Our lab has just received an NIH R35 award, and we’re recruiting a postdoc to start at the end of this year or early next year! We use cryo-EM to uncover the structural basis of key chromatin events using native complexes isolated from human cells or reconstituted in Xenopus (frog) egg extracts!

Cartoon showing key challenges in evolutionary cell biology. This schematic illustrates four central challenges in the field: (1) integrating cell biology with evolutionary theory and experimental evolution, (2) bridging the genotype–phenotype gap, (3) identifying and developing new model systems, and (4) incorporating ecological context into evolutionary cell biology. Each quadrant highlights a conceptual hurdle that must be addressed to advance the discipline.
@gautamdey.bsky.social, @fritzlaylin.bsky.social, @alebenoit.bsky.social and @eelcotromer.bsky.social discuss how the field of evolutionary cell biology works to understand how cells evolve & diversify, highlighting current challenges & the future outlook.

Scientists in the @alushinlab.bsky.social figured out how cells build a structure that lets them migrate. Unpacking these “finger-like” protein bundles that protrude from cells may lead to novel treatments for #metastasis. #RockefellerScience #YearInReview

Organelles do NOT have a single uniform pH.
And if you think they must, because “protons diffuse fast,” this paper is for you.
A thread on why that assumption is wrong; and what we found instead. 🧵 1/n
