The hydrodynamic Euler-elastica: shape transitions in the dynamical buckling of elastic filaments in Stokes flow
Clément Moreau, Laetitia Giraldi, Hermes Bloomfield-Gadêlha
The buckling of elastic filaments in viscous fluids, ubiquitous in biological systems like flagella, microtubules, and DNA, has long been described by the static Euler-elastica. Ye…

Swimming by spinning: spinning-top type rotations regularize sperm swimming into persistently symmetric paths in 3D
Xiaomeng Ren, Hermes Bloomfield-Gadêlha
Sperm modulate their flagellar symmetry to navigate through complex physico-chemical environments and achieve reproductive function. Yet it remains elusive how sperm swim forwards…

Direct Measurement of Unsteady Microscale Stokes Flow Using Optically Driven Microspheres
Nicolas Bruot, Pietro Cicuta, Hermes Bloomfield-Gadelha +4
A growing body of work on the dynamics of eukaryotic flagella has noted that their oscillation frequencies are sufficiently high that the viscous penetration depth of unsteady Stok…
