Analysis of published studies reveals that flagellates and ciliates separately exhibit log-normal distributions of swimming speeds, and rescaling by the mean speed of each collapses them to a universal relationship.

Although courtship vocalizations are unique to each species, the basic architecture of the neural circuitries underlying this behavior is conserved among closely related species of frogs, suggesting behavior can diverge while utilizing the homologous neural network inherited through evolutionary lineage.

Learning to reach in the sensorimotor loop, and the required neural dynamics, can be potentially explained by simple principles.

Molecular profiling of annelid myocytes reveals that the last common protostome-deuterostome ancestor already possessed a dual musculature, with visceral smooth muscles ensuring digestion and somatic striated muscles ensuring locomotion.

PTEN mutations disrupt inhibitory GABAergic signaling, causing neurodevelopmental defects that can be mitigated by β-hydroxybutyrate, which activates DAF-16/FOXO and may offer a therapeutic approach for excitation/inhibition imbalances.

An integrative model of coordinated crawling in fruit fly maggots links neuromuscular dynamics to body-substrate mechanics in the presence of proprioceptive feedback.

Quantitative FRET imaging in moving C. elegans shows that stretch-unfolding of twitchin kinase occurs in the active muscle, whereby mechanical activity titrates the signaling pathway of this cytoskeletal kinase.

Volume-EM reconstruction of a whole-body desmosomal connectome including all muscles and their desmosomal partners in a Platynereis larva provides a detailed view of the organisation of the entire locomotor system in an animal.

Computational models of spinal locomotor circuits in developing zebrafish reveal how new movements can emerge during development through the integration of new spinal neurons and new connections.

A digital flesh model of the sail-backed dinosaur Spinosaurus was tested and performed very poorly in water, favoring the view of this dinosaur as a two-legged, wading ambush predator of large fish in shallow waterways and not an aquatic dinosaur.
