the potential for the phenomenon to occur in power transmission networks where power generation is decentralized. In 2012, an international team of researchers from Institut Néel (CNRS, France), INP (France), IEMN (CNRS, France) and UCL (Belgium) published in Physical Review Letters a paper showing that Braess's paradox may occur in mesoscopic electron systems. In particular, they showed that adding a path for electrons in a nanoscopic network paradoxically reduced its conductance. That was shown both by simulations as well as experiments at low temperature using scanning gate microscopy. Springs A model with springs and ropes can show that a hanged weight can rise in height despite a taut rope in the hanging system being cut, and follows from the same mathematical structure as the original Braess's paradox. For two identical springs joined in series by a short rope, their total spring constant is half of each individual spring, resulting in a long stretch when a certain weight is hanged; This remains the case as we add two longer ropes in slack to connect the lower end of the upper spring to the hanged weight (lower end of the lower spring), and the upper end of the lower spring to the hanging point (upper end of the upper spring). However, when the short rope is cut, the longer ropes become taut, and the two springs become parallel to each other; The total spring constant is twice of each individual spring, and when the length of the long ropes are not too long, the hanged weight will actually rise in height compared to before the short rope is cut. The fact that the hanged weight rises despite cutting a taut rope (the short rope) in the hanging system is counter-intuitive, but it does follow from Hooke's law and the way springs work in series and in parallel. Biology Adilson E. Motter and collaborators demonstrated that Braess's paradox outcomes may often occur in biological and ecological systems. Motter suggests removing part of a perturbed network could rescue it. For resource management of endangered species food webs, in which extinction of many species might follow sequentially, selective removal of a doomed species from the network could in principle bring about the positive outcome of preventing a series of further extinctions. Team sports strategy It has been suggested that in basketball, a team can be seen as a network of possibilities for a route to
