Hydrodynamics of soft active matter
TLDR
This review summarizes theoretical progress in the field of active matter, placing it in the context of recent experiments, and highlights the experimental relevance of various semimicroscopic derivations of the continuum theory for describing bacterial swarms and suspensions, the cytoskeleton of living cells, and vibrated granular material.

Rheology of active-particle suspensions.
TLDR
The phenomena of cytoplasmic streaming, elastotaxis, and active mechanosensing find natural explanations within the model of hydrodynamic velocity, concentration, and stress fields in a suspension of active, energy-dissipating particles.

Rafts: Scale‐Dependent, Active Lipid Organization at the Cell Surface
TLDR
This review critically examines evidence for the main tenet of the ‘raft hypothesis’, namely lipid‐dependent segregation of specific membrane components in the plasma membrane, and suggests conventional approaches to studying raft organization wherein membranes are treated as passive, thermally equilibrated systems are unlikely to provide an adequate framework to understand the mechanisms of raft‐organization in vivo.

Actomyosin dynamics drive local membrane component organization in an in vitro active composite layer
TLDR
Results show how local membrane composition can be driven by active processes arising from actomyosin, highlighting the fundamental basis of the active composite model of the cell surface, and indicate its relevance to the study of membrane organization.
