Meet Gerty Cori, the Nobel-winning biochemist who uncovered how the body stores and consumes sugars

Cori's work determined glycogen storage "disease" had several subtypes, each with a unique molecular cause

Nuclei of untransfected neurons are seen in the background (blue). The neuron in the center (yellow) contains an abnormal intracellular accumulation of huntingtin called an inclusion body (orange).
