Locomotion and transport of microorganisms in fluids is an essential aspect of life. Search
for food, orientation toward light, spreading of off-spring, and the formation of colonies are …

The physical characteristics of tumours are intricately linked to the tumour phenotype and
difficulties during treatment. Many factors contribute to the increased stiffness of tumours; …

Plasticity of cancer invasion and metastasis depends on the ability of cancer cells to switch
between collective and single-cell dissemination, controlled by cadherin-mediated cell–cell …

Just as in clay moulding or glass blowing, physically sculpting biological structures requires
the constituent material to locally flow like a fluid while maintaining overall mechanical …

The epithelial-to-mesenchymal transition (EMT) and the unjamming transition (UJT) each
comprises a gateway to cellular migration, plasticity and remodeling, but the extent to which …

Cell motion inside dense tissues governs many biological processes, including embryonic
development and cancer metastasis, and recent experiments suggest that these tissues …

Tissue, cell, and nucleus morphology change during tumor progression. In 2D confluent cell
cultures, different tissue states, such as fluid (unjammed) and solid (jammed), are correlated …

From coffee beans flowing in a chute to cells remodelling in a living tissue, a wide variety of
close-packed collective systems—both inert and living—have the potential to jam. The …

Cell migration is important in many biological processes, including embryonic development,
cancer metastasis and wound healing. In these tissues, a cell's motion is often strongly …

This review summarizes theoretical progress in the field of active matter, placing it in the
context of recent experiments. This approach offers a unified framework for the mechanical …
