Actin pool controls the scaling of dynamic actin networks

The paper investigates how actin networks scale with cell volume by reconstituting dynamic structures in controlled environments and shows that monomer depletion and disassembly rates determine scaling behavior.

Fabrication of microcompartments with controlled size and shape for encapsulating active matter

The paper describes the fabrication of microwells for encapsulating active matter, enabling controlled studies of cytoskeleton dynamics and other cellular processes.

Filament transport supports contractile steady states of actin networks.

This study shows that actin network contractile steady states can be sustained by filament transport rather than assembly/disassembly in an in vitro system.

Balancing limited resources in actin networks competition

This study investigates how actin networks coexist under resource competition by using a reconstituted system, showing that protein turnover enables coexistence but intense competition favors stronger networks.

Two different cell-cycle processes determine the timing of cell division in Escherichia coli

The paper experiments with Escherichia coli to show that both chromosome replication and a replication-independent process can limit cell division, with balanced contributions in normal cells and shifted odds under perturbation.
