Prayers and church bells in New Orleans marked the 10th anniversary of Hurricane Katrina, one of the deadliest natural disasters in U.S. history.

Mayor Mitch Landrieu, speaking to assembled dignitaries at a memorial to the unclaimed and unidentified among the estimated 1,800 who died in the storm, said the city had to rely on itself to get through the tragedy.

"We saved each other," Landrieu said. "New Orleans will be unbowed and unbroken."

NBC's former chief health editor, Dr. Nancy Snyderman, has shared her experience of being quarantined in her New Jersey home last year after reporting on Ebola.

Police in Bangkok says they have arrested a suspect that they think was involved in the deadly shrine bombing earlier this month that killed 20 people and wounded more than 120 others.

A foreigner was taken into custody today, Gen. Somyot Poompanmoung, the head of Thailand's national police force, told reporters.

He said authorities had also "seized a lot of evidence, including bomb-making materials." Somyot added that it was too early to say for sure that the suspect was involved in the Aug. 17 bombing of the Erawan shrine in central Bangkok.

A trio of journalists from Al-Jazeera English has been found guilty and sentenced to three years in prison after their re-trial in an Egyptian courtroom on terrorism-related charges.

The well-established soundscape at Burning Man is an audio layer cake of dubstep and techno. More than 60,000 people will gather in the Nevada desert next week for the annual arts festival — and many of them will spend their nights at post-apocalyptic raves, spinning fiery hula hoops and passing ChapStick around the dance floor.

"Eat, sleep, rave, repeat. Eat, sleep, rave, repeat," was the refrain of one song played all over the playa last year.

Mornings are made by routine. The alarm that warbles at the usual hour, the smell of coffee, the sound of familiar voices.

Those of us who work the morning shift grow to appreciate the intimacy we have with those who tune in. People wake to our voices. We come into their kitchens. They hear us as they shower, shave and brush their teeth. People like to tell us, "I wake up with you," and I still laugh to hear that.
