The Lancet Healthy Longevity: Residential context important factor in risk of COVID-19 mortality among older adults, Stockholm study suggests

New study of older adults (aged 70 or over) in Stockholm, Sweden, suggests older people living in care homes had higher COVID-19 mortality risk than those living in single houses or apartment buildings.

Why people with dementia go missing

People with dementia are more likely to go missing in areas where road networks are dense, complicated and disordered – according to new research from the University of East Anglia. Researchers studied hundreds of ‘missing person’ police reports for people…

Streetlights contribute less to nighttime light emissions in cities than expected

The combination of smart city lighting and satellite imagery allows measurements of the contribution of street lights to urban lighting for the first time, and gives new hints for how to fight light pollution

The chemistry behind self-driving cars

Self-driving, electric cars have been touted as the next big thing in transportation. While this technology has progressed in recent years, experts caution that automakers will need the chemical industry to help make it a reality. A new article in…

Princeton and Mpala scholars link obesity and disease to dramatic dietary changes

A new study supporting the “mismatch” hypothesis found that obesity, diabetes, and cardiovascular illnesses increased among Turkana people whose diet changed from animal-based to carbohydrate-based.

Food waste: cities can make the difference

Food waste is one of the most important issues of current food systems: Food and Agriculture Organization (FAO) has estimated that more than one third of food is either lost or wasted along the entire food supply chain causing significant…

Light pollution alters predator-prey interactions between cougars and mule deer in western US

A new study provides strong evidence that exposure to light pollution alters predator-prey dynamics between mule deer and cougars across the intermountain West, a rapidly growing region where nighttime skyglow is an increasing environmental disturbance. The University of Michigan-led study…

Unprecedented energy use since 1950 has transformed humanity’s geologic footprint

A new study coordinated by CU Boulder makes clear the extraordinary speed and scale of increases in energy use, economic productivity and global population that have pushed the Earth towards a new geological epoch, known as the Anthropocene. Distinct physical,…

Climate change undermines the safety of buildings and infrastructure in Europe

Buildings and infrastructure also need to adapt to the changing climate. Updating structural design standards is crucial to improving European climate resilience and ensuring the safety of constructions, that are expected to suffer from changes in atmospheric variables and more…

Green pavement markings could make Texas streets safer for cyclists

A University of Texas at Arlington civil engineer is investigating the effectiveness of implementing green pavement markings to denote where bicyclists have dedicated lanes or share the road with motorists. This Texas Department of Transportation (TxDOT)-funded research project will examine…

Shedding light on how urban grime affects chemical reactions in cities

Many city surfaces are coated with a layer of soot, pollutants, metals, organic compounds and other molecules known as “urban grime.” Chemical reactions that occur in this complex milieu can affect air and water quality. Now, researchers reporting in ACS…

Hots Dogs, Chicken Wings and City Living Helped Wetland Wood Storks Thrive

Using the Wood Stork, researchers compared city storks with natural wetland storks to gauge their success in urban environments based on their diet and food opportunities. Results provide evidence of how a wetland species persists and even thrives in an urban environment by switching to human foods like chicken wings and hots dogs when natural marshes are in bad shape. These findings indicate that urban areas can buffer a species from the unpredictability of natural food sources.

The impacts of gentrification on transportation and social support

The historically Black district of Albina in Portland, Oregon, due to racist real estate practices, faced multiple displacement events between 1960 and 1990 with the construction of Interstate 5 through the heart of the neighborhood as well as wholesale destruction of hundreds of homes to make room for the Memorial Coliseum and various other urban renewal projects.

Public health consequences of policing homelessness

Two weeks ago, Colorado State Patrol troopers began clearing out nearly 200 residents from homeless encampments that surround the Colorado Capitol. The enforcement of city ordinances like camping bans, park curfews and obstructions of public passageways is lawful. But the…

Land use changes may increase disease outbreak risks

Global changes in land use are disrupting the balance of wild animal communities in our environment, and species that carry diseases known to infect humans appear to be benefiting, finds a new UCL-led study. The findings, published in Nature ,…

USU launches NSF-funded engineering research center for electrified transportation

LOGAN, UTAH — The National Science Foundation has awarded Utah State University a five-year, $26 million grant, renewable to 10-year, $50.6 million, to develop an international research center dedicated to advancing sustainable, electrified transportation. The center is expected to raise…
