Researchers have taken a new look at an old, but seldom-used technique developed by the petroleum industry to recover oil, and learned more about why it works, how it could be improved, and how it might be able to make a comeback not only in oil recovery but also environmental cleanup. The technology, called "microbial enhanced oil recovery," was first developed decades ago, but oil drillers largely lost interest in it due to its cost, inconsistent results and a poor understanding of what...

13-year Cascadia Study Suggests Risk For Large Earthquake
2012-08-01 13:16:27

A comprehensive analysis of the Cascadia Subduction Zone off the Pacific Northwest coast confirms that the region has had numerous earthquakes over the past 10,000 years, and suggests that the southern Oregon coast may be most vulnerable based on recurrence frequency. Written by researchers at Oregon State University, and published online by the U.S. Geological Survey, the study concludes that there is a 40 percent chance of a major earthquake in the Coos Bay, Ore., region during the next...

Scientists have discovered two viruses that appear to infect the single-celled microalgae that reside in corals and are important for coral growth and health, and they say the viruses could play a role in the serious decline of coral ecosystems around the world. These viruses, including an RNA virus never before isolated from a coral, have been shown for the first time to clearly be associated with these microalgae called Symbiodinium. If it's proven that they are infecting those algae and...

Moderate Alcohol Consumption May Help Prevent Bone Loss

Drinking a moderate amount of alcohol as part of a healthy lifestyle may benefit women's bone health, lowering their risk of developing osteoporosis. A new study assessed the effects of alcohol withdrawal on bone turnover in postmenopausal women who drank one or two drinks per day several times a week. Researchers at Oregon State University measured a significant increase in blood markers of bone turnover in women after they stopped drinking for just two weeks. Bones are in a constant...

Researchers at Oregon State University have created a new computer technology to listen to multiple bird sounds at one time, to identify which species are present and how they may be changing as a result of habitat loss or climate change. The system, one of the first of its type, should provide an automated approach to ecological monitoring of bird species that is much more practical than a human sitting in the field, hours on end. “It´s difficult to hear and identify even...

An individual´s sense of right or wrong may change depending on their activities at the time — and they may not be aware of their own shifting moral integrity – according to a new study looking at why people make ethical or unethical decisions. Focusing on dual-occupation professionals, the researchers found that engineers had one perspective on ethical issues, yet when those same individuals were in management roles, their moral compass shifted. Likewise, medic/soldiers...

Stream Temperatures Don’t Parallel Warming Climate Trend
2012-05-03 03:33:31

A new analysis of streams in the western United States with long-term monitoring programs has found that despite a general increase in air temperatures over the past several decades, streams are not necessarily warming at the same rate. Several factors may influence the discrepancy, researchers say, including snowmelt, interaction with groundwater, flow and discharge rates, solar radiation, wind and humidity. But even after factoring out those elements, the scientists were surprised by the...

A task force that conducted one of the most comprehensive analyses of global “forage fish” populations issued its report this week, which strongly recommends implementing more conservative catch limits for these crucial prey species. The Lenfest Forage Fish Task Force calls for the harvest reduction of sardines, anchovies and other forage fish so that they can continue to serve as critical prey for larger species, including salmon, cod and tuna, as well as for dolphins, whales,...
