Perfect micro rings woven from muscle fibers: A biological model system that dead-ends in '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 ...
