The fall of a prolific science journal exposes the billion-dollar profits of scientific publishing
One of the 15 publications that put out the most studies globally has been expelled from the indexing system for irregularities. Its publisher, Elsevier, has a 38% profit margin that reached $1.5 bill...

It is such a delight to see a stream of new MathML upgrades!
For this holiday season, should we make all of our exponents into animated lights? 🎄

SocArXiv has had enough of AI papers. Requires acceptance of those papers first. Exceptions are made for studies of the effects of AI in society.
1. Pausing new submissions about AI topics for 90 days. That is, papers about AI models, testing AI models, proposing AI models, theories about the future of AI, etc. We will make exceptions for papers that are already accepted for publication (or published) in peer-reviewed scholarly journals

Wow! Yuansi Chen resolves 1 of the 2 remaining $1000 Talagrand problems (michel.talagrand.net/prizes/prize... ):
If you take any f : {-1,+1}ⁿ → ℝ⁺ and apply the noise operator T_{.99}, the resulting function g = T_{.99} f satisfies a better-than-Markov inequality. That is, Pr[g > t E[g]] < o(1/t).

Today when trying to figure out how to write some alt-text for a professor's image of a math equation, I found out about MathML. It is so cool! A standardized, markup language that makes math equations appear correctly (and accessibly) natively in most browsers without needing LaTeX plugins.

Image screening is going to fail. We need audit trails for data provenance.
I tried an even harder example on Gemini Pro image generation and this is quite scary/amazing. I asked for a microscopy image of around 20 HeLa cells, GFP tagged 20% nuclear, 10% membrane, +1 nuclear staining, + overlap. Image below and prompt in the following post.

“lazy use of unwrap blew up a process and took out the internet” bzzt. wrong. judicious use of unwrap blew up a process instead of allowing an Extremely Named CVE to happen and spraying your bank account credentials all over the public internet
People want a technical solution to what is ultimately a judgement problem.
People know that unwrap can cause a panic. That's the choice that's being made when you unwrap. Changing the name won't change that.

🚧 OSF experienced a temporary slowdown today due to a surge of automated bot traffic. This overwhelmed parts of the production environment that didn't yet have the right safeguards in place, causing performance issues. The underlying issue has been addressed, & further protections are now in place.
