A finite element model analysis predicts that the Sydney Opera House will experience minimal structural impacts from creep and shrinkage over the next 30 years, with only a slight increase in strain (0.090%) and prestress losses (32.59 kN per strand) by 2050. This suggests a shift in conservation efforts towards addressing minor surface cracking and water ingress rather than large structural concerns. The study also highlights the potential of digital twin technology for future monitoring of unique historical buildings, offering a cost-effective solution for long-term time-dependent analysis. The research utilized linear static and quasistatic analyses to investigate the effects of dead and wind loads on the prestressed concrete ribs.

A novel approach to reinforcing the soil structures of historical underground sites, such as those found at Kyiv-Pechersk Lavra, has been demonstrated through combined numerical and experimental investigations. The study reveals that integrating basalt reinforcement—specifically flat frames and individual rods—into damaged soil layers significantly enhances structural stability under high humidity and aggressive environmental conditions. This method was validated using a full-scale model of the Far Caves' underground passage, tested over eight years at the Kyiv National University of Construction and Architecture. The findings suggest that this technique can restore the original state of historical structures while ensuring long-term functionality, offering a practical solution for preserving UNESCO World Heritage Sites with similar geological challenges.

In the hyper-arid Namib Sand Sea, microbial activity is primarily driven by nutrient acquisition rather than diurnal environmental stress. This groundbreaking metatranscriptomic study reveals that despite extreme desiccation, a diverse and active microbial community—dominated by Actinobacteria—thrives in these conditions. Contrary to expectations, chemoautotrophic carbon fixation, not photosynthesis, dominates carbon cycling in this ecosystem. The research also shows that soil nitrate is the main nitrogen source for microbes, with nutrient acquisition processes overriding diurnal stress responses as the key driver of microbial transcription. This challenges the long-held assumption that microbial activity in hyper-arid soils is minimal and highlights the resilience and adaptability of desert microbial communities.

Alarmingly high rates of undernutrition—affecting over 50% of children under five—were found among migrant construction workers' offspring in Ahmedabad, India. The study, conducted across five urban worksites between 2017 and 2018, revealed that stunting (40.5%), wasting (22.1%), and underweight prevalence (50.4%) were driven by intersecting factors: parental misconceptions about malnutrition, prolonged work hours disrupting childcare, inadequate breastfeeding practices due to worksite constraints, and limited dietary diversity. Qualitative methods, including interviews and participant observation, uncovered how socio-cultural norms, poor sanitation, economic hardship, and lack of healthcare access compounded nutritional deficits. This research exposes the often-overlooked vulnerability of migrant children in India's informal economy, urging targeted policies to address their unique nutritional needs.

Tidal waves, including storm surges and tsunamis, significantly impacted the Joseon Dynasty (1392–1910), particularly along Korea's southwest coastline, with peak occurrences during the rainy season (June–September). While storm surges had identifiable causes like typhoons and high tides, tidal waves were often attributed to divine punishment due to unclear mechanisms. These events caused widespread devastation—drowning victims, destroyed salt pans, flooded farmlands leading to salinity accumulation, starvation, and mass displacement—disrupting tax collection and economic stability. The Joseon government responded with relief efforts, tax exemptions for displaced populations, and long-term real-estate taxation of affected lands. Despite modern advancements, coastal regions like Gyeongju remain vulnerable to tsunamis, highlighting the need for improved preventive measures. This study synthesizes historical records to analyze tidal wave patterns, societal responses, and their lasting consequences.
