No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition. Which just makes me want to share it again: www.nature.com/articles/d41...

Russia continues to answer diplomacy with missiles. We are determined to make that choice painfully expensive. Today, we present our 20th sanctions package. Sanctions severely hurt Russia’s economy. And every sanction chips away at its capacity for war. (1/9)

Thoughts from a newbie using Claude Code for the first time. I don’t always use GitHub for my projects, but with Claude Code it feels like a must. Having a tool read and write files without version control is just too scary.

Auschwitz was at the end of a process. We must remember that it did not start from gas chambers. This hatred gradually developed: from ideas, words, stereotypes & prejudice through legal exclusion, dehumanization & escalating violence... to systematic and industrial murder. Auschwitz took time.

Despite the focus on small boats, most refugees stay in poor countries. I went to Sudan, where nearly 1/3 of the population has left their homes, to see how the UN is coping with Trump's cuts and the west's retreat. Sudan is a brutal, forgotten war. Please do read: as.ft.com/r/7db76b9a-8...

Many discussions about 🇪🇺 tech sovereignty. 👇🏻 A fascinating aspect, sometimes overlooked, is the public's behavioral reaction to MAGA: e.g., how many people and institutions will drop PayPal and use Wero? (A coordination problem where every user attracts others.) werotracker.eu

Of the big four 🇺🇸 🇪🇺 🇷🇺 🇨🇳, three are ruled by people who want to increase their empires by force. Do they even notice that the fourth, 🇪🇺, is the only one that is actually growing? Interesting discussion of Greenland in this thread and article.👇🏼

There's A LOT going on right now in struggle b/w democracy & authoritarianism, so it's hard to keep up. But it's going to be REALLY important that we pay attention to (and keep pushing back against) how election lies (from 2020) are being mobilized in ways that threaten election integrity in 2026.

In the 1950s and both were at 50%. This strong trend may contribute to rising inequality. www.nber.org/papers/w34643

The celebration and digital metastasization of conspiratorial thinking culminating with the U.S. head of health and human services believing that and governing as if modern diseases don’t emerge naturally, pandemics are all manmade, and science (not the complexities of nature) is to blame.

"It is going to get so much worse." For the first of two end-of-the-year episodes of @pandemia.bsky.social, I talked to @drdemetre.bsky.social about what happened in 2025 at the CDC and how he thinks about the future of vaccines and public health in the US. A quick 🧪🧵

Übrigens kann man hier auch den Stellenwert des EU Parlaments in der Bevölkerung ablesen. Eigentlich ist das EU Parlament an vielen Stellen wesentlich wirkmächtiger, aber der große diskursive Aufschrei, wie er erfolgte als Merz im Bundestag mit der AfD paktierte, bleibt hier weitgehend aus.

When I was a medical student 45 years ago, I clerked in a 13 year old girl with deep jaundice and an abdominal mass. She was Hepatitis B positive. That had led to a primary liver tumour. In a 13-year-old. She was dead within the month. Avoidable with vaccination.

Brexit should have been a lesson. It's a misunderstanding of sovereignty. Individual countries that are not China or the US have to follow the rules set by major powers as they have no bargaining power. Only together European countries are strong.
