Congress rejected massive cuts to US science budgets for 2026, but much of the money still isnβt flowing to researchers.
The culprit? The White House Office of Management and Budget (OMB) is quietly slow-walking the release of funds. π§΅π
Jack Smith: "My fear is that we have seen the rule of law function in our country for so long that many of us have come to take it for granted. The rule of law is not self-executing. It depends on our collective commitment to apply it."

How does PRMT5 link splicing to mRNA export?
Out in Mol Cell: by methylating Sm proteins, PRMT5 releases mRNAs that would otherwise remain trapped on chromatin.

EPIGENETIC HULK READY TO SMASH AGAIN! GET IN LOSERS!
#NIH is hanging by a thread. The #CDC has been decimated. #RFK Jr. and Russell #Vought are psychopaths--I don't say this frivolously--they are cold, calculating, inflicting violence on millions through public policy. It is where we are right now. These men are not normal. 1/
Weβre 7 months in, and βPentagon plans military deployment in Chicagoβ is a headline in the Washington Post. And because itβs city number three, weβre already numbing to it.
If you read this about any other democracy in the world, youβd conclude that it was well on the road to a dictatorship.
Situation on 14th St and W St. NW, with federal agents -- no specific agency identified -- pulling cars over for checks. They arrested a Black woman in this car.
BIG crowd of people shouting at police.
"Fuck you!"
"What is wrong with you!"
"You don't need to terrorize people like this!"
HHS Winds Down mRNA Vaccine Development Under BARDA WASHINGTON, DCβAUGUST 5, 2025βThe U.S. Department of Health and Human Services (HHS) today announced the beginning of a coordinated wind-down of its mRNA vaccine development activities under the Biomedical Advanced Research and Development Authority (BARDA), including the cancellation and de-scoping of various contracts and solicitations. The decision follows a comprehensive review of mRNA-related investments initiated during the COVID-19 public health emergency. βWe reviewed the science, listened to the experts, and acted,β said HHS Secretary Robert F. Kennedy, Jr. βBARDA is terminating 22 mRNA vaccine development investments because the data show these vaccines fail to protect effectively against upper respiratory infections like COVID and flu. Weβre shifting that funding toward safer, broader vaccine platforms that remain effective even as viruses mutate.β
Release from HHS: HHS will wind down its development of the mRNA vaccine development activities under the Biomedical Advanced Research and Development Authority (BARDA).
Shout out to the WSJ journalists who reported on Voughtβs impoundment by footnote, causing the White House to walk it back. Impact journalism!!
Why canβt cells live without PRMT5? Our new transformative work inspired and led by
@jacobroth13.bsky.social (who defends his thesis tomorrow!) shows that this arginine methyltransferase is critical for histone production and genome stability.

This feedback loop explains why PRMT5 is cell-essential: by coordinating histone supply, PRMT5 ensures proper chromatin assembly, genome integrity & cell proliferation. No PRMT5 = no histones = stalled growth. @JacobRoth13.

Mechanistically, soluble histone H4 accumulates at histone locus bodies upon PRMT5 inhibition, and H4 R3 mutants localize more robustly than WTβsupporting methylation-driven feedback at histone loci.
4/5
Inhibiting or knocking down PRMT5 triggers rapid histone mRNA depletion, histone protein loss & replication-associated nuclear abnormalities (micronuclei, Ξ³H2AX foci), directly linking arginine methylation to genome stability.
3/5
Using time-resolved nascent transcription profiling, quantitative proteomics & imaging, we show that PRMT5 is required to sustain histone mRNA transcription & histone protein synthesis during S-phaseβwhen demand for new histones peaks.

Powerful statement by Sen. Alex Padilla.
Please notice that anytime senators or representatives try to conduct oversight, theyβre blocked.
In this case, a sitting US senator was tackled to the ground and handcuffedβfor asking a question.
Where the hell has Chuck Schumer been on this?
For all my NYC Chromatin / Epigenetics / Gene Expression colleagues - the registration and abstract deadline for our Summer '25 symposium is this Friday. Attendance is free (lunch and coffee breaks provided), but we need you to sign up! See here: mailchi.mp/cbee4a4e6267...
Excited for this summerβs NYC Chromatin Club!
Grad students & postdocs: submit your abstracts for a chance to present a poster or talk. Come connect w/ fellow epigenetic New Yorkers!

That foundation of basic science, funded by the NIH and DoD/CDMRP, led us here: to a druggable AML vulnerability.
Basic science matters. So does federal funding. /end
This story began with our curiosity-driven work in Xenopus frogs and proteinsβstudying glutamate-glutamylation in basic chromatin biology of histone chaperone function. bit.ly/4j7uEnB and and go.nature.com/42GgDXW and bit.ly/3XVCrMJ /7
TTLL4 is a post-translational regulator of leukemia maintenance.
Itβs druggable. Itβs specific. And itβs a promising new angle in a challenging AML subtype.
This is exactly the kind of science made possible by federal funding. /6
We didnβt stop there:
Through biochemical and virtual screening, we identified TTLL4 inhibitors.
One compound, EN7, selectively impairs NPM1c AML cellsβwhile sparing wildtype cells. /5
In a Npm1c;NrasG12D/+ mouse model, Ttll4 deletion reduced leukemia burden and significantly prolonged survival. /4
