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 🧪

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.

Citrate clearance is a major function of aconitase 2 in the canonical TCA cycle
Beyond its traditional role in supporting bioenergetic and biosynthetic demands, the canonical TCA cycle is also essential for nutrient clearance. When pyruvate oxidation and citrate production increa...

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...

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

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. Learn more: bit.ly/4dvmBij

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!
