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.

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.

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.

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
