Delighted to see @Vaseem_S0's work finally in print @PNASNews.
I'll try to explain the story behind this work in a š§µ below... [1/18]

I spoke with The Daily about whatās happening to math in the age of AIāand what it feels like to be a mathematician right now.
The conversation went places I hadnāt expected.
Iām grateful to @RachelAbramsNY, @annieminoff, and their team.

A hill I will die on: there is no Nobel prize in economics. There is a prize to celebrate the anniversary of a bank.

In January, I reviewed a Review for a crappy MDPI journal.
It was 100% AI, missing citations, etc. I sent a massive report, and the authors withdrew it.
Today, I see it published without a single change in another even crappier MDPI journal.

This person has published 71 papers in 143 days so far in 2026. That is, 2 days per paper (source: Google Scholar).
It's truly amazing. To see someone proud of this.

Science is about to get absolutely nuked.
Unless we get extremely strict about providing and opening up code and data and documenting lab experiments rigorously, a torrent of credible-looking but fraudulent papers is upon us.
Can water intake prevent Alzheimerās disease? No. This is fully AI-generated⦠but the data below could easily pass as real.
The new ChatGPT image model is truly impressive, but I think it poses a real risk for scientific integrity in future.
For example, I could just generate a dataset with a single prompt that appears to show something like water preventing Alzheimerās disease. Ironically, we used to laugh at obvious āAI slopā (like those weird generated mice), but thatās changing pretty fast. If I were reviewing this fake figure today, Iām not sure I could reliably tell whether this figure is real or AI-generated?
The bigger issue is that the usual signals we rely on e.g., how realistic or plausible something looks are no longer enough.
I think we really need more comprehensive AI detection and, more importantly, stronger verification standards for scientific submissions going forward. Weāll probably also need better ways to digitize lab notebooks and ensure access to raw data, something closer to how code and version history are tracked...

Organisms often swim through inhomogeneous environments, such as viscoelastic fluids, where gradients in viscosity and elasticity may arise.
A new Letter shows that spatial variations in fluid relaxation time induce durotactic behavior in active particles.

The Society of Rheology is sad to announce the passage of 1994 Bingham Medalist Professor Andreas Acrivos. Prof. Acrivos and his numerous students and colleagues have made impactful and lasting contributions to rheology theory and practice.

Who reviewed this paper?
A few days ago @gcabanac tweeted about a paper that had published a remark that it had been forced to cite irrelevant papers. You can see the tweet here: buff.ly/3UMIguf. We remarked that if it was not so serious, it would be funny.
Since reading that tweet, we have not been able to get it out of our head, so we thught that we would document it in a little more detail. We are doing this for three reasons.
1ļøā£ In our view, it descerves more detail to be made available.
2ļøā£ We'd like these details to be be kept as a matter of public record, so we are posting similar posts on our X account and our LinkedIn account.
3ļøā£ It should be of interest to this community, so we hope that this raises even further the ethical issues around this topic.
The first image shows the paper that we are looking at. What is interesting is the text that appears on at the end of the introduction (highlighted in red). This appears to show that the reviewer insisted that a set of 13 papers be cited, else they would not accept the paper. It would be interesting to see the review repport, so that we could be certain what had been said. If you want to see the paper, it is available here: buff.ly/4fndXm0
In the rest of this š§µ, we show the papers that have been asked to be cited (i.e. [35]-[47]). These have been taken from the paper mentioned above. You'll notice (as we have highlighted it) that every paper is "et al." meaning, of course, that there are quite a few authors on each paper.
Gicven that we cannot see all the authors, the other images on this š§µ shows the full set of authors on each of these 13 papers.
We leave it an an exercise for the reader to hazard a guess as to the reviewr is?

By issuing "Corrections" without doing investigation, the publishers are in effect laundering fraud into the literature, cementing misinformation and justifying the existence of papermill and other fraudsters. One could argue that such corrections are worse than fraud.
We have to do something about this. Sooner, rather than later. The public will lose trust in science and thenā¦
And weāll kick ourselves for letting this madness go on unhindered.
Last author has WELL OVER 100 papers (most not reviews) in 2024. You know how to do that? Well, you just have to be willing to say :We really apologize for this mistake" and chop off the peaks that the mouse lady doesn't like, and Elsevier will ensure nobody talks about it again. doi.org/10.1016/j.ijhydene.2ā¦

SĆ©bastien Michelin and I would like to advertise the immediate opening of a PhD position at LadHyX (Ćcole Polytechnique, France) in joint supervision with UBC (Canada).
The project will focus on microswimmers in density gradients with a specific emphasis on theoretical analysis and simple numerical modeling of the individual and collective dynamics of microswimmers in stratified media, and its implication on mixing.

My new article is out.
The problem isn't that academic scientists sometimes lie. The problem is that their peers don't care when they do. When scientists are caught making up fake data, universities sweep it under the rug. There are too many examples at the top. 1/
Academia is not just bloated or out of touch, it is committing outright scientific fraudāfake data, doctored images, and allāand normalizing it by not naming and punishing culprits.
Science is in danger.
