To save Appalachia’s endangered mussels, scientists hatched a bold plan

Biologists have just begun to learn whether their bold plan worked to save the golden riffleshell, a freshwater mussel teetering on the brink of extinction.

Health & Medicine

Many U.S. neighborhoods with the worst air 40 years ago remain the most polluted

Air pollution has declined in the United States, but marginalized communities are still disproportionately affected despite the improvement.
