The phosphate starvation response network in a commensal yeast evolved to expand its downstream targets via changes in the main transcription factor's dependence on its co-activator, potentially altering the physiological response.

Phosphate starvation in rice induces widespread, but transient, modulation of DNA methylation near stress responsive genes that is independent from the RNA-directed DNA methylation pathway.

Genetic and biochemical analysis of two enzymes reveals that inositol pyrophosphate signaling molecules allow plants to sense and regulate cellular phosphate levels, and to take up more phosphate when needed.

Fluorescence lifetime imaging microscopy, paired with fluorescent, voltage-sensitive dyes, provides a method for measuring and quantifying membrane potentials of living cells.

IQ domain phosphorylation regulates calmodulin binding and myosin-1 function.

Genetics, in vivo imaging, and unbiased chemical biology screens reveal that Trpv6 functions as a cellular quiescence regulator and delineates a Trpv6-mediated Ca²⁺ signaling pathway maintaining the quiescent state.

Modulating the nutrient sensor TORC1 only in neurons in C. elegans is sufficient to regulate systemic longevity via inter-tissue signals that remodel mitochondria networks in non neuronal cells.

The ER transmembrane protein VMP1 is important for release of lipoproteins from the ER membrane into the ER lumen for secretion.

Threonine promotes sleep via down-regulation of metabotropic GABA transmission in the ellipsoid body R2 neurons that generate homeostatic sleep drive in Drosophila.

In a developing yeast colony, cells go from homogeneous states to spatially organized, specialized metabolic states, and the new metabolic states depend on resources produced by the original state.
