Lead levels in urban soil are declining but hotspots persist

A Duke University study found that while lead levels have generally decreased since the 1970s, they remain above safety guidelines near residential foundations and in areas with high traffic density. Regular soil testing is essential to mitigate these risks and encourage cities to act on this issue.

Pandemic boosts demand for postal delivery of abortion pill

Two studies published in Contraception found that telehealth abortion improves access to reproductive health services, particularly for low-income persons and those living in rural areas. The studies also showed that most patients prefer receiving abortion pills through the mail and interacting with healthcare providers via telehealth.

SMART evaluates impact of competition between autonomous vehicles and public transit

A Singapore-based study found that competition between autonomous mobility services and public transit can lead to increased profits, system efficiency, and benefits for the public. However, it may also result in uneven social costs, such as higher travel costs or longer travel times, especially for vulnerable groups.

People of color hardest hit by air pollution from nearly all sources

A new study models people's exposure to air pollution by race-ethnicity and income level, finding that exposure disparities among people of color and white people are driven by nearly all emission source types. The researchers found that air pollution disparities arise from a more systemic set of causes than previously understood.

Urban squirrels, how much are we disturbing you?

Research finds that urban squirrels' success rates increase with repeated solving of a novel food-extraction task, suggesting adaptability to urban stressors. The study also reveals that direct human disturbance is a major stressor, while green coverage and squirrel population size have less impact on problem-solving performance.

79% decrease in primary care visits, 56-fold increase in virtual care: COVID-19 pandemic

Researchers found a significant shift towards virtual care during the COVID-19 pandemic, with 71.1% of all visits being virtual, compared to 1.2% before the pandemic.

'Oasis effect' in urban parks could contribute to greenhouse gas emissions, ASU study finds

Researchers at Arizona State University found that urban parks experience a significant increase in evaporative losses during the night due to the oasis effect, leading to higher carbon dioxide emissions. This can have important implications for water conservation and greenhouse gas emission management in desert cities like Phoenix.

Study: Jumps in elementary school violence linked to increased student transfers

A new study finds that student exposure to violent crime in urban elementary schools is linked to higher transfer rates, particularly for less advantaged students. The study suggests that creating a safe school environment could reduce violence-related transfers and increase stability in enrollment patterns.

Air pollution, green space and built environment characteristics may influence body mass index durin

A large longitudinal study found that exposure to air pollution during early childhood may lead to an increase in body mass index (BMI), while living in areas with greater green space and a more favorable built environment mix may be associated with a decrease in BMI. The study analyzed data from nearly 80,000 children and suggested th...
