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!

In a new phase 3 trial, people randomly assigned to receive a flu shot made with modified mRNA were 34.5% less likely to be diagnosed with an influenza-like illness than people given a standard flu shot made with inactivated virus. We need to stop the anti-science attacks against mRNA vaccines!

Warming waters cause corals to “bleach” when these organisms expel symbiotic algae that provide nutrients, oxygen & vibrant colors. The latest global bleaching event - researchers estimate >84% of the planet's coral ecosystems have been affected since Jan 2023 - has made it clear the crisis is now.

Coral die-off marks Earth's first climate
'tipping point', scientists say

A surge in global temperatures has caused widespread bleaching and death of warm-water corals around the world.

'Our results indicate that a population of Treg cells acts to oppose excessive activation of sensory neurons through the production of enkephalins, endogenous opioid peptides that reduce nociceptive signaling, & by limiting its tone to restrain associated inflammation during inflammatory challenge'

Enkephalin-producing regulatory T cells in the skin restrain local inflammation through control of nociception

Regulatory T cells curb noxious sensory signaling to dampen cutaneous inflammation, a neuromodulatory mechanism for immunosuppression.

big one! a decade in the making. nadler & team develop tools to track lipid transport in living cells at single-species resolution. turns out non-vesicular, asymmetry-driven transport is the main architect of organelle identity. feels like the dawn of a golden era for lipid biology. rdcu.be/eBGJv

Quantitative imaging of lipid transport in mammalian cells

Nature - Directional, non-vesicular lipid transport is responsible for fast, species-selective lipid sorting into organelle membranes.

The lab's first paper is out now in @cp-matter.bsky.social We explored whether extracellular vesicles (EVs) could serve as structural elements in biomaterials—and whether doing so would confer intrinsic bioactivity. Artemis' thread explains how we used yogurt EVs to answer both these questions! 🧪

We are excited to share our new paper in Matter @cp-matter.bsky.social (www.cell.com/matter/fullt...: (1/19) We formulated injectable hydrogels in which extracellular vesicles (EVs) act as both structural and bioactive components 🧪. Thread below on the hydrogel design framework and bioactivity:

Are you from one of these states? Then we need your help to save American science! The Senate Appropriations Committee will be marking up the President's Budget Request for science on Wednesday. People have been saying the proposed cuts "decimated" US science, but that's wrong: they are apocalyptic

I'm honored to join the amazing community of Beckman researchers! I want to thank all the mentors and friends who helped me reach this milestone -- it's too many to list!! This funding will support our work integrating synthetic and natural nanomaterials to develop new cancer immunotherapies

"Women are PIs on 58% of the canceled grants, although they are PIs on only 34% of all active NSF grants. Similarly, Blacks are PIs on 17% of the terminated grants, although they make only 4% of the total pool. Hispanic PIs and those with disabilities were twice as likely to lose a grant."

Another scoop from Jeff Mervis (@policyhound.bsky.social): NSF's ~1400 grant terminations have disproportionately affected PIs from groups underrepresented in science: women, racial & ethnic minorities, & those with disabilities. 1/3 www.science.org/content/arti...

This is a project and an area I've been working in for years. We've published numerous papers on the topic, and recently went through a competitive renewal in which the science of the grant was rigorously evaluated and supported. And it was cut for cheap political points

Yesterday, the NIH R35 “Outstanding Investigator” grant to fund scientists in my lab studying antibiotic resistance was terminated for reasons not related to the content of the science, or any actions taken by me or members of my lab

One of the few powers we have as individual citizens, particularly between elections, is our consumer power. Effective boycotts could really make a difference, and I'd love to see guides for the top 5 companies to boycott. I for one cancelled Prime today and closed my Amazon credit card.

The Trump NIH is banning hires of new students and postdocs. This is devastating for NIH research and will result in a lost generation of researchers at the institution. Heard from a applicant today: "A lot of people are banking their entire careers on the [NIH student programs]..." #NIH 🧪 1/
