The findings suggest that using ecstasy may increase the risk of developing Parkinsonism--a condition similar to Parkinson's disease--later in life. http://sciam.rsc03.net/servlet/cc?lJpDVVZEKIIHkILkFJhQDgLmE0EX ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ** RANDOM MOVEMENTS HELP HUMANS BALANCE With some practice, it's not that hard to balance a baseball bat on the end of your finger. But try to poise a pen or a short stick, and the task becomes rather difficult. That's because a smaller object moves more quickly--at speeds that approach the time required to carry out corrective motions. New research suggests that random movements induced by the nervous system can help keep a stick balanced on a fingertip. http://sciam.rsc03.net/servlet/cc?lJpDVVZEKIIHkILkFJhQDgLmE0EA - Not a registered subscriber yet?
