Molecular labeling, electrophysiology and calcium imaging have revealed a novel switching of neurotransmitter at the frog neuromuscular junction where motoneurons transiently release glutamate before acetylcholine at synapses on developing hindlimb muscles at the onset of metamorphosis.
Stunning new scan data of an enigmatic fish from the Early Devonian of Australia, Ligulalepis, is identified as a stem osteichthyan, specifically, as the sister taxon to the 'psarolepids' plus crown osteichthyans.
A discovery of two previously unknown, molecularly distinct fields of cardiac progenitors in zebrafish provides evidence for cardiac laterality prior to the emergence of cardiac septation and allows novel insights into cardiac development and disease.
A computational method is presented that quantifies the effect that specific bacteria in the gut have on the immune system and guides the design of therapeutically potent microbial consortia to cure auto-immune disease.
Selective synapse formation in a retinal motion-sensitive circuit is orchestrated by starburst amacrine cells, which use homotypic interactions to initiate formation of a dendritic scaffold that recruits projections from circuit partners.
The collective action of six transcription factors selects and activates the regulatory regions of the HSN serotonergic neuron effector genes constituting a signature that can be used for the novo identification of HSN expressed genes.
