Ian McKellen performs “The Strangers’ Case” speech from “Sir Thomas More” on Colbert.

Self-feedback loops matter. The model drafts, critiques itself, retrieves more context if needed, and refines. Everything is open-source: models, code, data store, and a new benchmark (ScholarQABench). 3/3 www.nature.com/articles/s41...

The citation problem is severe: GPT-4o fabricates 78-90% of citations when asked to cite recent papers. OpenScholar achieves citation accuracy on par with human experts by grounding responses in 45M open-access papers. 2/3

I've always been a fan of what the Allen Institute is doing. New in Nature: OpenScholar, an 8B RAG model for scientific literature, outperforms GPT-4o by 6% on correctness. Experts preferred its answers over human-written ones 51%-70 of the time. www.nature.com/articles/s41... 1/3 🧵

inspired by CLAUDE.md, I’ve started putting markdown files named after coworkers into work code repos so I can remind them to stop doing shit to the codebase that annoys me for some reason they’re all mad at me now, which means ill be adding commands to JEREMY.md for an attitude adjustment

We are advertising for a Lecturer in Physical Oceanography, closing date 31 March. If you have research interests in the shelf seas, estuarine and coastal oceans then this could be for you! And you could do research using UEA's fleet of ocean gliders vacancies.uea.ac.uk/vacancies/20...

🚨 GAMs have moved on—so it’s time for an update. On March 3, 2026 (17:00–19:00 CET) I’ll be livestreaming an updated introduction to Generalized Additive Models in R 📺 YouTube livestream link: youtube.com/live/A9U8e1K... #RStats #mgcv #GAMs #gratia #statistics 🧪

All my #rstats ebooks are now in the quarto format, and hosted on Quarto Pub. Their old bookdown links will all be dead by the weekend. 1/3

Isn’t it about time that European countries tax the shit out of the massive US tech firms looting them (they exploit every loophole to pay relatively little tax)? If he raises tariffs, we raise taxes on their revenue. www.theguardian.com/world/live/2...

How HSE supports Russia's war: trap.org.ua/en/publications/how-the-russian-higher-school-of-economics-supports-the-war-against-ukraine/ HSE seminar series & speakers (incl. many international ones, from top universities): sites.google.com/view/hse-econ-seminar/hse_seminar

While Ukrainians face 30+ hour blackouts, Moscow's Higher School of Economics hosts seminars with top international speakers-then uses the same rooms for drone fundraisers. Academics don't get paid for seminars. So why present at an institution actively funding mass murder of Ukrainians? #Econsky

📈 Registrations now open! Time Series Analysis & Forecasting in R 🗓 20–24 July| 🌍 Online A very hands-on course on dynamic GLMs/GAMs for ecological time series using {mvgam} & {brms}. Bayesian models, nonlinear effects, forecasting & live coding in R. www.physalia-courses.org/courses-work...

Our first symposium of #TIBS2026 explores the exciting field of quantitative #Paleoecology. Discover how #data, #models, and innovative #methods are used to unlock and analyze the extensive ancient ecological record to address important scientific and practical questions.

Ok science hivemind 🧪. I have a distinct memory of an awesome graphic in a paper about how environmental filtering and biotic interactions determine whether an organism can live in any given place. Almost like multiple filter layers on top of another. Does anyone have a preferred graphic of this?

Interested in Species Distribution Modeling (SDM) and Ecological Niche Modeling (ENM) in R? Don’t miss this chance to level up your skills! The course is nearly full — www.physalia-courses.org/courses-work... #SDM #ENM #RStats #Ecology #DataScience

If you mentor scientific writers, teach a course with written assignments, or anything similar, you know how much work is involved, and how difficult it can be to provide the guidance developing writers need. This book is for you! 2/2

Over the holiday, while folks were on well-deserved breaks, our new book was released! Mentoring writers is hard - we can make it easier for you. Please help spread the word - repost this, tell your colleagues, etc. scientistseessquirre... 1/2

I'm teaching Statistical Rethinking again starting Jan 2026. This time with live lectures, divided into Beginner and Experienced sections. Will be a lot more work for me, but I hope much better for students. I will record lectures & all will be found at this link: github.com/rmcelreath/s...

