bit.ly/4evhaSR - fantastic defense of basic science. Pursuing seemingly esoteric knowledge is the engine of biomedical research. Despite myriads of basic discoveries sparking cures, we continue to defund curiosity driven research. Fund scientists to work on what they choose

@schvartzman.bsky.social and I wrote a perspective on how dynamic metabolite-protein interactions can shape cell biology, and the open questions this raises about the broad roles of metabolism. It was fun to dig into Zabala-Letona, Carracedo et al.'s story as an example of this! tinyurl.com/4tcnrydm

Precision from broad strokes: How the non-specific interactions of metabolites and macromolecules can regulate biology
In a recent article in Nature, Zabala-Letona et al.1 propose that polyamines—small, positively charged metabolites—regulate RNA splicing by electrosta…

All of NIH funding to Northwestern University is frozen. This pause includes noncompeting approved funding, new and competing grants with fundable scores. No reimbursements for money already spent have been received since March. This situation is rarely reported so please Please get the word out!

There are so many stories like this. A weird colony in a plate in the rubbish to penicillin, fly eyes to ras inhibitors, weird repetitive sequences in bacteria to CRISPR. We should have a daily column on how science made your life better. #fundscience

I was that woman! I have frequently told the story of how Jeremy responded after my second NIH rejection. He said, “Whatever you do, don’t stop spending. If you run out of startup, we’ll find more money for you.” I didn’t need it in the end, but knowing he had my back was huge. Thank you!

A patient reminded me of science’s power: 2 doses of immunotherapy and a fatal cancer GONE. Immunotherapy exists BECAUSE of basic research—work that can seem esoteric or wasteful. Before dismissing it, ask a scientist why it matters. Or ask the Nobel who discovered immunotherapy.
