  • Genes Might Explain Hispanics' Added Longevity

    Posted: 08/28/2016

    Genes Might Explain Hispanics' Added Longevity FRIDAY, Aug. 19, 2016 (HealthDay News) -- Hispanics might carry genetic advantages that allow them to age at a slower rate than other ethnic groups, a new study finds. DNA analysis using a newly developed genetic "clock" found that Hispanics age more slowly because they are more resistant to natural processes that interfere with cell repair and development as we grow older, said lead researcher Steve Horvath. He is a professor of human genetics at the David...

    Gallstones Linked to Higher Heart Disease Risk THURSDAY, Aug. 18, 2016 (HealthDay News) -- People who've ever suffered gallstones may have a slightly increased risk of developing heart disease down the road, a large new study suggests. In a group of more than one-quarter million U.S. adults, researchers found those with a history of gallstones were 17 percent more likely to develop heart disease over the next few decades. Gallstones and heart disease share some of the same risk factors -- such as obesit...
