Understanding the characteristics of waterlogging in urban agglomeration is essential for effective waterlogging prevention and management, as well as for promoting sustainable urban development. Previous studies have predominantly focused on the driving mechanisms of waterlogging in urban agglomeration at a single scale, but urban agglomeration space has greater spatio-temporal heterogeneity, it is often difficult to fully reveal such characteristics at a single scale. Consequently, this study endeavors to explore the spatio-temporal evolution characteristics and underlying mechanisms of waterlogging incidents within urban agglomerations by adopting a multi-scale analytical approach. The results indicate that: (1) The waterlogging degree and high-density zones increase in the GBA, and the waterlogging points are spatially polycentric. However, the waterlogging point in Hong Kong is decreasing. (2) The influence of ISP and AI on waterlogging is dominant at all scales, followed by RE and Slope. ISP∩Slope and ISP∩RE are the key interactions for waterlogging. (3) The aggregation of waterlogging decreases with grid scale, and the influence of land cover factors on waterlogging increases with grid scale. Moreover, the findings at the grid scale outperformed those at the watershed scale, indicating that the grid scale is more conducive to the investigation of waterlogging in urban agglomerations. This research broadens our comprehension of the mechanisms behind waterlogging in urban agglomeration and provide references for policy decisions on waterlogging prevention and mitigation within urban agglomerations.

Background: Planetary plastic pollution poses a major threat to ecosystems and human health in the Anthropocene, yet its impact on biogeochemical cycling remains poorly understood. Waterlogged rice paddies are globally important sources of CH. Given the widespread use of plastic mulching in soils, it is urgent to unravel whether low-density polyethylene (LDPE) will affect the methanogenic community in flooded paddy soils.

Article Synopsis
- The study examines how the growth of impervious surfaces in urban areas like Shenzhen contributes to waterlogging issues, focusing on green space morphological spatial patterns (MSPA).
- MSPA allows for a deeper understanding of land use impacts at a micro level, identifying key visual characteristics that affect urban water management.
- Results suggest that improving the design of green spaces—while considering factors like "loop," "edge," and "core" structures—can significantly enhance their effectiveness in reducing waterlogging, providing valuable insights for future urban planning.

Background: Despite growing awareness of sex differences in inappropriate prescribing among older adults, including the initiation of problematic prescribing cascades, the impact of gender bias remains largely unexplored.
Objectives: We explored how a patient's sex and gender-related sociocultural factors influence physicians' prescribing decisions, potentially leading to prescribing cascades in older adults. A secondary objective was to explore whether and how physician sex affected prescribing decisions for female and male patients.

Article Synopsis
- Several studies have established a connection between subway and ambient particle exposure and negative health effects, like inflammation and vascular issues, but the combined impact of these pollutants with lipopolysaccharide (LPS) remains largely unexplored.
- The research focused on the health effects of iron oxide particles (found in subway dust) compared to urban aerosols and vehicle exhaust, finding that iron oxides are more harmful, causing greater endothelial cell damage and altering key vascular proteins.
- When iron oxides are combined with LPS, there's a notable increase in inflammation and immune responses in the body, indicating that subway particles may pose greater health risks than other types of urban pollutants.
