Warming Climate May Cause Arctic Tundra To Burn:
Research from ancient sediment cores indicates that a warming climate could make the world's arctic tundra far more susceptible to fires than previously thought. The findings are important given the potential for tundra fires to release organic carbon -- which could add significantly to the amount of greenhouse gases already blamed for global warming.

Most Physicians Sleep Fewer Hours Than Needed For Peak Performance, Report Says:
In a new survey, physicians report they are not getting the sleep they need to function at their best and current work schedules may contribute to their inadequate sleep.

Results further indicated that, when compared to the general population, physicians reported more caffeine use but better overall health.
