Gene-Altered Mouse May Provide New Insights To Parkinson's Disease, Substance Abuse And Schizophrenia
...her hand, the lack of dopamine inthe brain's motor areas

of the brain. The researchers were able to show for the first time that structures higher up in the brain's chain of command directly control the more abstract information, while the component bits are managed by lower brain centers. The research is ...
Changing Continental Runoff Patterns Could Change Ocean Circulation
...elow less salty water. If runoff stops, new salty areas
could form to produce new deep water formation sites. In today's oceans, deep water forms near the poles with cold water sinking and then traveling toward the equator, while warmer water travels poleward near the surface. Temperature, not salin...
