Researchers solve the seemingly impossible problem of using only a few measurements to find the first victim of a disease The way information percolates through networks is of ongoing fascination to increasingly diverse groups of people. That’s why physicists have developed a new science of networks to better understand what’s going on. The models they have developed can accurately describe how disease spreads through society, how gossip spreads through social networks and how malware spreads over the internet. In other words, given the location of the source and the structure of the network, they can accurately predict how information will spread. However, the reverse task of determining the source of information after it has already spread is much harder. That’s because most interesting networks are so big that it’s impossible to measure the state of every node.
