Earth’s magnetic field is produced in the planet’s liquid iron outer core as it spins around the solid inner core, and protects the surface from harmful solar radiation. Its strength and structure have varied at different times throughout geological history. At certain periods, the field has weakened to such an extent that it was able to swap the positions of magnetic north and south, whilst geographic north and geographic south remain the same....

Park et al revealed large-scale associations between industries and people across the globe: (a) the large-scale organization of geo-industrial clusters in the labor flow network; each circle represents a geo-industrial cluster, with size proportional to its number of employees; the colors represent the highest-level community membership; (b-e) two examples of hierarchical sub-structures in the labor flow network are illustrated; each circle represents a firm and the bar charts show the reduction in industry and region entropy within the cluster as a proportion of the parent cluster’s entropy: (b, c) the organization of banking and financial geo-industrial clusters are affected more by industries than geography; (d, e) the geo-industrial clusters in U.S. Midwest and South region form strong geographical clusters.
