Psychosocial stress appears to enhance the lung-damaging effects of traffic-related pollution (TRP) in children, according to new research from the Keck School of Medicine of the University of Southern California (USC) in Los Angeles.
This season’s massive Arizona fires making headlines around the globe have destroyed dozens of structures and burned nearly three-quarters of a million acres. They also are contributing to global warming, scientists say, by upsetting the carbon balance while they are burning and for years to come.
Researchers at Dalhousie University in Halifax and Stanford University in California concluded a two year study called “Tracking apex marine predator movements in a dynamic ocean” published in the science journal Nature released June 22.
Nature can have its own solutions to offer against invasive plant species. In the case of the weed cogongrass, woody vegetation at the forest’s edge may stop its progress. By catching seeds blowing in the wind, shrubs can prevent or lessen the impact of an invasion of weeds that will strangle native plants.
Research is being conducted on degrading a toxic compound found in groundwater systems around the world.
A new report by the Wildlife Conservation Society highlights the critical importance of 1.3 million acres of roadless, public lands in Montana’s spectacular Crown of the Continent Ecosystem. The report recommends that most of these lands be preserved to protect wolverines, bighorn sheep, westslope cutthroat and bull trout, grizzly bears and other vulnerable species in the face of climate change and other threats.
The economic impacts of routine weather events can add up to 3.4% of the nation's GDP.
New research suggests that, in the Athabasca Oil Sands in northern Alberta, human activity related to oil production and the timber industry could be more important than wolves in the decline of the caribou population.
A University of Arkansas researcher and her colleagues studied core sediments from a shallow boreal lake and found that storm activity has increased substantially over the past 150 years. The rise in storm frequency appears to be linked to solar activity, but also may be linked to higher global temperatures resulting from increased amounts of greenhouse gases.
A review published online June 22 ahead of print in the peer-reviewed journal Environmental Health Perspectives (EHP) reports the conclusions of an international workshop on ways to improve chemicals safety testing for effects on the breast. The studies reviewed by workshop scientists indicate that chemical exposures during critical periods of development may influence breast growth, ability to breastfeed, and cancer risk. The scientists recommend that future chemical testing evaluate effects on the breast after prenatal and early-life exposure.
A study focused on a new multiple-pollutant, risk-based approach doubles the health benefits achieved by conventional single contaminant approaches with improved outcomes for the susceptible and vulnerable.
New research lends support to recent studies that suggest abrupt climate change is the result of alterations in ocean circulation uniquely associated with ice ages, not from atmospheric carbon dioxide.
Often touted as the greatest envirnmental achievement of the 20th century, the North American Model of Wildlife Conservation is anything but, say wildlife ecologists and environmental ethicists from Michigan Technological University and Michigan State University.
Crop Science Society of America releases a position statement that calls for research programs to understand crops’ adaptation to drought, heat, and biological stresses from climate change
The 10,000-plus members of the American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America develop a position statement on climate change.
Researchers analyze data collection methods for examining the environmental impacts of pesticide use.
A new Baylor University study has found that sunlight decreases the toxicity of golden algae, which kills millions of fish in the southern United States every year.
Recent research by Matthew VanSchenkhof, a Kansas State University doctoral student, can help restaurants decrease water usage without dampening dinner.
Mice exposed to a high concentration of asbestos-contaminated dust, have a higher level of genetic somatic mutations, compared with other regions where asbestos pollution levels are lower. This has been shown in a new study.
A Baylor University expert is available to journalists for interviews about how climate change in the desert southwest will decrease the likelihood of widespread and intense wildfires, such as the one in Arizona, over the next 50 years.
