Growth-Induced Transitions in Viscoelastic Matter
Valentin Slepukhin, Oskar Hallatschek
Growth is a fundamental process in living systems. Although the stress-deformation response of growing materials is often described as either purely elastic or purely viscous, many…
Barrier-Free Microhabitats: Self-Organized Seclusion in Microbial Communities
Valentin Slepukhin, Víctor Peris Yagüe, Christian Westendorf +2
Bacteria frequently colonize natural microcavities such as gut crypts, plant apoplasts, and soil pores. Recent studies have shown that the physical structure of these spaces plays…
Dynamic sampling bias and overdispersion induced by skewed offspring distributions
Takashi Okada, Oskar Hallatschek
Natural populations often show enhanced genetic drift consistent with a strong skew in their offspring number distribution. The skew arises because the variability of family sizes…
Genetic drift in range expansions is very sensitive to density feedback in dispersal and growth
Gabriel Birzu, Sakib Matin, Oskar Hallatschek +1
Theory predicts rapid genetic drift during invasions, yet many expanding populations maintain high genetic diversity. We find that genetic drift is dramatically suppressed when dis…
Jamming by growth
Pawel Gniewek, Carl F Schreck, Oskar Hallatschek
Growth in confined spaces can drive cellular populations through a jamming transition from a fluid-like state to a solid-like state. Experiments have found that jammed budding yeas…
Fluid flow through packings of elastic shells
Pawel Gniewek, Oskar Hallatschek
Fluid transport in porous materials is commonly studied in geological samples (soil, sediments etc.) or idealized systems, but the fluid flow through compacted granular materials,…
