A controversial method of drilling for natural gas, called fracking, has boomed in recent years—as have concerns over its potential to cause environmental contamination and harm human health. But a major review of the practice uncovered no signs that it is causing trouble below ground. “We found no direct evidence that fracking itself has contaminated…

When one thinks of iron one thinks of a dull grey solid. Transparent iron is an odd thought. The effect of electromagnetically induced transparency (EIT) is a known phenomena from laser physics. With intense laser light of a certain wavelength it is possible to make a non-transparent material transparent for light of another wavelength. This…

A unique group of fish that has evolved to live in Antarctic waters thanks to anti-freeze proteins in their blood and body fluids is threatened by rising temperatures in the Southern Ocean, according to a new study by Yale. The development of antifreeze glycoproteins by notothenioids, a fish family that adapted to newly formed polar…

China produces electricity for its burgeoning economy with its ample coal reserves. A full 80 percent comes from coal-burning power plants, and new plants are being constructed all the time. The country’s reliance on coal power, while causing very dirty pollution, also has an interesting side effect. It takes away the “greenness” of electric vehicles.…

Volkswagen’s Chattanooga, Tennessee facility has achieved the world’s first LEED-Platinum green building certification for an automotive manufacturing plant. The $1 billion production facility makes the 2012 Passat.

The world must develop different indicators on sustainable development that are not biased against developing countries, a major conference has heard. Bharrat Jagdeo, former president of Guyana, said current assessments and rankings use indicators such as access to potable water and sanitation, or malaria levels, which automatically rank developed countries higher.

The Chinook salmon, Oncorhynchus tshawytscha, is the largest species in the pacific (Oncorhynchus) salmon family. Other commonly used names for the species include King salmon, Quinnat salmon, Spring salmon and Tyee salmon. Chinook are an anadromous fish native to the north Pacific Ocean and the river systems of western North America ranging from California to…

The world’s biggest offshore wind farm was officially opened today after record-fast construction in the middle of the Irish Sea. The 102 turbines of the two connected Walney wind farms cover an area of 73 square-kilometres and were formally connected to the National Grid in a ceremony today. With a capacity of 367.2MW, the huge…

Estimates from satellite monitoring suggest the melt rate from the Himalayas and other high-altitude Asian mountains in recent years was much less than what scientists on the ground had estimated, but those monitoring the satellite data warn not to jump to the skeptical conclusion. The region’s ice melt from 2003-2010 was estimated at 4 billion…

Marguerite Bay or Margaret Bay is an extensive bay on the west side of the Antarctic Peninsula, which is bounded on the north by Adelaide Island and on the south by Wordie Ice Shelf, George VI Sound and Alexander Island. A new paper reports glacial geological data that provide evidence for the timing of ice-sheet…
