| On the cover: In recent years, driven by the new round of scientific and technological revolution, the transportation industry is undergoing unprecedented and significant changes. Emerging transport vehicles include autonomous vehicle and flying car. Some innovative operational modes appear, like Mobility as a Service and shared mobility. Meanwhile, advanced informatics technology, such as Artificial Intelligence and the Internet of Things, is also joining the way to make a better traffic. All of the progress has facilitated the emergence of Advanced Urban Aerial Mobility, a new paradigm for future transportation. The system is based on providing high-quality services as its core and the principles of energy-saving and environmental protection, making urban travel more enjoyable. This common scene in science fiction is no longer far-reaching. |

GRAPHICAL ABSTRACT
The Hawaiian-Emperor seamount chain has shown two subparallel geographical and geochemical volcanic trends, Loa and Kea, since ¡«5 Ma, for which numerous models have been proposed that usually involve a single mantle plume sampling different compositional sources of the deep or shallow mantle. However, both the dramatically increased eruption rate of the Hawaiian hotspot since ¡«5 Ma and the nearly simultaneous southward bending of the Hawaiian chain remain unexplained. Here, we propose a plume-plume interaction model where the compositionally depleted Kea trend represents the original Hawaiian plume tail and the relatively enriched Loa trend represents an emerging plume head southeast of the Hawaiian plume tail.
