BREAKING: Texas lawmakers passed S.B. 37, which dramatically increases state control of public universities. Allowing politically appointed bureaucrats to police curricula and override faculty expertise is a direct threat to academic freedom in Texas.

📡Our antenna is getting into position. Our station engineers are pointing the antenna towards Voyager.

Proposed US retreat from the Solar System.

Looks like I may have to start learning the rules and residency requirements for European Research Council grants if I want to continue funded research in understanding how our planet and star formed in context.

The fact that the U.S. is turning inward and potentially set to decimate the science from its own space program while China is offering up its recently returned lunar samples for researchers around the world to analyze speaks volumes as to how the tides of science are going to shift.

The actual definition of "Habitable Zone"

It's a grift all the way down, isn't it?

🔭A 700 km diameter trans-Neptunian object pulled out of the @darkenergysurvey.org.web.brid.gy by heroic computational analysis, likely representative of a large, hidden class of objects.

This work by Chen, Ho, & Tung shows nicely one of those things obvious in retrospect: that the first stars formed in a supersonically turbulent medium produced by the collapse of their parent gas clouds (something that Ibáñez-Mejía, myself & Klessen showed for modern gas clouds in 2017). (1/2)

So much for freedom of speech and the press!

@niemandbesonders.bsky.social brings the receipts in this thread.

Data that tells many stories.

I don't know how much of this structure is interferometer noise vs real, but the idea that we can resolve any structure at all on the surface of a star other than the Sun is still astonishing.

They say it can’t be done, but here we are, California is generated 106% of California’s entire state electricity demand from renewables. California has a population bigger that 154 other countries around the world. It’s the 4th largest economy, in the world. Let that sink in. #energysky #greensky

🔭

Spectroscopic confirmation of a z = 14.44 galaxy. Our Aeos star-by-star simulations of galaxy formation actually run as far as that, maybe allowing a direct confrontation with observations? 🔭

Apparently falsifying a hypothesis is now forbidden by order of the Great Leader.

All of NIH funding to Northwestern University is frozen. This pause includes noncompeting approved funding, new and competing grants with fundable scores. No reimbursements for money already spent have been received since March. This situation is rarely reported so please Please get the word out!

"“How could it be that Mottones, a degenerate African, might advise a Carthaginian general!” (Livy 25.40.12) ... Carthage lost, while the multi-ethnic Roman army welcomed Mottones, and won.

Not water: it’s a mystery where streaks on the Martian surface come from, but a new paper rules out water as a cause and narrows down the other options 🔭🧪 www.universetoday.com/articles/pla...

The shift from Euro-American to Chinese research institutions shown in these rankings is dramatic 🧪

The journal @nature.com compiles a list of leading research institutions ranked by counts of "high-quality research outputs." (www.nature.com/nature-index...) Surely not definitive, but the change over the six years from 2018 to 2024 is astonishing. (1/5)

The NOAA science seminars continue tomorrow with a verrry relevant talk on "The Social Value of Forecasting Hurricanes" by Renato Molina. Unsurprisingly, he finds that public investments in hurricane forecasts pay for themselves many times over in reduced losses. Read: www.nber.org/papers/w32548

Why you don't let ChatGPT off a short leash...

Welcome! The Galactic Center has more gas, stronger magnetic fields, a bigger black hole, and more stars forming than anywhere else... follow @battersbot.bsky.social to learn lots more! 🧪🔭 [adding this to the science and astronomy feeds]

Climate scientist Jeff Masters explains how our new Energy Secretary Chris Wright is using numbers selectively plucked from IPCC reports to mislead Americans about climate change.

In response to NASA’s decision to force IFPTE-represented employees at NASA’s Goddard to move out of their offices in New York City, IFPTE altered Members of Congress that this action is not only disruptive, but wastes federal resources and harms the critical work of these scientists.

Built like a brick shithouse.

And thus shall we recognize traitors

Incredibly sad news that the only Mycetoma research center in the world was destroyed in Khartoum. Scientists lost 40+ years of samples, a significant setback in the fight against an already neglected disease. www.theguardian.com/global-devel...
