El Niño/La Niña famously cannot be reliably predicted more than ~6 months in advance due to the "predictability barrier": this is a chaotic system! New research from Australia (CSIRO/UMelb) just showed it *can* sometimes be predicted much earlier, up to a full year! www.science.org/doi/10.1126/...

Also, I don't know if there is any way to be clearer, but: If you are a theoretical computer scientist or mathematician currently working for OpenAI, you are not one of the good guys.

Interesting looking paper on what you can and can't identify from staggered adoption panel data. Also, I move that all important equations get subtitles:

We had some fairly big updates to tidymodels.org this year. I'm gonna post about them this week! The first thing you might have noticed already is that we now have a dark mode on the website! Every page and element should now work both in light and dark mode! #tidymodels

Hm. Honestly a bit bewildered by the choice. "And I know how to read a research paper." Reading a scientific paper isn't the expertise required to build real trust by translating, visualizing, critically assessing what's actually happening in practice for laypeople www.statnews.com/2026/09/21/t...

AI models tend "to resolve cross-linguistic disagreement by treating the English judgment as authoritative, rather than acknowledging the cross-linguistic inconsistency of human language." What's the problem with that, and what should be done about it?

these pointless chatbots are what journals are literally spending our tax money on because these publishers are leeches off the public purse and then fence off academic outputs into weird systems also Maxwell / Epstein money

Inclusion is often conditional with "a hidden cost of fitting in" and facing "an unspoken expectation to adapt: to align with dominant norms of speech, behaviour and self-presentation" + creating "distance between who people are and how they feel able to present themselves" that erodes confidence.

If real love is caused by who the beloved is, *and* should persist, what—if any—changes in the beloved might relax the latter expectation? Cool research by Mikalonyte et al finds a hierarchy: morals > memory > physical appearance … buff.ly/YSrNOlu 1/2

God, this is scary. They are killing science in universities and are pretty open about that. What’s unclear is whether they honestly think this is good for science, or consider it to be acceptable collateral damage of hurting universities, or don’t care as long as it funnels money to corporations.

For decades we hear women have smaller brains therefore we're stupid (yes, look up the great term for this "neurosexism") — but now it's "crows have a small brain therefore they are smart"? We're winning and have a murder on our side, I guess. Cool.
