This is really important. The US government wants to end independent scientific and medical research. Please comment and push back on the sweeping proposal that would give the White House veto and clawback power over Federal R&D funding. Here's guidance

I've seen a lot of info for specialized audiences (e.g. scientists, non-profits) on how to comment on the proposed OMB rule change for grants, but less for the general public. So I made this one-pager that can be shared more widely. docs.google.com/document/d/e...

"Accept (spotlight)" at ICML'26 😎 Our paper brings particle filters back to life: autoregressive diffusion models + posterior sampling yield optimal proposals for Bayesian filtering, scaling up to GenCast-sized systems. arxiv.org/abs/2605.20028 w/ Thomas Savary and @francois-rozet.bsky.social

Training-Free Bayesian Filtering with Generative Emulators

Bayesian filtering is a well-known problem that aims to estimate plausible states of a dynamical system from observations. Among existing approaches to solve this problem, particle filters are theoret...

Congrats again to authors of accepted #ICML2026 papers! The camera-ready deadline is 5/28. Drawing your attention to two specific features: 1. As last year, to help communicate research to a broad audience, papers will have lay summaries. Tips & details in blog 1/3

For those of you who love space exploration: we have robots exploring all across the solar system, and they can’t make anybody any money, they just discover cool stuff, so billionaires aren’t interested. Rovers and orbiters at Mars, orbiter at Jupiter, missions on the way to distant asteroids…

A sad thing about all this is that I have gotten kind of tuned out of space stuff because so much of it now is at least partly billionaire propaganda. To be honest, I didn’t even fully understand that this launch wasn’t until today. Just another thing I’d love to feel better about someday.

The long lines at airports now falls squarely on Speaker Johnson's shoulders. The Senate unanimously passed a bill to fund TSA, FEMA, and the Coast Guard. But Speaker Johnson is refusing to let the House vote on it. If you miss your flight, remember, this shutdown is on him.

On the value organizing using your own brain: 🧵 For my PhD, I read a mountain of books and over 2,000 European printed and manuscript maps & atlases c.1450-1650 (and some older ones). I identified 200-ish maps/atlases with distinctive imagery of peoples of the Americas (not just stick figures). 1/

The process of organization is one of the strongest metamemory strategies. Cut that out, and you've cut out learning. As a teacher and cognitive psychologist I find this all so sad and frustrating and kind of incomprehensible.

Spanish PM Pedro Sánchez: “Today more than ever, it is essential to remember that one can be against a hateful regime as is the case with the Iranian regime…and at the same time be against an unjustified, dangerous military intervention outside of international law.”

Too many “middle ground” AI arguments—“I have concerns, too, but we have to adapt”—proceed from what is to me a peculiar embrace of “inevitability” which seems to be magical thinking, a way of depoliticizing the political, of self-soothing in the face of an overwhelming challenge.

JFC I've heard that Fetterman is considering supporting the SAVE act. It's a disaster of a bill that would create sweeping disenfranchisement. Whoever your senators are, I don't care, call them. I don't wanna hear if you think they definitely will or won't support this, take 3 minutes & call.

"106,636 years of federal work experience were lost across the 10,109 employees with Ph.D.s who departed STEM or health roles 1 January–30 November." It isn't just the scientific knowledge but the *institutional* knowledge that's been lost. Rebuilding federal science will be a generational effort.

The US government lost more than 10,000 STEM PhDs last year, according to an analysis by Science of newly released OPM data, with 11 departures for every hire. And many OPM calls "voluntary" separations were probably pushed. www.science.org/content/arti...

Masked government agents are conducting “show me your papers” stops, detaining 5-year-olds to use them as bait, and brutally murdering U.S. citizens. Call it what it is — fascism. History will not look fondly on politicians and so-called "leaders" of this country who stood by and enabled this.

Let's be perfectly clear: every single Republican in Congress who allows this to continue without removing this president and prosecuting these lawless ICE murderers, is declaring their allegiance to a tyrant, and themselves enemies of the very Constitution they swore to defend.

Reminder: ICE’s budget has not been renewed — the House voted, but not the Senate — It will take 10 Democratic votes to stop it Pressure your senators
