Decades of accumulated change court ecosystem catastrophe
Subjected to decades of gradual change by humans, many of the world’s natural ecosystems – from coral reefs and tropical forests to northern lakes and forests – appear susceptible to sudden catastrophic ecological change, an international consortium of scientists reports Thursday October 11 in the journal Nature. “Models... view more...

Lupus more severe in patients with Southern European ancestry
ystemic lupus erythematosus (SLE) patients with a higher percentage of ancestry from southern Europe have more severe disease manifestations, according to new research presented today at EULAR 2008, the Annual Congress of the European League Against Rheumatism in Paris, France. view more (2008-06-12)
Research Probes Soy - Prostate Cancer Link
Researchers at the University of Ulster and Belfast City Hospital are set to launch a groundbreaking study that could offer a new insight into the prevention of prostate cancer. The study will focus on a significant link between low levels of serious prostate cancer and the presence of soy products in the diet. Professor Ian Rowland, from the... view more... (2002-07-30)
Wiping out the world's mass migrations
Densely packed wildebeests flowing over the Serengeti, bison teeming across the Northern Plains-these iconic images extend from Hollywood epics to the popular imagination. view more (2009-06-02)
Nerve prosthesis developed in Ume'å
The first clinical study ever with a new type of nerve prosthesis has been launched at Northern Sweden University Hospital. It is being carried out by a research team from Ume'å University under the leadership of Professors Jan-Olof Kellerth and Mikael Wiberg. The team, at the Department of Integrative Medical Biology and the Department of... view more... (2003-11-11)
Carnegie scientists fine-tuning methods for Stardust analysis
On Sunday, January 15, NASA's Stardust mission landed safely with the first solid comet fragments ever brought back to Earth. Members of the mission's Preliminary Examination Team, including several from the Carnegie Institution's Geophysical Laboratory and Department of Terrestrial Magnetism, are among the first to analyze these precious samples. view more (2006-03-23)
New Window Opens on the Secret Life of Microbes: Scientists Develop First Microbial Profiles of Ecosystems
Nowhere is the principle of "strength in numbers" more apparent than in the collective power of microbes: despite their simplicity, these one-cell organisms--which number about 5 million trillion trillion strong (no, that is not a typo) on Earth--affect virtually every ecological process, from the decay of organic material to the... view more...

Decline of world's estuaries and coastal seas
Human activity over the centuries has depleted 90% of marine species, eliminated 65% of seagrass and wetland habitat, degraded water quality 10-1,000 fold, and accelerated species invasions in 12 major estuaries and coastal seas around the world. view more (2006-06-23)
Big vegetarian mammals can play a critical role in maintaining healthy ecosystems, study finds
Removing large herbivorous mammals from the African savanna can cause a dramatic shift in the relative abundance of species throughout the food chain. view more (2007-01-17)
When fish become extinct, the cycling of critical nutrients in ecosystems changes, Cornell study finds
Ecosystems are such intricate webs of connections that few studies have been able to explore exactly what happens when a species dies out. view more (2007-03-05)
Long-term study shows effect of climate change on animal diversity
Two species of giraffe, several rhinos and five elephant relatives, along with multitudes of rodents, bush pigs, horses, antelope and apes, once inhabited what is now northern Pakistan. view more (2008-09-23)
Mixed Marriages in NI more acceptable, more popular, University of Ulster Survey finds
Mixed marriages between Protestants and Catholics in Northern Ireland are becoming more acceptable - and more popular, according to new research from the University of Ulster. The findings of the survey, part of the Life and Times series, were presented at an international workshop in Belfast this week organised by INCORE and the Institute for... view more... (2001-11-30)
Plan to conserve forests may be detrimental to other ecosystems
Conserving biodiversity must be considered when developing plans to reduce greenhouse gas emissions from deforestation, researchers warn in today's edition of Science. view more (2008-06-13)
Scientists aim to bring indigenous people into climate change monitoring and policy
Scientists at the Missouri Botanical Garden are calling for the inclusion of indigenous peoples around the world in helping monitor the effects of global climate change and develop policy. view more (2009-05-13)
How fish species suffer as a result of warmer waters
Ongoing global climate change causes changes in the species composition of marine ecosystems, especially in shallow coastal oceans. view more (2007-01-05)
Sunquakes Reveal The Solar Furnace
Most people are familiar with the fact that sensitive instruments known as seismographs can detect earthquakes taking place many hundreds or thousands of miles away. By studying the waves from these tremors, scientists can find out about the conditions deep inside our rocky planet. In the same way, astronomers are now able to measure millions... view more...

Grazer diversity counteracts plant diversity effects on ecosystem functioning in seagrass beds
Several influential experiments have shown that high plant diversity enhances ecosystem productivity, animal diversity, and invasion resistance. Yet theory predicts that plant and herbivore diversity, which often co vary in nature, should have countervailing effects on ecosystem properties. In the July issue of Ecology Letters, Duffy, Canuel, and... view more... (2003-07-02)
Satellite data reveals extreme summer snowmelt in northern Greenland, CCNY professor says
The northern part of the Greenland ice sheet experienced extreme snowmelt during the summer of 2008, with large portions of the area subject to record melting days. view more (2008-10-09)
Oldest dated evidence of cattle in southern Africa found
A team of researchers working with colleagues from the Botswana National Museum shed new light on the questions of when cattle were brought to southern Africa and from where. view more (2005-08-03)
Breakthrough made in assessing marine phytoplankton health
Researchers from Oregon State University, NASA and other organizations said today that they have succeeded for the first time in measuring the physiology of marine phytoplankton through satellite measurements of its fluorescence - an accomplishment that had been elusive for years. view more (2009-05-29)
