NEW — I wrote about my visit to Delaney Hall, the ICE facility in Newark, NJ where detainees are on a hunger and labor strike in protest of rotten food, unpaid work, and unjust detainment, and where protesters outside have spent the last week drawing ICE's ire while keeping strikers' demands alive.

It is refreshing, delightful, wonderful, revelatory that the Pope is using his position to promote general ethical norms in useful context, as opposed to narrow interpretation of arbitrary canonical rules. Now, should I go and read the entire new Encyclical?

How to plan a future in turbulent times - when the frameworks that worked to get us where we are now most likely won't succeed to get us where need to go next.

It's hard to understate how nearly complete California's grid's transition away from fossil fuels is. Grid-scale battery deployments mean, last night, batteries were the #1 source of power for the state's grid for 3 hours.

In @nytopinion.nytimes.com “The key to Trump’s power isn’t just that he accurately sensed that much of the Republican establishment paid lip service to principle but really cared about power,” David French writes. “It’s that he knew millions upon millions of voters possessed similar values.”

My favorite paper of 2019 has just been conditionally accepted at AER (lmao) The Voting Rights Act rapidly increased Black wages in the South via public employment & redistribution static1.squarespace.com/static/59dc0...

As @mzjacobson.bsky.social shows, California isn't just talking about the transition, it's far into it. Methane-burning is now but a minor part of the energy of the world's #4 economy.

A real banger from @jamellebouie.net www.nytimes.com/2026/04/29/o...

This is correct. There is no future of democratic self government in the US with an unreformed Supreme Court. The Court is riddled with corruption and abuses of power and rooting out that corruption is a sine qua non of civic democracy in the United States.

A strong, quantitative argument for reprioritizing cancer research funding.

Hungary tried national conservatism. The result: a lagging economy, rampant corruption, and a declining birth rate. Voters just delivered the verdict. Cato’s Johan Norberg explains what it means—and why it matters far beyond Hungary.

Cato gets this one wrong. The rich FACE the highest tax rates but don't actually pay them. The Buy/Borrow/Die strategy means marginal actual tax rates for the wealthy are actually zero. www.theatlantic.com/economy/arch...

Send JD Vance to campaign everywhere you want Dems to win.

Viktor Orban has conceded the election in Hungary!!! A reminder that authoritarianism can be defeated, even when the playing field is tilted -- because voters resent corruption and misrule. But much depends on having the right candidate to oppose the authoritarian. www.nytimes.com/2026/04/12/w...

I'll be at the MIT Sloan Climate / Sustainability summit next week. Say hi!

So Iran (the actual country) mocked Donald Trump's horrible 'deal" by posting MY video all over social media. And I have to say, I'm kinda flattered 😉 Here's the full version. (They cut off the ending and cropped out my watermark) #DonaldTrump #Iran

Wise words from Spain's Prime Minister: “The momentary relief cannot make us forget the chaos, the destruction, and the lives lost. The govt of Spain will not applaud those who set the world on fire just because they show up with a bucket. What is needed now: diplomacy, international law and PEACE.”

On the 58th anniversary of Dr. King's assassination, it's time to reckon with the media's troubling role in the civil rights struggle. (I pitched this to @nytimes.com who found it "fascinating..[but] the news is making deeper & certainly more historical pieces very hard." But they're the news.) A 🧵

This week I will again listen to a piece of music so key to my appreciation of the human condition that I keep it to just once per year, to keep it as fresh as it is moving and monumental. I refer, of course, to Bach's St. Matthew Passion. Dear Blueskyers: what version this year? #musicsky

Went to the Sausalito #NoKings protest with brilliant constitutionial analyst / lawyer @cathygellis.bsky.social Good crowd. One nutball crank shouting the "republic not a democracy / you lose" nonsense. Good humor and persistence and nice creative signs and two short speeches.

Let us consider the Emperor Commodus, who attired himself as Hercules, claimed to be a god, attempted to rename Rome after himself and raped every girl and boy whose crossed his way. His reign was described by Gibbon as marking the onset of the moral and spiritual collapse of the Roman Empire.

No Kings protests are set across the Bay Area Saturday, including a major march in San Francisco. Here’s what to know about routes, street closures, transit changes and expected turnout.

Today, we're launching Bundle Passes. It's a new way for journalists to team up and give new audiences 30, 60, or 90 days of access to their paywalled content in a bundle.

Folks, we went to the Oracle of Delphi, a very beautiful woman. And she said, they told me not to say it, should I say it? She said that if we went to Persia a great empire would fall! So we’re feeling pretty good about how it’s going.

Emmy Noether was born #OTD in 1882. She made groundbreaking advances in abstract algebra, but is probably best known for her eponymous theorems articulating the deep connection between symmetries and conserved quantities in physics. 🧪 ⚛️ 👩‍🔬 Image: Public domain, photographer unknown

This note on the low cost of Chinese nuclear is really important. Comparing to Lazard's estimates of the levelized costs of energy (the industry standard): Chinese nuclear at 2–3 $/W capital cost maps roughly to an LCOE of about 40–60 $/MWh under typical nuclear assumptions. / a tiny thread

THREAD: Cherise Doyley was in her 12th hour of contractions at the hospital when a tablet was brought to her bedside. On the screen was a Zoom call with a judge and several lawyers and doctors. She was in court, a nurse told her. The reason? For failing to agree to a C-section.

Something terrifying. AI fabs are eating farmland. Farmers are aging out. It costs more to farm than ever but crop prices remain low.
