Nearly a year ago, former CIA technical assistant Edward Snowden stepped forward to say he was responsible for one of the most explosive leaks in history. The National Security Agency was exposed, and Andy Yen, a Harvard PhD candidate, was appalled.
"I posted on Facebook, 'Hey, I don't really like the fact the government is wiretapping us. What's happening in America?'"
After Yen posed the question, dozens started chiming in, equally as startled and determined to change the conversation. As Snowden had said last summer:
Johns Hopkins scientists have developed a reliable method to turn the clock back on blood cells, restoring them to a primitive stem cell state from which they can then develop into any other type of cell in the body.
