How bacterial chemotaxis is performed is much better understood than why. Traditionally,
chemotaxis has been understood as a foraging strategy by which bacteria enhance their …

Most swimming bacteria are capable of following gradients of nutrients, signaling molecules
and other environmental factors that affect bacterial physiology. This tactic behavior became …

CD38 is a molecule that can act as an enzyme, with NAD-depleting and intracellular
signaling activity, or as a receptor with adhesive functions. CD38 can be found expressed …

The fascinating patterns of collective motion created by autonomously driven particles have
fuelled active-matter research for over two decades. So far, theoretical active-matter …

Immune responses rely on the rapid and coordinated migration of leukocytes. Whereas it is
well established that single-cell migration is often guided by gradients of chemokines and …

Rhizosphere microbes play critical roles for plant's growth and health. Among them, the
beneficial rhizobacteria have the potential to be developed as the biofertilizer or …

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 …

Multicellular systems, from bacterial biofilms to human organs, form interfaces (or
boundaries) between different cell collectives to spatially organize versatile functions,. The …

Highlights•Bacterial growth rate impacts on the expression of chemotaxis genes.•Most
chemoeffectors are of metabolic value.•Metabolic value of chemoeffectors has shaped their …

In active matter, particles typically experience mediated interactions, which are not
constrained by Newton's third law and are therefore generically non-reciprocal. Non …
