Decades after a uranium mine is shuttered, the radioactive element can still persist in groundwater at the site, despite cleanup efforts.

A recent study led by scientists at the Department of Energy’s SLAC National Accelerator Laboratory helps describe how the contaminant cycles through the environment at former uranium mining sites and why it can be difficult to remove. Contrary to assumptions that have been used for modeling uranium behavior, researchers found the contaminant binds to organic matter in sediments. The findings provide more accurate information for monitoring and remediation at the sites.

The results were published in the Proceedings of the National Academy of Sciences.

In 2014, researchers at SLAC’s Stanford Synchrotron Radiation Lightsource (SSRL) began collaborating with the DOE Office of Legacy Management, which handles contaminated sites associated with the legacy of DOE’s nuclear energy and weapons production activities. Through projects associated with the Uranium Mill Tailings Radiation Control Act, the DOE remediated 22 sites in Colorado, Wyoming and New Mexico where uranium had been extracted and processed during the 1940s to 1970s.

Nearly a decade after being logged, vegetation in forested areas severely burned by California's Cone Fire in 2002 was relatively similar to areas untouched by logging equipment. The findings of a U.S. Forest Service study shed light on how vegetation responds to severe wildfire and whether further disturbances from logging affect regrowth.

A report published in the journal Biological Conservation finds that recent increases in human pressure and forest loss are causing the degradation of over 100 Natural World Heritage Sites (NWHS) globally.

China leads the world in greenhouse gas emissions. Its biggest cities are shrouded in smog. And the country’s population is 1.4 billion people and growing. At least to the rest of the world, China isn’t known as a leader in environmental mindfulness.

Forest-dwelling bird species are disappearing from some of South Africa's indigenous forests, with forest birds in the Eastern Cape being the most affected.

World-first research on the Great Barrier Reef has shown how ‘weed-like’ algae will kill vital coral because of increased carbon dioxide concentrations in the atmosphere.

A group of scientists is recommending giving the world’s nature reserves a makeover to defend not only flora and fauna, but people, too.

Scientists in this week’s Proceedings of the National Academy of Sciences argue that the world’s protected areas such as nature reserves, traditionally havens for endangered animals and plants, can be made better if they ratchet up benefits that directly help people. The world’s nature reserves not only defend nature for nature’s sake, but also can curb erosion, prevent sandstorms, retain water and prevent flooding and sequester carbon. The authors include more of a place for people – judiciously.

LSU scientists will present new research at the 2017 Gulf of Mexico Oil Spill and Ecosystem Science Conference in New Orleans next week. These experts will be among hundreds of oil spill-related researchers from academia, state and federal agencies, non-governmental organizations and industry, who will share the latest oil spill and ecosystem scientific discoveries, innovations, technologies and policies on Feb. 6-9.

A long-standing mystery among marine biologists is why otherwise healthy whales, dolphins, and porpoises — collectively known as cetaceans — end up getting stranded along coastal areas worldwide. Could severe solar storms, which affect Earth’s magnetic fields, be confusing their internal compasses and causing them to lose their way?

Genetically modified organisms for pest control could end up as contaminants in agricultural products throughout the globe.
