Ground Penetrating Radar (GPR) surveys of the UNESCO-listed Painted Churches in Cyprus's Troodos region have uncovered preliminary evidence of buried monastic complexes and surrounding buildings, shedding light on lost architectural structures that once accompanied these 11th to 16th-century churches. The study, part of the IH-AT project, employed non-destructive techniques (NDT), including geophysical surveys, topographic mapping, 3D modeling, and art-historical analysis, to investigate subsurface features without excavation. While findings are still preliminary, they suggest the presence of buried structures that could significantly alter our understanding of these World Heritage Sites' historical context. Future excavations may validate these discoveries, offering new insights into the monastic life and urban planning of medieval Cyprus.

A high-elevation barrier formed by the Tian Shan and Pamir ranges in Central Asia around 12 million years ago (Ma) effectively blocked westerly moisture, creating a rain shadow that led to desertification in the northwestern Tarim Basin. This finding resolves a long-standing controversy about when hyper-arid conditions developed in the region. Researchers analyzed a continuous stratigraphic section from the southern Tian Shan foreland, combining detrital zircon data, stable isotope compositions (δ18Oc and δ13Cc), structural modeling, and magnetostratigraphy. The study revealed that westerly precipitation was present by 15 Ma but intensified desertification occurred at ca. 12 Ma, coinciding with tectonic deformation in the Pamir and southern Tian Shan. Post-7 Ma, rapid shortening and deformation isolated the study area as a piggy-back basin, decoupling local sedimentologic changes from global climate signals. This work underscores the dominance of tectonics over regional and global climate influences in active settings.

Research on the pearl whipray (Fontitrygon margaritella) in the Bijagós Archipelago, Guinea-Bissau, reveals that this species exhibits rapid growth, early maturity, and significant ontogenetic diet shifts. The study estimated size-at-maturity at 20.3 cm for males and 24.3 cm for females, corresponding to ages of 2.2 and 3.9 years, respectively. Diet analysis showed that all life stages primarily consumed crustaceans and polychaetes, with notable variations among young-of-the-year (YOY), juveniles, and adults. The findings contribute valuable data for the conservation assessment and management of this elasmobranch species and its related taxa.

A decade-long study reveals that while Eucalyptus saligna plantations outperform Grevillea robusta in growth and productivity, G. robusta could offer greater carbon sequestration potential if managed under optimal conditions. Conducted across two sites with distinct soil and climatic conditions in North Kivu, Democratic Republic of the Congo, this research assessed 20 E. saligna and 12 G. robusta plantations over three consecutive years using non-destructive inventories. Findings indicate that E. saligna is more productive, particularly at higher altitudes, while G. robusta shows promise for carbon credits due to its biomass and carbon stock characteristics. The study suggests mixed-species plantations with tailored silvicultural practices could simultaneously optimize wood-energy production and carbon storage, addressing the growing energy demands of disadvantaged communities near Virunga National Park. Optimal rotation periods were determined at 8 years for E. saligna and 12 years for G. robusta, emphasizing the need for long-term economic and sustainability assessments in this critical region.

This ethnographic study reveals how the Gulag persists as a contested site of memory in post-socialist Russia, despite its official closure. It explores the language of commemoration and the social phenomenon of memory creation, focusing on four historically significant regions: the Solovetsky Islands, Komi Republic, Perm region, and Kolyma. The research demonstrates how objects become heritage and how human needs for remembrance shape the preservation of the Gulag's legacy today.
