Energy doesn't grow on trees. That is why scientists are hard at work trying to find alternative sources of fuel. On Aug. 23, Sony announced its green-battery prototype, which is made out of a vegetable-based plastic and is powered by converting sugar into electricity. "We need to always be thinking green," says Derek Lovley, a UMass-Amherst microbiologist who does his part by researching mud-microbe batteries. Other sources tapped into...
Researchers analyzed medical information on 9,439 mother-child pairs who received health care through Kaiser Permanente in the Pacific Northwest and Hawaii. All women gave birth between 1995 and 2000, and none had pre-existing diabetes. The women were screened for hyperglycemia, or high blood sugar, and gestational diabetes; their children were measured for weight between the ages of 5 and 7 - what researchers call the adiposity-rebound period, during which excessive weight gain usually predicts adult obesity. Regardless of factors like race or ethnicity, birth weight and maternal weight gain or age, researchers found that the risk...
Women whose blood-sugar tests indicated gestational diabetes were 89% more likely than other women to have overweight children, and 82% more likely to have obese kids. Women whose blood-sugar readings were at the upper end of normal (122 mg/dl to 140 mg/dl) were still 22% more likely to have overweight children than women at the low end of normal (with blood-sugar levels between 43 mg/dl and 94 mg/dl), and 28% more likely to bear children who become obese. "Even in what's considered normal, in the highest quartile there was an elevation in risk," says Dr. Teresa...
...Pima Indian population, have shown a link between a mother's diabetes and obesity in her children. Hillier's study is the first, however, to suggest that treatment of the disease eliminates risk. In her analysis, Hillier found that children born to women with the highest levels of blood sugar were no likelier than other kids to become heavy if their mothers had been treated for diabetes during pregnancy...
...risk through what's referred to as metabolic imprinting. The idea is that outside of other genetic and environmental risk factors for obesity, children appear to become metabolically imprinted, or pre-programmed, for obesity by being overfed in the womb - a direct result of the mother's high blood sugar. "As we have more people with diabetes and gestational diabetes during pregnancy I think the importance of additional risk factors for obesity increases," says Hillier. "And if there is an alteration going on to program the child for obesity I think that starts a vicious cycle for obesity...
