Irreversible Dynamos in Butterflies

We study the propagation of information in a network in the presence of permanent faults, to detect the patterns of initial faults which may lead the entire system to fail. Such patterns, called dynamos, have been already studied in diierent contexts and topologies, and under diierent laws of fault propagation. In our model each node assumes a new state according to the majority of the states o...

Intimidating butterflies.

Many butterfly species feature two or four conspicuously coloured eyespots on their wings; the most commonly heard explanation for these markings is that they are used to intimidate predators. However, this explanation has stood, until recently, on the flimsiest of empirical foundations. Now, Adrian Vallin and colleagues have demonstrated empirically the effectiveness of these signals in dissua...
