Amphetamines reverse Parkinson's disease symptoms in mice

...ate brain processes that affect movement, emotion, pleasure and mood. Parkinson's disease stems from the degeneration of neurons in a brain region that controls movement. That degeneration, in turn, leads to a shortage of the chemical messenger dopamine. The finding that amphetamines can alter movement indep...

...umans transport the eggs on their fishing gear and pleasure boats. Professor Norman Yan of Ontario's York University has demonstrated that predation by the spiny water flea causes an average loss of three zooplankton species.
