The White House's FY26 proposed budget includes severe reductions in support of NIH, NSF, NASA, CDC, EPA, NOAA and beyond.

These budgets represent cuts that would set back support to levels not seen in 25+ years.

How and why we share personalized information are grounded in parallel studies led by @asinclair.bsky.social (co-founder of #SCIMaP and future faculty at Rice):

The #SCIMaP project has included these terminations as part of our analysis flow, again linking the site of grant terminations to local economic impacts. The scope of grant terminations remain a surprise to many, both to those who oppose and to those who support them.

Amidst a government shutdown in which the White House has proposed slashing federal support of science by billions of dollars, our #SCIMaP team continues to assess the impact of research cuts on communities nationwide.

Precisely why it is time to speak up.

There's plenty of room for more to explain where this is going and why it is essential we change course.

"The newly appointed ACIP members appear to have limited or no experience as practitioners or policy makers for vaccine delivery; several are on record spreading vaccination falsehoods and are recognized antivaccination activists."

Amongst the worrisome bellwethers, there are substantive gaps opening in % of MAHA supporters who are *very* vs. *somewhat* confident in polio/MMR vaccines.

Turning this around is a national health priority.

The role of family pediatricians becomes every more important as @kff.org & @washingtonpost.com poll shows the power of connection and the danger of mistrust.

Without new HHS leadership, we should be concerned that some of the CDC structure & 'brand' will persist, but what the CDC does & says will be largely unrecognizable.

As one example, the MMWR landing page has no new issue but does have a political talking point banner.

I completed a PhD in Physics at MIT in '03. Even when the intensity seemed to be off-scale, there was one piece that I never doubted: the place had integrity, purpose, and passion.

It's clear the culture and drive of MIT remains.

MIT says no to the compact.

Meanwhile in Canada, there have been more reported measles cases in Alberta (cases: 1,923; population: ~5M) than reported in all of the US this year (cases: 1,563, population: ~340M).

Consequence: "The Americas region is at risk of losing its measles-free status..."

New post at Science Matters, reviewing "The War on Science" a collection of 30+ essays that views the war as having a single source - the left - while neglecting to reckon with longstanding (and accelerating) corporate and political threats from the right.
