Helical swimming is a ubiquitous strategy for motile cells to generate self-gradients for
environmental sensing. The model biflagellate Chlamydomonas reinhardtii rotates at a constant 1…

We present a framework for the study of disclinations in two-dimensional active nematic liquid
crystals and topological defects in general. The order tensor formalism is used to calculate …

Motility is an essential factor for an organism’s survival and diversification. With the advent
of novel single-cell technologies, analytical frameworks, and theoretical methods, we can …

Legged animals often coordinate multiple appendages for both underwater and terrestrial
loco-motion. Quadrupeds in particular, change their limb movements dynamically to achieve a …

Chlamydomonas cells move in mysterious ways, swimming forward and backward with
different ciliary waveforms, and changing direction in response to cues from light, gravity, and …

The behaviour of an active polar suspension in a fluid film is analysed in the vanishing
Reynolds number limit. We perform a detailed study of the transitions to spontaneously flowing …

We report on a one-year project that focused on outdoor learning experiences for learners 12
- 14 years of age in a woodland environment in the UK. We wanted to investigate the ways …

Helical alignment towards gradients in space and time is a ubiquitous mechanism by which
ciliated and flagellated organisms achieve deterministic reorientation in space. Here, we …

Eukaryotes evolved radically new ways to sense and respond to a constantly changing
environment. Even single-celled microorganisms display near-determinstic navigation towards …

We present a novel framework for the study of disclinations in two-dimensional active nematic
liquid crystals, and topological defects in general. The order tensor formalism is used to …
