Hearts Don't Gain If Blood Sugar Is Leashed
from the Chicago Tribune (Registration Required)
Two large studies involving more than 21,000 people found that those with Type 2 diabetes experienced no reduction in their risk of heart attacks and strokes and no reduction in their death rates if they rigorously controlled their blood-sugar levels.
The results bolster findings reported in February, when one of the studies, by the National Institutes of Health, ended prematurely. At that time, researchers made the surprising announcement that study participants who were rigorously controlling their blood sugar actually had a higher death rate than those whose blood sugar control was less stringent.
Now the federal researchers are publishing detailed data from that study. Researchers in the second study, from Australia and involving participants from 20 countries, are also publishing their results on blood sugar and cardiovascular disease.

PODCAST & VIDEO: Engineering Around Extreme Events
Extreme events, such as super floods and hurricanes, are becoming more common, so civil engineers are trying to adapt civil infrastructure such as bridges to these unpredictable and sometimes devastating meteorological events. Engineer Ana Barros discusses how engineering can prepare us for extreme weather events, but also how changing climate and population conditions can affect the ability of infrastructure to hold up over time.
