A wonderful story from the LA Times about radio engineer John Kanzius, who may have discovered a way to target and kill cancer cells with radio waves. It's too early to say, but it could turn out to be a cure for all types of cancer:
Kanzius did not have a medical background, not even a bachelor's degree, but he knew radios. He had built and fixed them since he was a child, collecting transmitters, transceivers, antennas and amplifiers, earning an amateur radio operator license. Kanzius knew how to send radio wave signals around the world. If he could transmit them into cancer cells, he wondered, could he then direct the radio waves to destroy tumors, while leaving healthy cells intact?
It seems the answer might be 'yes.' Read the whole thing.
By the way, I've written about Kanzius before.
