Densitaxis! https://t.co/4d1nPt6XVp Delighted to see @Vaseem_S0's work finally in print @PNASNews. I'll try to explain the story behind this work in a 🧵 below... [1/18]

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. https://t.co/JwmBIyrynM

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: https://t.co/xke2cnDxwh. We remarked that if it was not so serious, it would be funny. Since

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 then… And we’ll 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.

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 fraud—fake data, doctored images, and all—and normalizing it by not naming and punishing culprits. Science is in danger. Read the new article by @benlandautaylor here:

Turbulent flows have been used for millennia to mix solutes; a familiar example is stirring cream into coffee. However, many energy, environmental,...
Excited to release our latest work, led by @CBrowneSciClown: https://t.co/5KA62kERbG! Here, we introduce a simple, robust, versatile, & predictive way to mix fluids in porous media—where slow diffusion in laminar flows typically limits mixing. 🌪️💧 Tweetorial follows... [1/6]

However, we do know that global warming is heating up the earth and this is also causing increasing stratification of bodies of water. And so it is crucial to understand what ecological effects increasing stratification will have. [17/18]
