The impact is already hitting science agencies hard. The NIH—the world's largest public biomedical research funder—has had to rely on leftover stopgap funds.

New grant awards have slowed to a trickle — exacerbating the effects of a record-long shutdown in October.

A timely and insightful perspective written by our former postdoc @justinkohare.bsky.social in @thetransmitter.bsky.social on dendritic integration and the urgent need to develop better ways to bridge molecular/cellular neuroscience with circuit/systems neuroscience 👇

DHS agents kidnapped Columbia neuroscience undergraduate student Ellie Aghayeva, lying to gain access to the building. trib.al/i0n38SC

This comes less than a year after DHS agents abducted Columbia University student Mohsen Mahdawi and graduate Mahmoud Khalil.

Federal funding for US biomedical research is moribund.

Since October 1 2025, NIH is -80% in new grants and -70% in values (total dollars).

Labs are closing down and researchers are leaving science.

To what end?

Columbia says DHS entered a dorm at dawn today under false pretenses, detaining a student in violation of the law and university policy.

No, ICE isn’t ‘retreating.’ It’s loading up to invade your town. | Will Bunch A much-hyped ICE pullback from Minneapolis is a blip in a looming nationwide surge of arrests, concentration camps.

MPLS was a great moral and practical victory for a new Trump-era resistance, but it was only the end of the beginning

15,000 new masked goons. 150 new ICE offices in every state, and a national network of warehouse concentration camps

It appears that this legend owns a little bookstore — and you can order books from him instead of Bezos. Link in next post.

This is excellent, careful, ruthlessly calm effective reporting from @bbcrosatkins.bsky.social in stark contrast to the earlier both-siding bollox from other BBC colleagues.

Do you appreciate @nws.noaa.gov's posts on Bluesky?

Did you know that this account is a pilot program that may or may not be continued and even expanded to NWS field offices?

They are targeting children because they are trying incite violence. I have talked to many journalists today, and they all made the same observation: Border Patrol and ICE have been rolling around with maximum aggression, lingering for ages as crowds, gather, seemingly trying to cause a riot.

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%.

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.

I flew down to south Texas today to do my job - investigate why people are dying in ICE detention centers.

I was just illegally denied entry to Dilley Detention Center. Because they have something to hide.

How Zohran Mamdani Beat Back New York’s Elite and Was Elected Mayor

This NYT story about how Mamdani dealt with the opposition by the city's elites fails to mention one particular elite institution: The NYT editorial page, which last June railed against him as "uniquely unsuited to the city’s challenges... lacks political savvy"

AOC: We have a future to fight for, and we're either going to do that together or you're going to be left behind. It's not about Progressive. It's not moderate, it's not liberal. This is about do you understand the assignment of fighting fascism right now? And the assignment is you come together…
