Far from equilibrium dynamics of tracer particles embedded in a growing multicellular spheroid

This study shows that tracer particles in growing cancer spheroids exhibit sub- and super-diffusive behavior due to cell proliferation and apoptosis, without affecting cell dynamics.

Cell growth rate dictates the onset of glass to fluid-like transition and long time super-diffusion in an evolving cell colony

The paper studies collective cell migration in tumor evolution, finding that growth rate influences the transition from glassy to super-diffusive behavior and reveals super-diffusion's universality in non-equilibrium systems.

Protein Collapse is Encoded in the Folded State Architecture

The paper develops a polymer physics-based theory to assess protein collapsibility using contact maps, showing that beta-sheet proteins are more collapsible than alpha-helical ones and explaining the origin of multi-domain proteins.
