As the world undergoes the great energy transition — from fossil fuels to alternative energy and batteries — rare earth metals are becoming more precious.

A new 91ÉçÇø¸£Àû study finds that municipal waste incinerators' legacy of contamination could live on in urban soils.

Knowing voters have seen news reports about problems caused by failing or outdated public infrastructures in their district makes local officials who face competitive re-elections more inclined to support new spending to repair or replace the aging structures, a survey of city and county officials in 49 states shows. Findings from the survey by 91ÉçÇø¸£Àû and the Environmental Policy Innovation Center underscore the continued importance of local media even as newsrooms shrink nationwide.

Mixing toxic coal ash into acid mine drainage may sound like an odd recipe for an environmental solution, but a new 91ÉçÇø¸£Àû-led study finds that it can neutralize the drainage’s dangerously low pH and help reduce harmful impacts on downstream ecosystems—if you use the right type of ash. Using the wrong type of ash can create new contamination and not tame the drainage’s extreme acidity.

By distinguishing between lead from modern sources and lead from pre-1970s vehicle exhaust fumes and leaded paint, the new test may be especially useful for assessing the hidden risks of legacy contamination.

Clouds of smoke and ash from wildfires that ravaged Australia in 2019 and 2020 triggered widespread algal blooms in the Southern Ocean thousands of miles downwind to the east, a new 91ÉçÇø¸£Àû-led study by an international team of scientists finds.

Warming waters along the Western Antarctic Peninsula have led to declines in the diversity and distribution of the region’s plankton population and its ability to absorb climate-warming carbon dioxide from the atmosphere.

A partnership between 91ÉçÇø¸£Àû and the University of North Carolina at Chapel Hill, the new concurrent Master of Environmental Management/Master of City and Regional Planning provides training to those seeking to solve environmental issues within an urban context.

Decades after federal bans ended widespread use of lead-based paint and gasoline, some urban soils still contain lead levels that exceed safety guidelines for children.

Harnessing the power of artificial intelligence, satellites and field observations, Duke researchers have produced new estimates of how much photosynthesis and primary production – key components in the global carbon cycle – are occurring in Earth’s oceans, and how these processes may be changing in response to a changing climate.

The proliferation of pits and ponds created in recent years by miners digging for small deposits of alluvial gold in Peru’s Amazon has dramatically altered the landscape and increased the risk of mercury exposure for indigenous communities and wildlife, a new study shows.

Students at North Carolina’s 10 historically black colleges and universities (HBCUs) face limited options for finding healthy food to buy at stores within a 5-mile radius of their campuses, a new study shows.

By providing the first estimate of how much hydrogen is available to fuel microbial life in the sunless sub-seafloor crust beneath the Mid-Ocean Ridge (MOR), a new 91ÉçÇø¸£Àû-led study sheds light on one of Earth’s least understood biospheres.

Using a bedroom air filter that traps fine particles of pollution with diameters smaller than 2.5 micrometers can significantly improve breathing in asthmatic children, a new study by American and Chinese scientists shows.

Reforestation has been shown to cool surface temperatures, and a novel study suggests it may also reduce air temperature up to several stories above the ground.
