"Come on feel the noise," by Philip Ball. Nature Science Update,13 February 2001

Jose Vilar and J. M. Rubi have developed a mathematical model that suggeststhat adding more noise to noise may actually make the system less "noisy."Although the result appears to have general implications, the model dealsspecifically with fluctuations occurring in the electrical current in an arrayof ion channels. Ball's update is at http://www.nature.com/nsu/010215/010215-12.html.The research was published in Physical Review Letters, 86, pp. 950-3.
