You can legally drink and drive in the United States, but there's a limit. In every state, drivers can't get behind the wheel if their blood alcohol content is .08 or higher, but the National Transportation Safety Board wants the states to lower the legal limit to .05 or even lower. Now, that would bring the United States into agreement with much of the rest of the world.
If you're driving down the road someday and you come across a camper with a 50-foot periscope sticking up into the sky, you just might have crossed paths with Ira Leifer. His quirky vehicle is on a serious mission. It's sniffing the air for methane, a gas that contributes to global warming.
Leifer is an atmospheric scientist at the University of California, Santa Barbara. But you'll more often find him off campus, in a garage, next to a string of auto body shops near the airport.
For years, reports have suggested that Afghanistan is sitting on massive deposits of copper, gold, iron and rare earth minerals valued up to $3 trillion. This provides hope for a future economy that would not have to rely so heavily on foreign donations.
But with an uncertain political, regulatory and security environment, international investors are hesitant. And it could be many years before Afghanistan begins extracting its mineral wealth.
Six years ago, the FBI took on a challenge: To review what it called cold-case killings from the civil rights era. The investigation into 112 cases from the 1950s and 1960s is winding down, and civil rights activists are weighing the FBI's efforts.
The review comes with word this week of the death of a man who'd been named, by a newspaper investigation, as a possible suspect in one notorious case.
It's been a long slog already for the bipartisan immigration overhaul proposed by the Senate's Gang of Eight.
The legislation has been the target of more than 300 amendments during days of debate and votes by the Senate Judiciary Committee. But while the bill has largely held its own so far, its prospects for getting through Congress remain uncertain.
In Judiciary Committee Chairman Patrick Leahy's view, the immigration overhaul is "moving very well."
"It's moving a lot faster than people said it would," says Leahy, a Vermont Democrat.
When actress Geena Davis was watching children's shows with her daughter a few years ago, she became so troubled by the lack of female representation, she started a think tank on gender in the media. The Geena Davis Institute recently partnered with University of Southern California professors to conduct a study analyzing gender roles and jobs on screen.
The good news? Prime-time television's pretty decent at depicting women with careers.
Colin Broderick's first book, Orangutan, told the story of the 20 years — at least, as he could remember it — of being drunk, drug addicted and often desperate struggling to make his way as an Irish immigrant to New York.
Robert Langdon is back. The Harvard art professor in custom tweeds — and an ever-present Mickey Mouse watch — wakes up in a hospital after getting grazed in the head by a bullet, wondering how he ended up in Florence. He's got a sinister artifact sewn into his coat and just a few hours to keep the world from a grim biological catastrophe.
Ana Popovic's fiery technique on her Fender Telecaster has earned her an impressive nickname: "The Serbian Scorcher."
Popovic grew up playing the blues in Belgrade during the turbulent time of the fall of communism and the dissolution of Yugoslavia. Her furious fret work and singing brought her to the attention of blues fans, first in Europe and then the United States. She lives in Memphis today, and has just released her ninth album, Can You Stand the Heat.
