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,...

A team of scientists has documented for the first time that animals can and do consume Archaea — a type of single-celled microorganism thought to be among the most abundant life forms on Earth. Archaea that consume the greenhouse gas methane were in turn eaten by worms living at deep-sea cold seeps off Costa Rica and the West Coast of the United States. Archaea perform many key ecosystem services including being involved with nitrogen cycling, and they are known to be the main...

Nanotube Tech Leading To Faster, Lower-cost Medical Diagnostics
2012-03-11 07:11:06

Researchers at Oregon State University have tapped into the extraordinary power of carbon “nanotubes” to increase the speed of biological sensors, a technology that might one day allow a doctor to routinely perform lab tests in minutes, speeding diagnosis and treatment while reducing costs. The new findings have almost tripled the speed of prototype nano-biosensors, and should find applications not only in medicine but in toxicology, environmental monitoring, new drug...

Endangered Antarctic Blue Whales Show Surprising Genetic Diversity
2012-03-09 03:30:09

More than 99 percent of Antarctic blue whales were killed by commercial whalers during the 20th century, but the first circumpolar genetic study of these critically endangered whales has found a surprisingly high level of diversity among the surviving population of some 2,200 individuals. That, says lead author Angela Sremba of Oregon State University, may bode well for their future recovery. Results of the study have just been published in the open-access journal, PLoS ONE. As part of...

Magic Weight Loss Pill Doesn’t Exist, Most Supplements Are Ineffective.
2012-03-07 13:52:15

After studying weight loss supplements and the body of evidence surrounding them, an Oregon State University researcher has found that no single product is proven 100 percent effective. In fact, many can be harmful to your health. Melinda Manore posted her study online in the International Journal of Sport Nutrition and Exercise Metabolism. Manore is the professor of nutrition and exercise sciences at Oregon State University, and is a member of the Science Board for the President´s...

Oregon State University´s first-ever Natural Resources Leadership Academy (NRLA) is scheduled for June, and it will deliver diverse instruction in the areas of conflict management, communication, sustainable natural resources and leadership. Corvallis, OR (PRWEB) February 24, 2012 Oregon State University, recognized nationally for its work in natural resources, is extending the expertise of its faculty this summer to professionals and graduate students in the field for a pair of...

A Battle Of The Vampires, 20 Million Years Ago
2012-02-04 04:33:28

They are tiny, ugly, disease-carrying little blood-suckers that most people have never seen or heard of, but a new discovery in a one-of-a-kind fossil shows that “bat flies” have been doing their noxious business with bats for at least 20 million years. For bats, that´s a long time to deal with a parasite doing its best vampire impression. Maybe it is nature´s revenge on the vampire bat, an aggressive blood consumer in its own right that will feed on anything from...

The average price for a 30-second advertising spot in the 2012 Super Bowl on Feb. 5 is a staggering $3.5 million and a new study suggests that, for advertisers, it may not really matter if the New England Patriots or the New York Giants win. But for the sake of companies forking out big bucks on the ads, it had better be a close and exciting game. The study by an Oregon State University researcher, which is being published in the spring issue of the Journal of Advertising, found that...

New research suggests that major growth in the travel, leisure and tourism industry in the coming century may be possible as more people begin to define recreation as a learning and educational opportunity — a way to explore new ideas and cultures, art, science and history. Some of this is already happening, although the expansion of tourism in much of the 20th century was often focused on amusement parks and tropical resorts — not that there´s anything wrong with them....
