Gene knockdown experiments in fruit fly pupae reveal the role of the signaling molecule 'dFrizzled2' in the development of a neural circuit that helps insects to fly continuously for extended periods.
New reconstruction methods are used to create a publicly available dense reconstruction of the neurons and chemical synapses of central brain of Drosophila, with analysis of its graph properties.
The central complex, a highly conserved insect brain region important for navigation, is characterized by a high degree of recurrence and a sparseness of output pathways.

Regeneration of oligodendrocytes in the cerebral cortex results in reorganization of the pattern of myelination, potentially impacting information processing within cortical networks in diseases such as multiple sclerosis.
The copy-and-shift mechanism modelled in the insect central complex facilitates multimodal navigation, providing a general computation model explaining flexible navigation behaviours.

A numerical model of malaria parasite adhesion to an erythrocyte shows that the original egg-like shape of merozoites is more robust than other shapes in negotiating various physiological conditions during the alignment process upon erythrocyte invasion.
Two evolutionary distant insect species share a common head direction circuit with subtle differences in neuronal morphologies that result in distinct circuit dynamics adapted to each species’ ecology.

Limiting cytoplasmic streaming contributes to maintaining spatial separation of the sperm contents from the female meiotic spindle after fertilization.
The opposing dopamine receptors Dop1R1 and Dop2R are both enriched around the pre- and postsynaptic sites of different types of neurons, including dopaminergic neurons, in the fly brain.
