Los Angeles sued the Justice Department on Tuesday over the Trump administration's threat to cut millions in federal funding for so-called sanctuary cities, which limit their cooperation with federal authorities on immigration enforcement.

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 developer behind the Dakota Access Pipeline, which for months drew thousands of protesters, has sued Greenpeace and several other environmental groups for their role in delaying the pipeline's construction.

The British publisher of an academic journal has reversed a decision to take down hundreds of articles from its Chinese website.

In a statement released Monday, Cambridge University Press said it's reposting the more than 300 articles to "The China Quarterly."

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.

"Overall, women may increase their risk in general by about 33 percent by using talc in their hygiene," Cramer says.

This week's Trump presidency Internet sideshow (see also: Melania appearing to bat Trump's hand away, the president's aggressive handshakes, the frenzy over Kellyanne Conway's inauguration outfit) came in the form of a couture-heavy Instagram post from Louise Linton, a Scottish-born actr

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.
