Planet has two parent stars and a sibling, NASA telescope finds
Wed,29 Aug 2012 02:24 PM PDT
Reuters -  CAPE CANAVERAL, Florida (Reuters) - In a dazzling and previously undetected display of orbital dynamics, two planets beyond the solar system have been found circling a pair of stars, scientists using NASA's Kepler space telescope said on Wednesday. Unlike single planets orbiting single stars, the planets in the Kepler-47 system, located about 5,000 light years away in the constellation Cygnus, are flying around a "moving target," San Diego State University astronomer Jerome Orosz said in a paper published in this week's Science magazine. ...

Newly discovered dust-obscured galaxies may be missing link
Wed,29 Aug 2012 01:54 PM PDT
Reuters -  CAPE CANAVERAL, Florida (Reuters) - Scientists on Wednesday unveiled a new species in the cosmic zoo, a super-heated, dust-shrouded object called a "hot DOG," which may represent a missing link in galaxy evolution. A full-sky survey by NASA's wide-field infrared WISE telescope turned up about 1,000 hot, dust-obscured galaxies, or hot DOGs, each of which pump out as much light as 100 trillion sun-like stars. The objects are rare, accounting for about one in 100,000 light sources, and difficult to find since most of their energy is masked by dust. ...

But don't make your kids do it,'" said Nye, best known as host of the educational TV series "Bill Nye the Science Guy. ...

Canada extends search for doomed 1845-46 Arctic expedition
Thu,23 Aug 2012 02:27 PM PDT
Reuters - OTTAWA (Reuters) - The Canadian government said on Thursday it was extending its four-year search for two ships from the 1845-46 Franklin expedition to the Arctic, an ill-fated journey that may have led to cannibalism among the desperate crew. Divers and archeologists have been trying since 2008 to find the British ships HMS Erebus and HMS Terror, which were seeking the fabled Northwest Passage between the Atlantic and the Pacific oceans when they became stuck in ice. Sir John Franklin and his 128-member crew all died and the ships vanished. ... Full Story | Top |

Researchers identify gene that improves rice yields in poor soil
Wed,22 Aug 2012 04:50 PM PDT
Reuters - HONG KONG (Reuters) - A gene that raises rice yields by enhancing root growth and nutrient absorption in low quality soils has been identified in a species of rice in India and successfully introduced into other rice varieties, researchers reported on Thursday. Scientists and rice breeders have known for years that Kasalath rice is unusually efficient at nutrient absorption, but only now have they succeeded in identifying the gene responsible for this important trait. ...

Mars rover Curiosity gears up for Wednesday test drive
Tue,21 Aug 2012 04:14 PM PDT
Reuters -  CAPE CANAVERAL, Florida (Reuters) - NASA's Mars rover Curiosity, dispatched to study if the Red Planet could have hosted life, will take its first test drive on Wednesday. The one-ton, nuclear-powered robotic geologist, which landed inside a Martian crater on August 6, will get instructions for a 30-minute drive, mission manager Michael Watkins told reporters on a conference call Tuesday. Later in the day, Curiosity will drive about 10 feet, turn its wheels, then drive back to its landing site, ending up at a 90-degree angle from where it touched down inside Gale Crater. ...
