Which Came First, The Moth Or The Cactus
Houston TX (SPX) Aug 16, 2007It's not a good idea to put all your eggs in one basket... unless you're a senita moth. Found in the parched Sonoran desert of southern Arizona and northern Mexico, the senita moth depends on a single plant species -- the senita cactus -- both for its food and for a place to lay eggs. The senita cactus is equally dependent upon the moth, the only species that pollinates its flowers. Senita ... more Features Of Replication Suggest Viruses Have Common Themes And Vulnerabilities 
Adison WI (SPX) Aug 16, 2007A study of the reproductive apparatus of a model virus is bolstering the idea that broad classes of viruses - including those that cause important human diseases such as AIDS, SARS and hepatitis C - have features in common that could eventually make them vulnerable to broad-spectrum antiviral agents. In a study published Aug. 14 in the online, open-access journal Public Library of Science ... more Gene Regulation, Not Just Genes, Is What Sets Humans Apart 
Durham NC (SPX) Aug 16, 2007The striking differences between humans and chimps aren't so much in the genes we have, which are 99 percent the same, but in the way those genes are used, according to new research from a Duke University team. It's rather like the same set of notes being played in very different ways. In two major traits that set humans apart from chimps and other primates - those involving brains and diet - ge ... more Unravelling New Complexity In The Genome 
Toronto, Canada (SPX) Aug 16, 2007A major surprise emerging from genome sequencing projects is that humans have a comparable number of protein-coding genes as significantly less complex organisms such as the minute nematode worm Caenorhabditis elegans. Clearly something other than gene count is behind the genetic differences between simpler and more complex life forms. Increased functional and cellular complexity can be ex ... more The Limited Carbon Market Puts 20 Percent Of Tropical Forest At Risk 
Arlington VI (SPX) Aug 16, 2007In an ironic twist, 11 countries that have avoided widespread destruction of their tropical forest are at risk of being left out of an emerging carbon market intended to promote rainforest conservation to combat climate change. A study published Tuesday in the Public Library of Science Biology journal warns that the "high forest cover with low rates of deforestation" (HFLD) nations could become ... more |

Tallahassee FL (SPX) Aug 16, 2007Far from the everyday world occupied by such common elements such as gold and lead lies a little-understood realm inhabited by radioactive, or unstable, elements. Recently, a nuclear physicist from Florida State University collaborated with other scientists from the United States, Japan and England in an experiment that illustrated how the "normal" rules of physics don't apply for some of these ... more Sandia Partners With UOP To Develop Biofuel For Military Jets 
Albuquerque NM (SPX) Aug 16, 2007Researchers at Sandia National Laboratories in Albuquerque, N.M. and Livermore, Calif., are part of a Defense Advanced Research Projects Agency (DARPA) -funded team led by UOP, LLC, a Honeywell company, looking at the production of military Jet Propellant 8 (JP-8) fuel based on the use of renewable biomass oil crop feedstocks, including microalgae. The goal of the 18-month effort, which is ... more Drive-By-Wire And Human Behavior Systems Key To Virginia Tech Urban Challenge Vehicle 
Blacksburg, VA (SPX) Aug 14, 2007Virginia Tech's entry in DARPA's Urban Challenge is moving forward to the qualifying rounds, thanks in part to a custom-designed drive-by-wire control system and unique navigation software that makes the vehicle's driving decisions almost human. VictorTango, a team of Virginia Tech engineering and geography students, is among 36 semi-finalists selected by DARPA ... more DigitalGlobe Announces Launch Date For WorldView-1 
Boulder CO (SPX) Aug 15, 2007Ball Aerospace and Technologies, ITT Corporation and DigitalGlobe, the provider of the world's highest-resolution imagery and geospatial information products, today announced delivery of its WorldView-1 satellite to Vandenberg Air Force Base in California for its scheduled launch on Tuesday, September 18, 2007. WorldView-1 is the first of two new next-generation satellites DigitalGlobe plans to ... more Russian nuclear bombers hold exercises over North Pole 
Moscow (AFP) Aug 14, 2007Russian strategic bombers on Tuesday began five days of exercises over the North Pole, marking the latest in a series of displays of Moscow's military muscle. The nuclear-capable bombers will practice firing cruise missiles, navigation in the polar region and aerial refuelling manoeuvres, the Russian air force said in a statement. The exercises come barely a week after Russian strategic ... more |

Brasilia (AFP) Aug 14, 2007Brazilian President Luiz Inacio Lula de Silva has welcomed figures showing the pace of deforestation in the Amazon has slowed over the past year. "It's important that people be aware that preserving the environment now, doing things in a way that respects the law, is a basic condition for Brazil to win more credibility abroad," Lula said Monday in his weekly radio address. Lula spoke aft ... more North Korea asks UN agency to help with "massive" floods 
Geneva Aug 14, 2007North Korea has asked the UN's food relief agency for help in the wake of "massive" floods, a spokesman for the World Food Programme said Tuesday. North Korean authorities said the floods are worse than those that reportedly left hundreds dead or missing and tens of thousands homeless in central and southern regions last year, WFP spokesman Simon Pluess told AFP. "Pyongyang has made a pr ... more Northern Indonesian volcano spews smoke, heat clouds 
Jakarta (AFP) Aug 14, 2007A volcano on Indonesia's Sulawesi island spewed smoke into the sky and spat heat clouds down its slopes Tuesday, but no evacuation of people in its surrounds was needed, an official said. A column of smoke soared 1,500 metres (yards) above Mount Soputan and clouds of gas shot down its western slope, said Sandi, an official manning the vulcanology observation post on the volcano's slopes. ... more Bangladesh struggles with disease after South Asia floods 
Dhaka (AFP) Aug 14, 2007Bangladesh was struggling to cope Tuesday with a major outbreak of disease as officials said some 100,000 people had been admitted to hospital in August after the worst South Asian flooding in decades. The victims were suffering from diarrhoea and other water-borne diseases, the health department said, with clean water in short supply. At least 100,000 people had been admitted to hospita ... more Global warming boosts crop disease 
Paris (AFP) Aug 14, 2007Global warming will fuel a disease that annually causes hundreds of million dollars in damage to rapeseed plants, used to make canola oil, according to a study released Tuesday. Using weather-based computer models, researchers in Britain predicted that climate change will expand the range and increase the severity of phoma stem canker, which already accounts for 900 million dollars (650 mill ... more
