CAPE CANAVERAL, Fla. (AP) — Neptune's newest and tiniest moon is probably an ancient piece of a much larger moon orbiting unusually close. In the journal Nature on Wednesday, California astronomers shine a light on the 21-mile-diameter (34-kilometer-diameter) moon Hippocamp, named after the...

ALBUQUERQUE, N.M. (AP) — Harvard scholar Henry Louis Gates, Jr., hopes this season of his popular PBS series "Finding Your Roots" helps a divided U.S. see how all Americans have unique family links and how those family histories tell the story of the country. Now in its fifth season, the series...

PHOENIX (AP) — Dolphinaris Arizona opened in the metro Phoenix desert two years ago as marine parks elsewhere were scaling back exhibits amid criticism of the treatment of animals. Animal rights advocates took aim at Dolphinaris as well, saying that putting dolphins in pools on tribal land in the...

In this undated photo provided by researcher Alex Jordan in February 2019, a cleaner wrasse interacts with its reflection in a mirror placed on the outside of the aquarium glass. The mirror itself cannot be seen in this photo because the aquarium glass itself becomes reflective at the viewing angle of the camera, but the fish sees the aquarium glass as transparent because of its direct viewing angle. In a report released on Thursday, Feb 7, 2019, scientists say that 10 fish they studied can pass a standard test of recognizing themselves in a mirror _ and that is posing a key question for experts in animal mental prowess. Does this 50-year-old test for self-awareness in animals really show that ability? (Alex Jordan via AP)

NEW YORK (AP) — Scientists report that a fish can pass a standard test of recognizing itself in a mirror — and they raise a question about what that means. Does this decades-old test, designed to show self-awareness in animals, really do that? Since the mirror test was introduced in 1970,...

NEW YORK (AP) — Scientists report that a fish can pass a standard test of recognizing itself in a mirror, but they are questioning just what that means. The test was designed to show self-awareness in animals, but a new study says that may not be so. Few animals can pass the test, which involves...
