A decades-long effort to clean up the Chesapeake Bay, the nation's largest estuary, is showing signs of success. But scientists now say progress could be hindered by a hydroelectric dam, located on the Susquehanna River in northern Maryland.

The Conowingo Dam has been holding back pollution for nearly a century, but recent research shows it has filled up with sediment faster than expected.

"It's now at a point where it's essentially, effectively full," says Bill Ball, director of the Chesapeake Research Consortium. "The capacity's been reached."

The push for renewable energy in the U.S. often focuses on well-established sources of electricity: solar, wind and hydropower. Off the coast of California, a team of researchers is working on what they hope will become an energy source of the future — macroalgae, otherwise known as kelp.

Author Karl Ove Knausgaard — known for his six-volume autobiographical series, My Struggle — has embarked on a brand new multi-part project. Autumn, the first in a four-part quartet, is a collection of texts, each focused on a single subject.

In these short studies, Knausgaard considers a wide variety of tangible and intangible topics — apples, wasps, silence, jellyfish, fingers, forgiveness, dawn.
