NASA ponders space station power problem
October 29, 2007 07:49 AM - Irene Klotz -Reuters

Two spacewalking astronauts on Sunday found metal shavings inside a huge gear that spins a pair of the International Space Station's solar wing panels, raising concerns about power supplies and the long-term health of the orbital outpost. The inspection of one of the $100 billion space station's two solar panel rotary joints was added to the second of five spacewalks planned during the space shuttle Discovery's ongoing construction and servicing mission to the station.

 

 

 

 

Discovery may help treat drug addicts

SANTIAGO (Reuters) - Chilean scientists have made a discovery in the brains of rats that they say may help treat drug addiction and ease the side effects of some medications.

Researchers at the Pontifical Catholic University in Santiago say they identified a region of the brain, the insular cortex, that plays an important role in drug craving.

Tests on amphetamine-addicted laboratory rats showed that when the insular cortex was deactivated by injecting a drug that halted brain cell activity, the rats showed no signs of addiction.

HONG KONG (Reuters) - It's autumn in Hong Kong but the island's beaches are still crowded with sun worshippers desperate to catch the last rays of sunshine before winter.

"I love the bronze color," says sunbather Richard Tong.

A growing trend in East Asia to soak up the sun either on beaches or in tanning salons is worrying dermatologists in the region who say they are seeing a rise in skin cancer, which is caused by cumulative over-exposure to the sun.

U.S. Air Force Turns to Alternative Fuel, Slashing CO2
October 27, 2007 11:44 AM - Jim Wolf, Reuters

WASHINGTON (Reuters) - The world's most powerful air force is seeking to wean itself from foreign oil and nearly zero out its carbon dioxide output as part of a sweeping alternative energy drive, a senior Pentagon official said on Friday.

By early 2011, the U.S. Air Force aims to make sure its entire fleet of bombers, fighters, transports and other aircraft can use a domestically produced 50-50 blend of synthetic and petroleum-based fuel.

William Anderson, an assistant Air Force secretary, said the goal was to reduce energy demand, look for cleaner power sources and to reuse captured carbon commercially, for instance to enhance the growth of biofuels or improve oil well production.

"We can get ourselves very close to a zero carbon footprint," said Anderson ahead of talks on the issue with counterparts in Britain and France next month.

"Not today. Not tomorrow. But maybe a decade or so down the road," he told a briefing at the State Department's Foreign Press Center.

TOKYO (Reuters) - Toyota Motor Corp will slash the price and size of its hybrid system by around half for the next-generation Prius model, and use a nickel-metal hydride battery instead of lithium-ion, a top executive said.

"When we went from the first-generation Prius to the second-generation, we did the same thing," Executive Vice President Kazuo Okamoto, in charge of Toyota's research and development, told reporters in Tokyo.

Toyota, the world's biggest automaker, has not publicly disclosed a timeframe for the introduction of the third-generation Prius model. Some media reports have speculated the planned late-2008 launch would be delayed because of concerns over the safety of lithium-ion batteries.

Agricultural soil erosion not adding to global warming
October 25, 2007 06:45 PM - University of California, Davis

Davis, California - Agricultural soil erosion is not a source of carbon dioxide to the atmosphere, according to research published online today (October 25) in the journal Science. The study was carried out by an international team of researchers from UC Davis, the Catholic University of Leuven in Belgium, and the University of Exeter in the U.K.  Carbon emissions are of great concern worldwide because they, and other greenhouse gases, trap heat in the Earth's atmosphere and are a major cause of global climate change.

October 25, 2007 01:33 PM -

PITTSBURGH - Pittsburgh Paints, a global paint product manufacturer, today announced a major greening of it's product lines. The 2008-2009 season will see the introduction of a line of no VOC paints and a new color palette called "EcoEcho".

Part of the new line includes a thematic approach to colors called the 'Voice of Color' program. This approach to colors is based on the idea that every color has an emotional association and that individuals are drawn to different colors for reason inherently tied to their unique personalities. It's an ancient design notion, applied on a grand scale for the first time by a major paint manufacturer.
