CAN HUMANS SENSE GEOMAGNETIC STORMS? New research published by neuroscientists at Caltech shows that sudden changes in Earth's magnetic field affect human brainwaves--specifically, depressing alpha waves associated with wakeful relaxation. This raises the possibility that humans can sense geomagnetic storms. Learn more about the link between human biology and space weather on today's edition of Spaceweather.com
