Smithsonian removes Trump from impeachment exhibit in American history museum A temporary placard, on display since 2021, described the president's historic impeachments. Officials said the exhibit was restored to an earlier version following a review of legacy content.

Rewriting history: Smithsonian removes Trump, the only president impeached twice, from its exhibit about impeachment. "Only three presidents have seriously faced removal," the exhibit now says referring to Johnson, Nixon and Clinton @janaykingsberry.bsky.social www.washingtonpost.com/entertainmen...

On CNN, Vought repeats his lie: "They [NIH] in some respects caused the pandemic by their own research, for gain-of-function research."

Fact check: The viruses involved in NIH-funded research
"were genetically distant from SARS-CoV-2 and could not have been the source of the COVID-19 pandemic."

Fitch & Ruggles (2000), quoted in HSUS, put the median at 19.9 for white women in 1960.

I replicated the graph using a cohort life table (available here: www.ssa.gov/oact/NOTES/a...), for all races. Very close fit after age 50, still a big mismatch at younger ages, especially age 20 (1950 census). Looks like a major undercount of young men 1940-1970. 1/2

They are just a rearrangement of period life tables. Not hard to do, but you need a really long series of period tables, and they aren't complete until everyone is dead.

I made another one for women. still a significant undercount at ages 10 and 20, but not nearly as bad.

Two high-ranking officials at NOAA were placed on leave. While the reasoning behind the move is not clear, they led the investigation into whether NOAA’s scientific integrity policies were violated during the so-called "Sharpiegate" scandal of President Trump’s first term: cnn.it/452GqJZ

The upward bumps at ages 30 and 50 seem odd.

I see--you followed the birth cohort across censuses. I should read more carefully. That comparison would make sense if you used a cohort life table instead of period.

The period life table for 1930 does not reflect the past mortality experience of the 1930 population. Even more important, there is no reason to expect similarity between a life table and an age distribution--age distributions are more affected by fertility than by mortality.

I’d say that @stephencolbert.bsky.social is (with the lone exception of @maddow.msnbc.com) the most brilliant, humane person I’ve encountered in broadcasting. His mind works faster than anyone else’s at a level of sophistication that is unmatchable. Genuinely a generational talent.

Senate panel raises hopes that NSF will restore killed grants Republicans promise to work with Democrats to salvage defeated amendment

πŸ§ͺHave a terminated NSF grant? Or been impacted by such a termination? Call your Senators, esp if they're Repub!!

An amendment to restore killed NSF grants will later be debated on the *full Senate* floor, after it narrowly failed in committee today.

At a previous hearing in the cases, Young, a Reagan appointee, asked the defendants if the policy of the NIH was now β€œhomogeneity, inequity, and exclusion.”

BREAKING: A federal judge in Massachusetts (the Reagan-appointed William Young) has declared the Trump administration's cuts to NIH grants β€” ostensibly over Trump's EOs on gender ideology and DEI β€” are "illegal" and "void." He's ordering many grants restored.

I'm sorry. I stopped typing and just listened. I'll post summaries as they're published.

But the end was that Judge Young went on to defend judicial independence and to underscore the perilous moment in American history where racial discrimination is tolerated.

He ends with "Have we no shame?"
