“Students should understand AI’s numerous social, economic, health, and environmental costs. Giving lip service to these big ethical issues while hastily integrating AI sends kids a strong message — the adults don’t really care and neither should you.”

On Thursday, the Trump administration asked the Supreme Court to grant them a stay on the Massachusetts vs Kennedy/ APHA vs NIH ruling. This decision will occur on the shadow docket, with no formal hearing.

When you call to thank them, also tell them to continue taking a stand by ensuring science funding isn’t further cut - demand a CLEAN CR w/ protections against rescission in September, and to SHUT IT DOWN, if necessary

Trump is attacking NIH because politicizing funding can force universities to become conservative thinktanks It's bad, folks. The real war is on free thought in the United States.

On Columbia:

We in the #NIH resistance published a piece in March. “Trump is attacking NIH because politicizing funding can force universities to become conservative.” Yes.

There is a straight line between attacks on science and universities.

If we do not allow for redemption then with it goes the possibility of atonement and moral progress. Also, I would say the legacy of the Rwanda genocide shows that redemption is very much a possibility.

"These eugenicist modes of thought persist and recur, even into visions of the future like those of transhumanism, where thinkers can envision changing the human body into that of an angel but still fail to imagine a bathroom stall wide enough for the wings."

Decades of mechanistic talk about university degrees as if they were bundles of 'skills' and 'prep' are about to be proved completely wrong (obviously). Want to get a real boost? Do History or English.

Exclusive: NIH to dismiss dozens of grant reviewers to align with Trump priorities The move would undo years of work, leaving advisory councils understaffed, and without the full expertise needed for reviews.

NEW: In an unprecedented move, the NIH will soon disinvite dozens of scientists about to take positions on advisory councils that make final decisions on grant funding.

NIH staff were told to select others aligned with the Trump administration and told to expect placements by political appointees.

Are a few people ruining the internet for the rest of us? Why does the online world seem so toxic compared with normal life? Our research shows that a small number of divisive accounts could be responsible – and offers a way out

Only a small % of people engage in toxic activity online, but they’re responsible for a disproportionate share of hostile or misleading content on nearly every platform

Because super-users are so active, they dominate our collective impression of the internet www.theguardian.com/books/2025/j...

I think this illustrates how neuro has similar/same theory build challenges as the rest of cog sci. Lots of great work on the "theory crisis" in the last 5+ years that's directly relevant.

I think that interpretation is common, but he says pretty explicitly in the final chapter that he's *not* offering a recipe for doing science, even if his discussion might seem that way.

I don’t think anyone is prepared for what they just did w/ ICE.

This is not a simple budget increase. It is an explosion - making ICE bigger than the FBI, US Bureau of Prisons, DEA,& others combined.

It is setting up to make what’s happening now look like child’s play. And people are disappearing.

At a recent hearing, Sen. Hassan asked Bhattacharya whether he'd follow the president's directives even if it meant breaking the law.

Bhattacharya said, “I don't believe the president will ever ask me to break the law."

Here, NIH is defying a court order — which ruled the agency broke the law

Go Ahead, Make the Case that Science, Free Speech, and the NIH are Thriving Under Dr. Jay Bhattacharya Many smart people reassured us that Dr. Jay Bhattacharya was both qualified to run the NIH and motivated to make it a better place. They should make the case they were right.

Declarations that Jay Bhattacharya would be a great NIH director were similar to declarations of herd immunity 4 years ago.

The same people did all they could to numb us to grave threats.

Don’t worry- they said.

And now they won’t defend their own words.

E.P.A. Workers Warn Trump Is Politicizing Their Work

“More than 270 employees of the Environmental Protection Agency signed a letter on Mon denouncing the Trump administration’s efforts to politicize, dismantle and sideline the main federal agency tasked with protecting the environment and public health.”
