New Orleans commemorates 10-year Katrina anniversary

On Saturday, New Orleans residents commemorated the 10th anniversary of Hurricane Katrina, which killed more than 1,800 people and cost $151 billion in damage across the region. "We saved each other," Mayor Mitch Landrieu told dignitaries at a memorial for the unidentified and unclaimed dead. "New Orleans will be unbowed and unbroken." Residents and activists gathered for speeches and a parade in the city's Lower 9th Ward, where a levee broke. In Mississippi, also hit hard by Katrina, coastal church bells rang out to remember one of the deadliest storms in U.S. history.

Chris Christie said he wants to track immigrants like FedEx packages

Presidential hopeful and New Jersey Gov. Chris Christie (R) spoke to a crowd in Laconia, New Hampshire, on Saturday about the need to crack down on illegal immigration. He said as president, he'd use FedEx's package tracking strategies to monitor immigrants.

Smith's daughter, Samantha, serves as Christie's campaign spokeswoman.

Houston sheriff blames deputy's death on Black Lives Matter movement

Harris County Sheriff Ron Hickman linked the fatal shooting of his deputy in a Houston suburb to ongoing nationwide protests of police brutality. "We've heard black lives matter; all lives matter. Well, cops' lives matter too," Hickman said. "At any point where the rhetoric ramps up to the point where calculated cold-blooded assassination of police officers happen(s), this rhetoric has gotten out of control." Deputies arrested 30-year-old Shannon Miles on Saturday in the gas station shooting of Darren Goforth.

NASA begins year-long Mars mission simulation

Six NASA recruits locked themselves in a dome Friday to start a year-long simulation of a Mars mission, the longest such experiment yet. Based in Hawaii near a barren volcano, the team will live in isolation together with almost no privacy. They'll survive in cramped living quarters on basic foods and can only venture outside the dome by donning a spacesuit. NASA is looking to see what kinds of interpersonal conflicts could arise during a Mars trip, which would take significantly longer than missions to the International Space Station.

Miley Cyrus to host 2015 MTV Video Music Awards

Miley Cyrus will host MTV's 32nd Video Music Awards in Los Angeles on Sunday night.
