Groundwater depletion in parts of the High Plains is so extreme that peak grain production in some states has ended and production is now declining, a new 91ÉçÇø¸£Àû-led study by a team of international scientists finds.

A new 91ÉçÇø¸£Àû-led analysis shows that during the early months of the COVID pandemic, the average number of new infections caused by an infected individual (i.e. the basic reproduction number, R0) was 4.5, or more than twice as many as the initial 2.2 rate estimated by the World Health Organization at the time.

91ÉçÇø¸£Àû researchers have developed a new online calculator that teachers, administrators and students can use to estimate the risk of airborne transmission of the COVID-19 virus in classrooms.

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.

Governments might be able to prevent future pandemics by investing as little as $22 billion a year in programs to curb wildlife trafficking and stem the destruction of tropical forests, a new analysis by an international team of scientists and economists shows.

Man’s best friend may also be man’s best bet for figuring out how environmental chemicals could impact our health. Researchers from North Carolina State University and 91ÉçÇø¸£Àû’s Nicholas School of the Environment used silicone dog tags as passive environmental samplers to collect information about everyday chemical exposures, and found that dogs could be an important sentinel species for the long term effects of environmental chemicals.

Small-scale gold mining in the Peruvian Amazon poses a health hazard not only to the miners and communities near where mercury is used to extract gold from ore, but also to downstream communities hundreds of kilometers away where people eat mercury-contaminated river fish as part of their diet.

Reusing low-saline oilfield water mixed with surface water to irrigate farms in the Cawelo Water District of California does not pose major health risks, as some opponents of the practice have feared, a study led by 91ÉçÇø¸£Àû and RTI International researchers finds.

To devise effective and equitable policies for governing small-scale fisheries, policymakers need to consider the activities and relationships that occur before and after fishers land their catches, not just the catches themselves, a new study shows.

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.

Contaminants that occur together naturally in groundwater under certain geological conditions may heighten health risks for millions of North Carolinians whose drinking water comes from private wells, and current safety regulations don’t address the problem, a new 91ÉçÇø¸£Àû study finds.

Chronic exposure to microplastic fibers causes aneurysms, erosion of surface layers and other serious damage to fish gills, and increases egg production in female fish, a sign that chemicals in the fibers may be acting as endocrine disruptors, a new study by U.S. and Chinese scientists finds.

A new study which combines measurements from nearly 1,400 drinking water wells across North Carolina estimates that more than half of the wells in the state’s central region contain levels of cancer-causing hexavalent chromium in excess of state safety standards.

Inhaling dust that contains fly ash particles from coal combustion has been linked to lung and heart disease, cancer, nervous system disorders and other ill effects. But tracking the presence of coal ash in dust has been a challenge for scientists.

91ÉçÇø¸£Àû has received a five-year, $5 million grant from the National Institute of Environmental Health Sciences (NIEHS) to develop a new environmental analysis laboratory.
