In this image of human colorectal cancer cells, the glowing points represent the chemical activity of mitochondria. Mitochondria are tiny structures that convert the energy from food into a chemical form that keeps cells running. To produce this image, researchers used a genetically encoded, chemically sensitive dye that allows them to monitor the activity of mitochondria in real time.
