Three new research studies from the University of Texas at Arlington have found harmful pathogenic bacteria in Texas groundwater near unconventional natural gas extraction sites.

A new study co-authored by WCS (Wildlife Conservation Society) addresses concerns over the many Arctic shorebird populations in precipitous decline. Evident from the study is that monitoring and protection of habitat where the birds breed, winter, and stopover is critical to their survival and to that of a global migration spectacle.

Volcanic eruptions always seize the attention of climate scientists, because the sulfate aerosols formed in the volcanic plumes may stay months to years in the stratosphere—the second layer of the Earth’s atmosphere—resulting in the increase of radiation reflection from the Sun back into space, and therefore cooling the Earth's lower atmosphere or troposphere in a long time period. It is traditionally believed that because of atmospheric circulation patterns, eruptions in the tropics could have an effect on the climate in both hemispheres while eruptions at mid or high latitudes only have impact over the hemisphere where they erupt.

Peace River Valley, in northeastern British Columbia, has become known in recent years as a place of hydraulic fracturing for natural gas – "fracking," as it's commonly called. What are the health impacts related to living near fracking sites where contaminants, including volatile organic compounds, are released? To try to answer that question, Élyse Caron-Beaudoin, a postdoctoral researcher at the Université de Montréal Public Health Research Institute, studied a group of pregnant women who live in the area. Her results were published this week in Environment International.

The war over the Arctic National Wildlife Refuge (ANWR) — one of the most contentious and enduring environmental fights in U.S. history — is once again heating up. 

Most of the 150 million tons of plastics produced around the world every year end up in landfills, the oceans and elsewhere. Less than 9 percent of plastics are recycled in the United States, rising to about 30 percent in Europe.

A series of synthetic chemicals widely used in household products, food packaging and clothing have a significant effect on the development of frogs, even at low doses, according to a Purdue University study.

Per/polyfluoroalkyl substances (PFASs) are man-made chemicals used to make products stain resistant, waterproof and nonstick, and are present in foams used to fight fires. A U.S. Centers for Disease Control and Prevention (CDC) study from 2007 showed that some PFASs were present in 98 percent of blood samples collected from American adults and children for the National Health and Nutrition Examination Survey. According to the CDC, scientific studies on the impact of PFASs on human health are inconclusive.

Despite report after report linking air pollution to deterioration of the lungs, heart and brain, Professor Robert Phalen believes the air is “too clean” for children.

After all, everybody needs a bit of immune-system-boosting dirt in their lungs.

“Modern air is a little too clean for optimum health,” he told the American Association for the Advancement of Science (AAAS), one of the world’s largest scientific societies, in 2012.

Some impacts of global warming – such as sea level rise and coastal flooding – are already locked in and unavoidable, according to a major research project. 

Individuals who have A, B, or AB blood types have an elevated risk of having a heart attack during periods of significant air pollution, compared to those with the O blood type, according to new research from the Intermountain Medical Center Heart Institute and Brigham Young University.

The new study is unique in that it links increased risk of heart attack associated with small particulate pollution to increased risk of heart attack for people with certain blood types who have coronary artery disease.
