Microtubule polymerization tuned by macromolecular crowdant size and density

This study investigates how macromolecular crowding agents affect microtubule polymerization rates and filament dynamics through experiments and simulations.

Effect of Size Variability, Filamentation and Division Dynamics on Escherichia coli Allometry

This study examines how population statistics and division dynamics affect the surface area-to-volume scaling in Escherichia coli, finding exponents greater than 2/3 when variability is considered.

Emergence of flagella-like oscillations in single microtubules driven by collective dynein transport

This study shows that flagella-like oscillations in single microtubules can emerge from ATP-driven collective dynein transport without external forcing.

Cell size and shape regulation of E. coli determines surface area scaling with volume

This study quantifies surface area scaling with volume in E. coli under varying conditions and proposes a model explaining the observed scaling exponent deviations from the ideal 2/3 value.

Evolutionary divergence of anaphase spindle mechanics in nematode embryos constrained by antagnonistic pulling and viscous forces

The paper investigates spindle mechanics in nematode embryos, finding that spindle mobility is constrained by a tradeoff between cytoplasmic viscosity and pulling forces across species.

Effect of plant tubulin kinetic diversification on microtubule lengths

The paper investigates how kinetic differences in plant tubulin affect microtubule polymerization, finding that mung bean tubulin produces fewer and shorter filaments with distinct kinetic properties.

Dynein collective behavior in mitotic nuclear positioning of Saccharomyces cerevisiae

The paper quantifies dynein's role in nuclear positioning during yeast mitosis by modeling SPB mobility and estimating force requirements.

Asymmetric Cell Growth and Nucleoid Displacement in Escherichia coli

This study identifies asymmetric membrane growth and nucleoid displacement in E. coli, suggesting a link between growth asymmetry and MreB dynamics.

‘Switch-like’ transition from random to directed motility of microtubules by a yeast dynein

The paper investigates how yeast dynein motors transition from random to directed microtubule motility based on motor density and filament length, revealing a switch-like behavior in directionality.
