their paper. But they were so enamored of their hypotheses that they wished it away&doubled down on the rigor of both their results&their interpretation of them www.timeshighereducation.com/depth/arseni...

“It had nothing to do with the shadow biosphere. It had nothing to do with life on other planets, and it had nothing to do with reality,” he said."

"Purdue University biologist David Sanders said he heard the news on NPR. This was his area of expertise — he’d done work in the relevant area of biochemistry, so he was eager to look into it. He told me he found a fatal mistake in the scientific paper. www.bloomberg.com/opinion/arti...

“It’s the people who are contaminating the literature, and the journals and institutions that are not taking adequate responses” who are undermining science, says Sanders. “Not the people who are authentically digging up problems in the scientific literature.” www.nature.com/articles/d41...

As I said previously, "Some people have a hard time understanding the criteria for retraction and have psychological challenges that prevent them from acknowledging the truth." retractionwatch.com/2025/07/24/s...

Sanders said a retraction of the paper“was always warranted if “a fundamental error undermines a substantial part of an article or a major conclusion.”"the case demonstrates the importance&quality of postpublication review: “Timeliness is critical,but it is never too late to take the proper action.”

“The problem was not that later research undermined the conclusions,” Sanders said. “The problem was that the evidence presented in the article was not supportive of the conclusions from the start and that all the results were based on the fact that the arsenate was contaminated with phosphate.”

"Many scientists, including David Sanders, a biologist at Purdue U, who has previously argued for the paper’s retraction in posts for Retraction Watch, believe the paper’s results were simply the result of contamination of the authors’ materials. He told us he was “glad” to see the retraction"

It appears that Karoline Leavitt needs a course in ethics. Fake citations are not "formatting issues." They are a form of fraud. They are not "#GoldStandard #Science." They represent a falsification of the literature, a type of misconduct. #Liars and #Hypocrites

Karoline Leavitt: "I understand there were some formatting issues [actually fake citations] with the MAHA report. But it does not negate the substance of the report, which...is backed on good [i.e. imaginary/nonexistent] science that has never been recognized by the government."

I wish to thank @retractionwatch.com for the opportunity to participate in the retraction process.
