Another terrifying article about Stardust, with (what I think is) some new info:
- they claim they'll finally release info on their secret particles starting in early 2026
- they plan a first atmospheric test in 2027
- they've been funding academic research (with one PI named)

This is a VERY long piece about solar geoengineering that starts, scientifically speaking, badly, but gets better, but still has a few issues.
The Strange and Totally Real Plan to Blot Out the Sun and Reverse Global Warming
A 25-person startup is developing technology to block the sun and turn down the planet’s thermostat. The stakes are huge — and the company and its critics say regulations need to catch up.

The party that promised "free speech on campus" has made sure there can be no free speech on campuses.
This week, I withdrew from a speaking engagement at a public university because they sent me a list of prohibited “words & concepts.” I will not humor this censorship. It does a disservice to the stories I’m discussing & the audience, who deserve unfettered access to information & conversation.

A guy makes ONE tiny mistake (has a years-long friendship with the world's worst sex trafficker; brags about sexually harassing colleagues; is racist; says women are stupid) and his whole LIFE is blown up (does slightly fewer speaking engagements; keeps teaching at #1 university)??!?!?!?!?!
So Harvard is keeping this guy, but Claudine Gay had to step down over ginned up plagiarism accusations and bad-faith accusations of anti-Semitism.
Got it.
Got it.
Larry Summers tells @theharvardcrimson.bsky.social
he’s stepping back from all public commitments in light of his messages with Epstein, saying he is “deeply ashamed” and hopes “to rebuild trust and repair relationships.”
He will continue teaching.

So we've been working through tariff-exemption paperwork so we can purchase a Swiss-manufactured instrument. The tariff (and hence the instrument cost) just went down by $13K ... because the Swiss basically bribed Trump. Yay?
To negotiate a trade deal with the President of the United States, the Swiss government arrived with a "special Rolex desktop clock" and "a 1-kilogram personalized gold bar"

Rudy Bridges is younger than the Sitting President of the United States and 29 sitting United States Senators
It’s useful for people of my generation to be reminded that this wasn’t that long ago. Ruby Bridges isn’t just still alive—she’s only 71, not ancient!
65 years ago on Nov. 14, little Ruby Bridges was escorted into an all-white elementary school in New Orleans. Norman Rockwell, renowned for blissful depictions of Americana, did this remarkable painting for Look magazine. Printed as a double page, over-size spread, it's his masterpiece.

Yes, having grown up in the 1990s when this was the prime dark fantasy of the NRA, this is really something to behold. From a social science perspective, it's another piece of evidence that most of what we call ideology is really just identity politics.
It still blows my mind that the lawless government paramilitary stormtroopers from every 1990's conspiracy theory have arrived and all the don't tread on me 1776 people just pulled a fade.
