A figurine from Pit K9901 of the Mausoleum of the First Qin Emperor provides new evidence for the origin and development of contortion in ancient China. The study reveals that Western acrobatic traditions influenced Qin-Han contortion techniques, which were later adapted to local cultural contexts through continuous innovation. This challenges existing assumptions about the evolution of Chinese acrobatics and offers fresh insights into early East-West cultural exchange during this period.

A groundbreaking study reveals that intensely negative magnetic anomalies surrounding the Vredefort impact structure, South Africa, are primarily caused by metamorphosed banded iron formations (BIFs) at the base of the Witwatersrand Supergroup. These BIFs, rich in magnetite and garnet crystals, were rapidly exhumed during the 2019 ± 2 Ma impact event, cooling below the Curie temperature to acquire a thermal remanence aligned with Earth's 2.02 Ga paleomagnetic field. The research utilized bicycle-mounted magnetometer surveys along 340 km of transects and paleomagnetic analyses, distinguishing lightning-affected samples from those preserving the original paleodirection. Thermoremanent magnetization experiments estimated a post-impact paleofield intensity of 52 μT, providing critical insights into the structure's magnetic signature formation and the role of Bushveld-related metamorphism in magnetite crystallization.

Osogbo, Nigeria, stands out as the only city with a UNESCO World Heritage Site, the Osun-Osogbo Sacred Grove, blending traditional and modern urban development. A retrospective analysis reveals that while post-colonial infrastructure projects have bolstered its economic significance, unplanned growth threatens sustainability. The study highlights the decisive role of indigenous agencies in shaping urbanity and emphasizes the need for inclusive, participatory planning policies to combat urban sprawl. Synchronization among planning agencies is crucial, along with a master plan, to ensure Osogbo's sustainable future. Fieldwork data from 2024 supports these findings, offering operational policies to mitigate challenges posed by rapid population growth.
