Sorry to disappoint, but science writer Carl Zimmer says we're not going to bring back dinosaurs. But, he says, "science has developed to the point where we can actually talk seriously about possibly bringing back more recently extinct species."

It's called "de-extinction" — and it's Zimmer's cover story for National Geographic's April issue.

In Albuquerque, N.M., there's a restaurant called Tim's Place. It's named after Tim Harris, a young man with Down syndrome who started the business in 2010 with help from his dad, Keith.

Six days a week, Tim greets each customer at the door. He calls it the world's friendliest restaurant.

The day Tim's Place opened "felt awesome," Tim, 27, tells his father on a visit to StoryCorps. "I wanted to own a restaurant ever since I was a kid. That was my dream."

At a hearing in Washington on March 6, Attorney General Eric Holder admitted to senators why it has been hard to go after big bank executives:

"It does become difficult for us to prosecute them when we are hit with indications that if you do prosecute, if you do bring a criminal charge, it will have a negative impact on the national economy, perhaps even the world economy. And I think that is a function of the fact that some of these institutions have become too large."
