Geologists Reveal Secrets Behind Supervolcano Eruption
Troy, NY (SPX) Mar 07, 2007Researchers at Rensselaer Polytechnic Institute have discovered what likely triggered the eruption of a "supervolcano" that coated much of the western half of the United States with ash fallout 760,000 years ago. Using a new technique developed at Rensselaer, the team determined that there was a massive injection of hot magma underneath the surface of what is now the Long Valley Caldera in California some time within 100 years of the gigantic volcano's eruption. Forest Replacing Tundra At Rapid Rate 
Edmonton, Canada (SPX) Mar 07, 2007Forests of spruce trees and shrubs in parts of northern Canada are taking over what were once tundra landscapes--forcing out the species that lived there. This shift can happen at a much faster speed than scientists originally thought. The findings add to the body of evidence on climate change. Researchers Reconstruct Spread Of Bird Flu From China 
Washington (AFP) Mar 06, 2007US researchers have reconstructed the evolution of avian flu and its spread over the past decade from its first origins in southern China, according to a new study. The team from Irvine University in California combined genetic and geographic data for the H5N1 virus, identifying many of the migration routes through which the strains spread across Asia and then around the globe. |
Pollution From China And India Affecting Global Weather
College Station TX (SPX) Mar 07, 2007Severe pollution from the Far East is almost certainly affecting the weather near you, says a Texas A and M University researcher who has studied the problem and has published a landmark paper on the topic in the Proceedings of the National Academy of Sciences. Hidden Ice Lakes Speed Ice Flow Into Ocean 
New York NY (SPX) Mar 07, 2007Just as explorers once searched the vast reaches of Africa's Nile River for clues to its behavior and ultimate source, modern-day scientists are searching Antarctica for its hidden lakes and waterways that can barely be detected at the surface of the ice sheet. In a new study, researchers have unearthed how water from this vast subglacial system contributes to the formation of ice streams, and how it plays a crucial role in transporting ice from the remote interior of Antarctica toward the surrounding ocean. Some Corals Might Be Able To Fight The Heat 
Ithaca NY (SPX) Mar 05, 2007While humans can survive large temperature fluctuations, such species as corals are only comfortable within a 12-degree temperature range. And rising global temperatures appear to be threatening their survival, according to Drew Harvell, Cornell professor of ecology and evolutionary biology. |

Advanced Technology Peers Deep Inside Hurricanes
Greenbelt MD (SPX) Mar 07, 2007Determined to understand why some storms grow into hurricanes while others fizzle, NASA scientists recently looked deep into thunderstorms off the African coast using satellites and airplanes. During July and August 2006, a team of international scientists, including NASA researchers, journeyed to the west coast of Africa. Australia To Push For Permanent End To Japanese Whaling 
Sydney (AFP) March 05, 2007Australia has vowed to pursue its battle to ban whaling for scientific purposes after Japan cut short this year's whale hunting season in the Antarctic following a fire on its mother ship. The pledge came as environmental groups celebrated Tokyo's decision to cut short the 2006-2007 season, but stepped up pressure on it to abandon the controversial practice forever. China Bans New Internet Cafes 
Beijing (AFP) Mar 07, 2007China banned any more cybercafes from opening this year, the latest move by the nation's communist rulers to restrict the rising influence of the internet. Chinese authorities will not approve any more internet cafe licences in 2007, according to a notice posted on the culture ministry's website. |
Why Do Birds Migrate
Tucson AZ (SPX) Mar 07, 2007Why do some birds fly thousands of miles back and forth between breeding and non-breeding areas every year whereas others never travel at all? One textbook explanation suggests either eating fruit or living in non-forested environments were the precursors needed to evolve migratory behavior. Not so, report a pair of ecologists from The University of Arizona in Tucson. The pressure to migrate comes from seasonal food scarcity. Whole Body Regeneration From A Blood Vessel 
Haifa, Israel (SPX) Mar 07, 2007For a lucky subset of vertebrates, losing an appendage is no big deal. As many an inquisitive child knows, salamanders can regenerate lost limbs or tails; and as lab investigators know, zebrafish can regrow lost fins. Of course, humans and other "higher" vertebrates must make do with repairing rather than regenerating damaged tissues. Engineers Share Designs On Clean Water 
Cambridge MA (SPX) Mar 07, 2007An MIT engineer working toward clean drinking water in Nepal describes in a recent issue of the Journal of International Development how people from developed and developing countries can work together to solve key humanitarian problems, ultimately meeting the basic human needs for security, broadly defined. |
