Faulty human eyesight can be corrected with glasses, but itÃs a different matter to fix vision problems that afflict instruments used by scientists who explore the microcosmos. Two Oregon scientists conducting research with National Science Foundation (NSF)-support, however, have found a way to do it. As with many problems in human eyesight, the culprit in the world of microscopes is the lens.
One of the hot new trends in management -- worker participation -- has been touted as a boon to employees because it allows them to play an active role in making decisions involving their jobs. But such management systems, which often involve workplace teams, may hurt relations among co-workers, a new study suggests.
First came drugs to break apart clots that can cause a stroke when they block an artery carrying blood to the brain. Now researchers are developing a new family of drugs called neuroprotectants designed to minimize the disabling damage to brain tissue that can occur downstream from the clot, caused by the loss of blood flow that characterizes these ischemic strokes.
A new three-minute screening test that detects one-sided motor paralysis allows paramedics and other first-responders to rapidly identify people experiencing a stroke, and may soon enable on-the-scene treatment with drugs that can limit the potentially extensive damage caused by these ìbrain attacks,î Los Angeles researchers reported here today at the American Heart AssociationÃs 22nd International Joint Conference on Stroke and Cerebral Circulation.
A bit of alcohol can protect against stroke, but even a little cigarette smoke carries a hidden stroke risk, researchers reported here today at the American Heart AssociationÃs 22nd International Joint Conference on Stroke and Cerebral Circulation. Light or occasional alcohol consumption lowered stroke risk by up to 62 percent compared to non-drinkers in a New York City study. But people who had at least five drinks daily tripled their stroke risk.
The ability to recognize symptoms and risk factors for stroke, the nationÃs third leading cause of death and leading cause of serious disability, appears to be woefully inadequate among the general public and people experiencing ìbrain attack,î Cincinnati researchers reported here today at the American Heart AssociationÃs 22nd International Joint Conference on Stroke and Cerebral Circulation.
Clot-dissolver tissue plasminogen activator (TPA) can reduce the disability of people who survive an ischemic stroke, one caused by a clot that blocks an artery carrying blood to the brain. But given the drugÃs cost of over $2,000 a dose, are the benefits worth the money? Yes, according to a new study.

Researchers at The University of Texas M. D. Anderson Cancer Center have shined a bold new light on the future treatment of childhood leukemia. Results of a study published in the Jan. 30 issue of the New England Journal of Medicine not only refute a 30-year-old dogma universally held by the medical community, but also open new doors to a better understanding of acute lymphoblastic leukemia (ALL), the most common form of childhood cancer. Using two sensitive assays, M. D. Anderson researchers found that up to thousands of leukemia cells may remain in a patient long after successful treatment.

"Millions of Americans -- including children with asthma and the elderly -- are suffering daily from dirty air," said Fran Du Melle, the Lung Association's Deputy Managing Director.
Small filamentous masses called Lewy bodies have long been observed in the neurons of people with Parkinson's disease. Many investigators consider the abnormal structures relatively unimportant in disease progression. Now, however, University of Pennsylvania Medical Center scientists have discovered that Lewy bodies may entrap life-sustaining cellular organelles in an important population of cerebellar cortex neurons called Purkinje cells, leading to their death with age.

ATHENS, Ga. -- The Southern Ocean -- that vast expanse of water that surrounds the frozen continent of Antarctica -- has been reluctant to give up it wealth of scientific secrets. But new information gathered from a voyage to the bottom of the world could have a major impact on how scientists view the role oceans play in the global carbon and nitrogen cycle. Dr. Deborah Bronk, a biological oceanographer from the University of Georgia, undertook a six-week voyage to the Southern Ocean and to Antarctica's Ross Sea.

Testing a new aircraft can be costly and risk. But a new scale-model, remote-piloted test plane developed at NC State University with funding from the U.S. Navy may help reduce those risks and costs by letting researchers identify potential problems before they occur in manned flights. The test plane, a 17.5 percent scale version of the U.S. Navy's newly updated F/A-18 E/F Super Hornet strike fighter, was developed by a team of NC State researchers led by Drs. Charles Hall and John Perkins.
