Stock prices suggest a 90-year gap At the current pace of research and development, global oil will run out 90 years before replacement technologies are ready, says a new University of California, Davis, study based on stock market expectations. The forecast was published online Monday (Nov. 8) in the journal Environmental Science & Technology. It is based on the theory that long-term investors are good predictors of whether and when new energy technologies will become commonplace. "Our...

Biopolymers are the more eco-friendly material, but farming and energy-intense chemical processing means they are dirtier to produce than petroleum-derived plastics, according to study in Environmental Science & Technology An analysis of plant and petroleum-derived plastics by University of Pittsburgh researchers suggests that biopolymers are not necessarily better for the environment than their petroleum-based relatives, according to a report in Environmental Science & Technology....

Driving a car increases global temperatures in the long run more than making the same long-distance journey by air according to a new study. However, in the short run travelling by air has a larger adverse climate impact because airplanes strongly affect short-lived warming processes at high altitudes. The study appears in ACS' Environmental Science & Technology, a semi-weekly journal. In the study, Jens Borken-Kleefeld and colleagues compare the impacts on global warming of different...

On the eve of the 2010-11 influenza flu season, scientists and engineers have identified the environmental conditions and surfaces that could enable a highly pathogenic (H5N1) bird flu virus to survive for prolonged periods of time "” at least two weeks and up to two months. Among them: The virus appears to thrive at cooler temperatures and low humidity. The study, which could lead to new strategies for preventing the flu virus from spreading, appears in ACS' Environmental Science &...

Traces of crude oil that linger on the shores of Alaska's Prince William Sound after the Exxon Valdez oil spill remain highly biodegradable, despite almost 20 years of weathering and decomposition, scientists are reporting in a new study. Their findings, which appear in ACS' semi-monthly journal Environmental Science & Technology, suggest a simple approach for further cleaning up remaining traces of the Exxon Valdez spill "” the largest in U.S. waters until the 2010 Deepwater...

Scientists are reporting discovery of the biological secrets that enable plants growing near the Chernobyl Nuclear Power Plant to adapt and flourish in highly radioactive soil "” legacy of the 1986 nuclear disaster in the Ukraine. Their study, which helps solve a long-standing mystery, appears in ACS' Environmental Science & Technology, a semi-monthly journal. Martin Hajduch and colleagues note that plants have an unexpected ability to adapt to an environment contaminated with...

Homes in low-income and affluent communities in California both had similarly high levels of endocrine disruptors, and the levels were higher in indoor air than outdoor air, according to a new study believed to be the first that paired indoor and outdoor air samples for such wide range (104) of these substances. The study appears in ACS' Environmental Science & Technology, a semi-monthly journal. Ruthann Rudel and colleagues note concern about the reproductive and other health effects of...

The United States could completely stop emissions of carbon dioxide from coal-fired electric power plants - a crucial step for controlling global warming - within 20 years by using technology that already exists or could be commercially available within a decade. That's the conclusion of an article published online today, along with a news article on the topic, in the American Chemical Society's semi-monthly journal Environmental Science & Technology (ES&T). Both are scheduled for the...

Using productive farmland to grow crops for food instead of fuel is more energy efficient, Michigan State University scientists concluded, after analyzing 17 years' worth of data to help settle the food versus fuel debate. "It's 36 percent more efficient to grow grain for food than for fuel," said Ilya Gelfand, an MSU postdoctoral researcher and lead author of the study. "The ideal is to grow corn for food, then leave half the leftover stalks and leaves on the field for soil conservation and...

Such burns release less carbon dioxide than wildfires, scientists find The use of prescribed burns to manage western forests may help the United States reduce its carbon footprint. Results of a new study find that such burns, often used by forest managers to reduce underbrush and protect bigger trees, release substantially less carbon dioxide emissions than wildfires of the same size. "It appears that prescribed burns can be an important piece of a climate change strategy," says Christine...
