Divya Choudhary @divyach.bsky.social · 11/02/20266/ 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. 100
Divya Choudhary @divyach.bsky.social · 11/02/20265/ 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. 100
Divya Choudhary @divyach.bsky.social · 11/02/20264/ 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 · 11/02/20263/ We argue that apparent noise often reflects hidden variables: measurable cell-, gene-, or environment-level states that can bias outcomes. 100
Divya Choudhary @divyach.bsky.social · 11/02/20262/ Phenotypic heterogeneity has long been framed as irreducible randomness. That framework has been powerful - but it’s not the full story. 100
Divya Choudhary @divyach.bsky.social · 11/02/20261/ With @maxencevincent.bsky.social, we ask: when single bacterial cells behave differently under stress, is it really just “noise”?
