Former Sen. Alan Simpson spoke to NPR's Steve Inskeep this morning and the conversation was wide-ranging and spirited, but one thing was crystal clear: Simpson, who served as a Republican senator from Wyoming, was not happy about the Congressional "horror show" that lead to Standard & Poor's downgrade of U.S. debt.

Soy pills for the hot flashes and bone loss menopausal women may endure seemed like a great idea – a cheap way of getting the benefit of estrogen without the risks.

But alas, a new study concludes they don't work.

In the past year, more than two dozen states have considered legislation that would prevent the use of Shariah, the Islamic code that guides Muslim beliefs and actions, in courtrooms.

Half-way through what was scheduled to be a 60 hour swim, 61-year-old Diana Nyad had to abandon what she called her "Xtreme Dream" — a 103 mile swim from Cuba to Florida.

"It's over. She lasted 29 hours in an heroic attempt," said Elaine Lafferty, one of Nyad's crew members, on Twitter.

On the same Twitter account, her team said that earlier in the evening Nyad was in the water, "surrounded by dolphins and a beautiful Caribbean sunset." But, they explained, a strong wind "blew her 15mph off course."
