Sixteen years after the restoration of Upper Sandy Creek began, hundreds of species, some rare, now call the once-heavily eroded and degraded stream home, and nitrogen pollution flowing off Duke’s campus into downstream waters has been slashed by 75%.

When it comes to storing carbon during prolonged periods of drought and heat, wooded peatlands at low-latitudes have a three- to five-fold advantage over other peatlands. An ancient class of slow-growing fungi is the reason why.

91ÉçÇø¸£Àû researchers have found high levels of toxic heavy metals in coal ash from the Dominican Republic’s largest coal-fired power plant.

Massive power outages in Texas brought on by a historic freeze could be avoided in the future if the state no longer isolates its power grid from other states, among other steps, according to 91ÉçÇø¸£Àû experts.

Salt marshes, seagrass meadows and other coastal ecosystems are in rapid decline around the world. Restoring them is expensive and often unsuccessful. But an international team of researchers has discovered a way to sharply increase the odds of success by using biodegradable mats.

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.

High-intensity fires can destroy peat bogs and cause them to emit huge amounts of their stored carbon into the atmosphere as greenhouse gases, but a new 91ÉçÇø¸£Àû study finds low-severity fires spark the opposite outcome.

A new $2.44 million grant from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) will support a 91ÉçÇø¸£Àû-led initiative to help utilities and wholesale electricity markets improve their efficiency and reliability while reducing emissions and costs, at a time of needed transformations to tackle climate change.

The 91ÉçÇø¸£Àû Wetland Center is marking its 30th anniversary this year by kicking off the largest expansion of research, teaching and outreach programs in its history.

Tanker traffic through the Strait of Hormuz can decline for up to two years after a piracy attack, a new 91ÉçÇø¸£Àû study finds, but the adverse effects of the slowdown are far greater on some Persian Gulf countries than others.

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.

The ongoing transition from coal to natural gas and renewables in the U.S. electricity sector is dramatically reducing the industry’s water use, a new 91ÉçÇø¸£Àû study finds.

With the Environmental Protection Agency (EPA) poised to loosen coal ash rules for dry onsite storage and large fill projects, a new study from 91ÉçÇø¸£Àû finds that leaving those contaminants exposed may significantly heighten the risk of toxic contamination to nearby soil and waterways.

Allowing coal ash to be spread on soil or stored in unlined pits and landfills will raise the risk that several toxic elements, including carcinogenic hexavalent chromium, could leach out of the coal ash and contaminate nearby water supplies across the U.S., according to preliminary findings from a new 91ÉçÇø¸£Àû study.

A new study finds that shoreline erosion rates can double following the death of plants on wetland edges, such as these marshes in Louisiana’s Barataria Bay that were heavily oiled by 2010’s Deepwater Horizon oil spill.
