Mind Controls: Magnetic Relief For Depression

Anyone who remembers high-school physics knows that a fluctuating magnetic field can induce an electrical current. That's the principle behind transcranial magnetic stimulation (TMS), where an electromagnet is held over the head and pulsed rapidly. Depending on the frequency of the pulses, this can either enhance or… »4/11/11 5:20pm4/11/11 5:20pm

Radio-Style System of Communication Via Magnetic Waves Demonstrated in Deep Mines

After 13 miners were trapped in a coal mine in Sago, West Virginia, four years ago, rescuers didn't know where to look for survivors — they could have been anywhere between 11,000 and 13,000 feet from the entrance. Radio waves can't penetrate very far through rock, so there was no way to communicate with the miners. »8/10/10 1:00am8/10/10 1:00am
