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 |

Nuclear Power Not The Solution For China Says Official
Beijing (AFP) April 23, 2007Nuclear power is not the long-term answer to China's energy needs due to limited global uranium supplies and problems with nuclear waste disposal, state media on Monday quoted a top official as saying. "Nuclear power cannot save us because the world's supply of uranium and other radioactive minerals needed to generate nuclear power are very limited," Chen Mingde, vice chairman of the Natio ... read more Why GNEP Can Not Jump To The Future 
Washington DC (SPX) Apr 24, 2007Congress is now considering whether to approve or zero out the $405 million that President Bush is proposing to spend in fiscal year 2008 on the Global Nuclear Energy Partnership (GNEP)-a program aimed at rendering plutonium inert in nuclear weapons but still useful in nuclear power plants. Nuclear experts at the National Academy of Sciences have long questioned the practicability of the t ... more Biodiesel Will Not Drive Down Global Warming 
London UK (SPX) Apr 24, 2007EU legislation to promote the uptake of biodiesel will not make any difference to global warming, and could potentially result in greater emissions of greenhouse gases than from conventional petroleum derived diesel. This is the conclusion of a new study reported in Chemistry and Industry, the magazine of the SCI. Analysts at SRI Consulting compared the emissions of greenhouse gases by the ... more India And Japan Sign Pact On Global Warming 
Tokyo (AFP) April 23, 2007Japan signed a deal Monday to help fast-growing India fight global warming as the two countries look ahead to a framework after the landmark Kyoto Protocol expires in 2012. Under the agreement, Japan will invest in India's energy industry and transfer energy-saving technology. It comes two weeks after Japan sealed a similar agreement with China during a landmark visit here by Chinese Premi ... more Buried Residual Oil Is Still Affecting Wildlife Decades After A Spill 
Bell House MS (SPX) Apr 24, 2007Nearly four decades after a fuel oil spill polluted the beaches of Cape Cod, researchers have found the first compelling evidence for lingering, chronic biological effects on a marsh that otherwise appears to have recovered. Through a series of field observations and laboratory experiments with salt marsh fiddler crabs (Uca pugnax), doctoral student Jennifer Culbertson and colleagues found ... more Everything Starts With Recognition 
Munich, Germany (SPX) Apr 24, 2007A human body has more than 10 to the power of 27 molecules with about one hundred thousand different shapes and functions. Interactions between molecules determine our structure and keep us alive. Researchers at the Max Planck Institute for Solid State Research in Stuttgart in collaboration with scientists from the Fraunhofer Institute in Freiburg and the King's Collage London have followe ... more |
