"As the nation's premier science organization, and one that performs lots of analyses for the government, the National Academies would seem to be in a position to have its concerns taken seriously by members of Congress. And, given that the present and future of science in the US is being set by policy choices, a meeting entitled the State of the Science would seem like the obvious place to address those concerns. If so, it was not obvious to Marcia McNutt, the president of the NAS, who gave the presentation."

aaaand it finally happened. Totally sucks... and yet it doesn't even crack my top-100 list of things going on in the US to be upset about.
Termination notice from the US EPA, stating in part "This EPA Assistance Agreement is terminated in its entirety effective immediately on the grounds that the award no longer effectuates the program goals or agency priorities. The objectives of the award are no longer consistent with EPA funding priorities."

"It may seem prudent now to keep our heads down and hope this storm passes. History tells us this is unlikely. Free inquiry and the public exchange of our findings pose a real threat to authoritarian government. If we continue to preemptively change our language, pretend that the deep inequities of class and race and global power that shape our world are not relevant to the governance of our institution, or demonstrate to both Trump’s agents and the public that we will fold under the slightest pressure, we will find ourselves, perhaps not so long from now, without any dignity left to protect."

Love getting these emails from the Hawaiian Volcano Observatory, because they mean (1) there's an amazing lava fountain to watch online (www.youtube.com/usgs/live), and (2) the USGS employees who write these important updates haven't yet been fired by Trump/Musk.
Text of email: HAWAIIAN VOLCANO OBSERVATORY STATUS REPORT U.S. Geological Survey Tuesday, March 11, 2025, 3:35 AM HST (Tuesday, March 11, 2025, 13:35 UTC) KILAUEA (VNUM #332010) 19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m) Current Volcano Alert Level: WATCH Current Aviation Color Code: ORANGE Activity Summary: Episode 13 of the ongoing Halemaʻumaʻu eruption began at 2:36 a.m. HST on March 10. Fountains reached heights of 400-500 feet (120-150 m) by 3:30 a.m. Episode 13 was preceded by small, sporadic spatter fountains 15-30 feet high (5-10 m) that began at approximately 1:30 p.m. HST on March 10 within the north vent and continued to increase in intensity until 6:35 p.m. HST when spattering could be seen on the streaming webcam (V1). Spattering continued to increase during the night and into the early morning hours of March 11. Lava erupted from the north vent at 2:36 a.m. HST and high fountains began about 10 minutes later. Fountains from the north vent are now 400-500 feet (120-150 meters) by 3:30 a.m. HST. Lava flows from the north vent have covered 20-30% of Halemaʻumaʻu crater floor.

Trump has said many, many stupid and dangerous things over the years, but this one may be the stupidest and dangerous-est yet
NYT quote: "The exchange ended with Mr. Trump telling Mr. Duffy that he had to hire people from M.I.T. as air traffic controllers."

Don't worry, Google AI has a helpful explainer
The IUPAC name for oxidanium is oxidanium, and its chemical formula is H3O+. It is also known as the oxonium ion, hydronium ion, and aquahydrogen(1+).

Yes, it died doing what it loved (spinning really really fast). We had a screen - took a beating but mostly held. Haven’t found any shards…

This paper is great for a whole bunch of reasons, but my favorite part is definitely Figure 1, the single best smog-chamber photo ever published
