Who is draining Africa? This figure shows net-appropriation of resources from Africa's CFA zone, illustrating two key facts. 1) Eurozone countries are the biggest appropriators, benefitting from the Francafrique system. 2) Contrary to conventional Western narratives, China's appropriation is tiny.
Here's Amazon's two new planned fossil-fuelled AI data centres next to the ENTIRE POWER GRIDS OF SEVERAL LARGE COUNTRIES Together, the two gas-burning data centres will emit more than Spain's entire grid, if built
Looks like a null effect of TUS on LGN using a very sensitive measure (SSVEPs) by a top vision science group. More reason to be careful interpreting TUS results

It's the unseriousness of the whole thing that gets to me. What is produced as scientific research in one of the top business schools in the country. What they measure and what's being reported have nothing to do with each other. How do they not feel ashamed to circulate this report? (rhetorical)

Bitte nicht korrigieren oder erklären, ich habe mich null informiert und es interessiert mich auch nicht.
This is what makes it art: '(...) the publisher posted a blank white page with the cryptic phrase, “This article has been withdrawn due to article violation.” Springer Nature is nevertheless still selling the empty PDF for $39.95.' www.science.org/content/arti...
Why have papers by one of history’s most famous physicists been retracted?
Springer Nature has removed two studies by Max Planck. A bot may be to blame

A Ukrainian drone dives lazily through Moscow skies to strike an oil refinery in the SE of the Russian capital earlier on June 16. The refinery, 16km from the Kremlin, provides a large proportion of Moscow and its region's fuel needs, Ukrainian news sources say. Russia's fuel crisis set to worsen.
Our Bluesky discussion on data sharing in the genAI era is famous
My latest for @nature.com looks at the challenge researchers are facing thanks to bots scraping their data uploaded alongside their research - and what they think ought to be done about it www.nature.com/articles/d41...
This is amazing. They actually quantified the tetrahedral color and color perception of hummingbirds. www.pnas.org/doi/10.1073/...
And finally it was published! Massive thanks to my coauthors, the editor and reviewers, and the institutions that supported our research. journals.plos.org/plosone/arti...
What did the dove sing to Pope Gregory? Ancestral melody reconstruction in Gregorian chant using Bayesian phylogenetics
An attractive goal in the study of Gregorian chant melodies is reconstructing unobserved melodies as they may have been transmitted along their history, especially as early chant notation does not cap...

What did the dove sing to Pope Gregory? A thread on phylogenetics and cultural evolution featuring our new preprint with Jan Hajic jr. and Klára Mühlova (www.biorxiv.org/content/10.1...) and previous contributions to the field.
I get a weird, almost physical sensation in my eyes from this image
I know “the personal is political” and “everything is political” but I simply cannot live life being forced to consider everything in a broader context. That’s not cowardice—it’s self preservation
"interesting long read" is how economists say "your identification strategy, it is totally believable, this is causal" and i think that's lovely
Interesting long read from @jburnmurdoch.ft.com making the case that declining birth rates are particularly tied up with the rise of smartphones and therefore fewer people in relationships, which in turn leads to fewer kids www.ft.com/content/fba3...

📣 The difference between replicable and not replicable is not itself scientifically replicable. 📣 New work with Erkan Buzbas, showing that verdicts such as "X% of results replicated" are based on an inferential machinery that doesn't work. arxiv.org/abs/2604.26268
just had my mind blown learning the term “escalate” is derived from the word escalator (originally a trademarked name), and not the other way around
Watching these is what self care looks like 🛀

Time to start a bluesky Christmas fight: Most over-rated and under-rated cuisine? For me: Over-rated: French Under-rated (globally): Mexican Under-rated (US specifically): Indonesian
Many of the most passionate Bayes verses frequentist debates are not between I and II or III and IV but rather I and IV. People are often excited more about the freedom to work with better models than having uncertainty quantification.
