...ng important in receiving signals, but this result suggests
we should be looking at the sending side of the neuron," Hosford said. Hosford has already shown that drugs that inhibit GABAb receptors control seizures in the mice genetically prone to petit mal epilepsy. The new information will allow the researc...

Duke Geologists Explore Alternative Way To Measure Ice Age Sea Bottom Temperatures
DURHAM, N.C. --A new study suggests
that differing calcium-magnesium ratios in the shells of tiny North Atlantic Ocean marine fossils may finally provide scientists with an unambiguous way to reconstruct how bottom sea water temperatures have changed during and between past ice ages. I...

...ncreased with the amount of fat in the diet. "It suggests
that people who eat high-fat diets will actually get themost benefit from rosemary," Milner says. "For typical Americans,who eat more fat than they should, rosemary may be particularly important." However, the type of fat consumed was important: Die...

that replacingthe many stately mahoganies felled by loggers in tropical forests will notbe a simple matter. While mature mahogany trees normally grow in thick woods, she has foundno evidence that new mahogany seedlings will successfully grow in the ...

Siblicide In Nature: Study Of Galapagos Seabird Finds Death Can Ensure Species Survival
...student working in Andersons Galapagos laboratory, suggests
that masked booby parents even stand over their chicks to give the attacking bird more room to maneuver. The masked boobies nest, flatter than the blue-footed species, may also make the ejectors job easier. In contrast, blue-footed booby parents squa...
