In this short, a family dog disappears into the woods...and the mystery of what happened to him raises a big question about what it means to be wild.

There’s a common problem faced by Alzheimer's and Dementia patients all over the world: lost in their memories, they sometimes get disoriented, and wander off. When this happens, they can end up far from home and frightened, or even hurt. So what are you supposed to do if your loved ...

We begin in the middle of a phone call with Lulu Miller, who tells us the story of a couple with a seemingly unsolvable problem. It's the 1970s, and Richard and Tucker are very much in love. They'd like to get married, but it's against the law. And that would have been the end of the story...except that Richard, worried about Tucker and frustrated that he couldn't legally provide for him, came up with a very unusual (but totally legal) solution.

Lulu says these moments, where one little switch can reframe reality, are a kind of duct tape for the ethereal sadness. It's a form of hope, where an imperfect workaround opens up a door and makes life a little bit better.

And that brings us to a man named Jim Eggers, who suffers from a problem that not only puts his life at risk--it jeopardizes the safety of everybody around him. Producer Pat Walters explains how Jim found a way to manage his anger with the help of a bird named Sadie. African Grey Parrot expert Irene Pepperberg helps us understand how this could work, and shares some insights from her work with a parrot named Alex.

Two stories about heart-stopping falls:

1. Falling Time: David Eagleman gets to the bottom of what goes on in our brains during those life or death moments when time seems to slow way down.

2. Falling in Love: Lulu Miller brings us the story of Sarita and Simon, who fell in...and then out...of love.

Lulu Miller talks to a nursing home in Düsseldorf, Germany that came up with a novel approach to caring for Alzheimer's and Dementia patients.

Yet another listener has sent in a youtube that makes us stop what we're doing and gather around ye olde computer screen to gaze upon its offerings. Darn you, Ross Bennett, for indulging our desire to procrastinate! You want to us to finish Season 5, don't you? Alas. This one's too good not to pass along.

Robert Krulwich's commencement speech at California Institute of Technology gets at the heart of what we do here at Radiolab. It's a treat to hear his passion. We enjoyed it. And we thought you might too.

This week, a piece from one of our favorite radio-makers, Jonathan Mitchell. 'City X' is a history of the modern shopping mall through perspectives of people living in a real, yet unnamed, city.

First, we asked you to tell us what song gets stuck in your head. Then, we asked you how you got it out. Finally, we made a podcast. Thank you to everyone who called in, shared their secret techniques, and sang without shame.

Jad presents a piece by one of his favorite producers: Ben Rubin. This audio portrait, called 'Open Outcry,' visits the trading floor of the New York Mercantile Exchange, with its hundreds of traders shouting unintelligible phonic abbreviations and numbers back and forth.

The World Science Festival and WNYC Radio present You and Your Irrational Brain, a live, outdoor event (rain or shine) Thursday, May 29th at Water Taxi Beach in Long Island City, Queens, NY.

Ever wonder how Jad and Robert met? They tell their tale on stage at Oberlin College, and talk about how they started tinkering around with tape to come up with the Radiolab you know today.

This just in: Robert Krulwich was selected as an Official Honoree of the 12th Annual Webby Awards, for the animated component to his NPR stories about carbon. Krulwich and his video team (animator Odd Todd, Aneal Mundra, and BPP Video Producer Win Rosenfeld) were honored in the Online Film and Video - Best Use of Animation/Motion Graphics category for their cartoon feature, "It's All About Carbon", which was a part of NPR's Climate Connections series. The videos have an unexpected level of quirk and insight. Check them out here.

In light of Jad's recent birthday, we thought we'd share this video. It's sort of like a video version of "Nancy Grows Up" from our Time episode.

For a disturbing, but thought-provoking video clip that investigates the brain-body connection, check out Jonah Lehrer's blog for an entry he calls "The Poetry of Decapitated Dogs." In our show "Where Am I?" we heard all sorts of stories about when the brain and body connection gets screwy... but we never thought to take it quite this far.

Here's the first installment of 'Music Lab.' A place on the blog where Jad gets to play some of his favorite music and tell you why he likes it. Take a listen.

Jad plays one of his favorite pieces of all time, 'IF' by Sherre DeLys.

Imagine that you're a composer. Imagine getting the commission to write a song that will allow family members to face the death of a loved one. David Lang had to do just that when a hospital in Garches, France, asked him to write music for their morgue, or 'Salle Des Departs.'

You've heard of the tortured artist. The tortured poet. Did you ever think about the tortured zoo director? It's tough work being the steward of animals while at the same time being their captor. David Hancocks, a former zoo director, tells us about the paradoxes he encounters in the zoo world and his dream for a future zoo.
