Satellites Play Vital Role In Understanding The Carbon Cycle
Montreux, Switzerland (SPX) Apr 26, 2007The global carbon cycle plays a vital role in climate change and is of intense importance to policy makers, but significant knowledge gaps remain in our understanding of it. Several scientists at the Envisat Symposium this week have highlighted research projects using ESA satellites to understand better this complex process. The total number of carbon atoms on Earth is fixed - they are exc ... more At Least Nine Dead After Tornado On Southern Texas Border 
Washington (AFP) April 25, 2007A tornado ripped across the US-Mexico border, killing at least nine people and injuring dozens more, local authorities and media said on Wednesday. Six people were killed in the small Texas town of Eagle Pass, officials said. Three others were killed in Mexico a few miles (kilometers) away, television station KDFW in Dallas reported. The tornado struck Eagle Pass, at about 6:00 pm (2200 GM ... more Liverpool Scientists Work To Improve Water Quality In Ghana 
Liverpool UK (SPX) Apr 26, 2007Ghana's large and growing population relies on wetlands for food and water and so experts at the University's Institute for Sustainable Water, Integrated Management and Ecosystem Research (SWIMMER) have launched a research and training project near Accra, in Southern Ghana, to prevent continued environmental decline through pollution and over-use of river based resources. In recent years G ... more Global Warming And Antarctic Ice Is Focus Of Multinational Workshop 
Tallahassee FL (SPX) Apr 26, 2007As the national repository for geological material from the Southern Ocean, the Antarctic Marine Geology Research Facility at Florida State University houses the premier collection of Antarctic sediment cores -- and a hot new acquisition will offer an international team of scientists meeting there May 1-4 its best look yet at the impact of global warming on oceans worldwide. The remarkable ... more Experts Warn On Gambia AIDS Cure 
West Palm Beach FL (UPI) April 24, 2007Officials of the International AIDS Society Tuesday urged caution over reports that treatment derived from natural herbs in Gambia can cure AIDS. The purported cure is administered directly to the patients by the president of Gambia, an African nation with a population of 1.6 million. "It is premature and unethical to label this product a cure if it has not been thoroughly tested and prove ... more |

China Delays Release Of Climate Change Report
Beijing (AFP) April 24, 2007China has delayed releasing a long-awaited plan for dealing with climate change, an official said Tuesday, amid reports that various levels of government remain divided over the issue. "The release of the National Plan on Climate Change has been postponed, it was supposed to be released... today," Xu Huaqing, director of the National Development and Reform Commission's energy research inst ... read more Satellites Offer Sunny Outlook On Understanding Polar Climate With Help Of Cloudy Skies 
Greenbelt MD (SPX) Apr 25, 2007Far beyond signaling the day's weather, clouds play a key role in regulating and understanding climate. A team of researchers recently completed a project to confirm what NASA satellites are telling us about how changes in clouds can affect climate in the coldest regions on Earth. Clouds and their traits - their temperature, depth, size and shape of their droplets - play a significant role ... more Mosquito Genes Explain Response To Climate Change 
Eugene OR (SPX) Apr 25, 2007University of Oregon researchers studying mosquitoes have produced the first chromosomal map that shows regions of chromosomes that activate - and are apparently evolving - in animals in response to climate change. The map will allow researchers to narrow their focus to identify specific genes that control the seasonal development of animals. Such information will help predict which animal ... more Researcher Finds Negative Effects Of Colonization On Slash-And-Burn Farming In Borneo 
Columbia MO (SPX) Apr 25, 2007A researcher at the University of Missouri-Columbia has examined the slash-and-burn farming method traditionally used by the Iban, a widespread indigenous population that lives in northwestern Borneo in Southeast Asia. Researchers have long argued about the environmental effects of this type of agriculture. Reed L. Wadley, assistant professor of anthropology in the College of Arts and Scie ... more Sea Snails Break The Law 
Washington DC (SPX) Apr 25, 2007Lizards gave rise to legless snakes. Cave fishes don't have eyeballs. In evolution, complicated structures often get lost. Dollo's Law states that complicated structures can't be re-evolved because the genes that code for them were lost or have mutated. A group of sea snails breaks Dollo's law, Rachel Collin, Staff Scientist at the Smithsonian Tropical Research Institute and colleagues from two ... more Ultrasound Upgrade Produces Images That Work Like 3-D Movies 
Durham NC (SPX) Apr 25, 2007Parents-to-be might soon don 3-D glasses in the ultrasound lab to see their developing fetuses in the womb "in living 3-D, just like at the IMAX movies," according to researchers at Duke University's Pratt School of Engineering. The same Duke team that first developed real-time, three-dimensional ultrasound imaging says it has now modified the commercial version of the scanner to produce a ... more |

First Rainforest Unearthed
Bristol UK (SPX) Apr 24, 2007A spectacular fossilised forest has transformed our understanding of the ecology of the Earth's first rainforests. It is 300 million years old. The forest is composed of a bizarre mixture of extinct plants: abundant club mosses, more than 40 metres high, towering over a sub-canopy of tree ferns, intermixed with shrubs and tree-sized horsetails. Nowhere elsewhere on the planet is it possibl ... read more In An Indonesian Bay Fish Tumours And Controversy 
Buyat Bay, Indonesia (AFP) April 23, 2007Junaidi, a 20-year-old fisherman, proudly shows off his catch as children play nearby in the turquoise waters of Indonesia's Buyat Bay. "I would not move anywhere else, where else would you easily get this much fish?" asked Junaidi, pointing to a tub full of fish caught in the bay. Like many in this tranquil and remote coastal community, Junaidi rejects claims that the bay on the northern ... more Junk DNA Now Looks Like Powerful Regulator 
Stanford, CA (SPX) Apr 24, 2007Large swaths of garbled human DNA once dismissed as junk appear to contain some valuable sections, according to a new study by researchers at the Stanford University School of Medicine and the University of California-Santa Cruz. The scientists propose that this redeemed DNA plays a role in controlling when genes turn on and off. Gill Bejerano, PhD, assistant professor of developmental bio ... more How To Manage Forests In Hurricane Impact Zones 
Asheville NC (SPX) Apr 24, 2007Forest Service researchers have developed an adaptive strategy to help natural resource managers in the southeastern United States both prepare for and respond to disturbance from major hurricanes. In an article published in the journal Forest Ecology and Management, John Stanturf, Scott Goodrick, and Ken Outcalt from the Forest Service Southern Research Station (SRS) unit in Athens, GA, r ... more No Easy Solution To Indonesian Haze Problem 
Singapore (AFP) April 20, 2007There is no easy solution to the Indonesian haze which has blighted southeast Asia every year for the past decade, a UN-backed conference on climate change was told Friday. Experts said the problem, largely caused by using fire to clear land for agriculture, is not simply about preserving the environment but also involves addressing poverty and changing traditional practices. Smoggy haze f ... more More Nutritious And Less Toxic 
Hanover NH (SPX) Apr 24, 2007Research led by Dartmouth scientists found that animals fed nutritious, high-quality food end up with much lower concentrations of toxic methylmercury in their tissues. The result suggests ways in which methylmercury-a neurotoxin that can accumulate to hazardous levels-can be slowed in its passage up the food chain to fish. "This research provides evidence that by eating high-quality food, ... more |
