Spread of modern humans occurred later than previously thought?

States with higher levels of gun ownership have higher homicide rates
Firearms are used to kill two out of every three homicide victims in America. In the first nationally representative study to examine the relationship between survey measures of household firearm ownership and state level rates of homicide, researchers at the Harvard Injury Control Research Center found that homicide rates among children, and among women and men of all ages, are higher in states where more households have guns. The study appears in the February 2007 issue of Social Science and Medicine. more

Gene that makes people 'early to bed and early to rise' demystified
The recent discovery that a mutant "clock" gene made some people "early to bed and early to rise," a condition known as familial advanced sleep phase syndrome (FASPS), offered one of the first glimpses into the genetic basis of sleep in humans. Now, researchers report in the Jan. 12, 2007 issue of the journal Cell, published by Cell Press, new evidence that helps to explain just how their bodies' natural alarm clocks get set to such an early wake-up time. more
Clinical alert on drug-eluting stents and late thrombosis
The Society for Cardiovascular Angiography and Interventions (SCAI) today released a clinical alert advising physicians on practical steps for reducing the risk of a rare but serious complication associated with the use of drug-eluting stents. The document follows hearings held by the Food and Drug Administration's Circulatory Systems Device Panel regarding the use of these devices. The panel supported the continued use of these devices but also suggested more research to determine whether the devices contribute to an increased likelihood of heart attack and death in complex heart disease patients who receive these stents. more
