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

  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

  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...

Computer scientists in the field of artificial intelligence have made an important advance that blends computer vision, machine learning and automated planning, and created a new system that may improve everything from factory efficiency to airport operation or nursing care. And it's based on watching the Oregon State University Beavers play football. The idea is for a computer to observe a complex operation, learn how to do it, and then optimize those operations or accomplish other related...

A recent study suggests that parasites in fish, including threatened species of Oregon coho salmon, may have more profound impacts on fish health than has been assumed, and could be one of the key mechanisms by which habitat and land use changes cause salmon mortality. It's not just the presence or absence of parasites that is important, the research found, but their numbers that can build up over years or decades and ultimately cause major impacts. The study will be published soon in the...
