||Primary source  abstract: "…[investigators] have developed a single assay medium for determining enzyme-kinetic parameters in yeast." Primary source  abstract: "Here, [investigators] present a glutathione-specific green fluorescent protein-based redox probe termed redox sensitive YFP (rxYFP). Using yeast with genetically manipulated GSSG [oxidized glutathione] levels, [they] find that rxYFP equilibrates with the cytosolic glutathione redox buffer." Primary source  abstract: "[Investigators] have constructed a new nanobiosensor that can perform time-resolved measurements of intracellular ATP in intact cells."
