The data also reinforce a message that should be clear: American leadership in science and medical research requires far more than getting across the line on top-line budget negotiations and will require continued vigilance to track how HHS treats applications and existing awards.

NIH Data Book

The plot is only part of the story.

The data do not include lost science via terminations, freezes, stalled payments, and award delays. The collapse in awards rates will lead to job loss, gaps in research programs, and drive scientists to spend more time writing grants rather than doing science.

Graph of award probability of R35 and R01 from NIH factbook as a function of review rank percentile. As is apparent, 2025 is a significant departure, with lower award probabilities at all scores <40 and significant departures from norm, where even being in the top 10% is no longer a nearly certain indicator of success.

The data is in: the NIH goalposts have shifted.

What were once almost certain fundable scores have become coin flips and what used to be likely grants have become aspirational, leading to fewer awards.

Another manifestation of how HHS policies have led to fewer awards and less science.

An Army Corps project could wipe out one of Florida’s last thriving coral reefs The fate of one of the last thriving coral reefs in Florida may be imperiled by plans to widen the shipping channel leading into Port Everglades.

The US army corps of engineers is considering, right now, what would be the largest destruction of coral reefs in US history. To make a port slightly bigger.

People know this, right?

"It is not a mild infection, it is not a mild virus; it is a severe illness. And they kept on telling me they wish they'd known beforehand how bad measles was, so that they could have protected their family," [Dr. Nolen] said.

Degrading trust in vaccines comes with consequences.

This middle part of the thread points to specific examples of potential/ongoing automation of ideology-driven evaluation, i.e., using tools to screen for alignment with administration priorities. There are significant implications here for oversight of what is unfolding with NIH grants & reviews.

How Stand Up For Science is trying to 'pull every lever' to win over the public Stand Up For Science has become a formal organization and adopted a new strategy that's more confrontational with grassroots tactics

Real change takes a movement that goes into the public square, and as @cdelawalla.bsky.social explains, the public square has expanded & requires moving beyond business-as-usual engagement. More on @standupforscience.bsky.social and its strategic calculus:

Wait, but RFK Jr & Drs Bhattacharya, Makary, Oz, Prasad, & HΓΈeg kept saying that they would β€œrebuild trust.”

They won’t like this survey showing that:

β€œThe public is differentiating the trustworthiness of career scientists in the CDC, NIH, and FDA from that of the leaders of those agencies.”

Looking forward to @standupforscience.bsky.social's National Day of Action, taking place on the National Mall in DC and in dozens of cities/communities across the US.

Join in.

The more you speak up, the more space you create for evidence, accountability, and the rule of law.

Loyalty oaths and political litmus tests won't lead to new discoveries, innovations, or breakthroughs. NIH, NSF, and other mission-driven agencies need to get back to their mission, free of political interference. Oversight needed yesterday, the longer this is delayed, the more damage accumulates.

A governance and rights crisis will get worse... compounded by a public health crisis unfolding in detention camps with inevitable outbreaks of disease in unsanitary, crowded conditions operated by private companies.

Beyond just this tent camp, the system itself is untenable.

In reality, HHS issues fewer awards and research $-s to science & imposes more red tape/interference as HHS leadership try to align what should be evidence-based decision making by independent civil servants w/administration *political* priorities.

And, the NIH Director? Off managing the CDC.
