A device dubbed the “mother machine” enables real-time observation of mutagenesis in single bacterial cells.
Researchers are looking at actin polymerization and calcium uptake in human cells to study mitochondrial division.

RAJARSHI CHAKRABARTI, GEISEL SCHOOL OF MEDICINE AT DARTMOUTH Actin polymerization and calcium signaling play an important role in division of mitochondria. To study this process in depth, researchers treated human osteosarcoma cells with a specific compound—ionomycin—to raise the calcium levels within them. This caused a rapid polymerization of actin filaments, quickly followed by an increase in mitochondrial calcium.
