Every single paragraph in this article is shocking. I had been quite pessimistic all along, but could not have imagined the speed and depth of the collapse.

ICE secretly kidnap autistic boy during bathroom break—never notify parents.

Mother reported him missing a week ago—turns out ICE had him detained the whole time.

He was helping sell fruit and asked to go to the restroom—by the time she was done helping a customer he was gone.

A classic case of irresponsible both-sidesism from the NYT. The story is that Trump and MAGA propagandists are lying about Portland to incite a conflict, not that there are different views of the matter.

An excellent response by MIT’s President Sally Kornbluf rejecting the Trump compact.

Other universities should do the same.

That's the key, yes:

Brain drain = missing brain gain

Won't make for splashy headlines, but let's just say I'm writing a lot of recommendation letters in A4 instead of Letter-sized format these days.

Thijs Heus @thijsheus.bsky.social · 1d

You won't notice those, is my guess. Those are the international postdocs/PhDs who now choose to go back to Europe/China/... instead of taking positions at the flaghsips.
Much of the US brain drain is going to be a lack of brain gain.

It's like Republicans arguing against CO₂ markets.

Sir, you're supposed to be the friend of the market-based solution.

"Europa erfindet die Energiewende, China baut sie"

aka

"Batterien statt der 30 bis 40(!) neuen Gaskraftwerke"

Mein Gastbeitrag mit @monika-schnitzer.com in der heutigen @zeit.de

www.zeit.de/2025/43/ener...

Energiepolitik in Deutschland:
Europa erfindet die Energiewende, China baut sie
Deutschland hat es versäumt, eine zukunftsfähige Energiepolitik konsequent zu verfolgen – und davon zu profitieren. Was es jetzt braucht, um wettbewerbsfähig zu bleiben.

Vor 16 Stunden
Ein Gastbeitrag von Monika Schnitzer und Gernot Wagner

In Brüssel lässt sich dafür eine wichtige Grundlage schaffen. Wenn wie bisher in jedem Mitgliedstaat der EU andere Vorschriften gelten, entsteht kein Wettbewerbsvorteil gegenüber den USA oder China. Ein gemeinsamer Binnenmarkt für Energie hingegen, abgestimmte Ausbauziele und eine gezielte Industrie- und Investitionspolitik, angetrieben von der lange anvisierten Kapitalmarktunion, könnten Europa wieder zu einem Standort machen, der nicht nur importiert, sondern auch produziert.

Am Ende entscheidet Energiepolitik über mehr als nur über die Strompreise. Sie ist Industrie-, Sicherheits- und Standortpolitik zugleich und damit der Schlüssel dafür, ob Europa seine Zukunft selbst gestaltet – oder sie von anderen geliefert bekommt.

David Simon, creator of ‘The Wire’, being interviewed by Ari Shapiro (NPR)

SHAPIRO: OK, so you've spent your career creating television without Al, and I could imagine today you thinking, boy, I wish I had had that tool to solve those thorny problems...
SIMON: What?
SHAPIRO: ...Or saying...
SIMON: You imagine that?
SHAPIRO: ...Boy, if that had existed, it would have screwed me over.
SIMON: I don't think Al can remotely challenge what writers do at a fundamentally creative level.
SHAPIRO: But if you're trying to transition from scene five to scene six, and you're stuck with that transition, you could imagine plugging that portion of the script into an Al and say, give me 10 ideas for how to transition this.
SIMON: I'd rather put a gun in my mouth.
