Bystanders who witness a cardiac arrest should dial 9-1-1 and then perform mouth-to-mouth ventilations and chest compressions -- the two major components of cardiopulmonary resuscitation (CPR) -- according to the American Heart Association in a statement on CPR published in its journal Circulation (Sept. 16).
The realization that atomic gas clusters could serve as part of a sort of ìlight bulbî that emits extreme ultraviolet (EUV) light when laser-heated has inspired a recently patented invention at Sandia National Laboratories. This light source enables research development of EUV lithography to pattern faster, more memory-dense microchips.
The American Lung Association thanks President Clinton for taking a big step forward to protect children by not endorsing the "global" tobacco settlement that proved woefully inadequate in addressing this nation's tobacco-related health problems. The President is right in signaling that Minnesota Attorney General Hubert H. Humphrey III should be allowed to put the tobacco industry on trial in January and that Congress should not allow the tobacco industry to dictate the timing of any legislative action.
Fish are an important global resource, yet scientists do not know how to predict how many fish will be produced in a given year.

The beauty of the Internet is also a beast. The Internet is a global network of networks -- mostly private, and often competing among themselves. While the diffuse structure of the Internet is one of its strengths, the competitive environment has made collaboration on operational and engineering requirements difficult, and has made research on the metrics of the Internet virtually impossible.
The earliest existing mound complex built by humans in the new world has been identified in Louisiana by a team of archaeologists and researchers from around the United States. Details of the discovery appear in tomorrowÃs (Sept. 19) issue of the journal Science. The complex of 11 mounds was built between 5,000 and 5,400 years ago and predates other known existent mound complexes by 1,900 years.

Results from the first two years of a four-year study on skillful mediation will be presented at the American Association for Marriage and Family Therapy conference Sept. 18-21 in Atlanta. "The crux of this research is to define what is skillful mediation," according to Margaret Herrman, a senior associate at the University of Georgia Vinson Institute of Government. "You can have mediation that's close to therapy and you can have mediation that's close to lawyering. Both styles can be highly successful, but is it mediation? We want to identify skillful practices that are common throughout mediation styles."
Thanks to clean-up and pollution prevention efforts, San Diego Bay is cleaner and attracting more marine life. Among the increasing population are borer worms that dine on the wooden pilings and fenders that support many of the piers along the Bay. One solution may be a new design created at UC San Diego and approved by the San Diego Unified Port District : pilings are made from molded hollow tubes of advanced composite materials including glass fiber and vinyl ester resin.
The University of Texas-Houston has been awarded $2.5 million by the National Institute of Arthritis and Musculoskeletal and Skin Diseases to establish a Specialized Center of Research (SCOR) in scleroderma, a chronic, often fatal connective tissue disease. Headquartered in the UT-Houston Medical School division of rheumatology and clinical immuno-genetics, the center will conduct a wide range of investigations into the disease for which there is no known effective treatment or means of prevention.
Why some patients with kidney diseases respond well to certain medications and others do not has continued to stump physicians. With no means to test the medications besides trial and error, finding the right treatment is often a frustrating experience for physicians and their patients.

"Unemployment has become less relevant to inflation," says economist Gary Shoesmith, director of the Center for Economic Studies at Wake Forest University's Babcock Graduate School of Management. "Unemployment has now been below 6 percent for three years, but inflation has continued to ease downward, plainly opposite the pattern seen in the business cycles of the 1960s, '70s and '80s. The old business cycle has changed."
"You shouldn't wear lipstick when you're drinking a glass of champagne." That unique reporting style of Joe Palca, science correspondent for National Public Radio, has earned him the top chemistry reporting award from the world's largest scientific society.
Cystic fibrosis, the most common hereditary disease in the United States, is caused by the malfunction of an ion channel that is critical for maintaining the secretions of salt and water that protect the lungs. New research suggests a novel way in which this ion channel may function, thus challenging a commonly held "corked/uncorked" theory. The finding, published in Thursday's issue of the journal Nature, paves the way for a more refined research effort to find a cure or improve treatment for cystic fibrosis.
Athens, GA-- What's occurring at the "micro-level" of a therapy session is the subject of research by a professor at the University of Georgia College of Family and Consumer Sciences. He uses discourse analysis -- a process that breaks down a conversation into the finest of detail.
Athens, GA--A program developed by a College of Family and Consumer Sciences professor at the University of Georgia allows counseling clients to "turn the tables" on their therapists. "By directly obtaining feedback from clients about their experience of the therapy events and the therapist's actions, the therapist and supervisor are better able to focus their energy on helping the client," said Bill Quinn, a FACS professor.
Athens, GA--A program that combines first-time juvenile offenders, their parents and siblings with counselors has shown a 21 percent decrease in recidivism rates when compared with juveniles who didn't complete the program.

A minority-owned small business in New York and the Department of Energy's Oak Ridge National Laboratory are uniting to harness the power of knowledge through the innovative Community of the Future Initiative.
Albany Medical College researchers have for the first time provided data that shows that the major predictor of resistance to AIDS drugs is whether the amount of virus in a patient's body has been reduced to nondetectable limits. The analysis showed that among the patients who received just Indinavir, those who were able to reduce the amount of virus in them to less than detectable levels had "significantly lower risks of emergence of resistance" to the drug. When combination therapy was used, such as a combined treatment of Indinavir, AZT, and 3TC, patients had significantly longer times to resistance compared to monotherapy patients even after adjusting statistically for the increased antiviral effect of the additional drugs.
A research team at Boston University School of Medicine has discovered that a synthetic compound significantly limits brain damage when administered after a stroke. Their finding, published September 16 in the Proceedings of the National Academy of Sciences, could lead to the development of drugs to treat stroke and traumatic brain or spinal cord injury. These new drugs could also slow the progression of ParkinsonÃs disease and ALS, more commonly known as ìLou GehrigÃs disease.î
