Back in the early 1970s, a young woman at Radcliffe College faced a choice: Stay in school and get her degree, or drop out and become a legendary blues singer and guitarist. It's pretty clear Bonnie Raitt made the right choice.

Pope Benedict XVI has given his final blessing before he steps down from the papacy on Thursday.

Here's more from The Associated Press:

"Benedict told the crowd that God is calling him to dedicate himself 'even more to prayer and meditation,' which he will do in a secluded monastery being renovated for him on the grounds behind Vatican City's ancient walls.

John Kerry sets off Sunday on his first foreign trip as secretary of state, visiting Europe and the Middle East.

One dominant theme of the trip will be how to resolve the crisis in Syria, where an estimated 70,000 people have been killed over the past two years. Kerry is portraying his trip as a listening tour, and he expects to hear a lot about Syria.

He told reporters recently that he wants to talk with U.S. allies about how to persuade Bashar Assad to agree on peace talks that would end the Syrian leader's bloody rule in Syria.

Prehistoric humans didn't have toothbrushes. They didn't have floss or toothpaste, and they certainly didn't have Listerine. Yet somehow, their mouths were a lot healthier than ours are today.

"Hunter-gatherers had really good teeth," says Alan Cooper, director of the Australian Centre for Ancient DNA. "[But] as soon as you get to farming populations, you see this massive change. Huge amounts of gum disease. And cavities start cropping up."

A lot of journalism about China focuses on the country's rapid and stunning changes, but equally telling are the things that stay the same. I did my first story on China's re-education through labor camps back in 2001.

I met a former inmate named Liu Xiaobo for lunch in Beijing. Liu, soft-spoken and thoughtful, had written an article mourning those who had died in the 1989 Tiananmen crackdown. He had also called for democracy.

So, one day, police took him from his house and charged him with "slandering the Communist Party" and "disrupting social order."

"Electricity is the most likely out of all of the alternative fuels ... to be the next fuel for the consumer."

That's what Jonathan Strickland of the website HowStuffWorks tells NPR's Jacki Lyden.

But electric vehicles are not without their controversies or challenges. One of the biggest questions is how a transition from gasoline to electric fuel can actually take place.

To those who closely follow the voter ID wars, Hans von Spakovsky is a household name, one of the nation's leading crusaders against voter fraud, and also one of its more controversial. Days before the 2012 election, The New Yorker profiled him as "the man who has stoked fear about imposters at the poll."
