Exotic rheology of materials with active rearrangements
Aondoyima Ioratim-Uba, Tanniemola B. Liverpool, Silke Henkes
The flow of biological tissues during development is controlled through the active stresses generated by cells interacting with their mechanical environment in the tissue. Many dev…
Breakup of an active chiral fluid
Luke Neville, Jens Eggers, Tanniemola B. Liverpool
The nonlinear breakup dynamics of a strip of active chiral fluid is considered, and it is shown that the strip thickness goes to zero as a power law in finite time. Applying slende…
Dynamics of Wound Closure in Living Nematic Epithelia
Henry Andralojc, Jake Turley, Helen Weavers +4
We study theoretically the closure of a wound in a layer of epithelial cells in a living tissue after damage. Our analysis is informed by our recent experiments observing re-epithe…
Correlated cell movements drive epithelial finger formation
Sander C. Kammeraat, Yann-Edwin Keta, Paul Appleton +5
Epithelia form protective barriers in multicellular organisms. To maintain homeostasis, they must be able to regenerate and heal damaged areas. This occurs through collective cell…
The physics and mathematics of living and dying matter
Tanniemola B. Liverpool, Kristian K. Müller-Nedebock, Xichen Chao +1
We introduce and study a class of active matter models in which we keep track of fuel (stored energy) consumption. They are by construction, thermodynamically consistent. Using the…
Cyclically sheared colloidal gels: structural change and delayed failure time
Himangsu Bhaumik, James E. Hallett, Tanniemola B. Liverpool +2
We present experiments and simulations on cyclically sheared colloidal gels, and probe their behaviour on several different length scales. The shearing induces structural changes i…
