I fear sensible dems like @petebuttigieg.bsky.social will spend forever in the political wilderness because DSA and affiliated candidates will keep losing elections by moving the Overton window away from the mainstream with boutique nonsense, and continually hand the right wing easy wins.

Every sentence not just wrong but spectacularly wrong. When it comes to crime, two groups with more Dunning-Kruger confidence that knowledge? doctors and lawyers.

With fewer reviewers and AI helping generate more academic articles, anticipate more desk rejects. Not because articles aren't technically proficient, but because editors will have to be more selective. I foresee editors will have much greater influence in the future.

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again. www.nature.com/immersive/d4...

This line graph illustrates the percentage change in agency staff levels from the previous year for nine major U.S. federal scientific and health organizations between the fiscal years 2016 and 2025. The agencies tracked include the CDC, Department of Energy, EPA, FDA, NASA, NIH, NIST, NOAA, and NSF. For the majority of the timeline between 2016 and 2023, the agencies show relatively stable fluctuations, generally staying within a range of +5% to -5% change per year. However, there is a dramatic and uniform plummet starting in the 2024–25 period. Every agency depicted shows a sharp downward trajectory, with staffing losses ranging from approximately -15% to over -25%. The Environmental Protection Agency (EPA) shows the most significant decline, dropping to roughly -26%, while the National Institute of Standards and Technology (NIST) shows the least severe but still substantial drop at approximately -15%.

To contextualize this week’s political commentary, of the 2,647 identified extremist violent offenders in the US since 2000, far-right extremists were more than 7 times more represented in the data than far-left extremists. * No, this isn’t to negate the abhorrent shooting this week.
