Emergent collective alignment gives competitive advantage to longer cells during range expansion

The paper shows longer bacterial cells gain a competitive advantage during range expansion through collective alignment, blocking shorter cells from resources.

Genetic mixing and demixing on expanding spherical frontiers

This study examines genetic mixing and demixing in 3D bacterial range expansions, showing sector formation and merging dynamics consistent with a modified 3D Eden growth model.

Motility mediates satellite formation in confined biofilms

The paper shows how satellite colonies form around biofilms in semi-soft agar, demonstrating that motility and matrix elasticity enable faster bacterial expansion while maintaining community interactions.

Tumor spheroids accelerate persistently invading cancer cells

This study shows that tumor spheroids create gradients that accelerate cancer cell invasion through a biased persistent random walk mechanism.

Single-cell tracking reveals super-spreading cells with high persistence in invasive brain cancer

The paper tracks single-cell migration in brain cancer spheroids and identifies super-spreading cells with significantly longer persistence than most cells.
