None of these attacked commentaries were even listed in the grant application itself as relevant, this is clearly just somebody grinding an axe and it is malpractice on his part as well as a huge judgment error by the Grant Office.

Washington Post article on STEM cuts at federal agencies. NSF tops it at -42%!

Washington Post article on STEM cuts at federal agencies. NSF tops it at -42%!

“Between January 2025 and February 2026, STEM and health employees at science-focused agencies saw nearly 15,000 jobs cut. The rate outpaced cuts among other federal workers.”

OPM data - Figure from Wash Post article 19 April. (Where US science has been hit hardest.)

NSF at -42%!

i'll take the bold (for bluesky) position that working for raytheon or northrup or whatever does not make you an irredeemable person, but palantir is very different because they are making karp's insane worldview the company's official public position, they're explicitly saying you believe this, too

A line graph of GISTEMP annual temperature anomalies, with a jagged bright red line growing from left to right across the page. The Y axis is labeled Temperature Anomaly in degrees Celsius, running from -.5 to 1. The X axis is labeled Year, running from 1880 to past 2000, with the plotted data extending to 2025. Although there is year to year variability, from around 1950 there is a clear upward trend. The highest values are for 2024, 2023, and 2025 respectively.

Climate change is the older & more commonly used term (vs. global warming).

Yet it has become a pervasive myth that scientists "used to call it" global warming but then changed to climate change, ostensibly because the planet stopped warming.

It is of course still warming.

I also agree with this that it almost certainly also requires a collaborationist legislature that eschews separation of powers to further partisan goals. (And as above to what extent you can disaggregate that from the Cold War would be tricky.)

a real inflection point. In some ways it's easier to look at post 9/11 GWOT as such an inflection point, but even that is probably only possible with the FedSoc-ing of the judiciary. And to what extent you can disaggregate FedSoc ascendance from Cold War is probably worth several PhDs worth of work.

No expertise here, but while there's a clear throughline from Cold War nuke Sole Authority / COG concerns to the W. Bush administration, arguments about the scope & individual vs. branch re Executive/POTUS obviously go back way way further & it's not clear to me that Cold War args or policies mark

A six panel grid from Action Comics #1. Superman stops a man from beating his wife with a belt. He throws the man against the wall; the man then tries to stab Superman. The knife breaks and the coward faints.

A six panel grid from Action Comics #1. Superman stops a man from beating his wife with a belt. He throws the man against the wall; the man then tries to stab Superman. The knife breaks and the coward faints.

Happy Superman Day.

Golden Age Superman was a New Deal hero and a champion of the poor and oppressed.

Never forget that Superman’s earliest enemies included: slumlords, crooked businessmen, corrupt politicians, mining tycoons, gangsters, and abusers.

In March, Matt Ridley gave the inaugural "Scientific Freedom Lecture" at NIH, on a lab leak origin of COVID-19.

The talk was so full of misrepresentations, omissions, falsehoods and lies that I will need several blog posts to debunk it. Here's Part I:

A close-up view from the Orion spacecraft during the Artemis II crew’s lunar flyby on April 6, 2026, captures a total solar eclipse, with only part of the Moon visible in the frame as it fully obscures the Sun. Although the full lunar disk extends beyond the image, the Sun’s faint corona remains visible as a soft halo of light around the Moon’s edge. From this deep-space vantage point, the Moon appeared large enough to sustain nearly 54 minutes of totality, far longer than total solar eclipses typically seen from Earth. This cropped perspective emphasizes the scale of the alignment and reveals subtle structure in the corona during the rare, extended eclipse observed by the crew. The bright silver glint on the left edge of the image is the planet Venus. The round, dark gray feature visible along the Moon’s horizon between the 9 and 10 o’clock positions is Mare Crisium, a feature visible from Earth. We see faint lunar features because light reflected off of Earth provides a source of illumination.

A close-up view taken by the Artemis II crew of Vavilov Crater on the rim of the older and larger Hertzsprung basin. The right portion of the image shows the transition from smooth material within an inner ring of mountains to more rugged terrain around the rim. Vavilov and other craters and their ejecta are accentuated by long shadows at the terminator, the boundary between lunar day and night. The image was captured with a handheld camera at a focal length of 400 mm, as the crew flew around the far side of the Moon.
