New Therapy Could Preserve Vessel Function After Heart Attack
Scientists have identified the process that causes blood vessels to constrict during and after a heart attack. They've also demonstrated that delivering a vital molecule that is depleted during this process directly to those blood vessels can reverse damage and help restore blood flow. The medical researchers say these findings have the potential to improve outcomes for patients with acute coronary episodes related to ischemia, and to ameliorate the restriction of blood supply to the heart. New Gene Identified For Condition That Causes Blood Clots In Brain
Researchers have identified a new gene linked to cerebral venous thrombosis, a condition that causes blood clots in the veins of the brain that can lead to stroke. The condition is more common in young and middle-aged women. Salmon Survival, Cleaner Hydropower Focus Of ORNL Research
A new advanced turbine being tested at Wanapum Dam in Washington state produces nearly 5 percent more power, but before more are installed researchers at Oak Ridge National Laboratory are getting input from several thousand fish. Alaskan Storm Cracks Giant Iceberg To Pieces In Faraway Antarctica
A severe storm that occurred in the Gulf of Alaska in October 2005 generated an ocean swell that six days later broke apart a giant iceberg floating near the coast of Antarctica, more than 8,300 miles away. A team of scientists led by Professors Douglas MacAyeal at the University of Chicago and Emile Okal at Northwestern University present evidence connecting the two events in the October issue of the journal Geophysical Research Letters. Invasive Ants Territorial When Neighbors Are Not Kin
A study led by University of California, San Diego biologists shows that invasive Argentine ants appear to use genetic differences to distinguish friend from foe, a finding that helps to explain why these ants form enormous colonies in California. Rats With Migraines Provide Jefferson Scientists Insights To Improved
When Michael Oshinsky, Ph.D., gives his rats a headache, he has good reason.The animals are helping Dr. Oshinsky study how migraine treatments work. In recent experiments, the animals provided evidence showing that DHE, a standard drug currently used to treat acute migraine pain can also work against the onset of a phenomenon called "central sensitization,"or "allodynia,"which involves, as most migraine sufferers know, a heightened sensitivity to touch. Breakthrough Toward Industrial-scale Production Of Nanodevices
Scientists are reporting an important advance toward the long-sought goal of industrial-scale fabrication of nanowire-based devices like ultra-sensitive sensors, light emitting diodes, and transistors for inexpensive, high-performance electronics products. Ian's Shoelace Site
"How many possible ways are there to lace an average shoe?"The author presents nearly two dozen methods he considers "worthy of devoting the time required to create instructions"Includes illustrations, and information about shoelace knots, aiglet ("the plastic or metal sleeves at the ends of shoelaces") repair, and shoelace length formulas. Side Effects Of Cholesterol-lowering Drugs
In a report published in the online issue of Circulation: Journal of the American Heart Association, (May 24, 2005), researchers said the cholesterol-lowering drug rosuvastatin (Crestor) was more likely to be associated with muscle damage (myopathy) compared to atorvastatin (Lipitor), simvastatin (Zorcor) and pravastatin (Pravachol). Ancient Climate Change May Portend Toasty Future
Scientists, including Ken Caldeira of the Carnegie Institution's Department of Global Ecology, have found that the Earth's global warming, 55 million years ago, may have resulted from the climate's high sensitivity to a long-term release of carbon. This finding contradicts the position held by many climate-change skeptics that the Earth system is resilient to such emissions.
