In this episode we hear about heat-seeking behaviour in mosquitos, mass spawning in coral reefs, social organization in ants, fear in rats and tissue regeneration in newts.
Enteroendocrine cells sense nutrients in the gut and regulate digestive physiology but are rendered insensitive following fat ingestion due to alteration of gut microbiota.
A combination of genetics, behavior and physiology demonstrate that cool and moisture sensing rely on overlapping combinations of sensory receptors in Drosophila.
The gustatory receptor PxylGr34 is tuned to the steroid plant hormone brassinolide and mediates the deterrent effects of brassinolide on feeding and ovipositing behaviors in Plutella xylostella.
The slope of the chemoattractant concentration gradient is a driving force for sperm chemotaxis, by coordinating the entrainment of information flow between sensing, signaling and motility.
Understanding how loss of CO2/H+ vascular reactivity affects respiratory control may facilitate development of treatments for breathing problems in this population.
Single-cell FRET measurements reveal large temporal activity fluctuations within this signaling pathway in Escherichia coli, caused by stochasticity of receptor methylation combined with allosteric interactions and slow rearrangements within receptor clusters.
