SAVANNAH, Ga. (AP) — Rare sea turtles are smashing nesting records this summer on beaches in the Southeast, with scientists crediting the egg-laying boom to conservation measures that began more than 30 years ago. Giant loggerhead sea turtles weighing up to 300 pounds (136 kilograms) crawl ashore...

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...

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.
