Check this out straight from the NIH website, acknowledging that multiyear funding was likely responsible for a 20% decrease in early stage investigators. And that it was expected. A strange approach for someone so committed to the next generation of scientists. grants.nih.gov/news-events/...

Thrilled that @stanfordmedicine.bsky.social Comms highlighted our work on epistasis in their Insights channel! 🧬💛🌟 Grateful to work with an incredible team: my postdoc advisor @euanashley.bsky.social, co-corresponding author Bin Yu, and co–first author Tiffany Tang. med.stanford.edu/news/insight...

A relatively random thread about the degrees of NIH Directors. Not surprisingly, almost all NIH Directors have been straight MD holders. However, there have been two MD-PhD holders (actually one PhD, MD and one MD, PhD, but no combined MD-PhD holders) 1/13

Super excited we made the cover of @natcardiovascres.nature.com! Work represents ADAR1 RNA editing within the vascular wall

Excited for a major milestone in our efforts to map enhancers and interpret variants in the human genome: The E2G Portal! e2g.stanford.edu This collates our predictions of enhancer-gene regulatory interactions across >1,600 cell types and tissues. Uses cases 👇 1/

Hard to understate how wonderful it is to see our manuscript in print today @natcardiovascres.nature.com. We discover ADAR1 to control dsRNA sensor MDA5 in atherosclerosis, creating a new paradigm of endogenous dsRNA sensing as a causal mechanism of disease. Let's get into it 👇 #RNAsky rdcu.be/eGEyu

I am tremendously excited to share our work revealing the epigenomic landscape of single vascular cells. We discover that enhancers are not only cell type but vascular site specific and regulate the genetic drivers of disease risk. Let's dive in! 🧬👇 #epigenetics www.embopress.org/doi/full/10....

Atul Butte died yesterday. The world lost a giant. A big bear of a man. With a huge smile. With love for everyone. With energy that could power a room. I loved everything about Atul. I loved how he was always happy. I loved how excited he was about science and helping people.

If you weren't angry enough already, here are the rates of non-competitive renewals through May. 4008 Non-competitive renewals were due to be funded in May. The total funded was 99! Some is due to terminations, but most is due to slow grant making due to DOGE review and other impediments. 1/2

The NIH represents incredible value for the US economy and for the people of the world. We need to safeguard its future and that of our students and trainees. @rachelkeranen.bsky.social and I share our thoughts in today’s LA Times. www.latimes.com/opinion/stor...

Senator Durbin noted that some (I believe Republican Senators) had indicated the US had been doing more than its share of biomedical research and it was time for other countries take a turn. I felt I had to interrupt to respond...

Delighted to share our latest work deciphering the landscape of chromatin accessibility and modeling the DNA sequence syntax rules underlying gene regulation during human fetal development! www.biorxiv.org/content/10.1... Read on for more: 🧵 1/16 #GeneReg 🧬🖥️

Even as someone who has followed everything going on at the NIH very closely, this story made my heart sink. I hope Americans watch this and see the impact of shutting down science. This effects everyone.

Tons of fun at our annual #MyHeartCounts 5K! Amazing event and the one time a year I remember that racing a 5K is….hard, lol. Hit my goal time and looking forward to next year! @stanfordmedicine.bsky.social

Please join us next Tuesday April 29th at 1 pm EST for our next Symposium on Precision Genomics: CRISPR and Single-Cell Technologies in Vascular Biology, featuring #AaronJames @bgcoonlab.bsky.social @chadweldy.bsky.social and moderated by @vsleekim.bsky.social ! Register here: tinyurl.com/yhcdr68a

Here is the formal announcement. Jay Bhattacharya and RFK Jr. need to explain. Who exactly are they trying to "make healthy?" www.whi.org/md/news/whi-...

Happy to be part of this NAVBO Symposium on precision genomics (Tues, April 29, 2025). Excited to present on the epigenomic landscape of single vascular cells-ranging from single cell, regulatory networks, and ML prediction of variant effect, so much to talk about! members.navbo.org/calendar-of-...

Sigh. This study claiming a lack of association between ApoB & plaque has blown up in the media with the typical podcaster/youtuber grifters jumping on it. Beyond the obvious (small N, non-randomized), here are a few reasons the study doesn't show what people claim 🧵: www.jacc.org/doi/10.1016/...

Thrilled to share the🥇paper from the lab @ahajournals.bsky.social.

From an operational security perspective, this is the highest level of fuckup imaginable. These people cannot keep America safe.

There are days in life that shake you. I’m shattered 💔 to share that I just found out that the US Government terminated my 2024 NIH Director’s Early Independence Award (~$2 million), threatening my long-promised assistant professor job at Columbia University & academic career... 1/🧵

Yeah nice work @shoaclarke.bsky.social and team! Great to see this out in print!

I am not going to call this a Bluetorial, because I do not want to sully that term (which, at least I, find joyful). Let’s call it a Orwellial.

Francis Collins, the NIH Director for 12 years, led the Human Genome Project and other NIH efforts for 32 years, resigned today. Key words from his resignation letter www.nytimes.com/2025/03/01/u...

Stanford's president has announced that the university is enacting a staff hiring freeze, citing NIH funding cuts to "indirect costs" of research, as well as a proposal to Congress to increase endowment tax universities pay. "Taken together, these are very significant risks to the university."

The Trump administration's efforts to slash research funding have US graduate students, postdocs and other early-career scientists fearing for their careers. Some might leave the country -- or abandon research altogether. https://go.nature.com/43ao2zq

Almost all grant-review meetings under Trump 2.0 remain suspended at the US National Institutes of Health (NIH), preventing the world’s largest public funder of biomedical research from spending much of its US$47 billion annual budget. https://go.nature.com/4gM6oW4

Proud to share this new pub from my lab - “Novel Therapeutic Approach Targeting CXCR3 to Treat Immunotherapy Myocarditis” www.ahajournals.org/doi/10.1161/.... Congrats to first authors Vivian Huang and Yin Sun. Our first foray into targeted therapy for this devastating autoimmune condition

Yes

Instead of cutting costs for working families, Donald Trump is slashing the federal investments that fund their lifesaving care, fuel their local economy, and lower their health care costs. It’s cruel, short-sighted, and will cost jobs and devastate millions of families.

This is what amounts to an ILLEGAL & indiscriminate funding cut for research centers everywhere. It will mean shuttering labs across the country, layoffs in red & blue states, and derailing lifesaving research on everything from cancer to opioid addiction. We all need to speak out to save lives.

Science is absolutely key to the US's success but this government's intention to now dramatically reduce the part of the federal grants that go to the university (in addition to the researchers; the "indirects") is like removing the unseen roots of a tree and expecting it to continue to flourish.

1. Today the NIH director issued a new directive slashing overhead rates to 15%. I want to provide some context on what that means and why it matters. grants.nih.gov/grants/guide...

Raining and 20+mph winds on the coast? Perfect for the SF half marathon! @stanforddeptmed.bsky.social Cardiology improving their VO2 max this morning. A sign from a spectator read “Seems like an ineffective way to warm up”, true very true