We are recruiting several PhD students. If you are interested in conservation conflicts, population ecology, quantitative ecology, or biodiversity, check these projects out (links in the thread, feel free to reach out):

It's official - my new book is officially published today! If you mentor science students who write - grad or undergrad - you're the reason we wrote this. Mentoring/teaching writing is hard; but we can make it easier!

Here is a little piece about the day of my final Monkey Cage recording - a couple of weeks ago in beautiful #manchester www.bigissue.com/opinion/robi...

Goodbye, Monkey Cage - not as infinite as I imagined

Probably should have been made a month or more ago, but better late than never. Made my mum’s family Christmas cake recipe for the first time since moving to 🇩🇰

A mystery seed from a Breckland, eastern England ghostpingo core as found by @hayleymcmechan.bsky.social. help oh botanists!!! 1 mm scale @annasolcova.bsky.social @jo-the-botanist.bsky.social @bramblebotanist.bsky.social @timholtwilson.bsky.social

Huge thanks to @gsimpson.bsky.social and everyone who joined our GAMs in R course! 🚀 Happy modeling, everyone! 🎉

A palaeoecological plant find from a Breckland ghost ice age pond core (East Harling, E. England). Puzzled over by @hayleymcmechan.bsky.social & myself. Help with ID please team!! Seems obvious but stuck. @jo-the-botanist.bsky.social @bramblebotanist.bsky.social @timholtwilson.bsky.social

We have a preprint about modelling three-dimensional movement tracks, led by @njklappstein.bsky.social. The model takes the form of a step selection function and, just like in 2D, it can include directional persistence, attraction to targets, and habitat selection. doi.org/10.1101/2025...

If you want to see me get flustered, but recover to give a banger talk about RSV prophylaxis, the magic of GAMs, and the vital importance of survellence data, then this is the talk for you. With shout-outs for @gsimpson.bsky.social, @vincentab.bsky.social, and @hpscireland.bsky.social

A new release of the mgcv #RStats 📦 is out on CRAN and Simon Wood (U Edinburgh) has added some significant new features despite the small bump in version number: 🌟 scasm() for estimating GAMs with shape constrained smooths. Can be used with any family & smoothness selection is via the EFS method

Opinion: Chaos is coming for scholarly publishing. Buckling of commercial models alongside maturing of community-led efforts promises major shifts, says Caroline Edwards (@theblochian.bsky.social). www.researchprofessionalnews.com/rr-news-uk-v...

I’m seeing some misinformation about pseudo-random number generator best practices going around the internets. Let’s talk about why the pseudo-random number generator seed you use shouldn’t actually have any impact on your results and, consequently, you can choose whatever seed you damn well please.

So Framework is supporting projects in the Linux ecosphere that are lead by vile, racist, homophonic, transphobic people and sees nothing wrong with that. And Shopify supports and platforms the racist idiot that built Ruby on Rails, all because their money stream is entirely dependent on Rails

Fuck Kramnik

The Pink Book of #MarginalEffects (aka Model to Meaning) ships next week and I've got a backlog of Zoolander memes. Hope you're hungry for some spam in your timeline. #RStats #PyData

The new {marginaleffects} release for #RStats (0.30.0) comes with two new vignettes: 1. Speed up computation with automatic differentiation (often 10x gains) marginaleffects.com/bonus/perfor... 2. Power analyses with {marginaleffects} and {DeclareDesign}. marginaleffects.com/bonus/power....

We're glad to finally bring you this update!

I am beyond excited to announce that ggplot2 4.0.0 has just landed on CRAN. It's not every day we have a new major #ggplot2 release but it is a fitting 18 year birthday present for the package. Get an overview of the release in this blog post and be on the lookout for more in-depth posts #rstats

If you’d like to go beyond updates and truly master GAMs in R, join our online course with @gsimpson.bsky.social, 8–11 Dec. 📊 Learn how to fit, interpret, visualise, and communicate GAMs in practice, guided by one of the leading experts in the field. www.physalia-courses.org/courses-work...
