A fibrillin-related protein, FBN-1, is a key component of the apical extracellular matrix and prevents epidermal cell deformation by biomechanical forces during morphogenesis of the C. elegans embryo.

By driving the localized contraction of subcellular muscle regions, a single motor neuron reverses the flow of material in the Caenorhabditis elegans pharynx, a neuromuscular pump, converting feeding into spitting.
A coordinated tissue movement during C. elegans central nervous system internalization reveals a novel role for HMR-1/cadherin in maintaining cohesion, and extends the concept of neurulation beyond vertebrates.
Mendelian randomization suggests the possibility that the observational effects of obesity and related metabolic traits in head and neck cancer risk are overestimated.

When ancestral Xenopus returned to water ~170mya, they evolved a new method for producing courtship calls underwater without airflow, using vibrations that also preserve essential acoustic information on species identity.
Although sugar-sensing taste neurons typically promote feeding, a taste neuron in the Drosophila pharynx limits feeding via the IR60b receptor; thus, revealing a new element in the circuit logic of feeding control.
Multi-dendritic cibarium neurons in the fly pharynx sense mechanical force during swallowing by NOMPC, piezo, and Tmc, besides, these neurons interact with motor neurons to control food swallow.

In light of the mysteries underlying the biphonic nature of Tuvan throat song, information from multiple modalities is combined to explain how this remarkable phenomenon is achieved biomechanically.
Unique heterochrony in the cranial segments in bichirs triggers the early formation of their external gills, and might be informative about developmental mechanisms facilitating increased breathing capacity.
