Full on concentration camps. "We don't know half of what's going on in the camps, but we know enough" is echoing from 85 years ago.

Stand With Minnesota Donation Directory Stand With Minnesota is a hub for supporting, learning, and taking action to support Minnesotans impacted by ICE and federal enforcement.

There’s so much need in Minnesota right now. Businesses are closing and rent is due soon.

If you want to help people here, there are links to rent relief & other vetted mutual aid funds on standwithminnesota.com. Please boost and donate what you can.

Thank you 🫶🏻

Attention folks in the weather, climate, disaster, wildfire, and Earth science communities: NSF has just published a new "Dear Colleague" letter inviting feedback (by Mar 13) on the proposal to dismantle the National Center for Atmospheric Research (NCAR). www.nsf.gov/funding/...

Thread.

After the shooting, an angry crowd gathered and screamed profanities at federal officers, calling them "cowards" and telling them to go home. One officer responded mockingly as he walked away, telling them: "Boo hoo." Agents elsewhere shoved a yelling protester into a car. Protesters dragged garbage dumpsters from alleyways to block the streets, and people who gathered chanted, "ICE out now," referring to Immigrations and Customs Enforcement. "They're killing my neighbors!" said Minneapolis resident Josh Koskie.

Alex Pretti was a colleague at the VA. We hired him to recruit for our trial. He became an ICU nurse- I lover working with him. He was a good kind person who lived to help and these fuckers executed him.

White. Hot. Rage.

“goobermensch” that is excellent

Remembering Gladys West: who used Einstein to create GPS Two main contributors enabled our modern global positioning system (GPS): Albert Einstein and Gladys West. Here's how she made it happen.

Remembering Gladys West: who used Einstein to create GPS

RIP to Gladys West: the "hidden figure" most people have never heard of, but whose work is second only to Einstein's in enabling and developing our modern GPS.

Anyway, once again, this could all stop if a small handful of Republicans in Congress grew a spine

For those outside the Twin Cities, the person posting this GoFundMe is a member of Minneapolis city council (and among the many locals doing absolutely heroic resistance to ICE), so it's legit.

Just saw on KARE 11 that this boy was sent to a detainment facility in Texas and that his family didn't know his whereabouts for almost 24 hours.

Sigh. Shutting down the National Center for Atmospheric Research will make the world a more dangerous place for all of us.

Ha, yeah, I have an identical memory - and after dark, since I was taking an evening class. Coldest walk of my life

Really not enjoying this particular period-doubling approach to chaos

And now I'm trying my hand at animating them by making the phase shift:

Save NCAR from being dismantled today! The Trump Administration has vowed to dissolve the center that provides critical extreme weather and climate data for our nation.

AGU has a Congressional email and call script up on NCAR:

🧵 NSF is reducing external review requirements and eliminating routine expert panels, citing staff shortages that this administration implemented. This change expands program officer authority. But the solution to flawed accountability isn't less public accountability.

I named my fists Schmidt and Cassegrain because you’ll be seeing stars

The Dark Energy Survey Supernova Program: A Reanalysis Of Cosmology Results And Evidence For Evolving Dark Energy With An Updated Type Ia Supernova Calibration We present improved cosmological constraints from a re-analysis of the Dark Energy Survey (DES) 5-year sample of Type Ia supernovae (DES-SN5YR). This re-analysis includes an improved photometric cross...

Two very interesting papers about dark energy on the arXiv today, both very relevant to the ongoing interest in possibly evolving DE as suggested by the DESI results 🔭🧪

Here's the first and potentially more explosive one: arxiv.org/abs/2511.07517

There were two hippos at the Urbana protest!

Yes, a decade of scale factor, exactly. Thanks for asking!

That’s just about right — the axion dominates in the period post-BBN and pre-recombination, but we find only up to a decade of modified expansion can be accomodated.

Such enhancements can jumpstart the formation of dark matter haloes, and thus potentially also star formation and/or black hole formation -- which is especially interesting since initial JWST results suggest there are things we don't understand yet about both stars and black holes in early galaxies

This altered expansion history changes the growth of matter overdensities on scales corresponding to dwarf galaxies and below - we can get either a modest bump-like enhancement, or a bigger plateau-like feature, depending on the underlying axion potential

Enhanced Matter Power Spectrum from Axion Kination after Big Bang Nucleosynthesis Despite stringent constraints from Big Bang Nucleosynthesis (BBN) and cosmic microwave background (CMB) observations, it is still possible for well-motivated particle physics models to substantially a...

New paper! with Raymond Co, Nico Fernandez, Akshay Ghalsasi, and Keisuke Harigaya, we look at well-motivated axion models that allow us to change the expansion history of the universe AFTER BBN

despite all the everything, going to try to use this to talk physics a bit, which is to say, today is a paper day
