It's series we're creatively calling Unfolding Science.<p>(SOUNDBITE OF THEME SONG)<p>BLOCK: Today, Joe tells us about large biological molecules called proteins that have to fold and unfold properly to keep us alive.<p>JOE PALCA, BYLINE: When we talk about food, protein is a kind of nutrient you get in meat, fish or foul.

I'M Tess Vigeland. Let us contemplate the American teenage girl, perhaps the very first one. Apparently, there's been some scientific debate about who she is and whether she hails from the same gene sequence as what we think of as the first Americans, American Indians. And when I say gene sequence, we're not talking about Skinnies from Urban Outfitters.

But faith is also impelling Bryan Shaw to create software to detect eye cancer in children as soon after birth as possible.<p>The Shaws are Christians, and their faith is extremely important to them. When they were at their bleakest, "Bryan would pull out the Psalms and say, 'This is how King David suffered in the Psalms, and we're going through this," says Elizabeth.

We've always been told that magnets have two poles, north and south. But theory suggests there should be something called a magnetic monopole, a magnet that has either a north pole or a south pole but not both of them. So far no one has found this elusive magnetic monopole.<p>As part of his project, Joe's Big Idea, NPR's Joe Palca brings us the story of scientists at Amherst College in Massachusetts. They have created a synthetic magnetic monopole.

Almost. At 3:21 p.m. ET Wednesday, the Juno space probe will be 347 miles away from Earth, just above the southern tip of Africa.<p>(As an aside, at around 11:30 a.m. ET, it was more than 90,000 miles away.)<p>It's not that Juno got homesick — the return to Earth was a necessity. To send it on a direct path to Jupiter would have required a more powerful rocket than the United Launch Alliance Atlas V-551.
