However, effective mitigation has been limited by the absence of nationwide, fine-grained measurements of last-mile emissions. Here, using 14 billion orders and location data from 1.9 million couriers, we estimate last-mile delivery emissions across 365 Chinese cities. We find that order growth does not translate proportionally into emissions: an 83.5% increase in orders from 2023 to 2024 resulted in only 31.3% additional emissions. While larger cities produce higher total emissions, smaller cities show per-order emissions up to four times greater, driven primarily by lower delivery efficiency shaped by urban density. Mitigation simulations suggest that emissions could be reduced by up to 84.2%. These findings advance understanding of how e-commerce interacts with urban systems and reveal actionable pathways toward more efficient and sustainable urban logistics. While e-commerce greatly enhances convenience for urban consumers, it also contributes to rising last-mile delivery emissions. By estimating emissions across 365 Chinese cities, this study identifies pronounced city-level differences in emission intensity and reveals substantial opportunities for mitigation.","PeriodicalId":501700,"journal":{"name":"Nature Cities","volume":"3 5","pages":"458-466"},"PeriodicalIF":0.0,"publicationDate":"2026-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147979449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research attributes this trend to national top earnings growth or globalization but has left unanswered how national and local top earnings growth coincide and why this phenomenon occurs in cities less central to the global economy. Here we show that earnings growth in finance since the 1980s has concentrated top earnings in the few cities where financial market jobs cluster. Using administrative linked employer–employee data for ten countries in the global north from 1989 to 2019, we show that this pattern extends beyond major global cities to smaller financial cities. Comparing financial cities with similar domestic cities shows that this contribution is not just a byproduct of scale or urban growth. We thus emphasize the role of urban sectoral specialization and the labor markets within these sectors in driving the spatial concentration of top earnings. Earnings growth in the financial sector concentrates top incomes in specific cities, not only in major global hubs. Using administrative data from ten countries, the authors show that finance accounts for 26–50% of top earnings concentration, driven by rent-sharing in financial markets.","PeriodicalId":501700,"journal":{"name":"Nature Cities","volume":"3 5","pages":"447-457"},"PeriodicalIF":0.0,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s44284-026-00407-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147979448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, urban wetlands also receive contaminated surface runoff and may become reservoirs of harmful contaminants, including related to our earlier efforts to safeguard health. Antibiotics are a public health mainstay, but overuse has promoted the spread among bacteria of genes enabling them to survive treatment. Here, by collecting and analyzing samples from 17 urban wetlands across China and comparing them with global datasets from natural lakes and urban raw sewage, we find these urban wetlands to be hotspots of antibiotic resistance genes (ARGs), with average abundances about nine times higher than in natural lakes and comparable to that in raw urban sewage. We further discover both human bacterial pathogens and indicators of the potential transfer of ARGs among bacteria (‘horizontal transfer’), suggesting viruses in urban wetlands carrying ARGs might facilitate their spread within bacterial communities there. We also find higher levels of economic development associated with lower ARG abundances, suggesting socioeconomic factors could also shape the geographical distribution of ARGs in urban wetlands, perhaps through associated improvements in sewer systems. These findings emphasize the importance of collecting and treating stormwater before its release into urban wetlands to safeguard wildlife and human health. Urban wetlands are popular with people and wildlife, providing recreation, flood control and habitat. This study finds that they are also popular with genes for resistance to antibiotics, viruses that spread these genes, and bacteria harboring them, showing the importance of treating stormwater before it ends up in these watery resources.","PeriodicalId":501700,"journal":{"name":"Nature Cities","volume":"3 5","pages":"405-415"},"PeriodicalIF":0.0,"publicationDate":"2026-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147979451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some argue such displays prompt withdrawal among Muslim immigrants and undermine their sense of belonging, yet rigorous empirical testing remains limited. Given this empirical gap, this study provides a causal test of the effect of in situ exposure to embedded Islamic symbols on Muslim immigrants’ place-based integration. We conceptualize place integration as a proximal, cue-driven person–environment process, reflected in approach-oriented behavior and attitudinal–perceptual attachment to place. We then evaluate the effect of public Islam using naturalistic field experiments and original surveys with Muslim immigrants in Paris and London. Using a purpose-built augmented reality mobile app, our experiments tracked participants’ movement along identical urban routes, randomly assigning exposure to either Islamic symbols (treatment) or non-religious cues (control) (NParis = 151, NLondon = 147). GPS-based behavioral data comprising walking pace, acceleration and brief remaining near the location, show that exposure to Islamic symbols increased approach-oriented behavior (dParis = 0.51, dLondon = 0.63, P < 0.05), accompanied by a parallel increase in self-reported place attachment. Corroborating survey evidence (NParis = 403, NLondon = 400) further indicates that everyday visibility of Islamic symbols in one’s neighborhood is positively associated with place attachment. The patterns hold in both Paris and London, despite their contrasting approaches to religious visibility, indicating that the effect extends beyond a single policy context. These findings have implications for the governance of religious diversity in urban public spaces in the context of immigration. Religious expressions in public urban spaces can be contentious, with competing policies reflecting different expectations about whether such expressions support or undermine immigrant integration. Field experiments and surveys among Muslim immigrants show that exposure to Islamic symbols increases place integration in both Paris and London, despite their contrasting regulatory approaches to religious visibility.","PeriodicalId":501700,"journal":{"name":"Nature Cities","volume":"3 4","pages":"359-370"},"PeriodicalIF":0.0,"publicationDate":"2026-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147733246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
