with a sharp increase in insulin production. But when fat is present in addition to sugar, the GPR40 receptor causes even greater insulin output. Frequent overstimulation of the beta cells may be tied to persistently elevated insulin levels, hastenin...

up along the western coast of Africa acting as a natural barrier, and has prevented most warm water organisms from the Indian Ocean from making it in to the Atlantic for the last 2 million years. But when the world warmed about 150,000 years ago, go...

that wash, tsunami-like over the land. The trick, of course, is to find places where surge-caused layers of coastal sedimentation are consistently preserved and then to identify distinguishing details in the hurricane-caused layers. One place where s...

Pitt professor's article considers nature as a service provider
... is that three miles of wetlands will reduce storm surges
by one foot, and that an acre of wetlands provides roughly $20,000 worth of services. But that same acre would sell for only $500. The gap between market value and social value is hugeif everything in the grocery store was free, we'd walk out with it...

Scientists crack rhino horn riddle

caused by large hurricanes. They examined data from the TOPEX/Poseidon satellite, taken from four selected sites around Louisiana from 1992-2002. Using an innovative data processing technique, called "retracking," they were able to remove signal er...
New study to test statin-Parkinson's link
... if there is a link with statins, we could see big surges
