New from #SCIMaP - analysis of the White House’s Proposed FY 2026 National Science Foundation Budget.

Take-home: Slashing NSF by >50% will lead to ~$11 billion in economic loss and extensive job loss and reduced training opportunities in communities nationwide.

Put all of this into a time capsule... a harbinger of where the White House and HHS sees the (business) opportunity space in health care, research, and medicine.
There's an exclusive, closed-to-media MAHA summit tomorrow. Here's the full agenda I was leaked

In attendance will be JD Vance, RFK Jr, Bhattacharya, Makary, actor Russell Brand (who is facing rape and sexual assault charges), and dozens of other MAHA influencers and people in Trump's orbit

This looks amazing!

I also wrote about the health "plan" here. The ACA brought sweeping protection to tens of millions of patients, enabling them to secure coverage. Trump wants to do away with all of that, replacing insurance protection with direct payments in a much costlier system. www.msnbc.com/opinion/msnb...

I spoke to CNN about how demoralizing it was to watch Stanford leadership stay silent while contrarians on campus launched unscientific attacks to stifle Stanford researchers. Now, those attacks have gone nationwide and much of MAHA leadership have ties to Stanford.

Canada has just lost measles elimination status. The U.S. will undoubtedly follow shortly.

Elimination means that there is no continuous spreading of measles within the country for a year or longer.

Canada and the U.S. have blown it, and it’s largely the fault of the anti-vaccination movement.
Canada loses measles elimination status after three decades, health agency says
Canada has lost its measles elimination status after nearly three decades due to its failure to curb a year-long outbreak, the country's public health agency said on Monday.

If you are listening to MAHA when thinking about public health "reform" then really listen to what they want:

"I’ve come to this anti-vax conference with a message that we need to be more boldly anti-vax,” said Mark Gorton, the president of the MAHA Institute.

Does Sen. Cassidy, a strong proponent of #vaccines, regret voting to confirm RFK Jr. as health secretary? “I just have to quote Kierkegaard — You live life forward,” is his reply.
That's not a "No."

This is particularly enraging because 1) @standupforscience.bsky.social is doing a LOT against RFK Jr/MAHA and we are just getting started and 2) because I HAVE SPOKEN WITH HIS WRITERS AND PRODUCER.

A Sharon Begley byline, almost 5 years after her death.

Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."

Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.

"[P]rocedurally, had she denied the request, the Justice Department could have gone to another justice.

Finally, and perhaps most importantly, by issuing the order herself, she was able to set the limits."

BREAKING: DOJ goes to SCOTUS trying to stop a district court order that USDA pay out full SNAP benefits this month.

The First Circuit denied an administrative stay, but has not yet ruled on the stay request. And, CNN reported that USDA is already processing payments.

DOJ went to SCOTUS anyway.
#BREAKING: The Trump administration is asking #SCOTUS for an immediate “administrative” stay of a Rhode Island district judge’s order that is otherwise requiring it to resume the distribution of SNAP benefits from other funding sources no later than the end of today.

See below for less subtlety.

More folks will have to ask groups like @scholars.org that uncritically amplify the arguments of In Covid's Wake precisely what they are doing. Is it that they didn't read what the authors wrote, actually agree, or are just 'getting along'?

"COVID Revisionism Has Gone Too Far"

Ya think?

www.theatlantic.com/ideas/archiv...

Fascinating given that "In Covid's Wake" is unable to grapple with (i) the extent of COVID mortality and morbidity; (ii) lives saved due to interventions; (iii) missed opportunities to align health + the economy.
COVID Revisionism Has Gone Too Far
If the center and left succumb to the view that “nothing worked,” no one will remain to defend sensible public-health measures the next time a pandemic comes around.

It's definitely a choice @scholars.org

Director Bhattacharya decided to weigh in on X/Twitter about the impact of the government shutdown.

He (not surprisingly) focuses on the impact of the MAHA agenda. Of course, delays of research for months (which could be minimized by NIH with planning) will have little effect on MAHA actions
