Researchers are gaining valuable insight into how Ebola uses glycoproteins to wreak its deadly havoc. Results from this study provide insight into the strategies that Ebola virus uses to evade detection and point to potential antiviral targets. The new findings may also have far-reaching benefits for fighting other illnesses.
Developing nations, including China and India, face an epidemic of heart disease and stroke that could devastate their economies, researchers report in today's Circulation: Journal of the American Heart Association.
Bacteria found in dental plaque near diseased gums can induce clumping of blood platelets, a University of Minnesota study has found. Such clumping is an early step in the formation of blood clots, the precipitating event in heart attacks. While previous reports have linked bacterial infections to the buildup of atherosclerotic plaque in coronary arteries, the researchers believe this to be the first evidence linking bacteria to the event that directly causes most heart attacks.
Which is the most important factor influencing student performance in mathematics: A good teacher? Innate intelligence? Home environment? Studying hard? They're all important, of course. But differences in how Asians and Americans answer this question help to explain the U.S. disadvantage in math and science achievement.
1) Screening for chlamydia is cost effective versus no screening and subsequent treatment of the disease. 2) Annals of Internal Medicine Launches New Series to help physicians lead the charge to redesign health care. 3) Treatment options, counseling, followup and survelliance skills need to be employed by physicians and other health care workers with individuals that have recently been exposed to HIV via sexual relations. 4) Alendronate, a bisphosphonate, has been shown to prevent bone loss in women without osteoporosis.

Older women are at greater risk for depression than men or younger women, yet often the condition goes unnoticed or untreated, according to the National Policy and Resource Center on Women and Aging at the Heller Graduate School, Brandeis University.
When politics and science clash, science -- and ultimately society -- are the losers. So says Dr. JoAnn Burkholder, a North Carolina State University aquatic ecologist whose pioneering research on the fish-killing toxic marine microorganism, Pfiesteria piscicida, was one of 1997's top science stories and also fodder for one of the year's most contentious public debates about the role science should play in shaping environmental policy.
A $3M NASA grant to the University of New Hampshire will fund an Earth Observing System Web-based System for Terrestrial Environmental Research, EOS-WEBSTER.

President Clinton's selection of Dr. Rita Colwell as the next Director of the National Science Foundation is an outstanding choice. Her record of accomplishment speaks for itself. She is an internationally -recognized researcher, an admired educator, and she has consistently stepped forward as a leader in science and technology policy. She is an ideal choice to lead NSF into the 21st Century.
I welcome the opportunity to help lead the President's science and technology team. This is an exciting and demanding time for science and engineering. America's science agenda has moved rapidly beyond narrow Cold War concerns. Scientists and engineers are now challenged to address a broad range of critical social, economic, environment and health needs.
The results of a study funded by the NIH to avoid rejection to platelet transfusion, found that leukocyte (white blood cell) reduction of platelet components by filtration significantly reduced the incidence of refractoriness.
Depending on how an attorney describes DNA evidence at a trial, jurors will believe the evidence is either irrefutable or unpersuasive, finds Dr. Jonathan J. Koehler, consultant for the defense in the O.J. Simpson criminal trial, and a professor of behavioral decision making at the University of Texas at Austin.
Most people think there's little they could learn from a fruit fly. But Dr. Trudy Mackay knows better. In her research laboratory at North Carolina State University, Mackay studies the genetic basis of complex traits in fruit flies, with the aim of applying that knowledge to better understanding human genetics

As the threat of a U.S. attack on Iraq looms, parents may want to add the evening news to the list of violent TV programs they don't want their children to see. But she says screening news broadcasts doesn't mean that parents should avoid discussing the topic of war with their children.
1) Hawaiian undersea volcano turns up the heat, 2) Most states' math and science performance is up, 3) Next timss comparisons look at 12th graders
Women have gone from the "have it all" culture of the 1970s to the "do it all" of today, but what they really need to embrace is the concept of "share it all," says a Vanderbilt Divinity School professor.
Scientists from some 14 institutions are braving the elements on the icy Great Lakes in an intensive field program underway this winter. Researchers on this Lake-Induced Convection Experiment, or Lake-ICE, are trying to better understand midwest meteorology and lake -effect winter storms.
