Deep inside your intestines, there's a complex microbial ecosystem, which scientists say contains nearly a thousand species of bacteria.
A lot of recent research has shown that the community of gut microbes acts almost like another organ in your body — they're that crucial. They exert a pronounced effect on the nutrients and energy that get pulled out of food. And the bacteria are thought to play a big role in a slew of health conditions, including obesity and diabetes.

Last week, Matthew VanDyke, a freelance journalist and travel writer from Baltimore, went from solitary confinement in one of Moammar Gadhafi's most notorios prisons to one of Tripoli's most luxurious hotels.
VanDyke acknowledges that in early March, shortly after the uprising against Gadhafi began, he arrived in Libya in order to help the rebels.
"I was here to do whatever I could to help the revolution and I'll leave it at that," said VanDyke, who is now a guest at the Corinthia Hotel in the Libyan capital.
