Catching Fog
"This is one of the best beers that I have ever tried," says AndrÃ©s Barrera. My friend is enjoying a craft beer called Atrapaniebla â€” Spanish for fog catcher â€” an ale made with water condensed from mountain fog on two fog catchers. The microbrewery that produces it, located in PeÃ±a Blanca (some 360 kilometres north of Santiago, the Chilean capital), is one of the first Chilean enterprises to make use of fog-catching technology; others use it to water tomato and aloe vera crops. "Water from fog catchers has less nitrite and nitrate than the drinking water in the north of Chile, which is good for beer," says Miguel Ãngel Carcuro, 29-year-old co-owner of the microbrewery that makes Atrapaniebla. Of course, while beer is nice, water is essential and fog catchers can be a great way to provide this sometimes scarce commodity. Carcuro's interest in this technology stems from teenage travels with his father, who showed him a hill above the bay of Chungungo, where there were the remains of fog catchers that had until recently provided water for 100 families. >> Read the Full Article
How Cutting Emissions Pays Off
Lower rates of asthma and other health problems are frequently cited as benefits of policies aimed at cutting carbon emissions from sources like power plants and vehicles, because these policies also lead to reductions in other harmful types of air pollution. But just how large are the health benefits of cleaner air in comparison to the costs of reducing carbon emissions? >> Read the Full Article
Drought Causes Western US to Rise
Severe drought affecting the western United States in recent years is not only influencing water restrictions for residence and creating problems for crops and wildlife, but it's changing the landscape by causing land to rise up in elevation. >> Read the Full Article
Study shows sunlight, not microbes dominate CO2 production in Arctic
Just how much Arctic permafrost will thaw in the future and how fast heat-trapping carbon dioxide will be released from those warming soils is a topic of lively debate among climate scientists. To answer those questions, scientists need to understand the mechanisms that control the conversion of organic soil carbon into carbon dioxide gas. Until now, researchers believed that bacteria were largely responsible. >> Read the Full Article
NASA reports unknown source of banned ozone-destroying compound
NASA research has revealed the Earth's atmosphere contains an unexpectedly large amount of an ozone-depleting compound from an unknown source decades after the compound was banned worldwide. Carbon tetrachloride (CCl4), which was once used in applications such as dry cleaning and as a fire-extinguishing agent, was regulated in 1987 under the Montreal Protocol along with other chlorofluorocarbons that destroy ozone and contribute to the ozone hole over Antarctica. Parties to the Montreal Protocol reported zero new CCl4 emissions between 2007-2012. >> Read the Full Article
New Satellite To Help Farmers Facing Drought
Satellites are put into orbit for a variety of tasks. From sending television signals to our homes to enabling GPS devices, to helping us see weather on a global scale, satellites collect information and provide us with modern conveniences. One new use for a proposed satellite scheduled to launch this winter is soil moisture monitoring at a local level. >> Read the Full Article
Harnessing High-Altitude Wind Energy
Researchers have discovered that the world's energy needs could easily be met by harnessing the power potential of high-altitude winds. Developers in an emerging field known as airborne wind energy envisage using devices that might look like parachutes or gliders to capture electricity from the strong, steady winds that blow well above the surface in certain regions. >> Read the Full Article
Bottling Water from Drought Stricken Areas
The bottled water industry has grown exponentially the past few decades despite the fact tap water in the United States is generally safe. Never mind the fact bottled water producers have had more than their fair share of safety issues: bottled water has become accepted by consumers. While companies such as NestlÃ© insist they are taking responsibility for water stewardship and recycling, they also bottle their water at dubious sources, including those in drought stricken regions. >> Read the Full Article
The importance of maintaining seagrass
Seagrass meadows provide the ideal place for young fish to thrive, say NERC-funded scientists researching the importance of these habitats for commercial fishing. Globally seagrasses are being lost at the same rate as Amazonian rainforests, and little is being done to conserve these habitats as their importance isn't fully understood. But scientists at Swansea University have just published two studies in the journals Marine Pollution Bulletin and Marine Biodiversity showing these areas are vital to the wellbeing of juvenile fish, and consequently the fishing industry. >> Read the Full Article
Icequakes triggered by earthquakes
In 2010, a powerful magnitude-8.8 earthquake struck off the coast of central Chile, rocking much of the country and producing tremor as far away as Argentina and Peru. But a new study suggests its effects were felt even farther awayâ€”in Antarctica. In the wake of the Maule temblor, the scientists found, several seismic stations on the frozen continent registered "ice quakes," probably due to fracturing of the ice as the planet's crust shook. Earthquakes are already known to affect Antarcticaâ€™s ice shelves, thanks to the tsunamis they can spawn. Tsunami waves can propagate for great distances across the ocean; if the waves reach Antarcticaâ€™s ice shelves - the floating platforms of ice surrounding the continentâ€”they can push and pull on the ice, promoting fractures and ultimately helping large chunks of ice break off, or calve. >> Read the Full Article
