Organisms floating in currents beneath a river’s surface are exposed to far less sunlight than scientists previously believed, and the light that does reach them is mostly sporadic and short-lived, a new 91��������-led study shows.

Coal ash solids found in sediments collected from Sutton Lake in 2015 and 2018 suggest the eastern North Carolina lake has been contaminated by multiple coal ash spills, most of them apparently unmonitored and unreported until now.

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.

91�������� has acquired rights to create a 10,000-acre “carbon farm.” When fully operational, the farm could potentially store enough carbon to help Duke meet its goal of achieving carbon neutrality by 2024.
