New genes present drug targets for managing cholesterol and glucose levels

ANN ARBOR, Mich.---Scientists have identified 12 new genes that are somewhat strange bedfellows: Some link gallstones and blood cholesterol levels, others link melatonin and sleep patterns to small increases in glucose levels and larger jumps in the risk of diabetes. While these associations a...

Nano-tetherball biosensor precisely detects glucose

WEST LAFAYETTE, Ind. - Researchers have created a precise biosensor for detecting blood glucose and potentially many other biological molecules by using hollow structures called single-wall carbon nanotubes anchored to gold-coated "nanocubes." The device resembles a tiny cube-shaped tetherball....

U of M researchers invent 'flashy' new process to turn soy oil, glucose into hydrogen

Anyone who's overheated vegetable oil or sweet syrup knows that neither oil nor sugar evaporates--oil smokes and turns brown, sugar turns black, and both leave a nasty film of carbon on the cookware. Now, a University of Minnesota team has invented a "reactive flash volatilization process" that hea...

Scientists at Galileo Pharmaceuticals confirm inflammatory response linked to glucose levels

A team of scientists has discovered three molecules –?from a search of 58,000 compounds –?that appear to inhibit a key perpetrator of Alzheimer's disease.
