How Congress can restore the independence of US science Members must go beyond reinstating US government research spending and re-establish decentralized governance at the National Institutes of Health and other agencies.

The most impt change at #NIH and to US science this year is bigger than grant cancellations— it’s how the agency is governed.

For 75 years NIH has been largely independent of presidential control. That’s changed this year. New piece from me and @nataliebaviles.bsky.social in @nature.com

One more thing- here, together with amazing human being, friend & stellar physician scientist Abby Xie, we identify a new function of the TCA cycle, which is citrate clearance, now online at @cellpress.bsky.social: www.cell.com/cell/fulltex...

Aspartate availability drives differential engagement of the malate-aspartate shuttle Brunner et al. report that malate-aspartate shuttle engagement is cell-state dependent and can be modulated by the availability of the amino acid aspartate. In differentiated cells, malate-aspartate s...

A big chunk of my postdoctoral work on cell-state dependent metabolism is now out at @cp-molcell.bsky.social: www.cell.com/molecular-ce... 1/

Over 600 New Yorkers attended our Virtual Town Hall today to advocate for state-based science funding! We were joined by researchers, patients, institutions, and elected officials. @amsnyc.bsky.social @nycures.bsky.social @uawregion9a.bsky.social

🦠🧍‍♀️From bacterial to human immunity.

We report in @science.org the discovery of a human homolog of SIR2 antiphage proteins that participates in the TLR pathway of animal innate immunity.

BREAKING: Scientists are staging a “science fair” in the lobby of a Congressional building to tell elected officials about the critical knowledge the US will lose because their research grants have been canceled.

A study from the #MarraffiniLab in @science.org shows that newly discovered weapons of bacterial self-defense take different approaches to achieving the same goal: preventing a virus from spreading through the bacterial population.

I'm excited to share our latest story from the
@lydiafinley.bsky.social lab, where we show that it's not just whether cells take up nutrients that matters, but how and where those metabolites are used. Out now in @naturemetabolism.bsky.social: rdcu.be/ejFTs 1/

Thrilled that my thesis work in @lydiafinley.bsky.social's lab is out in the world! We found that methotrexate targets a specific metabolic vulnerability in a particularly aggressive form of pediatric rhabdomyosarcoma. Thank you to everyone who contributed to this project over the years!

Our latest preprint identifies (targetable!) metabolic programs intrinsic to different cancer cell states in rhabdomyosarcoma, out just in time for @katrinaparas.bsky.social's thesis defense tomorrow!
