Active matter, which ranges from molecular motors to groups of animals, exists at different
length scales and timescales, and various computational models have been proposed to …

Locomotion and transport of microorganisms in fluids is an essential aspect of life. Search
for food, orientation toward light, spreading of off-spring, and the formation of colonies are …

Activity and autonomous motion are fundamental in living and engineering systems. This
has stimulated the new field of'active matter'in recent years, which focuses on the physical …

We review theoretical models of individual motility as well as collective dynamics and
pattern formation of active particles. We focus on simple models of active dynamics with a …

Infertility is a growing global health issue with far-reaching socioeconomic implications. A
downward trend in male fertility highlights the acute need for affordable and accessible …

In the past decade, the volvocine green algae, spanning from the unicellular
Chlamydomonas to multicellular Volvox, have emerged as model organisms for a number of …

Tracking an odour plume to locate its source under variable wind and plume statistics is a
complex task. Flying insects routinely accomplish such tracking, often over long distances, in …

Chiral active matter comprises particles which can self-propel and self-rotate. Examples
range from sperm cells and bacteria near walls to autophoretic L-shaped colloids. In this …

Morphogens, such as Decapentaplegic (Dpp) in the fly imaginal discs, form graded
concentration profiles that control patterning and growth of developing organs. In the …

We generalize the Vicsek model to describe the collective behavior of polar circle swimmers
with local alignment interactions. While the phase transition leading to collective motion in …
