The gap between Democrats and Republicans who believe global warming is happening increased 30 percent between 2001 and 2010 - a "depressing" trend that's essentially keeping meaningful national energy policies from being considered, argues sociologist Aaron M. McCright.

In the search for better ways to make more energy-efficient buildings, Leidy Klotz isn't exactly looking for ways to improve the engineering. He's seeking ways to improve the engineer.

Mediterranean landscapes have undergone great change in recent decades, but species have adapted to this, at least in the case of roe deer, Spanish ibex, red deer and wild boar. This has been shown by Spanish researchers who have analysed the effects of changes in land use on the past, present and future distribution of these species.

Conventional silicon-based rigid solar cells generally found on the market are not suitable for manufacturing moldable thin-film solar cells, in which a transparent, flexible and electrically conductive electrode collects the light and carries away the current. A woven polymer electrode developed by Empa has now produced first results which are very promising, indicating that the new material may be a substitute for indium tin oxide coatings.

Because the surface of Mars today is bone-dry and frozen all year round, it's difficult to find any place on Earth that is truly Mars-like. But two locations, Antarctica's Upper Dry Valleys and the hyper-arid core of Chile's Atacama Desert, come close. They have become magnets for scientists who want to understand the limits of life on Earth and the prospects for life on Mars.

Active efforts are required to preserve biodiversity in the seas - that far most people are in agreement. But in our enthusiasm to save uncommon species, we sometimes miss the common species that form the basis of marine ecosystems. 'Change strategy' is the challenge to the authorities from researchers at the University of Gothenburg, Sweden.

Google and the subsidiaries of two Japanese companies are investing $500 million in a wind farm being built in the northwestern US state of Oregon.

The old saying there's plenty more fish in the sea might soon no longer apply to the Mediterranean, says Swiss-based International Union for Conservation of Nature. A study it is releasing Tuesday, April 19, 2011 says more than 40 species of marine fish there could soon disappear - almost half the species of sharks and rays and at least 12 species of bony fish are threatened with extinction due to overfishing, pollution and loss of habitat.

Researchers in America have shown that ozone -- a known pollutant at low levels in the earth's atmosphere, causing harmful effects on the respiratory system and sensitive plants -- can be reduced, on average, when electric vehicle charging is done at night time.

Psychologists are offering new insight and solutions to help counter climate change, while helping people cope with the environmental, economic and health impacts already taking a toll on people's lives, according to a special issue of American Psychologist, the American Psychological Association's flagship journal.

thanks to a research project that is the next best thing to time travel, DeJong is measuring the duck eggs in several museum collections - from the Smithsonian Institution, in this case, where Bendire was the first curator of the discipline known as oology, or the study of birds' eggs. When her project is done, DeJong will have assembled and analyzed a metrics database on perhaps 60,000 duck eggs representing at least 40 species and subspecies of ducks found in North America.

The gamitana fish, a close relative of the flesh-eating piranha, mostly eats fruit and can carry seeds down the Amazon River as far as 3 miles (5 kilometers), reports a new Cornell study, making it one of the longest seed dispersals ever reported. The researchers report that these fish (Colossoma macropomum, known as gamitana in Peru, and tambaqui in Brazil) may play an important role in the structure of the Amazon forest as fruit seeds remain viable in their gut for many days and are widely spread.

Thousands of hectares of tropical dry forests in the Brazilian state of Minas Gerais are now safe from logging, thanks to scientists affiliated with a project called Tropi-Dry.

As scientists continue to be baffled over the recent decline in bee populations around the world, a new model developed by Dr Andrew Barron at Macquarie University in collaboration with David Khoury and Dr Mary Myerscough at the University of Sydney, might hold some of the answers to predicting bee populations at risk.

Sarah Saurer was seven years old when she was diagnosed with brain cancer. Her parents soon found out that several other children in their small town -- which sat just miles away from two troubled Illinois nuclear power plants -- had been diagnosed with brain cancer and leukemia. Then news broke that one of the plants had been leaking radioactive water for years before it was detected. A quick survey by concerned mothers found that every single home within a quarter mile of the spill housed someone who'd been diagnosed with cancer. "I want to remind you how important it is to protect people from the harmful things that are being put into our environment," Sarah Saurer told the scientists, her short stature and child-like face showing little sign of her 17 years.

he car of the future could be propelled by a fuel cell powered with hydrogen. But what will the fuel tank look like? Hydrogen gas is not only explosive but also very space-consuming. Storage in the form of very dense solid metal hydrides is a particularly safe alternative that accommodates the gas in a manageable volume. As the storage tank should also not be too heavy and expensive, solid-state chemists worldwide focus on hydrides containing light and abundant metals like magnesium.

According to a new research study, Europeans are happier when they have a day off and work less, while their American counterparts would rather be working those extra hours. Published in the Journal of Happiness Studies, the research, led by Adam Okulicz-Kozaryn from the University of Texas, looks at survey results of Europeans and Americans and how they identified being happy.

Daily temperature fluctuations, not just high temperatures, play a significant role in the transmission of dengue, a deadly mosquito-borne disease that strikes millions of people in tropical and subtropical countries, according to ground-breaking research led by French, Thailand and U.S. scientists and conceived by medical entomologist Thomas Scott of the University of California, Davis.

The European Union's Working Party on Data Protection has issued five recommended requirements for the protection of personal privacy in a time of Smart Meters in the home (PDF). Below is what the group says needs to happen in order to gain the benefits of Smart Metering data while minimizing the risk and cost to personal privacy. 

The United States cannot rule out another oil disaster in its waters, the official who led the response to last year's Gulf of Mexico spill told AFP, as the country marks one year since the tragedy.
