Mobile phone mobility data have transformed the study of human behavior, but demographic and behavioral biases can compromise their representativeness and distort population-level inference. Existing ...

Infectious disease transmission is shaped by patterns of human interaction, which adapt as epidemic conditions change. Capturing these context-dependent behaviors remains a fundamental challenge for e...

An analysis of 194,631 social science articles found causal overclaiming in 46% of cases, increasing over time. This language shaped reader interpretations; AI-generated summaries often amplified over...

The Trump administration has sent mixed messages on vaccinations against measles as cases have continued to climb.

Nitschke and colleagues use historical data and epidemiological modelling to examine evidence for the 1789 smallpox epidemic in Australia. Their results indicate a likely southeastern origin, high mor...

Here, by analyzing the exhibition history and auction sales of over 65,000 contemporary artists across numerous institutions, the authors show gender disparities in visual artist exhibition opportunit...

This Review examines the opportunities and challenges introduced by new datasets and computational techniques in urban crime research, and outlines future directions for leveraging these advances effe...

Visitation entropy, the Shannon entropy of an individual's distribution of visits across locations, is a widely used metric in the human mobility literature. Yet, its widespread use rests on assumptio...

Author summary Human mobility patterns play a crucial role in the spatial spread of infectious diseases, as pathogens move between communities through the movements of infected individuals. During the...

Author summary Early risk assessment for infectious disease epidemics requires estimating what happens when a pathogen emerges, or is introduced, in a population. The most common risk indicator is the...

A global analysis of more than 3,800 studies that involved over 10 million people shows that contact with nature reduces symptoms of anxiety and depression while promoting relaxation. The findings str...

Epidemic forecasting has become an integral part of real-time infectious disease outbreak response. While collaborative ensembles composed of statistical and machine learning models have become the no...

L’estimation de la taille réelle de l’étendue de l’épidémie, tout comme le risque de dispersion dans la région et au-delà, met les chercheurs au défi d’une flambée épidémique aux multiples inconnues.

The scientific claims drawn from LLM social simulations should be no stronger than the robustness audits that support them. Generative agents bring new expressive power to agent-based modeling, enabli...

This Review discusses global approaches to infectious disease analysis and modeling, focusing on federated methods and addressing long-standing challenges in data interoperability, equity and trust.

Socio-demographic factors influence social contact patterns and play a fundamental role in shaping the transmission dynamics of infectious diseases. However, compartment-based models of infectious dis...

Climate change and social health are deeply interconnected: climate impacts erode social conditions, while social disconnection weakens collective climate action. Strengthening social health is essent...

Significant and reassuring updates in the outbreak investigation

Past studies of Andes virus offer scant evidence on transmission risks, and have sparked debate

Past work has documented the importance of formal collaboration, particularly coauthorship, in increasing research productivity and innovation. How...

Urban planners need up-to-date, global, and consistent street network models and indicators to measure resilience and performance, model accessibility, and target local quality-of-life interventions. ...

Background In England, the burden of respiratory infections varies by ethnicity, contributing to health inequalities, but the role of additional demographic factors remains underexplored. We quantifie...
