A new study reveals that tropical temperatures in Northern Borneo, specifically within Gunung Mulu National Park, closely tracked Southern Hemisphere temperatures and atmospheric CO₂ concentrations over two glacial cycles. Using speleothem fluid inclusion microthermometry—a highly precise method based on the density of trapped water—the research reconstructed cave temperatures spanning 127,000 years, from 460 to 333 thousand years ago. The findings indicate that deglacial warming in this region was accompanied by relatively dry conditions, with temperature changes reaching amplitudes of up to 4.3°C between glacial and interglacial periods. Notably, the study also identifies a site-specific Antarctic amplification factor, suggesting stronger polar temperature responses compared to tropical regions.

Tulou, the distinctive circular or rectangular structures built by the Hakka people in Fujian Province, China, offer a unique lens into architectural innovation and collective identity. These multi-story buildings, characterized by sealed outer walls and continuous balconies, served both practical and defensive purposes, fostering tight-knit communities centered around shared courtyards. Beyond their architectural significance, Tulou represent a cultural phenomenon where communal living shapes strong group identities, making them a focal point for ethnological study. This article explores the lives of Tulou inhabitants, their challenges, and future prospects, providing insights into how these structures both reflect and reinforce Hakka cultural identity.

St Kilda, often perceived as a remote and culturally isolated UNESCO World Heritage Site, is not historically or archaeologically distinct from its neighboring island Pabbay. This study challenges the notion of St Kilda as an 'ultima Thule,' revealing that both islands were once managed as a single unit by the Macleod estate in the historical period. The research compares the two islands' post-medieval archaeological landscapes, highlighting how their narratives diverged in the 19th century due to financial strain and land clearance, leaving Pabbay overlooked despite its significance. By analyzing historical records and conducting recent surveys of Pabbay, the study argues that understanding St Kilda's broader context should begin with its closest neighbor, providing a more nuanced perspective on its cultural and archaeological heritage.
