Study provides new understanding of forces behind seasonal flu virus evolution
Do influenza viruses persist in low levels year-round in the northern and southern hemispheres, or does a new crop of the virus emerge afresh in tropical zones such as Southeast Asia before spreading into temperate regions around the globe" Researchers have provided an answer to this long-standing question: new strains arise each year. view more (2008-04-17)
Invasive plants prefer disturbance in exotic regions over home regions
One of the most invasive exotics in the western United States, the yellow starthistle, is successful both at "invasion" in non-native areas and "colonization" in native ones. view more (2006-07-27)
Dr A.H. Heineken Prize for Environmental Sciences 2002 for Lonnie G. Thompson
The Royal Netherlands Academy of Arts and Sciences has awarded the Dr A.H. Heineken Prize for Environmental Sciences 2002 (USD 150,000) to Professor Lonnie G. Thompson Byrd Polar Research Center, Ohio State University, United States ‘for his pioneering work in research into ice cores in the polar regions and the tropics’. The... view more... (2002-04-15)
Predicting the weather on Titan?
Using recent Cassini, Huygens and Earth-based observations, scientists have been able to create a computer model which explains the formation of several types of ethane and methane clouds on Titan. view more (2006-01-24)
Robot plumbs Wisconsin lake on way to Antarctica, jovian moon
A University of Illinois at Chicago scientist will lead a team testing a robotic probe in a polar-style, under-ice exploration that may have out-of-this world applications. view more (2008-02-12)
Scientists should look at their own carbon footprint
Scientists studying the impact of climate change on the Arctic need to consider ways to reduce their own carbon footprints, says a researcher who regularly flies north to study the health of caribou. view more (2009-06-09)
Antarctic expedition provides new insights into the role of the Southern Ocean for global climate
In the Southern Ocean, large quantities of surface-drifting plankton algae are able to significantly reduce the carbon dioxide content of the surface waters, which can affect the global carbon dioxide cycle. view more (2008-02-06)
Aurora Borealis breaks new grounds - and old ice
It can crush ice sideways and stay precisely on station to an accuracy of a metre. It can drill a hole 1,000 metres deep into the seabed while floating above 5,000 metres of ocean and it can generate 55 megawatts of power. So far, Aurora Borealis is the most unusual ship that has never been built, and it represents a floating laboratory for... view more... (2007-12-03)
Cassini finds recent, unusual geology on Enceladus
New detailed images taken by NASA's Cassini spacecraft of the south polar region of Saturn's moon Enceladus reveal distinctive geological features, and the most youthful terrains of any seen on Enceladus. view more (2005-07-27)
Scientists probe Antarctic glaciers for clues to past and future sea level
Scientists from the U.S., U.K. and Australia have teamed up to explore two of the last uncharted regions of Earth, the Aurora and Wilkes Subglacial Basins, immense ice-buried lowlands in Antarctica with a combined area the size of Mexico. view more (2008-10-28)
IARC scientists document warm water surging into Arctic
Scientists at the University of Alaska Fairbanks International Arctic Research Center this fall documented that recent surges of warm water from the North Atlantic Ocean continue to pulse into the Arctic Ocean and are moving toward Alaska and the Canadian Basin. view more (2006-09-27)
Cranfield University Reaches Remoter Regions
The Third Air Transport in Remoter Regions Forum, organised by Cranfield University and recently held in Cork, Ireland, proved the ideal platform for Cranfield to announce the establishment of their Air Transport in Remoter Regions Research Centre. The centre aims to provide an international focal point for the dissemination of expert knowledge... view more... (2003-06-16)
Less Arctic ice means higher risks, experts warn
The International Ice Charting Working Group predicts more marine transportation in the Arctic as sea ice continues to diminish and warns of "significant hazards to navigation," according to a statement released yesterday. view more (2007-10-29)
New insight into brain disorders
The function of an enzyme in the brain - strongly linked to a number of major brain diseases such as Alzheimer's, schizophrenia and bi-polar disorder - has been identified for the first time by researchers at the University of Bristol, UK. view more (2007-03-01)
First global bird map provides new clues to future extinctions
The first global survey of bird diversity could play a key role in identifying species most vulnerable to extinction, researchers report today in the journal PLoS Biology. view more (2006-06-20)
Climate kick from the Southern Ocean
This much was already known: in the closing phase of the last ice age the Southern Hemisphere began warming first. As a result, the Antarctic sea ice melted. It was at least a thousand years later - as evidenced by investigations of Greenland ice cores - that the high northern latitudes began to get warmer. Sea ice in the North Atlantic retreated... view more... (2003-07-29)
Researchers establish common seasonal pattern among bacterial communities in Arctic rivers
New research on bacterial communities throughout six large Arctic river ecosystems reveals predictable temporal patterns, suggesting that scientists could use these communities as markers for monitoring climate change in the polar regions. view more (2009-11-24)
Cosmic dust in ice cores sheds light on Earth's past climate
Each year nearly 40,000 tons of cosmic dust fall to Earth from outer space. Now, the first successful chronological study of extraterrestrial dust in Antarctic ice has shown that this amount has remained largely constant over the past 30,000 years, a finding that could help refine efforts to understand the timing and effects of changes in the... view more...

Advice from research: market visiting rights to Antarctica
Tourism on Antarctica is increasing and that can form a threat for the vulnerable South Pole area. Research from Maastricht University provides a possible solution: market the visitor rights to the highest bidder. view more (2008-09-29)
