The research found hot spots of mercury contamination tied to specific power plants, highlighting the need for better energy production choices.
A new study published in the American Journal of Preventive Medicine found that adults' moderate to vigorous physical activity is linked to neighborhood characteristics such as residential housing density and connected streets. Most physical activity occurs within a 1-kilometer buffer zone around their homes.
Researchers found that a mix of purchasing options can significantly lower costs and increase available water, while avoiding supply failures during droughts. This hybrid approach combines the benefits of buying diverse stocks with water risk management.
The 'Dust Alert' sensor measures dust, pollen, and toxins in the air, providing real-time contamination levels and precise chemical composition analysis. This invention can help improve air quality, mitigate health risks, and provide critical information for urban planners.
A new study by the University of Montreal found that only 30% of children attending elementary school in Quebec walk or bike to school. The primary obstacle is urban sprawl, with parents often driving their kids due to safety concerns, despite walking being crucial for daily energy expenditure.
Futuropolis 2058 conference highlights the importance of social and intellectual capital in creating sustainable urban environments. Experts emphasize the need for long-term city planning, integrating work, live, and play elements, to enhance human interaction and connection.
Extra payments to private FFS Medicare advantage plans totaled $2.5 billion in 2008, with each of the 2 million beneficiaries paying an average of $1,248 more than traditional Medicare costs. The new legislation aims to reduce overpayments and slow enrollment growth.
A researcher at Arizona State University has created a 3D computational model to simulate crowd behavior in urban settings. The model takes into account individual characteristics and environmental factors, allowing city planners and public safety officials to explore 'what-if' scenarios and test hypotheses.
A study of 10 Northeastern urban forests found no common urban park plant complex, but shows that population levels impact native and nonnative species diversity. The research suggests that urban park managers should consider the ratio of native to nonnative species when implementing vegetation restoration projects.
Researchers found that individuals' body weight influences their preference for residential locations in sprawling counties. Personal attributes like gender, age, and marital status also play a role in this decision.
Researchers investigated cultivation, conservation, and restoration activities in UK urban areas, highlighting ecological diversity and social connections between people and nature. The study calls for a redistribution of expertise to tap local skills and knowledge in green space management.
Four New York City clinics improved primary care services for low-income patients by redesigning their systems using a learning collaborative approach. The initiatives achieved significant reductions in wait times, improved financial performance, and increased patient access.
Researchers found that urban areas can extend plant growing seasons by 15 days compared to rural areas. Urban heat islands also cause plants to bloom 3 days earlier in spring and last 8 days longer in the fall.
The policy of increasing payments to private managed care plans has added $2.75 billion to Medicare's costs in 2004, with benefits mainly going to urban plans that have more enrollees. Despite the increase, only 40% of Medicare beneficiaries can access a Medicare Advantage plan.
Researchers at Northwestern University found that leafy vegetables and herbs in Chicago residential gardens are highly likely to be contaminated with lead. The study's findings highlight the importance of testing soil lead levels and developing strategies to ensure safety for urban gardeners and their families.
A study by Arizona State University researchers found a strong correlation between income levels and plant diversity in urban areas. The 'luxury effect' suggests that higher-income neighborhoods have greater plant diversity, possibly due to the influence of wealth on landscaping choices.
The report recommends building disaster resilience into utility infrastructure, strengthening emergency response systems, and establishing constitutional legitimacy for disaster management. The authors aim to reduce the vulnerability of Caracas to natural hazards through innovative interdisciplinary approaches.
Researchers found that childhood exposure to nature leads to a greater appreciation of the outdoors and interest in environmental careers. This has implications for educators and policymakers, as it can increase support for land preservation and environmental conservation.
New Urbanism's core values focus on environmental and spatial aspects, such as compact living and reduced land consumption. The trend promotes mixed-income housing to achieve social equity goals, rather than community bonding.
A recent study by Penn State researchers found that urban forest fires have led to increased tree density of specific species in New York City's undeveloped parklands. In contrast, an old-growth urban forest in Cleveland, Ohio, has remained stable with no history of forest fires since 1935.
