Two stories about how individual cell decisions shape behavior across lineages and populations.

2.1/ Lineage-related E. coli begin swimming together. 2.2/ Inherited flagellar structures integrate transcriptional activity across generations. 2.3/ FlgM sharpens the switch to swimming, allowing relatives with similar flagellar expression to become motile together.

1.1/ A high colicin threshold gates lysis, ensuring each sacrifice releases a large dose. 1.2/ Division of labor benefits warfare in spatially structured, but not well-mixed, populations. 1.3/ Limiting sacrifice protects lineages from self-destruction.

Big congratulations to @sarandavies.bsky.social on publishing this work from her DPhil. A dogged and determined and brilliant young scientist. And we couldn't have done it without our wonderful collaborator - @divyach.bsky.social from the @uphoff.bsky.social lab. Big team effort 🫶

Excited to share our latest work with Guanming Zhang and @stemartiniani.bsky.social in @natcomms.nature.com, where we uncover universal long-range structure in three distinct noisy particle systems spanning soft matter and machine learning. www.nature.com/articles/s41...

Unveiling hidden variables in stressed bacteria
Noise in bacterial stress responses is often dismissed as mere randomness. While true stochasticity exists, much variation reflects hidden variables—cell state, history, and microenvironment—that are ...

6/ We also highlight modern toolkits to tackle this: microfluidic platform integrated with machine learning and live-cell imaging, single-cell transcriptomics, etc. letting us measure and predict how hidden variables shape single cell outcomes.

Divya Choudhary @divyach.bsky.social · 11/02/2026
5/ Not all variability is predictable. Some events, like spontaneous mutations, are truly random. But bacteria combine deterministic circuits with stochastic events, and the challenge is teasing apart the two.

Divya Choudhary @divyach.bsky.social · 11/02/2026
4/ Classic examples -oxidative stress response, and DNA repair - show that variability becomes structured once these hidden factors are considered.
100
Divya Choudhary @divyach.bsky.social · 11/02/2026
3/ We argue that apparent noise often reflects hidden variables: measurable cell-, gene-, or environment-level states that can bias outcomes.

Divya Choudhary @divyach.bsky.social · 11/02/2026
2/ Phenotypic heterogeneity has long been framed as irreducible randomness. That framework has been powerful - but it’s not the full story.

Divya Choudhary @divyach.bsky.social · 11/02/2026
1/ With @maxencevincent.bsky.social, we ask: when single bacterial cells behave differently under stress, is it really just “noise”? Read more @cp-cellreports.bsky.social : Unveiling hidden variables in stressed bacteria (doi.org/10.1016/j.ce...)

2/ Rapid and coordinated regulation of stress response genes is critical for survival in a changing environment. Using single-cell imaging of transcriptional reporters, we follow the bacterial stress response under continuous hydrogen peroxide treatment.
