I wish I didn’t have to share this. But the BBC has decided to censor my first Reith Lecture.

They deleted the line in which I describe Donald Trump as “the most openly corrupt president in American history.” /1

As GFI's @emmaiggie.bsky.social explains, Avian flu outbreaks like the one we're experiencing now are not a fluke — they're a recurring problem that is unlikely to stop until we diversify our protein supply with new, animal-free methods of production. Learn more: www.fooddive.com/news/eggs-bi...
Bird flu is a recurring risk. It’s time food companies planned for it.
As egg prices remain volatile, businesses should think about embracing alternatives to the protein, writes Emma Ignaszewski of the Good Food Institute.

This seems bad. Over time, what people have assumed was the physical limit of human heat tolerance keeps going down. It used to be thought it was a wet-bulb of 35C, now it seems it's more like 32C for resting humans and 27C for people doing minimal physical activity.

A tricky thing about modern society is that no one has any idea when they don’t die.

Like, the number of lives saved by controlling air pollution in America is probably over 200,000 per year, but the number of people who think their life was saved by controlling air pollution is zero.

Climate economists: Does any economist think that economic model estimates of good enough that they should guide our policy response? e.g., "economic models predict GDP declines of a few percent in 2100 from 3C of warming, so we don't need to work hard to avoid this."

Songfestival-inzending Claude nu officieel gepresenteerd, ook videoclip bekend
Songfestival-inzending Claude nu officieel gepresenteerd, ook videoclip bekend
Songfestivalfans hebben Cest la vie van Claude al talloze keren kunnen beluisteren, maar nu is ook de videoclip gepresenteerd. Gisteren lekte de Songfestivalinzending uit, een dag voor de officile presentatie. Cest la vie, zei Claude daarover.ppIn Cest la vie zingt de 21jarige Claude in het Engels en Frans. Eind vorig jaar maakte hij in de talkshow Eva al bekend dat het nummer tweetalig zou zijn. Toen vertelde hij nog niet in welke twee talen hij ging zingen. Doorgaans doet hij het in het Frans en het Nederlands.ppAan tafel bij Jinek vertelde de zanger ook dat hij het nummer op 6 november schreef. Hij liet bij een concert in Paradiso al doorschemeren dat het over moeders in het algemeen gaat.ppHet Songfestivalnummer van Claude begint als een ballad om vervolgens in een dansbaar popnummer te veranderen. Het liedje blijft door het tientallen malen herhaalde lalala ook hangen bij mensen die geen Engels of Frans verstaan.ppDit is de officile videoclip van Cest la vie: ppClaude brak in 2022 door met Ladada Mon dernier mot. Vorig jaar werd hij door omroep AVROTROS gekozen uit ruim 300 inzendingen. In 2023 maakte de zanger een EngelsFranse versie van Ladada.ppDe Nederlandse zanger van Congolese afkomst staat op dinsdag 13 mei in Basel in de eerste halve finale van het Songfestival. De finale is op zaterdag 17 mei. Zwitserland mag het muziekevenement organiseren omdat Nemo vorig jaar met The Code het Songfestival won.ph2Geen aangifteh2pGisteren lekte het nummer van Claude aan het begin van de middag uit op sociale media. We onderzoeken natuurlijk of we kunnen achterhalen waar het lek vandaan komt, zei een woordvoerder van omroep AVROTROS. Maar het is lastig. We weten dat het eerder is gebeurd met andere landen.p

The blood that Elon Musk and his DOGE-cronies have on their hands because of the PEPFAR Funding Suspension.

200.000+ people not getting their daily HIV medication.

15.000+ deaths and counting.
February 25, 2025 at 7:25 PM
Meanwhile, the actual EA community is fuming about the PEPFAR cuts and has set up an emergency fund to continue coverage.

Elon is a just a loser who likes to act quirky. He found EA cool once because of the tech nerds but ultimately found out that nazism is a much better fit for him.
i think "an effective altruist is personally denying twenty million people their HIV medications despite a court order telling him to send the money" is a pretty good summary of effective altruism as a real world philosophy

Veel berichten over de opkomst van populistisch rechts gaan over manieren om kiezers op andere gedachten te brengen: alsof alleen zíj moeten veranderen.

In een halve eeuw groeide het aantal hoogopgeleiden in Nederland explosief. Daarnaast isoleren zij zich steeds meer: eigen sportclubs, eigen scholen, eigen media, eigen wijken. Deze ‘verzuiling’ blijf...

This is being rolled back, and doing so will cost many lives.
