Climate change could lead to conflict, instability: UN report
Nusa Dua, Indonesia (AFP) Dec 10, 2007Global warming could lead to internal conflict, regional unrest and war, with North Africa, the Sahel and South Asia among the hotspots, a report issued at a global climate change forum said Monday. The warning by the UN Environment Programme (UNEP) came just hours ahead of ceremonies in Oslo to award the 2007 Nobel Peace Prize to US climate campaigner Al Gore and the UN's top scientific pan ... more At least 11 dead as ice storm sweeps central US 
Washington (AFP) Dec 10, 2007At least 11 people have been killed as an ice storm swept the United States Monday, turning roads into slippery death-traps and leaving hundreds of thousands without power, officials said. "According to the Oklahoma Department of Emergency Management, there have been 11 confirmed fatalities in Oklahoma alone, due to weather-related traffic accidents," said Dave Nadler, a meteorologist at the ... more Don't push us too hard, China tells US ahead of trade dialogue 
Beijing (AFP) Dec 10, 2007A week of senior Sino-US economic exchanges kicked off on Monday with China warning the United States not to push too hard on sensitive issues, amid long-standing tensions over the Chinese currency. China also said it would triple the quota for foreign stock investment, in a gesture analysts said was meant to create the appearance ahead of the Strategic Economic Dialogue that it was moving o ... more White House races a dogfight, three weeks out 
Washington (AFP) Dec 10, 2007Republican and Democratic White House races are turning into cliffhangers, as candidates launch a three-week home stretch campaign blitz ahead of first presidential nominating contests. Tightening opinion polls lent a critical edge to a looming Republican debate Wednesday and a Democratic clash Thursday, both in Iowa -- the last head-to-head clash of candidates in the state before its Januar ... more Nitrous Oxide From Ocean Microbes 
London, UK (SPX) Dec 11, 2007A large amount of the greenhouse gas nitrous oxide is produced by bacteria in the oxygen poor parts of the ocean using nitrites, Dr Mark Trimmer told journalists at a Science Media Centre press briefing. Dr Trimmer looked at nitrous oxide production in the Arabian Sea, which accounts for up to 18% of global ocean emissions. He found that the gas is primarily produced by bacteria trying to make n ... more |

London, UK (SPX) Dec 11, 2007Carbon dioxide increasing in the atmosphere may affect the microbial life in the sea, which could have an impact on a major food source, warned Dr Ian Joint at a Science Media Centre press briefing today. Dr Joint is sequencing the DNA of different ocean bacteria to find out how they will respond to an increase in carbon dioxide. "So far from one experiment we have sequenced 300 million bases of ... more West Antarctica To Be Covered With Network To Keep Watch Through The Dark Polar Night 
Columbus OH (SPX) Dec 11, 2007In a mission of unprecedented scale, scientists are about to cover West Antarctica with a network of sensors to monitor the interactions between the ice and the earth below -- 24 hours a day, 365 days a year. The National Science Foundation (NSF) just awarded the collaboration, called POLENET, $4.5 million to plant global positioning system (GPS) trackers and seismic sensors on the bedrock that ... more Waterborne Carbon Increases Threat Of Environmental Mercury 
Madison WI (SPX) Dec 11, 2007Mercury is a potent neurotoxin and a worrisome environmental contaminant, but the severity of its threat appears to depend on what else is in the water. Researchers at the University of Wisconsin-Madison have found that the presence of dissolved organic material increases the biological risk of aqueous mercury and may even serve as an environmental mercury source. Mercury is present throug ... more Threatened Birds May Be Rarer Than Geographic Range Maps Suggest 
San Diego CA (SPX) Dec 11, 2007Geographic range maps that allow conservationists to estimate the distribution of birds may vastly overestimate the actual population size of threatened species and those with specific habitats, according to a study published online this week in the journal Conservation Biology. "Our study found that species ranges in general tend to get overestimated, but that this trend is particularly p ... more Methane From Microbes: A Fuel For The Future 
York, UK (SPX) Dec 11, 2007Microbes could provide a clean, renewable energy source and use up carbon dioxide in the process, suggested Dr James Chong at a Science Media Centre press briefing today. "Methanogens are microbes called archaea that are similar to bacteria. They are responsible for the vast majority of methane produced on earth by living things" says Dr Chong from York University. "They use carbon dioxide ... more |

The Dalles, Ore. (UPI) Dec 10, 2007 The solution to Africa's poverty rates lies within the soil that stretches across the vast land mass, a group of government leaders and development experts say. Agriculture holds the key to economic development for the continent, these experts say, and strategies for jump-starting the industry will take center stage at an upcoming congress scheduled for Uganda next September. Organized ... more Climate survey pooh-poohs biofuels 
Nusa Dua, Indonesia (AFP) Dec 10, 2007Biofuels may be rising in popularity worldwide but policymakers largely reject them as a way to fight global warming, a survey said Monday. A poll of 1,000 climate change "decision makers" from 105 countries, including government and industry officials, listed solar energy as the technology with the top potential to cut carbon emissions. Wind farms also ranked highly in the World Bank-su ... more Light Is Shed On New Fibre's Potential To Change Technology 
Bath, UK (SPX) Dec 11, 2007Photonic crystal fibre's ability to create broad spectra of light, which will be the basis for important developments in technology, has been explained for the first time in an article in the leading science journal Nature-Photonics. The fibre can change a pulse of light with a narrow range of wavelengths into a spectrum hundreds of times broader and ranging from visible light to the infra-red. ... more Hinode: New Insights On The Origin Of Solar Wind 
Paris, France (ESA) Dec 10, 2007Spectacular images and data from the Hinode mission have shed new light on the Sun's magnetic field and the origins of solar wind, which can disrupt power grids, satellites and communications on Earth. The results are published in the 7 December issue of the journal Science. Data from Hinode, a Japanese (JAXA) mission with ESA participation, shows that magnetic waves play a critical role in driv ... more Swedish Space Takes Major Role In Galileo Satellite Navigation Project 
Solna, Sweden (SPX) Dec 07, 2007SSC has a number of contracts linked to the Galileo system. The system's first ground control station is owned by SSC and located at the company's facility Esrange Space Center. Around 25 MEUR will be invested in the Galileo antenna site, which will be a key installation in the Galileo system. The antenna building has been erected in preparation for the delivery of the 13.6 meter antenna - the l ... more
