Stuck bolt on space station stymies spacewalkers
Thu,30 Aug 2012 04:34 PM PDT
Reuters -  CAPE CANAVERAL, Florida (Reuters) - NASA on Thursday halted attempts to replace a power distributor on the International Space Station after spacewalking astronauts were repeatedly stymied by a jammed bolt, officials said. NASA astronaut Sunita Williams and Japan's Akihiko Hoshide, both station flight engineers, had planned to spend 6.5 hours outside the orbital outpost to work on its power system and install electrical cables for a new Russian module expected to arrive next year. ...

Rocket blasts off, puts NASA radiation belt probes in orbit
Thu,30 Aug 2012 04:42 AM PDT
Reuters -  CAPE CANAVERAL, Fla., August 30 - An unmanned Atlas 5 rocket lifted off on Thursday from Cape Canaveral Air Force Station in Florida, placing a pair of heavily shielded NASA science satellites into position to study Earth's radiation belts. The 190-foot (58-meter) tall rocket, built by United Launch Alliance, blasted off at 4:05 a.m. EDT (0805 GMT), soaring out over the Atlantic Ocean toward an orbit as far as 19,042 miles above the planet's surface. ...

"Little flash" as bionic eye brings amazed woman some sight
Wed,29 Aug 2012 11:41 PM PDT
Reuters -  SYDNEY (Reuters) - A bionic eye has given an Australian woman partial sight and researchers say it is an important step towards eventually helping visually impaired people get around independently. Dianne Ashworth, who has severe vision loss due to the inherited condition retinitis pigmentosa, was fitted with a prototype bionic eye in May at the Royal Victorian Eye and Ear Hospital. It was switched on a month later. "All of a sudden I could see a little flash ... it was amazing," she said in a statement. ...

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. ...
