Researchers have discovered that urban areas experience a greater difference in wet bulb globe temperature between 0.5 m and 1.5 m above ground due to surface heat radiation, posing health risks to children and pets during extreme heat events. Total solar eclipses also alter atmospheric conditions and insect behavior, with some species...
A new study reveals that 25 of the 28 most populous US cities are sinking, with some areas subsiding at rates of over 5 millimeters per year. The primary cause is massive ongoing groundwater extraction, which can lead to stresses on infrastructure and buildings.
Researchers discovered how urban rat migration spreads leptospirosis, a deadly disease, and developed a novel technique for testing rat kidneys. The study used advanced molecular techniques to analyze DNA from 328 rat kidney samples collected from 17 sites in Boston, finding that 59 rats were positive for Leptospira bacteria.
A study analyzed per capita municipal expenditures and their correlation with population changes in small and medium-sized cities in Japan. The results revealed that prioritizing child welfare expenditures is a key strategy to sustain populations, while city planning expenditures on street maintenance and construction were also effective.
