Facebook will ask its nearly 1 billion users to vote up or down on changes to its privacy policy.

According to a statement released by the social network, the company also put changes up for a vote in 2009. Voting begins today and goes through June 8.

"If more than 30 percent of all active registered users vote, the results will be binding," Facebook said. "If turnout is less than 30 percent, the vote will be advisory."

In 2003, in a song called "Earthbound," singer Rodney Crowell name-checked a writer he admires a lot: Mary Karr, who has written searing memoirs, including the best-seller The Liars' Club, as well as several books of poetry.

A Florida judge this afternoon revoked George Zimmernan's bond and ordered that the man who killed teenager Trayvon Martin surrender himself to authorities within 48 hours, the Orlando Sentinel writes.

Since the Greek debt crisis began nearly three years ago, more than $90 billion has left the country.

It's tomato time here in the mid-Atlantic – the critical moment when those of us eager to pull fat, bright fruit off our own backyard vines in a couple months are scurrying to get tender little plants in the ground.

So, New York City Mayor Michael Bloomberg (I) wants to ban nearly all sales of big, sugary drinks.

This comes after his earlier campaigns to stamp out smoking and trans fats.

It might seem counterintuitive that Amazon is doing a deal with New Jersey to build two distribution centers in exchange for collecting sales tax on purchases made in the Garden State starting July 1, 2013.

After all, the free lunch enjoyed by many consumers as they shop tax-free online is one of the huge draws, right?

The first-edition Book of Mormon brought faithful from around the country to a book store in Mesa, Ariz.

As the AP describes it, the book is one of 5,000 printed "after Joseph Smith found the gold plates that he translated into the Book of Mormon, which members of the faith consider to be scripture alongside the Bible."

IRA FLATOW, HOST:

This is SCIENCE FRIDAY. I'm Ira Flatow. For the rest of the hour, a look at an extraordinary life and a heartbreaking loss.
