Childhood vaccination for the rubella virus may have also almost entirely eliminated an inflammatory eye disease from the US-born population, according to a new study. Currently, children commonly receive two doses of the vaccine by the time they are six years old. As a result of the vaccination program, the majority of U.S. rubella cases now occur in foreign-born individuals.

"We've never seen anything quite like it," says solar physicist Lika Guhathakurta from NASA headquarters. Guhathakurta watched in amazement as Saku Tsuneta of Japan played a movie of sunspot 10926 breaking through the turbulent surface of the sun. Before their very eyes an object as big as a planet materialized, and no one was prepared for the form it took. "It looks like a prehistoric trilobite," said Marc De Rosa, a scientist from Lockheed Martin's Solar and Astrophysics Laboratory in Palo Alto, Calif. "To me it seemed more like cellular mitosis in which duplicated chromosomes self-assemble into two daughter cells," countered Guhathakurta.

The Global Initiative for Chronic Obstructive Lung Disease has released new standards for the diagnosis, management and prevention of chronic obstructive pulmonary disease. The latest recommendations emphasize the importance of proper diagnosis, assessment of the disease's severity, and the need for a better understanding of co-morbidities to improve treatment of disease.

Scientistsare reporting the first simple and inexpensive method for building the large-scale networks of single-walled carbon nanotubes needed for using these microscopic wisps in a future generation of faster, smaller, and more powerful computers and portable electronic devices. They point out that no assembly method has solved all of the key problems involved in fabrication of large networks.

Modern conservation techniques have brought us the resurgence of American bald eagles, sustainable forest harvests and the rescue of prized lobster fisheries. So how can modern conservation strategies also have wrought such failures, from the catastrophic loss of Guatemalan forests to the economy-crippling Klamath River salmon kill in 2006? Scientists argue that while many basic conservation strategies are sound, their use is often flawed. The strategies are applied too generally, they say, as an inflexible, regulatory "blueprint" that foolishly ignores local customs, economics and politics.
