Journal ArticleDOI
High-precision tracking of sperm swimming fine structure provides strong test of resistive force theory
TL;DR: This theory accurately predicts the complex trajectories of sperm cells from the detailed shape of their flagellar beat across different time scales, consistent with quantitative predictions of resistive force theory.
Journal ArticleDOI
Chemotaxis of sperm cells
TL;DR: It is concluded that sampling a concentration field of chemoattractant along circular and helical swimming paths is a robust strategy for chemotaxis that works reliably for a vast range of parameters.
Journal ArticleDOI
Sperm navigation along helical paths in 3D chemoattractant landscapes.
Jan F. Jikeli,Luis Alvarez,Benjamin M. Friedrich,Laurence G. Wilson,René Pascal,Remy Colin,Magdalena Pichlo,Andreas Rennhack,Christoph Brenker,U. Benjamin Kaupp +9 more
TL;DR: This work tracks sea urchin sperm navigating in 3D chemoattractant gradients using holographic microscopy and optochemical techniques and provides a conceptual and technical framework for studying microswimmers in3D chemical landscapes.
Journal ArticleDOI
Reactivating head regrowth in a regeneration-deficient planarian species
Shang-Yun Liu,Claudia Selck,Benjamin M. Friedrich,Richard Lutz,Miquel Vila-Farré,Andreas Dahl,Holger Brandl,Naharajan Lakshmanaperumal,Ian Henry,Jochen C. Rink +9 more
TL;DR: The availability of D. lacteum as a regeneration-impaired planarian model species provides a first step towards elucidating the evolutionary mechanisms that ultimately determine why some animals regenerate and others do not.
Journal ArticleDOI
Cell-body rocking is a dominant mechanism for flagellar synchronization in a swimming alga
TL;DR: Realistic hydrodynamic computations and high-speed tracking experiments of swimming cells are presented that show how a perturbation from the synchronized state causes rotational motion of the cell body, which feeds back on the flagellar dynamics via hydrod dynamic friction forces and rapidly restores the synchronization state in the theory.
