Sad news: John Kanzius, the Florida-based inventor whose cancer-curing machine we awarded a PopSci Invention Award last year, passed away last Wednesday. Kanzius was a true PopSci guy: A former radio engineer who, upon being diagnosed with leukemia, figured there had to be a better way to deal with it than his crippling chemo treatments. So he pulled out his wife’s pie pans and started tinkering, ultimately creating a machine that would have great success in animal trials using radio waves and carbon nanotubes to burn away cancer cells. He was even profiled on “60 Minutes.”

Dr. Steven Curley, a professor of surgical oncology at Houston’s M.D. Anderson Cancer Center, who’s worked with Kanzius since 2004, will continue researching the treatment.
