Canadians Healthier Than Americans - Live Science  ATLANTA (AP)—  Americans are 42 percent more likely than Canadians to have diabetes, 32 percent more likely to have high blood pressure, and 12 percent more likely to have arthritis, Harvard Medical School researchers found, in a survey in which American and Canadian adults were asked over the telephone about their health. The study comes less than a month after other researchers reported that middle-aged, white Americans are much sicker than their counterparts in England.     
What a Dozen Cloves of Garlic Will Do - Live Science  Studies on the benefits of this food or that supplement often contradict each other, and the message can change over time. One new study on the potential benefits of garlic shows just how complex things can get and how important dosage is. Shela Gorinstein of the Hebrew University and colleagues fed rats garlic doses that ranged from 500 milligrams to 1,000 per kilogram of body weight. Only the 500-milligram dose lowered cholesterol and affected blood clotting.    

Hurricanes to Unleash Dormant, Hidden Power - Live Science  Kerry Emanuel sparked a debate among his colleagues last year when he published a paper that linked global warming to the trend of increasingly stronger Atlantic Ocean hurricanes observed in recent decades. In a study to be published soon, the Massachusetts Institute of Technology climatologist will make another bold claim: The cycling of hurricane activity from high to low, which some scientists have attributed to a natural cycle in global weather patterns, is in fact caused by the rise and fall of pollution released by humans.  Furthermore, Emanuel, along with Michael Mann of Pennsylvania State University, contend that the microscopic aerosol particles, which reflect sunlight and cool the atmosphere, have been masking the effect of global warming on Atlantic Ocean hurricanes for several decades. Meanwhile, other new research by Purdue University scientists supports Emanuel’s original finding and extends it to the entire globe.
