On the morning of September 11, 2001, I was attending a research seminar in Boston when my cell phone rang. I looked at the caller ID and saw that it was a friend in Manhattan. Not wanting to disturb the seminar, I blocked the call and returned my attention to the presentation on bone marrow stem cells. A few minutes later, the same friend in Manhattan called again. I was poised to ignore the call but then saw that others in the room were receiving messages. A researcher near me had his phone to his ear. “A plane hit the World Trade Center,” he announced. I answered my call. In a trembling voice, my friend said, “I can't believe it. I saw one plane crash into the Twin Towers. And I just saw a second one.”
