Effect Partners chief executive Michael Martin told of dodging a tornado in the United States only to find that lessons learned served him well during the recent global financial meltdown.
"I couldn't control what was happening to me, but I could control my reaction to it," Martin said of both scenarios. "Stay positive, show strong leadership, create a safe space, and know it will ultimately pass."
California Cars Initiative founder Felix Kramer preached about the benefits of running in bare feet, while orthopedic surgeon Kevin Stone told of breakthroughs in using animal tissue to rebuild battered knees stronger than they started.

Frederick Balagadde, a TED Fellow from Uganda who works at Lawrence Livermore National Laboratory in California, described his mission to build "microfluid" technology into an inexpensive iPhone-sized device for diagnosing HIV/AIDS.

"Plants have rampant, promiscuous and really quite interesting and curious sex," Drori assured an amused audience.
