As far as I can tell, this $8B in cuts to clean energy as part of the government shutdown is on top of the $13B from the pocket rescission.

"...this administration is not serious about American energy dominance”.

Big surprise.

ICE is going to apartment buildings without a warrant, breaking down the door of literally every unit, zip tying & detaining everyone inside, & arresting people for things that have nothing to do with immigration.

This is a 5 alarm fire. This is what a secret police force does.

“ABC7 spoke to Pertissue Fisher, a woman who lives in the building. She said ICE agents took everyone in the building, including her, and asked questions later….’They was bringing the kids down, too, had them zip tied to each other.’”

It can’t happen here, you say. But it is happening.

🧪 Excellent summary of the important work being done by @joshuasweitz.bsky.social and Alyssa Sinclair, mapping impact of NIH budget cuts.

Great that new funding will extend their work to other agencies.

Vital to let your lawmakers know of economic impact in their districts of proposed cuts!

Our latest results on the laminar-turbulent transition in pipes. Body forces acting in the fluid give a tricritical point once the body force is strong enough. Centrifugal force in a curved or helical pipe is an example. Bjorn Hof's experiments see these effects.

During the day yesterday in California, >75%of all electricity was produced by renewable #energy, including solar.
After the sun went down, half of all electricity STILL came from renewables, including wind batteries, hydro, geothermal, etc.
The graph from the California independent system operator showing the mix of electricity produced yesterday generated from imports, exports, wind, nuclear, fossil fuels and lots of solar and batteries. Tweet from the Department of Energy saying wind and solar energy is essentially worthless when it's dark outside and the wind is not blowing. Basically showing the DOE doesn't understand energy.

The President of the United States is threatening to go to war with an American city.

This is not a joke. This is not normal.

Donald Trump isn't a strongman, he's a scared man. Illinois won’t be intimidated by a wannabe dictator.
