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 …

The movement trajectories of organisms serve as dynamic read-outs of their behaviour and
physiology. For microorganisms this can be difficult to resolve due to their small size and fast …

Thin phytoplankton layers with vertically compressed structures found in stratified lakes and
coastal water bodies have been a hot-spot in marine science and fluid mechanics. Although …

We investigate the escape dynamics of oligochaeta Lumbriculus variegatus by confining
them to a quasi-2D circular chamber with a narrow exit passage. The worms move by …

Protists ubiquitously live in nature and play key roles in the food web chain. Their habitats
consist of various geometrical structures, such as porous media and rigid surfaces, affecting …

Cells have evolved efficient strategies to probe their surroundings and navigate through
complex environments. From metastatic spread in the body to swimming cells in porous …

Many classes of active matter develop spatial memory by encoding information in space. We
present a framework based on mathematical billiards, wherein particles remember their past …

Foams are a ubiquitous feature of marine environments. They can have major economic,
societal and ecological consequences through their accumulation on the shore. Despite …

The light environment controls the swimming of microalgae through a light-seeking and
avoiding behaviour, which is known as phototaxis. In this work, we exploit phototaxis to …

In this work, we report investigations of the swimming behaviour of Paramecium tetraurelia,
a unicellular microorganism, in micro-engineered pools that are decorated with thousands of …
