I'm very excited about this new paper, which kicks of our LEGO ERC project we started earlier this year towards general-purpose AI surrogates for simulating radiation-matter interaction. Instead of training AI surrogates for specific detectors or material distribution ...

Higher education has more public trust than any branch of the federal government. More than newspapers and TV news. More than banks or tech companies. We should remember this, and understand the motives of those who would like to pretend otherwise.

Pizza night, EDM show, followed the next day by homemade breakfast sandwiches and excellent coffee is a great start to the weekend after a long week.

Time to tap the sign that you can't have long lived PyPI tokens get stolen and have your project be a supply chain attack if you don't have any. Everyone please just use Trusted Publishers. docs.pypi.org/trusted-publ... lightning.ai/blog/pytorch...

Breaking: Trump has fired the membership of the National Science Board, which is oversees NSF. I have confirmed separately with multiple now-former members of NSB.

The move follows an administration push for cuts to the NSF and raises concerns in the scientific community that it could jeopardize a tradition of independent decisions about federal science grants. n.pr/4t2YxJI

Many American Catholics must have read a different version of the Gospel than the one I read growing up Catholic in Italy. Italian versions must have been woke

While I'm not physically at the DSI today for my friend @tylerjamesburch.com's visit and talks, it makes me happy to see that he got to meet my colleagues and know that I was welcoming him remotely. :)

My one-hour special “Rick Steves Iran: Yesterday and Today,” which helps humanize 90 million Iranian people, is streaming free and ad-free at www.ricksteves.com/watch-iran.

The President of the United States is threatening to commit war crimes and wipe out a "whole civilization" — all because he started a disastrous war of his own making and had no plan and no strategy for how to end it. This is abhorrent, and the American people do not support this.

Growing up in Illinois in the '90s during the Chicago Bulls dynasty means that this song acst as a signal for "lock in" mode for my brain. www.youtube.com/watch?v=OkC_...

Pete Hegseth needs to go, NOW.   Since the start of Trump's war in Iran, Hegseth has — without justification — continued firing some of our top military leaders.    Our service members deserve better than a power-tripping warmonger who thinks war is a big video game.  www.axios.com/2026/04/03/h...

In the context of the FY27 PBR it helps to go back to Robert Wilson’s famous testimony to Congress about funding for the NAL(Fermilab) in FY1970 and ask the natural question, why are there some people so hell-bent on tearing down so much of what makes this country worth defending?⚛️🧪

When it has been a long week reviewing some truly excellent proposals for @scipyconf.bsky.social is a great way to lift the academic spirit and make me excited for July 2026. :)

OK for fun: top funniest tweet ever? I am torn between "moon's haunted" and "Denise I was at your wedding."

BREAKING: In response to huge cuts in Trump's budget request, NSF is shuttering its SBE directorate. Staff will be transferred to other parts of the agency and "grants that align with Administration priorities" will be maintained. That & more w/ @maxkozlov.bsky.social & @edwrdchen.bsky.social

This is only true for people who understand neither science nor economics. The NIH budget for this year is FIFTY times larger than OpenAI’s $1B pledge. The foundation of US science & innovation is public funding. The private sector cannot replace it. US science is being killed

If the estimates were right, there were about 9 million people at No Kings rallies today. That would mean this protest was THIRTY TIMES AS LARGE AS THE TEA PARTY PROTEST which we were told, over and over again, was a massively important sign that US politics had shifted dramatically to the right

No more duplicate dependencies in pyproject.toml! Pixi Python packages can now set `ignore-pypi-mapping = false` to automatically convert `pyproject.toml` dependencies into conda package requirements. The goal is no configuration, this is a step in that direction!

Trump's newly announced council of scientific advisors is a startling departure from precious PCASTs: Instead of academic researchers or industry scientists, nine out of 13 members are billionaires, who have a combined wealth of over $900 billion. My reporting:

1/fb in 14h!

By chance I met Matthew Becker, of the conda-forge/core team, at the 2026 APS Global Summit as we both gave talks this morning. Always fun when physics and software make the world feel much smaller. :)

A Reuters photographer captured this image of a page from Pam Bondi's "burn book," which she used to counter any questions from Democratic lawmakers during an unhinged hearing today. It looks like the DOJ monitored members of Congress’s searches of the unredacted Epstein files. Just wow.

For reference, building 8-12 new beamlines at NSLS-II over the next 12 years or so is also about 500M$

Alberto Castañeda Mondragón was hospitalized with eight skull fractures and five life-threatening brain hemorrhages. Officers claimed he ran into a wall, but medical staff doubted that account. n.pr/4bHoZDU

GM: Charisma check. Mamdani: [rolls natural 20] GM: that’s a d6 how did you Mamdani: [direct to camera] Did you know you can check out board games at your local public library? 😊

Angus just gave a FOSDEM 2026 talk on Introducing Jupyter Book 2 and why this stack matters for reusable, reproducible computational publishing. 2i2c.org/blog/fosdem-...

Appalling news. @ukri.org has some serious questions to answer. How was prioritisation made and how is UK's world leading international science programmes being tensioned against national facilities?

The Factbook survived the Cold War and became a hit online. It mixed quirky cultural notes and trivia with maps, data, and photos taken by CIA officers. But it was discontinued this week. n.pr/3Mq3Y6i

We're excited to announce Pixi GUI, developed by our working student Felix Häcker! With the goal to make Pixi accessible to a wider audience while also empowering expert users. Find out more in Felix's blog post: prefix.dev/blog/introd...

The @uwssec.bsky.social team wrote up why they switched to Pixi for all their research software engineering: "Pixi has allowed us to remove the friction of package management to focus on what matters: writing better, reproducible scientific software." prefix.dev/blog/seeking...

1. It was not an accident. 2. It was not a staffer. 3. While the president may have dementia his racism is not due to dementia. 4. He isn’t sorry. He means every racist thought he shares. 5. His base agrees with him. 6. He will do it again. 7. No one in power will hold him accountable.

No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition. Which just makes me want to share it again: www.nature.com/articles/d41...

Just like with Kilmer Abrego Garcia, the biggest sin any targeted immigrant can commit is winning battles — legal or PR battles — against the government, and they just won’t let those losses go

“It seems our university leaders cannot even say that it is wrong to murder a former student in broad daylight because some people might disagree,” geography professor Kate Derickson

I will be giving the Nick and Maggie DeWolf public lecture at the Aspen Center for Physics tomorrow. See, it’s in the newspaper. @aspenphysics.bsky.social

Scaling Laws in Particle Physics Data! This is a result I've been itching to share and it's finally out. One of the big open questions is how much better AI-based methods at particle colliders can still become. 1/4

How many STEM Ph.D.s were lost from the U.S. federal government last year? My colleagues @mghersher.bsky.social and @policyhound.bsky.social dug into a recent data release to find the answer. A @science.org exclusive. www.science.org/content/arti...

There have been 3 homicides in Minneapolis this year. Trump’s agents committed two of them: a mom and a nurse who cared for our Veterans. Stay the hell out of our cities.

This moment in history provides us with incontrovertible evidence that all the conservatives who claim to be extremely devoted to freedom of speech and the right to bear arms, and opposed to the encroachment of tyranny, are completely and totally full of shit. It's all white supremacy and greed.
