A new study links even small reductions in fine particle air pollution to increased life expectancy. Researchers who compared data from 545 counties across the U.S., including many in California, found that a drop in fine particulate matter , known as PM2.5, between 2000 and 2007 corresponded with an average rise in life expectancy of 0.35 of a year. The study, led by researchers at the Harvard School of Public Health, is described as the largest to date to find public health benefits from ongoing reductions in U.S. air pollution levels.

Life expectancy is up in the United States. We know this because the headlines have been trumpeting the news floating around all week. So maybe it’s time for a closer look at what factors affect life expectancy -- and what you can do about it. The National Vital Statistics Reports from the Centers for Disease Control and Prevention points to these causes of death (no surprises if you've been keeping up on health news). Heart disease is the No. 1 cause (616,067) followed by cancer (562,875)

JOHANNESBURG, South Africa - In scattered villages on steep green hillsides, many who killed their neighbors in Rwanda's genocide 20 years ago now live side by side with relatives of the dead. Speech that creates ethnic divisions has been outlawed. Local tribunals called gacaca courts have allowed many offenders to be released from prison in return for confessions and expressions of remorse. And a generation of young people who grew up after the mass killings embody the hope of a new breed of Rwandans who identify not by ethnicity but by nationality.

BEIJING - Life expectancy is 5.5 years lower in northern China than in the south because of heavy air pollution, a study examining 20 years of data concludes. The research -- published Monday in the Proceedings of the National Academy of Sciences by four economists in China, the United States and Israel - examined air quality readings collected in 90 Chinese cities from 1981 to 2000, and compared them with mortality data collected from 145 locations from 1991 to 2000. Other studies have established strong correlations between air pollution and poor health and attempted to quantify the resulting loss of life in China.

The gap in life expectancy between black and white Americans is smaller than it has ever been, thanks largely to a decline in the number of deaths resulting from heart disease and HIV infection, a new analysis has found. That's the good news. The bad news is that the gap is still large: A black baby boy born today can expect to live 5.4 fewer years, on average, than his white counterpart, and a black baby girl will die 3.7 years earlier, on average, than her white counterpart. What's more, the narrowing of the gap between 2003 and 2008 is due in part to a troubling development among whites: They are more likely than in the past to die from overdoses of powerful prescription medications like OxyContin and Vicodin, along with other unintentional poisonings.

Life expectancy has risen in the United States over the last 25 years, but it's not rising as fast as it once was. And, compared with other developed nations, U.S. life expectancy doesn't measure up. In a report released Tuesday by the National Research Council , experts describe U.S. life expectancy as a "poor performance" compared with many other countries given the fact that the U.S. spends far more on healthcare than any other nation....
