Cellular telephone games: coping with noise in biology

Living cells make crucial decisions --- whether to grow, divide, die --- based on environmental cues. The chemical networks which transmit and amplify these signals from receptors on the cell surface are like an elaborate game of telephone: with each stage of the transmission, information is lost through the random nature of the interactions. Communicating even a single bit of information through the tumult of the cell turns out to be strikingly difficult. How have cells evolved to cope with this noise? The answer to this question begins in an unusual place: a classified program to improve the design of anti-aircraft guns during World War II. My talk explores how ideas in physics and engineering arising from this wartime effort are now helping us understand noise filtering strategies in living systems.
