Normally the male and females stay as they are, feeding together and occasionally mating. But if a predator happens to snatch up the lead male, the dominant female in the group will take up rank _ by becoming a male. (Kevin Bryant via AP)

NEW YORK (AP) — If in the beginning there was male and female, fish seem to have forgotten the memo. For nearly 500 fish species, including the clownfish in "Finding Nemo," the great divide between sexes is more like a murky line: If circumstances call for it, the fish can swap their sex, with...

Water flows through Conowingo Dam, a hydroelectric dam spanning the lower Susquehanna River near Conowingo, Md., on Thursday, May 16, 2019. Officials once counted on the dam to block large amounts of sediment in the Susquehanna from reaching Chesapeake Bay, the nation's largest estuary, but the reservoir behind the dam has filled with sediment far sooner than expected.

CONOWINGO, Md. (AP) — When the Conowingo Dam opened to fanfare nearly a century ago, the massive wall of concrete and steel began its job of harnessing water power in northern Maryland. It also quietly provided a side benefit: trapping sediment and silt before it could flow miles downstream and...

WASHINGTON (AP) — The most effective way to fight global warming is to plant lots of trees, a study says. A trillion of them, maybe more. And there's enough room, Swiss scientists say. Even with existing cities and farmland, there's enough space for new trees to cover 3.5 million square miles (9...

This artist's rendering made available by NASA shows multiple views of the Dragonfly dual-quadcopter lander that would take advantage of the atmosphere on Saturn's moon Titan to explore multiple locations, some hundreds of miles apart. On Thursday, June 2u7, 2019, NASA announced it would send the drone to the jovian planet's largest moon. Scientists have long considered Titan an attractive place to study whether it would be capable of supporting microbial life. (NASA via AP)

NASA is sending a drone to explore Saturn's largest moon. The space agency said Thursday the Dragonfly mission will fly over Titan, exploring different locations on the icy moon to study whether it can support microbial life. The mission, part of NASA's competitive New Frontiers program, beat out...
