Where U.S. science has been hit hardest after Trump’s first year The Trump administration has slashed the number of grants from the National Institutes of Health, with far fewer focused on women, cancer and mental health.

Those of us doing research related to women’s health have been hit particularly hard by the govt’s sabotage of the NIH. I spoke to WaPo for this piece, as painful as it was to discuss the reality my lab is facing. www.washingtonpost.com/science/2026...

Our group just received a new R01 that was delayed by many months- it should have been awarded ‘25, like the curve below. This grant had the highest score we’d ever received (2%-ile), yet funding was uncertain. With the delay we had to lay people off. Very inefficient. And we are the lucky ones.

Trump picks qualified, normal health leader to head CDC; experts still cautious She's well qualified but will need to navigate RFK Jr.'s anti-vaccine agenda.

“Amid the search for a new CDC director, some well-qualified candidates sought promises of autonomy to be able to fire and hire staff and to keep science insulated from political influence.

Those candidates were not selected, sources told the Post.”

Trump’s CDC Pick Looks Solid. The Real Risk Is RFK Jr President Donald Trump has wisely sidestepped controversy by choosing former deputy surgeon general Erica Schwartz to lead the Centers for Disease Control and Prevention.

Erica Schwartz could fix the CDC — as long as she’s not blocked by higher-ups

Second-favorite part: From 16:30 when the soloist plays her own accompaniment

If you rarely listen to classical music, this is a good way to get (re)introduced. Shows how interesting classical music can be when you can both see and hear it.

My favorite part: minutes 11-13. Based on the activity map, seems to be the favorite of many others as well.

Mendelssohn: Violin Concerto in E minor | Julia Fischer, Dresden Philharmonic & Michael Sanderling
Mendelssohn: Violin Concerto in E minor | Julia Fischer, Dresden Philharmonic & Michael Sanderling YouTube video by DW Classical Music

Just came across this wonderful recording of the Mendelssohn Violin Concerto. Soloist Julia Fischer is absolutely amazing. The videography brings out every note and every instrument, better than having a front-row seat.

Plot showing GRFP awards by directorate shows a big dip last year and major increases for engineering and biology (though this only brings it back to parity with 2024).

Plot showing GRFP awards by directorate shows a big dip last year and major increases for engineering and biology (though this only brings it back to parity with 2024).

The NSF GRFP is now out! There are 2,599 awardees, which is the most ever—and a big shift from last year which initially halved awardees (1,000 awardees + an additional 500).

I've thrown together a plot to break down the changes by field.

At a glance, 2599 recipients - I think the highest total ever? And quite a few in the Life Sciences, which I know was a concern for many - Evolutionary Biology had twice as many recipients (38) as last year (19).

We're gearing up to generate iPSCs stably expressing ASAPs, and are compiling a list of potential users who might want these to study cell fate pathways for neurons or cardiomyocytes, or to perform drug screening.

If these would be useful to you, please message me in the chat

Below are examples of the multiple voltage recordings we performed in hIPSC-derived neurons (thanks to the Wernig and Sudhof labs), showing similar information as patch-clamp but in high throughput. And the subthreshold voltages would not be seen with MEAs or calcium imaging.

A fast and responsive voltage indicator with enhanced sensitivity for unitary synaptic events A remaining challenge for genetically encoded voltage indicators (GEVIs) is the reliable detection of excitatory postsynaptic potentials (EPSPs). Here…

Methods for high-resolution voltage imaging of hIPSC-derived neurons was reported in our 2024 Neuron paper on ASAP5 (which has the highest SNR in 1p or 2p imaging, in vitro and in vivo, among published GEVIs)

Fellow X-scientists! Curious who among you might want human iPSCs stably expressing ASAP-family green fluorescent voltage indicators.

Cardiomyocytes and neurons differentiated from these iPSCs can self-report voltage with <1-ms and <1-mV resolution by standard widefield imaging.

CDC delays publishing report showing covid vaccine benefits The acting CDC director cited concerns with the methodology, but the design has long been used to test vaccine effectiveness.

"The acting director of the Centers for Disease Control and Prevention (Jay Bhattacharya) has delayed publication of a CDC report showing the covid-19 vaccine cut the likelihood of emergency department visits and hospitalizations for healthy adults last winter by about half."

NIH Support for Early Stage Investigators in FYs 2024 and 2025 | Grants & Funding

We never got the press coverage of the drop in FY2024 because by the time it was known there were bigger stories to cover. But we went from a declining situation (at least when it comes to time-efficiency of grant-writing) to a disaster.

Note there was already a drop in FY2024 which ended 9/2024 under Biden

Don't know why exactly but it's consistent with anecdotal experience of tightening paylines even before the election, and the ever-decreasing appetite for risk and need for abundant "preliminary data" (more like definitive data)

That's per applicant, not application, and only for R01s or equivalent. Per-app rates were below 8% in most institutes, so the average applicant applied ~2x

The % drop was fairly uniform by career stage:
New 10.0% = 44% less
At Risk 16.9% = 37% less
Established 19.6% = 40% less
ESI 18.9% = 37% less

NIH funding rate per applicant dropped 38% in FY2025 vs 2022, from 27.1% to 16.7%

Here's a breakdown by career stage. Why FY2022 vs FY2025?
• FY2022 was first FY with budget passed and administered by Biden
• FY2025 budget was in CR until 3/15/2025, so budget and most grants were under the Trump WH

Roger's passing 10y ago was a loss not just for science but for society at large. Some of what plagues some fields today (the constant overselling and jockeying for attention) would likely be curtailed with just a few frank comments from him.

Roger, you are very much missed.
