"In 2024, UNICEF and partners . provided treatment to 36,254 children [under 5] with wasting, including 6,872 with severe wasting" in Gaza. In 2025, "UNICEF and partners . treated nearly 100,000 children with wasting . 19,000 children were treated for severe wasting" in Gaza. Unforgivable.

1/ Initial reactions after some hours with this groundbreaking result proving the NP-hardness of poly-approx CVP/NCP: It is most likely correct, but more importantly, it is original, elegant, and beautiful! (Also: it is easy to improve, quantitatively.) openai.com/index/ten-ad...

Ten advances in mathematics and theoretical computer science

OpenAI shares new results on long-standing open problems in mathematics and theoretical computer science, including advances in geometry, cryptography, and complexity.

"We're all worried," as what it means to do research (in my field, Theoretical CS) seems to be shifting, and shifting fast. What to do? Senior researchers must lead by example, knowing that not everything will pan out. What I'm suggesting below may not work everywhere, but here's my own advice: 1/

Some initial thoughts, and a complicated mix of feelings. Wow. I mean, Erdos problems are cool (I genuinely mean that), I didn't know about the Jacobian conjecture before it got disproved. But this newest batch from OpenAI hits home in a way the previous announcements did not.

150,000 marched yesterday in London for trans rights. Opened the Sky News app. Scrolled and scrolled. Nothing. BBC News app. Nothing. Guardian app. Nothing. This is what actual silencing looks like.

A really good mathematician told me Anthropic is paying people like him $250/hour to improve Fable by throwing hard math problems at it. They also get a separate account where they can use Fable for their own purposes. They can do it for 5 months maximum.

Over the past year, I've had the honor to work with the European Commission to help them understand Google's (terrible) approach to sharing anonymised search data with competitors under the Digital Markets Act, and design an alternative solution that preserves more utility. [1/3]

Ninety percent of the 71 detainees contacted in the concentration camp on Fort Bliss say they were beaten by guards are witnessed beatings, in addition to inedible meals and lack of access to medication or lawyers.

Report: Detainees at ICE facility in Texas report frequent beatings and other human rights abuses

A new report from human rights advocates says 90% of detainees interviewed at a sprawling ICE facility in Texas say they were either beaten by guards or witnessed others being beaten.

I am looking for a blog post that was shared here some time ago. It was by a mathematician who wrote to a canned food company, notifying them that their cans didn't minimize surface area given their volume. The company responded with reasons. Does anyone remember this? Does anyone have a link?

Also, I should mention how nicely theory and practice come together here. The practical application very much needed the theoretical space lower bound that Stefan Walzer and Stefan Hermann proved, so that we can target 1.5x that as a default space usage, rather than just guessing.
