The University of Arizona (UA) conducted a study on refrigerator water filtration devices and chemical removal effectiveness.
Does it matter whether long periods of hot weather happen in June or July, August or September? Scientists studying the subtle effects of heat waves and droughts say that when such events happen makes a big difference.
Anthropogenic climate warming is leading to consideration of options for geoengineering to offset rising carbon dioxide levels. One potential technique involves injecting artificial sea spray into the atmosphere. The sea salt particles would affect Earth's radiation budget directly, by scattering incoming solar radiation, and indirectly, by acting as cloud condensation nuclei, which could lead to whiter clouds that reflect more radiation.
Farms that aim for high food production using environmentally friendly practices could be better for the environment than both organic and conventional farms.
The next generation of wind energy facilities in the United States may be built offshore where winds are stronger, floating platforms could be utilized, and links to power grids may already exist.
By combining airborne laser technology, satellite mapping, and ground-based plot surveys, a team of researchers has produced the first large-scale, high-resolution estimates of carbon stocks in remote and fragile Madagascar.
Air pollution, even at levels generally considered safe by federal regulations, increases the risk of stroke by 34 percent, according to researchers from Beth Israel Deaconess Medical Center, a patient care, teaching and research affiliate of Harvard Medical School.
Gaëtan Girardin, researcher in nuclear engineering, gives us the key to understanding nuclear reactor safety. While the disaster at Fukushima is at the center of our conversation, the recent and minor incident at the Mühleberg plant (Switzerland) is also discussed.
Recent cuts to the scientific workforce of Environment Canada, a government agency responsible for meteorological services and environmental research, threaten scientific research related to the ozone layer in the upper atmosphere and pollution in the lower atmosphere, according to environmental scientists in the U.S. These reductions in personnel and projected budget cuts also threaten existing international agreements.
A recent study found that children living near coal-tar-sealed pavement are likely to receive a far higher dose of carcinogenic polycyclic aromatic hydrocarbons (PAHs) from incidental ingestion of house dust than do children living near unsealed pavement, and that dose is more than two times higher than the PAH dose children are estimated to receive from food.
Fuel economy of all new vehicles sold in the United States last month was at its highest mark ever, say researchers at the University of Michigan Transportation Research Institute.
The Obama Administration recently proposed a FY 2013 budget of $8.344 billion for the U.S. Environmental Protection Agency (EPA). This budget reflects a government-wide effort to reduce spending and find cost-savings, and is $105 million below the EPA’s enacted level for FY 2012.
Electric cars have been heralded as environmentally friendly, but findings from University of Tennessee, Knoxville, researchers show that electric cars in China have an overall impact on pollution that could be more harmful to health than gasoline vehicles.
With the sweat from 2011’s record-setting temperatures just now drying off and projections of a continued drought cycle reamins for Central Texas, discussion about securing current and future water supplies is becoming increasingly urgent.
Researchers at Montana State University-Northern have developed a process to convert camelina oil to jet fuel and other high-value chemicals. MSU has applied for a U.S. patent and research is ongoing.
Companies have successfully developed more than150 alternatives to long-chain perfluorinated chemicals.
Advances in studying genes mean that scientists in evolutionary developmental biology or “evo-devo” can now explain more clearly than ever before how bats got wings, the turtle got its shell and blind cave fish lost their eyes, says University of Massachusetts Amherst evolutionary biologist Craig Albertson.
Whether it’s building an oil pipeline, drilling for fuel in the ocean or “fracking” to flush natural gas out of the Earth, we’re often asked to believe the process is safe, when companies want to do something that could have big benefits. But that process also could be potentially disastrous for the environment.
Mushy tomatoes, brown bananas and overripe cherries -- to date, waste from wholesale markets has ended up on the compost heap at best. In future it will be put to better use: Researchers have developed a new facility that ferments this waste to make methane, which can be used to power vehicles.
Roofing materials that double as solar panels and can also moderate the temperature of buildings are among the next-generation building products being developed at UNSW.
