Gene regulation, not just genes, is what sets humans apart
...ps would simply not be able to digest like starchy root
crops. The researchers found dramatic differences in the regulatory regions of their genes for breaking down more complex carbohydrates. It may be that parts of the human metabolism are cranked up to digest carbs down to simpler sugars. Regulatory ...

extract blunts a significant percent of the blood pressure rise that occurs in rats placed on a high salt diet. Kudzu has also been shown to reduce blood glucose, insulin and leptin in this animal model of insulin resistance (a precursor to type 2 di...
Disabling a sensory organ prompts female mice to act like male mice

causes of sexually dimorphic behaviors -- those that differ between the sexes. The new findings promise to redirect that quest. "From a developmental standpoint, the finding is very satisfactory," said Catherine Dulac, an HHMI investigator at Harva...
