I'm on Capitol Hill watching NIH director Jayanta Bhattacharya testify to the Senate HELP committee. Thankfully I haven't been escorted out of this event (yet). Here's what I'm following. You can also watch live here: www.help.senate.gov/hearings/mod...

Aluminium is crucial to vaccines — and safe. Why are US advisers debating it? www.nature.com/articles/d41... by @heidiledford.bsky.social via @nature.com "You cannot just get rid of an adjuvant that works and is safe before you have something else that you know will be a good replacement."

Inspired by Fred Rogers, @nature.com asked readers to help us 'find the helpers' amid the crisis in American science. What emerged were inspiring stories of researchers, legal experts, data hounds and government scientists who are fighting the dismantling of the US research enterprise. 🧪🧵1/6

Often the news happens so quickly that there's little time for it, so we took a step back to talk about the stories of the researchers who have been fighting back against the Trump administration's assault on science. w/ @maxkozlov.bsky.social and @heidiledford.bsky.social

YES!!!! So happy to see @maxkozlov.bsky.social recognized for the total rockstar he is: casw.org/news/max-koz... So many more schmancy journalism awards in this guy's future.

NIH director Jay Bhattacharya posted on X: "No clinical trial has been delayed, nor has any participant been dropped from clinical trial. These are the facts." Malaria, tuberculosis, cancer trials abroad have all been on the chopping block, leaving participants stranded, I reported in this story.

After ruling the NIH grant cuts were illegal yesterday, Judge Young, a Reagan appointee on the bench since 1985, ended the hearing with a blistering 15-minute speech. I've cleaned up my notes — here are his remarks in full. 🧵

An NIH staffer reacts to today's ruling: "I'm looking forward to the day that we are so slammed with work trying to reinstate everything that we had to terminate illegally — I'll work 24/7 to make that happen if I can."

Barbara McClintock was born OTD in 1902. “I start with the seedling, and I don't want to leave it. I don't feel I really know the story if I don't watch the plant all the way along. So I know every plant in the field. I know them intimately, and I find it a real pleasure.” 🌱🐋🧪 #HistSTM #PhilSci

A lightning-fast, in-depth look into who RFK Jr selected for the vaccine advisory committee. One of whom was an expert witness against Merck's vaccine, despite RFK's stated reason of reducing conflicts of interest, per @reuters.com. Well done @heidiledford.bsky.social and @rfieldmouse.bsky.social

"US scientists who find themselves abruptly unemployed are turning desperation and defiance into fresh coping strategies and advice. But one thing is clear: whether they move abroad, pivot to other research areas or leave science altogether, their deep expertise is likely to be lost." 🧪

Check out this news story that @nature.com wrote describing our recent preprint where we tested our H5 mRNA vaccine in calves. The data look good and we are currently testing the vaccine in lactating cattle...more to come!

A US judge to govt lawyers defending the NIH's grant terminations: "I understand the administration is against DEI. Respectfully, I just don't know what you mean. This isn't a teasing question. There has to be some working definition. This is research to advance healthcare for all our citizens."

There are a lot of questions being asked about the awarding of a $500M grant to an #NIH team to develop a new (old) vaccine platform that could be used for a "universal" #flu vaccine. www.statnews.com/2025/05/03/n...

Affected by the foreign subawards policy? Help run clinical trials abroad on a project with a subaward? I want to hear how this policy impacts you. Send me a message on Signal at mkozlov .01 or email me at maxkozlov [at] protonmail [dot] com. You can stay anonymous.

BREAKING: NSF has frozen all grant funding, as of yesterday. It's unclear when they will resume funding awards, or why the pause has been put in place. www.nature.com/articles/d41...

NEW: An NIH policy coming in the next week will target — and at least temporarily stop — funding outside the US, threatening thousands of projects and collaborations on topics like infectious diseases and cancer. Some NIH staff have already been told to hold all subaward funds for foreign labs.

"Absent any official word, the contracts officer said, federal funders planned to act on the first decision to cut off support for the research."

Under this administration, it's difficult to know what will happen tomorrow. But these cuts to science will have long-term effects, so we tried to take a step back and consider the impacts in 5, 10 years. Reported with @heidiledford.bsky.social & Jeff Tollefson: www.nature.com/articles/d41...

After our story about the impact of funding cuts on early-career researchers, a reader contacted me: ‘Ahem. What about us soft-money PIs?’ Fair point. So here -- with special thanks to that reader and to all the researchers who've shared their personal stories with us -- is that story:

NIH, which began this week terminating projects studying long COVID, has reinstated the grants, after pressure from Sen. Todd Young's (R-IN) office, an HHS source tells me. Young had secured a commitment from RFK Jr that he'd continue funding long COVID research. Story by @thesicktimes.bsky.social

🚨 NIH sent out another data call, this time for projects "related to any form of censorship at all or directing people to believe one idea over another related to health outcomes… e,g., any contracts to promote COVID vaccine uptake," I'm told. These data calls have recently preceded terminations.

Even in 2025, some things still shock. Like the apparent selection of a long-time vaccine opponent who was disciplined & fined for practicing medicine without a license to conduct a new HHS study into whether there's a link between vaccines and autism. www.statnews.com/2025/03/26/r...

“Physicians at Covenant Children’s Hospital in Lubbock, Texas, say they’ve now treated a handful of children who were given so much vitamin A that they had signs of liver damage. Some of them had received unsafe doses of supplements for several weeks in an attempt to prevent a measles infection”

Travelling to the US as a scholar who studies disinformation, elections, and press freedom and who is on record speaking out in favor of science, facts, journalism and democracy is a dilemma. I spoke to @heidiledford.bsky.social @nature.com about this.

There were quite a few things that people told me that we just didn’t have room for in this story about how the US immigration crackdown is worrying scientists: www.nature.com/articles/d41... Here's a thread with a few of them:

Yay: Most postponed study sections have been rescheduled at this point. Yikes: To do this, CSR has scheduled *289* study sections from 03/24-05/16/2025. For comparison, there were only 96 study sections from 3/24-5/17/2024. And NIH still plans to RIF more staff. docs.google.com/spreadsheets...

PSA: if you're trying to read a recently posted news story from Nature, and you run into what looks like a paywall, it's almost always a "register with your email for free and you can read the story for free" thing. Even though it looks like a paywall.

“More trouble might be coming in the appropriations process: Vought’s 2023 proposal called for slashing the NIH’s budget…by more than 20%” Every $1 of NIH funding generates $2.46 in economic activity and contributed to 99.4% of approved drugs. Insane to indiscriminately slash the budget 🧪🩺
