Copenhagen, Denmark. Image © Kristijan Arsov via UnsplashPublished on September 08, 2026Global city rankings offer one way of looking at how urban environments support everyday life. The Economist Intelligence Unit's (EIU) Global Liveability Index evaluates 173 cities across stability, healthcare, culture and environment, education, and infrastructure, highlighting both long-term patterns and changes from one year to the next. In the 2026 edition, Copenhagen has been named the world's most liveable city for the second consecutive year, followed by Vienna and Melbourne. The Danish capital scored 98 out of 100 overall, receiving perfect scores in stability, education, and infrastructure. The global average remains unchanged at 76.1, with improvements in healthcare, education, and infrastructure offsetting continued declines in stability.+ 7 Western Europe remains the highest-scoring region, with an average liveability score of 91.7, while Asia recorded the largest improvement, rising by 0.3 points to 73.9. Nine Asian cities now rank among the top 20, driven in part by improved healthcare scores across Chinese cities following increased public investment.

AbstractConventional cholesterol liposomes have poor stability, rapid clearance, and toxicity. This study used Rg3 to replace cholesterol for constructing curcumin-loaded liposomes (PCRL) and evaluated their potential for enhanced hepatocellular carcinoma therapy. Curcumin-loaded liposomes were prepared with Rg3 (PCRL) and cholesterol (PCCL) via thin-film hydration. Physicochemical properties, protein corona, in vitro behavior, in vivo tumor targeting, antitumor efficacy, and biosafety were assessed in H22 tumor-bearing mice. PCRL exhibited smaller particle size, superior storage/plasma stability, and comparable membrane packing to PCCL. Protein corona analysis showed reduced adsorption of immunoglobulin-like and complement proteins, prolonging blood circulation > 24 h and enhancing tumor accumulation.

AbstractPleural effusion is a common clinical finding with heterogeneous causes, including infection, malignancy, heart failure, tuberculosis, pulmonary embolism and systemic disease. Because patients often encounter pleural effusion as an imaging finding rather than as a diagnosis, short-video platforms may shape early understanding, anxiety and care-seeking behaviour. Evidence on the quality of this content is lacking. We conducted a cross-sectional content analysis of publicly available pleural effusion–related short videos on Douyin and Bilibili. The Mandarin search term “胸腔积液” (pleural effusion) was entered on 15 May 2026 and the first 150 results returned under each platform’s default ranking were screened.
