The bond-based adhesion model is a key step toward a realistic description of RBC-parasite interaction, which allows the investigation of more realistic scenarios and is relevant for other biological systems.
Motile interstitial T cells in live zebrafish access a broad range of length-scales due to long-lived cell-intrinsic variation in speed, and a coupling between speed and directional persistence.
Transient cell-cell contact of eukaryotic cells, called contact following locomotion, causes cell density segregation, and its high-density region traveled as a band within the disordered background.
A theoretical framework for the growth of microtubules quantifies the roles of geometry, mechanics, kinetics and randomness and provides a phase diagram for dynamic instability in these self-assembled polymers.
Collective responses of animals are generally controlled by complex biological mechanisms and in Caenorhabditis eleganscollective dynamics are purely controlled by physical parameters such as oxygen penetration and bacterial diffusion.
The forces that multicellular tumor aggregates exert on their environment lead to non-linear, scale-invariant tissue deformations far away from the tumor, which can be exploited to quantify its collective contractility.
A linear array of spectrin tetramers imparts mechanical stability to axons by allowing spectrin domains to unfold reversibly when an axon is stretched, thereby acting as tension buffers.
Nucleation, elasticity theory, and simulations were combined to construct a general phase diagram that elucidates the conditions for successful viral assembly and the key factors to prevent it.
Novel mechanisms for cellular centering and symmetry breaking involving persistent contractile actomyosin flows and their hydrodynamic interactions with the fluid cytosol are presented and studied using a minimal, reconstituted system.
Collapse of bacterial communities containing antibiotic-resistant and susceptible cells can be driven by increased population size or delayed drug exposure.
