of skin on tips of their right index fingers. This coactivation boosts the number of neurons involved in processing tactile information coming from the area of stimulated skin. By this method, external stimulation to finger tips temporarily reorganiz...
Models show gene flow from crops threatens wild plants
...alley just southwest of Mexico City stands a small patch
of teosinte - a wild, weedy grass thought to be the ancient ancestor of corn. As a gentle breeze blows gene-carrying pollen from a nearby crop of maize to its wild relative, the genetic integrity and even survival of this ancient plant and others cou...
Brain links non-food images with eating -- But only when hungry, study suggests
... "Say a rabbit is hopping around its little grassy patch
and he's learned how to find clover," Gottfried explained. "So, if he sees a particular tree stump, or rocky slope, that predicts clover." As if nature knew we wouldn't just stop eating when we were full, it also evolved a "brake system" for the cond...

Genetic profile, not clinical appearance, to determine tumor treatment

Artificial prions created
