Of all the harm this administration has done to US science, today's proposed changes to the way federal grants are awarded and administered is the most damaging yet. The text of the federal register document is impenetrably tedious by design, so here's an excellent summary of what it says.

Especially if you're on the fence about it, protest today. Fascism is isolating and lonely. Its very goal is to make you feel like you're the only person unwilling to accept a cult of personality. On days like today you fully realize there are more of us than there are them. You will feel better.

"Sources said the administration is specifically considering a full termination of federal grant funding for the University of California and California State University systems." Pure vandalism. This could never happen in a country with functioning checks and balances.

NIH's work saves lives—& Trump is gutting it. Straight from D.C. I headed to Seattle Children's to hear from researchers & patients alike about the importance of NIH funding—it's not just about lines in a budget, it's about lifesaving discoveries. We ALL need to speak up to save it.

Replying to @ddiamond.bsky.social

See this chart for one stark example: NIH funding has dramatically slowed down. Grant awards are down *$3 billion* so far, compared to same time period last year I asked the White House to explain. “This is not a researcher entitlement program,” said an official, defending their new approach.

I want to highlight: ...trainees are the lifeblood of biomedical research and its future. Supporting young people committed to public service through research and health care is an investment in medical advancements and public health... We see you. You belong here.

We lose: ✖️Basic science advancements that help us understand the causes of disease. ✖️New treatments and cures for diseases like cancer and Alzheimer's. Our ability to combat infectious diseases. ✖️the biomedical workforce. ✖️the next generation of researchers and health professionals.

Let's not forget that apart from science advocacy the Rauch lab also does kick-ass science! Together with the @psmitchej.bsky.social and Tait Wojno labs, we show that #tuftcells can induce specific protective signaling after recognition of intracellular bacterial infection via the #inflammasome!

First authors Madeline Churchill and Ankit Pandeya @nkeet50.bsky.social from @rauchlab.bsky.social show that tuft cells, known for their role in anti-parasite defenses, can also contribute to anti-bacterial responses in the small intestine. rupress.org/jem/article/... #InfectiousDisease

🧪 The attack on science could have a generational effect. We risk losing a wave of early-career researchers to these cuts. And biomedical science in the US will be less ambitious, less competitive & lead to fewer breakthroughs. So much is at stake. My latest for @opinion.bloomberg.com (🎁 link):

bloomberg.comNIH Cuts Create a Lost Generation of ScientistsTrump administration attacks on the National Institutes of Health mean biomedical research will become less ambitious, less competitive and result in fewer breakthroughs.

1/4 Today, I honor Dr. Lee Herzenberg, a renaissance woman and a pioneer. #InternationalWomensDay #WomenInScience #IWD I’ve been fortunate to be mentored by women at home and in science. I met Lee in 2004, and her mentorship profoundly influenced my career and values.

The study section I sit on (Innate Immunity B) will be rescheduled to April. Just putting this out there since folks have been getting no notifications about whats going on with their grants.

It may not be cool or hip in some circles, but we legitimately do need a massive amount of people to run for office. Flood the school boards, councils, county seats, state legislatures, Congress, etc. Big changes at the top happen when the ground shifts at the bottom. And that can start now.
