A widely-used mortality risk chart indicates that, of 1000 men McCain's age who are former smokers, over 200 will die in the next five years, roughly the time from now until his presidential term would end.

Why is it that the origins of many serious diseases remain a mystery?  In considering that question, a scientist at the university of California, San Diego School of Medicine has come up with a unified molecular view of the indivisible unit of life, the cell, which may provide an answer.

New research suggests that cigarettes' power may not be in nicotine itself but in how it enhances other experiences while smoking.

A new study conducted at a large university finds more than 25 percent of those surveyed reported symptoms of tanning dependence, including symptoms similar to alcohol and drug-addicted individuals. Suggestively, the study also found those with a tanning dependence tend to be more likely to be thin and smoke cigarettes than others.

With close monitoring and a few standard precautions, nearly all children with known or suspected vaccine allergies can be safely immunized, according to a team of vaccine safety experts led by the Johns Hopkins Children's Center. The scientists offer pediatricians a step-by-step tool for quickly identifying children with allergic reactions to vaccines, and a much-needed guide, they say, to safely immunize those who are allergic.

A team of scientists is studying the complex ocean upwelling process by mimicking nature -- pumping cold, nutrient-rich water from deep within the Pacific Ocean and releasing it into surface waters near Hawaii that lack the nitrogen and phosphorous necessary to support high biological production.

One of the few studies to look at the effects of religious participation on the mental health of minorities suggests that for some of them, religion may actually be contributing to adolescent depression. Previous research has shown that teens who are active in religious services are depressed less often because it provides these adolescents with social support and a sense of belonging.

Astronomers have taken the closest look ever at the giant black hole in the center of the Milky Way. By combining telescopes in Hawaii, Arizona, and California, they detected structure at a tiny angular scale of 37 micro-arcseconds -- the equivalent of a baseball seen on the surface of the moon, 240,000 miles distant. These observations are among the highest resolution ever done in astronomy.
