A unified model for the dynamics of ATP-independent ultrafast contraction | PNAS

Cover image: Pictured is a colony of bell-shaped, ciliated protists attached to organic debris. Carlos Floyd et al. imaged and analyzed the kinematics of two ciliated protist species (Vorticella sp. and Spirostomum sp.) to model the fast, calcium ion-powered contractions of the protists’ myoneme protein assemblies. The resulting mathematical model reproduced experimental observations across species and demonstrated that myoneme contractions have three distinct operating regimes. The findings could provide insight into protozoan evolution and inform the development of fast, motile synthetic cells. See the article by Floyd et al., e2217737120.
