Sometimes finding a skeleton in a closet can be a good thing — if you’re a paleontologist. Meet Pelagornis sandersi, a giant bird with a wingspan 21 feet across — so wide that it could have been the size of a (very) small plane.
Discoveries by NASA’s Curiosity rover are giving scientists a picture of Mars that looks increasingly complex, with small bits of water spread around the surface and an interior that could have been more geologically mature than experts had thought.
LOS ANGELES - A pair of fossil dinosaur skeletons dubbed the Montana Dueling Dinosaurs are headed for auction rather than straight to a museum.
LOS ANGELES - With the help of a little alcohol, scientists have discovered supposedly impossible chemical reactions in the cold reaches of space. Organic molecules like methanol are being created and destroyed in clouds of interstellar gas, thanks to a spooky process called quantum tunneling.
Archaeologists have found a hidden tomb of the Wari, a monument from an early civilization that predated the Inca, nestled in a site 175 miles north of Lima, Peru.
Before they set foot in kindergarten, some children are armed to the teeth with new words, while others come bearing far smaller verbal arsenals. What factors at home affect how wordy children's brains are in their early years? A new study in Proceedings of the National Academy of Sciences s…
Astronomers have discovered a strangely tiny galaxy in the Milky Way's neighborhood - one with less than 1,000 stars held together by the smallest dark-matter halo ever observed.
LOS ANGELES - The harlequin ladybird was once a stalwart ally of greenhouse growers around the world. Native to Japan, Korea and other parts of eastern Asia, the bright red ladybugs were prized for their aphid-eating abilities - until they caused serious declines in other ladybug populations.
LOS ANGELES - A crew of Mongolian gerbils may have gone where no Mongolian gerbil has gone before, but they did not come back alive.
LOS ANGELES - Bedbugs have re-emerged as an urban blight in the past several years, forcing people out of homes, resisting chemical pesticides and evading other removal tactics. But researchers are building bug-catchers inspired by an age-old folk remedy to this "ancient scourge": kidney bea…
LOS ANGELES - A treatment that removes heavy metals from the body has long been touted as an alternative therapy to combat hardening arteries. Now a 10-year, $31 million clinical trial has found that chelation therapy does help heart attack patients slightly reduce their risk of serious hear…
It was welcome news to Earthlings: The Voyager 1 spacecraft had seemingly crossed a momentous threshold and become the first man-made object to enter interstellar space.
The universe has hidden its age well. The European Space Agency's Planck space telescope has scanned the skies for the Big Bang's fingerprint and discovered that the universe is about 100 million years older than thought, and that there's more normal and dark matter filling the cosmos.
LOS ANGELES - Years of trying to do too many things with too little money have put NASA at risk of ceding its leadership in space exploration to other nations, according to a new report that calls on the space agency to make some wrenching decisions about its long-term strategy and future scope.

LOS ANGELES - Doctors should give underage teenagers prescriptions for emergency contraceptives such as Plan B before they start having sex instead of waiting until a young patient's "Plan A" goes awry, the American Academy of Pediatrics says in a new policy statement.
LOS ANGELES — Scientists have spent years hunting for Earth-like planets orbiting stars elsewhere in the galaxy. Now they have found one that’s a relative stone’s-throw away.
LOS ANGELES — The smallest planet in the solar system keeps serving up big surprises. Scientists working on the Messenger mission to Mercury have found that the planet has unexpected inner layers and craters with tilted bottoms, and it may have been geologically active far later into its lif…
