Embryonic fate-mapping approaches in zebrafish, Xenopus and lamprey illuminate the evolutionary origins of carotid body glomus cells and pulmonary neuroendocrine cells.
The firing rates of neurons in the grasshopper auditory system are surprisingly robust to changes in temperature, and cell-intrinsic mechanisms are sufficient to explain this temperature insensitivity.
Zebrafish mutants and human endothelial cell experiments reveal that GIPC family endocytic adaptors bind to the Semaphorin receptor PLEXIND1, a critical regulator of vascular development, to negatively modulate its signaling.
Pyro-sequencing of two genes involved in bacterial secondary metabolism provides new insights into the rich reservoir of biologically active small molecules found in environmental bacteria.
Mammalian primary sensory inner hair cells play an active role in auditory information processing, such that they show a preference for either timing or intensity coding.
