Biologists and botanists are particularly excited by the project; they believe that close study of the flora and fauna in this artificial environment will improve our understanding of the delicately balanced ecological systems of the earth. But the many applications of Biosphere two are not just earth-bound; lessons learned from the project could have profound implications by paving the way for the creation of future colonies in space.

It is the vision of Academic Journals to publish research articles in all areas of human study without financial restriction to readers using the open access model of publication. We strongly believe that the open access model will spur research across the world especially as researchers gain unrestricted access to high quality research articles

Environmentalists have hailed recent announcements by the US Interior Department that purport to protect wildlife, but both of these announcements carry with them asterisks that should give greens pause. On Friday, the Interior Department's Bureau of Land Management announced that some 340 square miles of ecologically sensitive land in the northeast section of Alaska's National Petroleum Reserve will be off limits to drilling.

The U.S. environmental movement is failing - by any measure, the state of the earth has never been more dire. What's needed, a leading environmentalist writes, is a new, inclusive green politics that challenges basic assumptions about consumerism and unlimited growth. by james gustave speth A specter is haunting American environmentalism - the specter of failure. All of us who have been part of the environmental movement in the United States must now face up to a deeply troubling paradox: Our environmental organizations have grown in strength and sophistication, but the environment has continued to go downhill, to the point that the prospect of a ruined planet is now very real. How could this have happened?

Algae could be used as a biofuel while simultaneously cleaning up the environment, report researchers at the University of Virginia. By feeding algae extra carbon dioxide - the principle greenhouse gas contributing to climate change - and organic material like sewage, environmental engineering professors Andres Clarens and Lisa Colosi believe they can boost algae oil yields to as much as 40 percent by weight, far in excess of what can be generated from soybeans.

Concerns over the destruction of the Brazilian rainforest resurfaced at the weekend after it emerged that deforestation jumped by 64% over the last 12 months, according to official government data. Brazil's National Institute for Space Research this week said that around 3,145 square miles - an area half the size of Wales - were razed between August 2007 and August 2008.

If the U.S. moved aggressively to start harnessing the solar power it receives daily, it could generate enough clean energy to meet the country's needs many times over, according to a new report from Environment Florida.

The head of the U.S. Environmental Protection Agency lied to Congress about his rejection of a request from California meant to curb global warming emissions, Sen. Barbara Boxer said on Tuesday. Boxer, a California Democrat who has called for EPA chief Stephen Johnson to resign, made the statement at a hearing on regulation of greenhouse gases under the U.S. Clean Air Act.

Energy and environmental leaders, including representatives from the Nature Conservancy, the World Wildlife Fund, and the Pew Environment Group, recently met with members of President-elect Obama's transition team. The groups came carrying a monstrosity of a document that describes their recommendations on energy and environmental issues for the new administration. The 391-page report, entitled "Transition to Green," was made available Monday on Obama's transition Web site. The environmental groups had suggestions for a wide swath of federal departments, from Energy to Education and Homeland Security to Defense.

Scientists at The Nature Conservancy in Montana have completed the first analysis of where wind generation facilities can be located with minimal risk to the state's wildlife and the environment. Wind provides great promise for a clean and renewable source of energy, but each year wind generation facilities kill tens of thousands of birds and important pollinators such as bats. . And yet, wind energy development has moved forward with very little science-based analysis that might help prevent this kind of environmental harm. The impacts of wind generation are greater than just the immediate airspace. Most turbines take up 40-100 acres of land, so large-scale wind farms can span thousands of acres. Each facility also requires roads and transmission corridors.

The challenges our society faces with depleted energy resources, water shortages, soaring food costs all point to environmental solutions.

John D. Podesta unveils a new program to create good jobs and build a low-carbon economy.

New greenhouse gases emitted in making flat-screen televisions or some refrigerants might be capped under a planned U.N. treaty to combat global warming, delegates at U.N. talks in Ghana said on Friday. Emissions of the recently developed industrial gases, including nitrogen trifluoride and fluorinated ethers, are estimated at just 0.3 percent of emissions of conventional greenhouse gases by rich nations. But the emissions are surging.

A four-square-kilometre chunk has broken off Ward Hunt Ice Shelf - the largest remaining ice shelf in the Arctic - threatening the future of the giant frozen mass that northern explorers have used for years as the starting point for their treks. Scientists say the break, the largest on record since 2005, is the latest indication that climate change is forcing the drastic reshaping of the Arctic coastline, where 9,000 square kilometres of ice have been whittled down to less than 1,000 over the past century, and are only showing signs of decreasing further.
