My favorite artifact in the "you don't need AI to do art" discourse is, of course, screenwriter Dan O'Bannon's sketch of the facehugger to explain it to Giger.

While reporting this, I had something happen that's never happened. A comms rep for one of the co's disputed my reporting and said what I was telling them was untrue because it was not in Grok, xAI's chatbot.

I was looking directly at the files. And this person was using AI to challenge the truth.

From 1981 to 2016, hermit thrushes migrating through Chicago became smaller, with shorter bills and longer wings, relative to body size— there are genetic changes associated with shortening bills, but not the other changes 🌿 🪶

The Texas AI Boom is Outpacing Water Regulations Each data center can “drink” as much as an entire community. Yet, Texas does not require these tech firms to disclose projected or actual water consumption.

"We have no way of reconciling what these cases will do to water supplies."

New from Miranda Williamson: The world’s largest artificial intelligence data center complex is being built in Amarillo, and it’s almost seven times the size of Central Park.

Illinois Rewilding Law, first in US, a step toward state wetland protection Officials and environmentalists, pushing for state regulation of wetlands, say law will help close federal gaps after Trump rollbacks.

As sweeping changes to the federal Clean Water Act in recent years have weakened protections for wetlands, Illinois has become the first state in the nation to officially recognize a conservation tactic known as rewilding.

Alex Pretti from his early days working at the VA

Alex from our time working together, while he was in nursing school. Later, he moved to ICU, working as a nurse to support critically ill Veterans. He had such a great attitude. We’d chat between patients about trying to get in a mountain bike ride together. Will never happen now

the regime considers all resistance violent resistance. you chanting while holding a sign and carefully remaining on the sidewalk is as worthy of the death penalty to them as someone throwing a Molotov.

Experts who have followed authoritarian regimes abroad can tell you a lot about day-after reprisals to mass movements, which look a hell of a lot like today's killing

Very cool that Congress just renewed ICE's budget with absolutely zero concessions

You may’ve seen coverage of a new report on the threat to national security from environmental collapse.

A common response that’s got my goat is: “Look, it’s not just tree-hugging enviros saying this, it’s hard-nosed spooks!”

"There is one political problem from which all others follow, [including] the devastation of the living world.

It is simply stated: the extreme wealth of a small number of people."

If you truly care about nature, it's madness to ignore the root cause of its destruction.

It's horrific but also this is pretty much a regular arrest. That's how violent arrests are. I am glad people can see it and be horrified -- that's what police are out there doing every day, legally. Every 3 seconds basically.

One of the biggest tells of gen-AI ants is the waist.

I think this is because most ants belong to one of two subfamilies- Myrmicinae and Formicinae- that have very different waist structures, but the algorithms often average them into fake ants in a non-existent morphospace in between.
