A severe contamination pattern in the Gulf of Naples, driven by anthropogenic pressures, has been identified through multivariate analysis. The study, conducted to evaluate sediment contaminants before a submarine power pipeline installation, revealed distinct contaminant hotspots in Torre Annunziata and Capri, while also highlighting the influence of depositional basins on contamination trends. Using supervised techniques like PLS_DA, researchers effectively analyzed complex datasets from marine surveys, pinpointing key variability trends in quality indicators. This approach offers valuable insights for targeted follow-up monitoring, ensuring more precise environmental assessments in highly anthropized coastal areas.

Achieving net-zero greenhouse gas (GHG) emissions from municipal solid waste (MSW) is feasible for tourism cities like Nan and Luang Prabang by 2030, provided on-site waste sorting is prioritized. A study developed three waste management scenarios, incorporating sensitivity and benefit-cost analyses, demonstrating that all could meet net-zero targets with available technology. However, off-site sorting in Luang Prabang proved less viable under a carbon price of $28.42 per tonne CO₂ equivalent. Challenges include increasing on-site separation rates and raising public awareness, but the study outlines a clear pathway for similar cities to adopt sustainable waste management practices.

Recent archaeological research has revised the timeline for the construction of Roman walls in Hispania, debunking the long-held belief that these structures were predominantly built during Augustus' reign. Analysis of excavation data from various Hispanic cities shows that wall construction began in the 1st century BC and continued through mid-1st century AD, with notable advancements in defensive designs during the late 3rd to early 5th centuries. This later phase introduced ultra-semicircular or square towers, wider wall-walks (4-7 meters), increased height (10-12 meters), and reduced distances between towers, reflecting advanced military innovations. The study challenges previous assumptions about the chronology and purpose of these fortifications, providing a more nuanced understanding of Roman urban defense strategies in Hispania.
