This is one of the most exciting findings in animal welfare science I've seen in a long time: A new paper uses electron beams to create a vaccine that reduces broiler lameness by 50% (!) in a Staphylococcus challenge trial.

New footage reveals pigs suffering in crates in a farm linked to a top 5 US supermarket chain, which promised a decade ago to stop selling crated pork. This should be a national scandal. Yet the media is too timid to even cover it. Only a popular outcry will change this.

A new legal letter aimed at OpenAI lays out in stark terms the money and power grab OpenAI is trying to trick its board members into accepting — what one analyst calls "the theft of the millennium." The simple facts of the case are both devastating and darkly hilarious. I'll

Here's a wild fact that I—as a former New York renter—had not clocked before. Average home prices are actually lower than 2018-9 across much of Manhattan and the posher bits of Brooklyn. Correspondingly, there have been huge increases in suburbia: Westchester, Jersey etc.

Excellent thread from Rob explaining OpenAI's proposal to shift away from its non-profit structure, and the letter (notforprivategain.org/#intro) strongly opposing it

🚨 I4R released my experiment with a new academic-literary form, a “replication opinion.” I made myself judge in a debate and wrote an opinion that is more credible than either party could muster. Piece: econstor.eu/handle/10419/3… Post: davidroodman.com/blog/2025/05/0… 🧵 follows

A few months ago, a paper came out challenging the idea that supply and demand applies to housing. As you'd expect, this was celebrated in NIMBY circles. I have written a short technical comment showing that the paper is seriously flawed. 1/

Excited to be part of this fellowship! I really admire the work Works in Progress and Asimov Press do. I’ll be writing about AI x health & economic impacts - would love to chat about ideas, tips, or pieces you'd love to read.

Some personal news… After 14 years (!) this is my last week at Center for Global Development. More later on what's next, but first a short thread of appreciation for a place which I think is not just special, but indispensable. (This is a bit grandiose, but I'm leaving, so permit me this once.) 1/

This is one of the most enduring and hopeful messages of effective altruism to me—that even in the face of challenging circumstances, ordinary individuals retain the remarkable power to help others.

Cool to see Cari and Dustin highlighted in TIME100 Philanthropy today. They don't toot their own horns much, but they've given over $4b so far - I believe they're the youngest billionaires to have given such a high proportion of their wealth away.

175 million fewer day-old chicks were slaughtered in the egg industry over the last 4 years due to in-ovo sexing The technology is growing extremely fast in the EU; from 2% market share 3 years ago to 26-30% now
