From branches to loops: The physics of transport networks in nature

An international team of researchers described how loops, crucial for the stability of such networks, occur in transport networks found in nature. The researchers observed that when one branch of the network reaches the system’s boundary, the interactions between the branches change drastically. Previously repelling branches begin to attract each other, leading to the sudden […]

A detailed microscopic theory: Lifting the veil of topological censorship

Topological protection provides unprecedented robustness of physical phenomena against all kinds of perturbations; but in doing so, it exercises topological censorship by hiding all kinds of interesting and important microscopic information. Recent experiments have collected microscopic information precisely of the kind hidden by such topological censorship.
