Researchers Develop 'Urban Pulse' Metric to Measure City Metabolic Activity
Researchers from the University of Connecticut published a study in the Proceedings of the National Academy of Sciences introducing an "urban pulse" metric that measures cities' metabolic activity across six dimensions including demography, economy, infrastructure, environment, governance, and culture. The metric aims to capture dynamic changes within urban areas rather than just static outcomes like population growth or infrastructure expansion. This tool could inform both government policy decisions and individual choices about where to live or establish businesses.
A new study published in the Proceedings of the National Academy of Sciences proposes measuring cities' "urban pulse"—a quantifiable indicator of urban metabolic activity that reflects dynamic changes across multiple dimensions. Led by Zhe Zhu of the University of Connecticut, the research moves beyond traditional urbanization metrics that only capture static outcomes like completed buildings or road expansions. Instead, the framework tracks concurrent changes in demography, economy, infrastructure, environment, governance, and culture to reveal patterns of how cities actually function as living, adaptive ecosystems. The researchers suggest this approach could influence both top-down policy decisions from governments and bottom-up decisions from residents and business owners. Potential applications include helping people evaluate neighborhoods during house-hunting or assisting entrepreneurs in scouting business locations by providing real-time insights into urban vitality.
Limitations & open questions
The article does not discuss how the "urban pulse" metrics would be measured in practice, what data sources would be required, potential privacy concerns with collecting such granular urban data, or how the framework might apply differently to cities in developing versus developed nations.

New AI Framework Improves Evidence-Based Analysis for Muon Collider Research
Researchers have developed an AI system called agentic hybrid RAG that combines retrieval and reasoning techniques to help scientists find and verify evidence in muon collider research literature. The framework integrates both keyword-based and semantic search methods with AI reasoning to decompose complex queries and synthesize answers. This work addresses a growing need in high-energy physics for AI-assisted tools that can reliably navigate rapidly expanding scientific literature.
NASA Announces Four-Astronaut Crew for Artemis III Moon Mission
NASA named three U.S. astronauts and one Italian astronaut from the European Space Agency as the crew for Artemis III, scheduled to launch in 2027. The mission will conduct a docking demonstration in Earth's orbit and test moon landers from SpaceX and Blue Origin. The crew includes a veteran test pilot, a record-holder for longest U.S. spaceflight, and a first-time space flyer.
Rare Great White shark filmed in Mediterranean Sea between Tunisia and Sicily
A volunteer diver captured rare footage of a Great White shark in the Mediterranean Sea in May while working to document ghost fishing nets. The sighting is significant because Great Whites are thought to be near extinction in the Mediterranean due to overfishing. Conservationists hope the discovery will prompt governments to establish marine protected areas in the region.
