Perfect micro rings woven from muscle fibers
A biological model system that dead-ends in an “absorbing state”
Supplied with sufficient energy, a freight train would ride the rails as far as they go. But nature also knows systems whose dynamics suddenly turn into a kind of endless loop. Like in a hamster wheel, a train caught up in such a system would continue running, but without moving forward. Scientists from the Cluster of Excellence Nanosystems Initiative Munich have now succeeded in building a simple model system consisting of only three components to study the laws of such so-called absorbing states.
