In the United States there are 19 million new sexually transmitted disease (STD) cases diagnosed each year, including 900,000 reported cases of chlamydia, 330,000 reported cases of gonorrhea, and 55,400 estimated new HIV infections per year.

Notifying sexual partners of their potential exposure to an STD has been a mainstay of disease prevention and control since the 1930s. Recent evidence-based reviews concluded that partner notification is effective for identifying those at risk for STDs and HIV infection.

In the world of "cut and thrust," humans try to bank money to obtain financial security, and often form cooperatives to reduce risks and increase gains.

Canada continues to export asbestos to developing countries, despite limiting its use in Canada, write Dr. Amir Attaran, David Boyd and Dr. Matthew Stanbrook http://www.cmaj.ca/press/pg871.pdf on behalf of the CMAJ editorial team. Canada is in fact opposed to placing chrysotile, the main asbestos fibre used today, under the Rotterdam Convention's notification and consent process, despite chrysotile being deemed a human carcinogen.

ST. PAUL, Minn. – A new study shows that people who are physically active before suffering a stroke may have less severe problems as a result and recover better compared to those who did not exercise before having a stroke. The research is published in the October 21, 2008, print issue of Neurology®, the medical journal of the American Academy of Neurology.

The typical Western diet — fried foods, salty snacks and meat — accounts for about 30 percent of heart attack risk across the world, according to a study of dietary patterns in 52 countries reported in Circulation: Journal of the American Heart Association.

Researchers identified three dietary patterns in the world:

What do presidential candidate Barack Obama and Snapple Iced Tea have in common? Patricia Turner, professor of African American and African studies at the University of California, Davis, will answer that question in a presentation at the American Folklore Society in Louisville, Ky., on Thursday, Oct. 23.

CHAMPAIGN, Ill. — Immigrants whittle into a broad earnings gap with American-born workers only about half as fast as long-accepted estimates suggest, according to new research by a University of Illinois economist.

Darren Lubotsky says immigrants' typically low starting wages grow just 10 to 15 percent faster than native-born workers over their first 20 years in the U.S., well short of the 26 percent catch-up rate in widely used, census-based projections.

Despite thousands of years of research, astronomers know next to nothing about how the universe is structured. One strong and accepted theory is that large galaxies are clustered together on structures similar to giant soap bubbles, with tinier galaxies sprinkled on the surface of this "soapy" layer.

MADISON, WI, OCTOBER 20, 2008 -- The widespread use of pesticides across the United States has been in practice for decades, with little knowledge of the long-term effects on the nation's groundwater.

The results of a new study show that samples taken from over 300 wells across the US have not retained a high concentration of pesticide contamination. The news is a result of a decadal long study to assess the extent of the impact of contaminants on the nation's water supply.

A new study led by North Carolina State University's Dr. Scott Fitzpatrick is the first to show physical evidence that the people who colonized the Caribbean from South America brought with them heirloom drug paraphernalia that had been passed down from generation to generation as the colonists traveled through the islands.
