ALS is incurable -- it’s a progressive attack on nerve cells that control voluntary movements--like breathing. We meet two men diagnosed with ALS: Ed Rapp, and Peter Warlick, who are raising awareness and millions of dollars for ‘Answer ALS,’ an unorthodox way to crowdsource research. And we talk to the research director, Dr. Jeffrey Rothstein, about how the Answer ALS approach mimics research on cancer, by applying stem cell technology.
