Our new paper is out Cell Systems. We asked how a cell population copes with multiple environmental signals using E. coli chemotaxis as a model. Turns out they can process two signals independently using a single signaling pathway! sciencedirect.com/science/articl…

Introducing The Well: 15TB of standardized scientific simulation datasets compiled from various domains — a big step forward for the sciML community. Glad to be a small part of this big effort. #NeurIPS2024

A model describes how hair cells in the #cochlea enhance hearing sensitivity by supporting two distinct modes, showing how their collective activity creates a critically tuned cochlea. 🔗 go.aps.org/3W5aeC5

Bacteria navigate using flagellar motors. How do these motors respond to signals with a Hill coefficient >10? Yuhai Tu and I propose a new mechanism based on recent cryo-EM structures in which sensitive responses to chemical inputs arise from mechanics: arxiv.org/abs/2502.03290

Now out! Migrating populations of bacteria shape their own phenotypic composition to navigate through new environments. Awesome experiments by Lam Vo, Fotios Avgidis, Karah, Isabel, and Ravi. W/ Emonet Lab, Tom Shimizu AMOLF, and Barbara Kazmierczak pnas.org/doi/10.1073/pn…

Fungi made Earth’s land liveable by building networks that released nutrients locked in primordial rock and supplied those nutrients to plant roots go.nature.com/3QEwvn6

Have you ever wondered whether your favorite physical system might be a manifestation of Maxwell’s Demon? If you have, you’re certainly not alone! My co-authors and I have been wondering about this for a while now, especially for my favorite physical system: molecular machines.

I have openings for graduate students in SFU Physics, SFU Chemistry, or SFU Molecular Biology and Biochemistry. Check out davidsivak.com for our research interests!

New preprint out today: “Information Thermodynamics of Cellular Ion Pumps”. Led by talented undergraduate student Julián Jiménez-Paz, and working with David Sivak, we explore the thermodynamics of cellular ion pumps like the sodium-potassium pump.
