Myxobacteria are social microbial predators that use cell–cell contacts to identify bacterial or
fungal prey and to differentiate kin relatives to initiate cellular responses. For prey killing …

Plasmodium sporozoites are the crescent-shaped forms of malaria parasites injected from
the salivary glands of mosquitoes into the skins of their vertebrate hosts. To proceed towards …

We study the collective dynamical behavior of active particles with topological interactions
and directional reversals. Surprising phenomena are shown to emerge as the interaction …

Many bacteria inhabit thin layers of water on solid surfaces both naturally in soils or on hosts
or textiles and in the lab on agar hydrogels. In these environments, cells experience …

Emergent phenomena pervade the biological world. These phenomena come about due to
interactions between the constituent units of a larger whole in contexts ranging from cells …
