Too Much Stress Can Lead To Higher Mortality Rates
2011-10-21 03:35:06

[ Watch the Video ] A new study concludes that men who experience persistently moderate or high levels of stressful life events over a number of years have a 50 percent higher mortality rate. In general, the researchers found only a few protective factors against these higher levels of stress — people who self-reported that they had good health tended to live longer and married men also fared better. Moderate drinkers also lived longer than non-drinkers. “Being a...

“Albedo Effect” In Forests Can Cause Added Warming, Bonus Cooling
2011-10-20 06:10:28

Wildfire, insect outbreaks and hurricanes destroy huge amounts of forest every year and increase the amount of carbon dioxide entering the atmosphere, but scientists are now learning more about another force that can significantly affect their climate impact. Researchers conclude in a new study that the albedo effect, which controls the amount of energy reflected back into space, is important in the climatic significance of several types of major forest disturbances. In some cases...

Severe Drought, Other Changes Can Cause Permanent Ecosystem Disruption
2011-10-14 04:31:21

An eight-year study has concluded that increasingly frequent and severe drought, dropping water tables and dried-up springs have pushed some aquatic desert ecosystems into “catastrophic regime change,” from which many species will not recover. The findings, just published in the journal Freshwater Biology, raise concerns that climate change, over-pumping of aquifers for urban water use, and land management may permanently affect which species can survive. The research was...

Scientists Find Possible Trigger For Volcanic 'Super-eruptions'
2011-10-13 03:35:17

The "super-eruption" of a major volcanic system occurs about every 100,000 years and is considered one of the most catastrophic natural events on Earth, yet scientists have long been unsure about what triggers these violent explosions. However, a new model presented this week by researchers at Oregon State University points to a combination of temperature influence and the geometrical configuration of the magma chamber as a potential cause for these super-eruptions. Results of the...

New Program To Expand, Enhance Use Of LIDAR Sensing Technology
2011-10-12 03:03:43

Researchers at Oregon State University have developed a new system that will enable highway construction engineers in the field to immediately analyze soil movements caused by active landslides and erosion and use the powerful tool of LIDAR to better assess and deal with them. The advance, being outlined this week at the annual meeting of the Geological Society of America, is just one of the latest innovations with this laser technology, the use of which has mushroomed in recent years in...

New research has found that if you want some of the many health benefits associated with eating broccoli or other cruciferous vegetables, you need to eat the real thing — a key phytochemical in these vegetables is poorly absorbed and of far less value if taken as a supplement. The study, published by scientists in the Linus Pauling Institute at Oregon State University, is one of the first of its type to determine whether some of the healthy compounds found in cruciferous vegetables...

Image 1 - Microwave Ovens Key To Energy Production From Wasted Heat
2011-09-20 10:46:11

  More than 60 percent of the energy produced by cars, machines, and industry around the world is lost as waste heat — an age-old problem - but researchers have found a new way to make “thermoelectric” materials for use in technology that could potentially save vast amounts of energy. And it´s based on a device found everywhere from kitchens to dorm rooms: a microwave oven. Chemists at Oregon State University have discovered that simple microwave energy...

Researchers at Oregon State University have shown for the first time that loss of biodiversity may be contributing to a fungal infection that is killing amphibians around the world, and provides more evidence for why biodiversity is important to many ecosystems. The findings, being published this week in Proceedings of the National Academy of Sciences, used laboratory studies of amphibians to show that increased species richness decreased both the prevalence and severity of infection...

Wolves Could Help Recovery Of Canada Lynx
2011-08-31 05:39:58

  As wolf populations grow in parts of the West, most of the focus has been on their value in aiding broader ecosystem recovery — but a new study from Oregon State University also points out that they could play an important role in helping to save other threatened species. In research published August 30 in Wildlife Society Bulletin, scientists suggest that a key factor in the Canada lynx being listed as threatened under the Endangered Species Act is the major decline of...

Daphnia magna
2011-08-29 03:38:59

  Oregon State University (OSU) researchers have discovered a breed of freshwater zooplankton that they say can help combat a fungus that has been devastating amphibian populations around the world. According to the International Business Times, this particular species of zooplankton is known as Daphnia magna, a variety of aquatic flea from the genus Daphnia. They say that these organisms "could provide a desperately needed tool for biological control of the deadly fungus whose...
