Salt Lake County, Utah's air pollution varies over the year, and at times it is the worst in the United States. The geography traps winter inversions and summertime smog throughout the Salt Lake Valley, but underserved neighborhoods -- and their schools -- experience the highest concentrations. A new study utilized a community-university partnership of nearly 200 PM 2.5 sensors through the Air Quality and U network and revealed persistent social inequalities in Salt Lake County schools.
Prior to the COVID-19 pandemic, in cities where bike-share systems have been introduced, bike commuting increased by 20%, according to a new UW study.
Corn cultivation spread from Mesoamerica to what is now the American Southwest by about 4000 B.C., but how and when the crop made it to other parts of North America is still debated. In a new study, scientists report that corn was not grown in the ancient metropolis of Cahokia until sometime between A.D. 900 and 1000, a relatively late date that corresponds to the start of the city's rapid expansion.
Study is one of the first to analyse the relationship between urban development and health in a low- or middle-income country.
A new global simulation model offers the first long-term look at how urbanization -- the growth of cities and towns--will unfold in the coming decades. The research team projects the total amount of urban areas on Earth can grow anywhere from 1.8 to 5.9-fold by 2100, building approximately 618,000 square miles.
Over the past several years, a collaboration at HLRS has been developing a digital twin of Herrenberg, a small city just outside of Stuttgart, Germany. The Herrenberg study has already provided valuable information for city planners and government officials in the state of Baden-Württemberg, and paves the way for improving the model to include additional kinds of data.
What kind of an effect do trees have on aerosol particle concentrations in cities? Modelling carried out at the University of Helsinki revealed that the air was cleanest on the street level with three rows of trees of variable height situated along boulevard-type city street canyons.
The coronavirus pandemic has highlighted just how reliant the United States and other countries are on Chinese manufacturing, with widespread shortages of protective medical gear produced there.
In 15 years, the share of self-driving passenger vehicles on Moscow's roads will exceed 60%. However, this change will not have a significant impact if personal vehicle travel is not reduced and car sharing services are not expanded. For the first time, HSE University researchers have assessed the effects of self-driving cars on the city. In their study, Alexei Zomarev and Maria Rozhenko lay out predictions for 2030 and 2035.
Detecting gender bias against robots was the original intent of a study that revealed two surprises: The gender bias didn't appear. In its place, people were predisposed to find robots mostly incompetent -- no matter the gender.
