Radiolab wants something from you. Your questions.

The Radiolab team is looking to build a cabinet of curiosities. A clearing house, if you will, of questions. Your questions.

See, we already know what nags at us. Krulwich is all torn up about free will. Does it exist? Jad's become a grease-monkey at this point, who just wants to open the hood of anything to figure out how it works—cities, brains, aging cells, chaos. Lynn Levy's got a nagging question about a dolphin. Pat Walter's all brooding about the possibility of redemption. Tim Howard wonders where the cookie truck is parked today.

But what about you? What's irking you? Is there some question about how the world works. Not broad ideas for a show topic, but a specific question. That weird thing you've always wondered about. What's the difference between a feeling and an emotion? Why does caffeine make some people sleepy? Does time pass more slowly in different places, or at different speeds?

We here at Radiolab are here at your service; we'll cull through the questions, and take some of the best (the most itchy and pokey) ones to scientists, and present the answers on the blog.

What kind of things are we looking for?

We don’t know exactly. Whatever little thing seems to keep itchin’ at ya.

For instance, I’ve got a question about Alzheimer's disease. Could knowing the name of it—“Alzheimer's," if that word is locked in the safety of your early childhood memories— change the experience of having it? I’ll explain more in a future post, if and when I can get the question answered. But what we’re really interested in is your question.

So keep your ears pricked for the moment you hear yourself thinking, “Wait. How does that work?” And then jot it down. And then get it to us by posting it right here, in the comments section of this post.
