Researchers found that black and turkey vultures ingest more plastic in landscapes with more developed landcover and higher densities of commercial food providers. They may eat plastic thinking it's nutritious bone fragments or intentionally to collect bulk for vomiting up indigestible parts of carrion.
Research from the University of Kansas shows that families in Washington D.C.'s school choice policy are making choices that perpetuate segregation. Despite having more opportunities for integration, white families are returning to city centers and using tactics such as gaming the lottery system to secure spots in desirable schools.
A new model shows that encampment sweeps, bans and move-along-orders contribute to 15-25% increase in deaths among people experiencing homelessness over a 10-year period. Involuntary displacement is linked to increased overdose deaths, hospitalizations, injection-related infections and hindered access to medications.

A new study found that people in highly walkable neighborhoods are more likely to engage in adequate physical activity and have lower BMIs, but the association differs among Black, Hispanic, and Asian populations. The study highlights persistent inequities in physical activity due to systemic racism and policy barriers.
A new study estimates that urban heat islands cause 6,700 premature deaths annually in European cities, with increasing tree cover up to 30% reducing temperature and mortality rates. Cities with high excess heat-mortality rates can benefit most from this measure.
A modelling study suggests that increasing urban tree cover to 30% could decrease deaths from higher summer temperatures by a third.

The study also revealed that rural MSM perceived themselves as less susceptible to the disease and had lower intention to be vaccinated.
A new study by Boston University School of Public Health and the University of Washington School of Social Work found a consistent relationship between higher temperatures and higher risk of shootings in 100 of the country's most populated cities. Nearly seven percent of shootings can be attributed to above-average daily temperatures.
The Aztecs tracked seasonal variations in weather by watching the sunrise against the peaks of the Sierra Nevada mountains. Their agricultural system accurately fed a population of up to 3 million people before the Spanish arrival.
A study published in PLoS Genetics reveals the mechanism by which a selfish gene in yeast, wtf4, enables its function using a poison-antidote strategy. This strategy involves the production of poison protein that can kill spores, but is countered by an antidote protein produced only by those spores that inherit the drive allele.
The City of Tempe and Arizona State University have developed a unique partnership to track COVID-19 using wastewater-based epidemiology, providing early warning data for municipalities. The system has been shown to reliably predict SARS-CoV-2 levels in city ZIP codes up to 11 days ahead of clinical testing results.
A team of researchers conducted laboratory experiments and online surveys to study the perceived annoyance of impact sounds. They found that thudding sounds created by people walking barefoot are not captured by current standardized performance metrics, which may lead to improved guidance for architects and building code developers.

Research finds LA mountain lions are avoiding burned areas but crossing roads and traveling longer distances to find resources. The population is increasingly at risk due to habitat loss and human-wildlife conflict.
A study found that students who moved to a new school location reported significantly less delinquency after the shift, with fewer delinquent friends and less unstructured socializing. The transition to a new academic setting might reduce levels of juvenile delinquency in the long run.
New TOD index assesses development potential around transit nodes, ranking stations for their commercial diversity, walkability and land-use vibrancy. The study identifies areas suitable for residential growth, advising developers on informed urban planning.
The study found that higher population density was associated with fewer steps taken by patients, more sedentary time, and worse exercise capacity. Longer pedestrian street lengths were associated with more steps and less sedentary time, while steeper terrain was linked to greater exercise capacity.
The CityAccessMap tool assesses urban infrastructure distribution and identifies areas for improvement, helping policymakers address socio-economic disparities. Disadvantaged communities face lower access to urban services, which can hinder social mobility and exacerbate inequalities.
Climate change threatens societal capacity, leading to governance failures and basic necessities shortages. The authors propose three collapse scenarios: direct effects, indirect impacts on trade and international cooperation, and decreased adaptability.
