Self-organization of mortal filaments and its role in bacterial division ring formation
Filaments in the cell commonly treadmill. Driven by energy consumption, they grow on one
end while shrinking on the other, causing filaments to appear motile even though individual …

Active Screws: Emergent Active Chiral Nematics of Spinning Self-Propelled Rods
D Banerjee, R Alert - arXiv preprint arXiv:2410.12263, 2024 - arxiv.org
Several types of active agents self-propel by spinning around their propulsion axis, thus
behaving as active screws. Examples include cytoskeletal filaments in gliding assays …
