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.
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 government is saying that violence rules. That snatching foreign leaders and territories, and shooting US citizens in their cars at point blank range, is justified. That resistance is not only futile, it is dangerous. They can say these things. But they cannot force us to believe them.

Honestly, one of the worst parts of the scientific funding crisis is having to spend so much time writing papers, proposals, etc. in a state of fear. I don't do my best writing while afraid, let alone my best science!

I only rarely get to blend my art with my science, which is why I am happy that my illustration for our lab’s first paper is out today as the cover of Matter @cp-matter.bsky.social! We're so proud of this work, so in case you missed it, please check the paper out here: www.cell.com/matter/fullt...
On the cover: The cover image captures how a humble byproduct of the dairy industry becomes the foundation for a next-generation biomaterial in the work of Correa et al. Inspired by the saying “don’t cry over spilled milk,” the artwork depicts milk spilling from a carafe, with its droplets spontaneously capturing and linking polymer strands to form an intricate network in mid-air. This visual metaphor represents the study’s central theme: transforming yogurt whey-derived extracellular vesicles into dynamic crosslinkers that create injectable hydrogels with regenerative functionality.
