Killer T cells swarm around tumour targets by accelerating the recruitment of distant T cells, which upon arrival and target engagement augment the chemotactic signal in a positive feedback loop.

In medaka fish, the reduction of cystic proliferation of germ stem cells declines gametogenesis, reproduction success, and male sexual behavior, with a decrease of mating vigor.

A single-cell RNA-seq study examining gene expression profiles in neurons that underlie Drosophila reproductive behaviors shows males and females build sex-specific behaviors at the molecular-genetic level by overlaying sex-specific information on core gene expression networks.

The universal bacteria cell wall component peptidoglycan impacts the egg-laying behavior of infected Drosophila females by directly modulating the activity of few brain octopaminergic neurons.

Chronic excitation of the Caenorhabditis elegans oxygen-sensing neurons alters calcium homeostasis to accelerate the decline of neural plasticity with age.

Chronic stimulation with odors at naturally occurring concentrations only mildly impacts early stages of olfactory processing, suggesting a need to re-interpret prevailing models of how chronic odor exposure affects olfactory function.
