Excavations at Site 1, one of the largest megalithic jar sites in Laos, have revealed evidence of secondary burial practices dating from the 8th to 13th centuries. This confirms that multiple individuals were interred in shared mortuary contexts, providing new insights into ritual practices at UNESCO World Heritage-listed Plain of Jars. The research, conducted by a Lao/Australian team, builds on previous studies and employs archaeological methods to analyze burial patterns and contextualize the site's significance within broader historical and cultural frameworks.

A study on the clouded leopard (Neofelis nebulosa) in Manas National Park, India, reveals critical insights into its population density and habitat use. Researchers estimated a low population density of 1.73 individuals per 100 km² and a relative abundance index of 0.18 per 100 trap-nights, indicating a vulnerable status. The study found that the availability of small prey species and primary forests significantly influenced clouded leopard habitat selection, emphasizing the conservation importance of these elements. Additionally, the research observed high temporal overlap (> 0.70) with distinct activity peaks among sympatric carnivores but no spatial co-occurrence pattern. This work contributes valuable data to our understanding of the mainland clouded leopard's population and behavioral ecology in Manas National Park.

The National Palace of Pena, a UNESCO-listed cultural landscape in Sintra, Portugal, faces significant security and safety challenges due to its unique natural environment. A study highlights that Parques de Sintra - Monte da Lua (PSML), the managing entity since 2007, has developed an Integrated Strategic Territorial Planning through collaboration with Civil Protection bodies and stakeholders. This approach establishes sustained protocols for territorial management while implementing a Conservation Plan for Built Heritage, focusing on maintenance, space usage rules, and performance evaluation. The study underscores the importance of international principles, ethical guidelines, and cost-effective methodologies in preserving such heritage sites, offering a model for balanced security and conservation efforts.

Historical records and archaeoseismological analysis reveal two devastating earthquakes that struck the ancient city of Qalhat, Oman, over 300 km from active plate boundaries. The first earthquake, estimated to have a magnitude of Mw 5.5 in 1497 AD, caused significant damage (intensity VII) but was repaired. A second, far more destructive quake (magnitude Mw 6.5–7.0, intensity X-XI) between 1580 and 1592 left the city in ruins, from which it never recovered. The study suggests that the Tiwi Fault or Qalhat Fault may have been responsible for these seismic events, challenging the perception of Arabia's interior as earthquake-free.
