Concussions are not kids stuff.

Even a pretty small knock to a child's head can lead to problems for months afterward, a new study finds.

Researchers charted the progress of more than 250 kids admitted to two hospitals for either mild traumatic brain injuries or broken bones in an arm or leg.

The kids who had brain injuries — especially ones that led to unconsciousness or visible changes on MRI scans — were more likely than the others to have headaches, tiredness and trouble thinking a year after being seen at the hospitals.

Two British men have been arrested and charged with stealing Michael Jackson's entire music catalog. Wired estimates the collection is worth around $253 million. That's what Sony Music paid for the catalog following the King of Pop's death.

The two men allegedly hacked into Sony's internal music sharing system and stole the catalog, which also included a wealth of previously unreleased material.

The last time Morning Edition spoke with K'naan, he had just gone back to his native Somalia for the first time in 20 years to highlight the effects of the famine there.

Ernie Lopez calls it his "rebirth." After spending nearly nine years in prison for the sexual assault of a 6-month old girl, a top Texas court threw out the conviction. And on Friday, the 41-year-old Lopez walked out of the detention center in Amarillo, Texas, where family and friends were waiting.

In Britain, there's a long waiting list of British animal lovers hoping to take in aging police horses. Once retired, the horses aren't supposed to be ridden again.

Unless, it seems, you're Rebekah Brooks, the former tabloid editor and chief executive of Rupert Murdoch's News International, or David Cameron, the man who would become Britain's prime minister.

The ongoing inquiry into the relationship between the police and news media has uncovered a new scandal: Scotland Yard appears to have loaned Brooks a police horse back in 2008.

Ever since The Rising in 2002 — and arguably since 1984's Born in the U.S.A. — Bruce Springsteen releases have functioned as State of the Union addresses as much as pop LPs. Wrecking Ball does, too, beginning with its Occupy-era lead single "We Take Care of Our Own," an anthemic bit of wishful thinking which, like "Born in the U.S.A.," seems easy to misinterpret by 180 degrees if you don't pay attention to the verses between the chorus.

Sushi seems like the perfect modern food: Light, healthful and available at seemingly every supermarket in the nation. But is it sustainable?

That's the question behind "The Story of Sushi," a new video that's been pulling a lot of clicks in the past week. Maybe that's because its adorable format, with tiny, handcrafted figures used to tell the tale, stands in stark contrast to its depressing message: Most of the sushi we snarf up is harvested using unsustainable methods.

Robert Staake, the cover artist for the New Yorker's March 12 cover took a story that's an oldie but goodie — Mitt Romney strapping the kennel containing Seamus the family dog atop the family car during a vacation road trip — and gave it a new spin with Rick Santorum filling in for the dog.

Attorney General Eric Holder spoke in Chicago on Monday on the legal rationales for targeting and killing Americans suspected of terrorism overseas. Carrie Johnson talks to Melissa Block.

It was more than 30 years before Egyptian President Hosni Mubarak lost his grip on power, though many of his people had long suffered under his oppressive regime.

It took less than a week for "a newly minted ultra-conservative Islamist member" of the post-Mubarak parliament in Egypt to be forced to resign because he lied about getting a nose job.
