    Fluorescent sensors that are responsive only in a specific subcellular location have remained elusive. Now, a chemogenetic sensing platform has been developed to sense glutathione in a user-defined organelle of interest. These tools enable quantitative studies of subcellular glutathione homeostasis using visible or near-infrared wavelengths.

    Cancer stem cells are typically refractory to conventional treatments. Now, an unprecedented mechanism has been discovered by which salinomycin and derivatives can sequester iron in lysosomes leading to cytoplasmic iron depletion and the subsequent production of reactive oxygen species that are lethal to the cell. This discovery of the importance of iron in cancer stem cell maintenance provides an opportunity for developing new therapeutics.
