The paper introduces programmable microactuators to study ciliary responses to local flows, finding phase-locking and frequency shifts in Chlamydomonas reinhardtii cilia.

This study shows how diatoms switch between one- and two-raphe contact gliding to modulate path curvature by dynamically altering cell-substrate contact sites.

The paper measures torsion and twist in axonemes of Chlamydomonas reinhardtii, finding co-rotation between cross-section and bending plane, indicating twist-torsion coupling.

The paper quantifies phase fluctuations in axonemes after dynein motor removal, showing increased oscillation precision with motor number and distinct roles for inner and outer arm dyneins.

This study identifies and characterizes raphid diatom-specific myosins in Craspedostauros australis, showing that only CaMyoB-D moves during gliding, suggesting a role in force generation.
