Some 12,000 Americans die every year in traffic crashes caused by speeding, according to government statistics. Officials have tried many strategies to get drivers to slow down. And now they might have found something that works, after researchers placed a GPS device inside cars that gives drivers an incentive not to speed.

Traffic safety experts have tried using big flashing signs to tell you how fast you're going. (The psychological subtext: Drivers are rational, and they will slow down if they know how fast they're going.)

As Americans watched their nest eggs sink during the Great Recession, many wondered whether they would ever be able to retire. Come this fall, millions of workers who invest in 401(k)s will learn their plans are probably worth even less than they thought.

"Fees take away from the accumulated savings of your lifetime," says Mary Beth Franklin, a contributing editor at InvestmentNews.

Mexicans go to the polls July 1 to choose their next president, and polls show that voters seem inclined to embrace the past. The center-left Institutional Revolutionary Party, or PRI, which ruled the country for more than seven decades before being ousted 12 years ago, holds a solid lead.

But Mexico's young are making their voices heard: Some fear a return of authoritarian rule; others simply want jobs.

Making Noise

There's an overwhelming amount of electronic music available on the web, and every week a new crop emerges. Countless remixes, edits and mashups make their way through the web every day. It's a lot to sift through; everyone could use a little help.

The music I'm obsessed with this week is an EP called Trap S--- by a producer named UZ.

We don't know much about UZ — I spoke with him over email, but his alias was about all the guy would reveal about himself. The name of his EP is a profane piece of slang that the producer traces back to hip-hop.
