It may seem counterintuitive, but one way to reduce carbon dioxide emissions to the atmosphere may be to produce pure carbon dioxide in powerplants that burn fossil fuels. In this way, greenhouse gases – once isolated within a plant – could be captured and stored in natural reservoirs, deep in Earth's crust. Such "carbon-capture" technology may significantly reduce greenhouse gas emissions from cheap and plentiful energy sources such as coal and natural gas, and help minimize...

Liquid-like Materials May Pave Way For New Thermoelectric Devices
2012-03-24 02:49:43

In the continual quest for better thermoelectric materials–which convert heat into electricity and vice versa–researchers have identified a liquid-like compound whose properties give it the potential to be even more efficient than traditional thermoelectrics. Thermoelectric materials have been used to power spacecraft ranging from Apollo to the Curiosity rover now headed for Mars. Recently, however, scientists and engineers have been turning to these materials to use wasted...

Spanish and Danish researchers have developed a method for the in vivo study of the unknown metabolism of selenium, an essential element for living beings. The technique can help clarify whether or not it possesses the anti-tumor properties that have been attributed to it and yet have not been verified through clinical trials. "It is vox populi that doctors around the world recommend selenium supplements to complement traditional therapy against cancer and the AIDS virus but the truth is...

University of Illinois research reports that swine producers can feed distiller's dried grain with solubles (DDGS) to their pigs without concern for sulfur content. "When you buy DDGS, you don't have to be concerned about the level of sulfur it contains because there doesn't appear to be any impact on pig performance," said U of I animal sciences professor Hans Stein. According to the researcher, DDGS, a co-product of the ethanol industry, is used as a feed ingredient in diets fed to...

Iron is key to reversing global warming, Concordia and McGill research shows Canada defines itself as a nation that stretches from coast to coast to coast. But can we keep those coasts healthy in the face of climate change? Yves Gélinas, associate professor in Concordia´s Department of Chemistry and Biochemistry, has found the solution in a surprising element: iron. In a study published in Nature, Gélinas – along with Concordia PhD candidate Karine...

Risks related to the critical nature of arsenic – used to make high-speed computer chips that contain gallium arsenide – outstrip those of other substances in a group of critical materials needed to sustain modern technology, a new study has found. Scientists evaluated the relative criticality of arsenic and five related metals in a report in the ACS' journal Environmental Science & Technology. T. E. Graedel, E. M. Harper, N. Nassar and colleagues explain that five metals...

Study finds protein's entwined arm movements may control fate of potentially toxic payload Like a magician employing sleight of hand, the protein mitoNEET -- a mysterious but important player in diabetes, cancer and aging -- draws the eye with a flurry of movement in one location while the subtle, more crucial action takes place somewhere else. Using a combination of laboratory experiments and computer modeling, scientists from Rice University and the University of California, San Diego...

The appearance of oxygen in the Earth's atmosphere probably did not occur as a single event, but as a long series of starts and stops, according to an international team of researchers who investigated rock cores from the FAR DEEP project. The Fennoscandia Arctic Russia - Drilling Early Earth Project -- FAR DEEP -- took place during the summer of 2007 near Murmansk in the northwest region of Russia. The project, part of the International Continental Scientific Drilling Program,...
