This volume is based on presentations by world-renowned investigators who gathered at the 76th Cold Spring Harbor Symposium on Quantitative Biology. It reviews the latest advances in our understanding of metabolism and disease, including research on fat, exercise and rhythms; insulin resistance and sensitivity; lifespan, aging and cancer; regulation and dysregulation of metabolism; signaling and gene regulation; environment and sensing; metabolic reprogramming; clocks and intermediary metabolism; metabolism and cancer; and autophagy, timing and small RNAs.
