HiPOD: It Shrinks! It Cracks! Here, we have a crater that lies close to Elysium, a major volcanic system on Mars. The whole region surrounding the crater was at some point covered by lava from the volcano creating vast lava plains. uahirise.org/hipod/ESP_04... NASA/JPL-Caltech/UArizona #Mars #NASA

On blackmail from the right, the basic asymmetry of US politics, and the various strategies of pundits and journalists to seek refuge, rather than truth (to quote Jay Rosen's seminal distinction), when confronted with this asymmetry. New column in The Guardian.

Remember folks, this👇🏼- sucking all the money out of public education to destroy it, while simultaneously making the wealthy wealthier & filling the coffers of religious schools, is a key element of Project 2025 — Vance’s blueprint for the future & the price Trump has agreed to pay for more power.

Arizona, the model for voucher programs across the country, has spent so much money paying private schoolers' tuition that it's now facing hundreds of millions in budget cuts to critical state programs and projects.

If you want access to free books, please get a library card. In the US, the more people there are with library cards, the more funding libraries have access to. Libraries provide more than books. They are a community resource. As an author and reader, I support libraries! #books #libraries

We need more, but credit where due: both The Nation (June 2024 issue) and Boston Review have run a breakdown of the Project 2025 “Mandate for Leadership” document. Media Matters, too. Lots of good work going on digesting this. www.bostonreview.net/articles/ins... www.mediamatters.org/project-2025

Where are the columnists who are experts in specific fields, breaking down what the Heritage Foundation + Trump want to do to each individual federal agency? E.g. I read the section dedicated to our intelligence agencies, and had to stop, since I was starting to feel a little nauseous.
