Atmospheric jet streams are fast-flowing currents of air found approximately 10 km above sea level in the extratropical regions of both hemispheres. Because these jets influence regional weather patterns, there is great interest in understanding the factors that control their path, their strength and variations in both.?Tue, 05 Jun 2012 07:52:52 EDThttp://www.sciencedaily.com/releases/2012/06/120605075201.htmMagnetic stimulation to improve visual perceptionhttp://www.sciencedaily.com/releases/2012/06/120605075159.htm Using transcranial magnetic stimulation (TMS), an international team has succeeded in enhancing the visual abilities of a group of healthy subjects.
