Archaeological investigations at Trader's Cave, Niah National Park, have contributed to the understanding of late Pleistocene-late Holocene prehistory in insular Southeast Asia (iSEA). The study builds on the historical significance of the Niah Great Cave Complex, particularly the 'Deep Skull' discovered in 1958. While recent re-dating of Anatomically Modern Humans (AMH) at Lida Ajder in Sumatra has challenged its status as the earliest evidence, the Deep Skull remains a pivotal discovery for regional prehistory. The research employed direct uranium series analysis and Bayesian modeling to date skull fragments, placing them within the range of 35.2+2.6 ka or c39-30 ka (at 94.5 per cent probability). This study underscores the enduring importance of Trader's Cave in advancing our knowledge of human occupation and cultural evolution in the region.

Research at Umm Al-Jimāl, a UNESCO World Heritage Site in Jordan, reveals complex and interconnected forms of cairn burial practices spanning millennia. Excavations in the Jebel Qurma region demonstrate that Early Bronze Age cemeteries were later replaced by tower tombs and conical ring cairns during the Hellenistic and Byzantine periods, with recurring reuse of tombs indicating their enduring significance for both the deceased and living communities. Additionally, Umm el-Jimal's architecture, including pioneering water systems and densely packed churches, suggests its role as a key hub for hospitality along historic trade routes from Petra to Damascus. The study combines archaeology, epigraphy, and philology to uncover these insights.

A study of ancient ruins at Rehovot-ba-Negev, Israel, reveals evidence of seismic destruction from at least four earthquakes dating back to the 5th century A.D. through the 20th century. Features such as tilted walls, collapsed arches, and wall fissures indicate strong seismic activity with local intensities ranging from VIII to IX on the Mercalli scale. Post-earthquake repairs, including supporting walls and columns, further corroborate these findings. This research aligns with previous studies in nearby Negev desert cities, confirming the region's seismic instability along the Dead Sea transform fault, where strong earthquakes occur approximately every few hundred years.
