All of this is fucking senseless. Minnesota did not have an immigration problem. Trump sent his Nazi thugs here because he's racist against Somali people and to own libs like Tim Walz. Now two Minnesotans are dead and Minneapolis is on the verge of going up in flames. None. Of. This. Was. Necessary.

Last week, the Trump administration cancelled >$2B in mental health + addiction treatment funds. Only massive, rapid pushback caused them to reverse the decision.
But these programs remain at risk. So Grant Witness is now tracking SAMHSA grants. What found so far:

A PhD does not a universal expert make. Why must we hear from economists about dietary advice? Because they can do meta analyses?

The Trump administration's new dietary guidelines are "overall very sensible," Emily Oster writes in a guest essay. "This doesn't, however, mean that everything in here makes sense for everyone."

Happy new year! My all sky camera imaged the sky every 15 seconds and this picture shows what happened in the sky in 2025. It shows the length of the night and day with the hourglass shape, the monthly lunar cycle with the diagonal bands, the elevation of the Sun at local noon, and lots of clouds.

A paper published in Nature in September suggests a quarter of heatwave events from 2000-23 would have been near impossible without anthropogenic climate change. The paper also indicates that major carbon emitters are responsible for around 50% of the increase in intensity of these events. ⚒️ 🧪
Systematic attribution of heatwaves to the emissions of carbon majors - Nature
Climate change made 213 historical heatwaves reported over 2000–2023 more likely and more intense, to which each of the 180 carbon majors (fossil fuel and cement producers) substantially contributed.

This thread 1000x. And I have 0 patience for the "but there are so many problems to solve we need AI to help solve them all" argument. Since when has any *tool* developed by humans solved all of the problems we face?
I’m really concerned about early career scientists using generative AI in writing, because writing is how we think and reflect. There’s almost nothing *more* human than that, and to give that gift away to a machine is almost unconscionable to me

It appears that the U.S. Environmental Protection Agency (EPA) has, within the past week, scrubbed a large amount of climate change content from its official website, as well as *removed human-caused warming* from the discussion on its "causes of climate change" page.
