The uprisings of the Arab Spring unleashed a new political force in the region — Salafis. These ultra-conservative Muslims aspire to a society ruled entirely by a rigid form of Islamic law. Their models are the salaf, or ancestors, referring to the earliest Muslims who lived during the lifetime of the Prophet Muhammad.

With recreational marijuana now legal in Colorado, small-scale pot shops will open up soon in places like Denver and Boulder. But that's not the only business that could get a boost: Large-scale commercial farmers may also be in line to benefit.

In California in the early 1980s, a cracked tooth sent Mike Williams to the dentist's office.

When Williams asked to see the tooth, the dentist said he had a mirror but that there was no camera or anything to show people the insides of their mouths. So, Williams invented one: the first intraoral camera.

In 1962, a grisly double murder on a deserted stretch of desert rocked a small community outside Phoenix.

A young couple had been shot to death in a case that stumped Maricopa County investigators. Then, something happened that should have cracked it wide open: A man named Ernest Valenzuela confessed to the crime. But police didn't pursue the lead, just one misstep in an investigation and eventual trial that were rife with irregularities.
