A treatment, not a cure: Calcium silicate neutralizes an acidic stream

...rica have become acidified. When combusted, fossil fuels release sulfur dioxide and nitrogen oxide, the precursors to acid precipitation, into the atmosphere. Persistent exposure to these pollutants, which return to Earth in rain, snow, sleet, hail and fog, can compromise the health of aquatic ecosystems. ...

Taking the next step toward growing our own fuel

...e efficiency of bioconversion of plant fibers into fuels and other value added products. The new theme is the seventh to be chosen for the Institute for Genomic Biology under the direction of Harris A. Lewin, Gutgsell Endowed Chair in the department of animal sciences. Although the building housing the I...

Cars, not crops, should be chief targets in reducing greenhouse gases

...ion to hydrogen vehicles, which now require fossil fuels or other sources of energy to generate the hydrogen. Coupled with changes in the way that agricultural lands are managed, doubling the fuel efficiency of our nation's vehicles seems a logical first step in balancing the carbon budget." ...

Global warming's impact on US plants, animals determined from review of dozens of studies

...olving Parmesan concluded that human use of fossil fuels was primarily responsible for the average hike in temperatures over the past 50 years. Gases released from spent fuel are known to enter the Earth's atmosphere, trapping extra sunlight there similar to the way a greenhouse works. Studies since then h...

...grid. At the same time, the turbine's exhaust heat fuels the world's largest absorption chiller to be fired only by "waste" heat. This "fuel free" chilled water cools one-million-square-feet of building space at a mixed use site. The cooling, heating and power system is expected to operate at 70 to 80 per...

Latest census finds more American pika populations disappear as climate warms

...rapping emissions from the burning of dirty fossil fuels for energy now." Previous research results suggested that American pikas are particularly vulnerable to global warming because they reside in areas with cool, relatively moist climates and are unable to survive even six hours in temperatures as low...

Urban ecology study witnessing the birth of a 'designer ecosystem'

...which comes about because of the burning of fossil fuels in cars. Driving around fertilizes the ecosystem. "Is fertilizing a good thing? One of the things that we are going to do in the next phase is to investigate the consequences," she said. While the team's interest is in doing fundamental ecology resea...

Study in Royal Society journal on managing GM crops for environmental benefit

...support energetic demands. To determine the energy fuels associated with such extended activity, we evaluated plasma concentrations of six key energy metabolites in bar-tailed godwits (Limosa lapponica taymyrensis) caught immediately upon landing after a non-stop migratory flight of 4,500-km. Metabolite da...

Climate change to bring a wave of new health risks

...tection during an acute heat event. But the fossil fuels burned to generate the electricity to drive those air conditioners, as well as over-dependence on electric power grid functioning could potentially exacerbate the problem. "Short-sighted fixes must be avoided," Patz says. Improving deficiencies in su...

'Termite guts can save the planet,' says Nobel laureate

...d. If scientists can convert cellulose into liquid fuels like ethanol, the world's energy supply and storage problems could both be solved at a stroke." This is where the termite guts come in. A billion years of evolution have produced a highly efficient factory for turning cellulose into ethanol, unlike a...

Growth in biomass could put US on road to energy independence

...ase in ethanol production would see transportation fuels from biomass increase from 0.5 percent of U.S. consumption in 2001 to 4 percent in 2010, 10 percent in 2020 and 20 percent in 2030. In fact, depending on several factors, biomass could supply 15 percent of the nation's energy by 2030. Meanwhile, bio...
