A team of researchers from SDSU has found silicone wristbands to be an effective way to measure children's exposure to secondhand smoke.

A new study by SF State University Assistant Professor of Health Education Lara Cushing and colleagues at the University of Southern California used satellite data to track flaring, an often underreported and potentially harmful oil and gas industry practice.

In recent years, calls to preserve greater swaths of the Earth's land- and seascapes have grown. In particular, numerous conservationists have called for the protection of half of the planet's surface, a bold initiative that would preserve much of the world's existing biodiversity and ecosystem function. However, the path to such a 'half-Earth' preservation model lies largely in uncharted territory, with many potential pitfalls along the way.

Each year, about 27 million tires end up in landfills, dumps and stockpiles, where they pose health and environmental hazards. These tires could get a second life as components of the roads they once traveled, but blends of ground tires and asphalt can be unstable. Now, researchers have identified polymer additives that increase the storage stability of asphalt rubber. They report their results in the ACS journal Energy & Fuels.

The Research Center for Gas Innovation is developing technology to separate CO2 and methane in oil and gas exploration and store it in offshore salt caverns.

All women exposed to high levels of DDT are at increased risk for breast cancer through age 54, but the timing of cancer risk depends on when they were first exposed, according to a new study published today in the Journal of the National Cancer Institute by the Public Health Institute's Child Health and Development Studies.
