That might seem like a colossal waste of time, but scientists are starting to harness some of that effort to solve vexing problems in biology.

<item><title>(Refeed) A Gene for Fish Order</title><description>British scientists have developed a genetic test for a disorder that causes people to emit an unusual body odor: The gene causes sufferers to smell like rotten fish. For those who have been ostracized—shunned by friends and unable to hold jobs because they are perceived as unhygienic—the test offers some solace. But one patient says the genetic discovery has not changed his life as much as he had hoped for.

	<item><title>(Refeed) Surveillance City </title><description>In this interview with The World's Marco Werman, NOVA Producer Miles O'Brien describes how surveillance footage played a key role in cracking the case of the Boston Marathon bombings. But as O'Brien discovered in the course of reporting the NOVA special "Manhunt—Boston Bombers," other cities, especially New York City, have surveillance camera networks that are far more advanced than Boston's hodgepodge system. O'Brien recounts just how powerful those systems are and what that may portend for privacy in the future.

  <item><title>Cornering the Higgs</title><description>On July 4, 2012, scientists at CERN used the word "discovery" to describe the results of experiments designed to prove the existence of the Higgs boson, a particle that gives mass to the universe. Host Marco Werman of PRI's The World gets a down-to-earth layman's analogy for what it means to say that a particle "gives mass," finds out why it's called the "God particle," and hears from a member of one of the teams that found the new particle, Jordan Nash of Imperial College London, on what this means for him personally and for physics.

  <item><title>(Refeed) Elements in the Ocean</title><description>There's a lot more to the oceans than salt and water. Many other ingredients make up the rich broth that sustains marine life and helps regulate the Earth's climate. But where do those ingredients come from? To answer that question, French geochemist Catherine Jeandel has collected seawater from all over the world and is examining it for elemental clues.

Jennifer Francis, a climatologist at Rutgers University in New Jersey, believes that may be the case. In fact, her research shows that Arctic warming may have contributed to many of the extreme weather events of the past few years. Sam Eaton reports from New Jersey.

<item><title>Surveillance City</title><description>In this interview with The World's Marco Werman, NOVA Producer Miles O'Brien describes how surveillance footage played a key role in cracking the case of the Boston Marathon bombings. But as O'Brien discovered in the course of reporting the NOVA special "Manhunt—Boston Bombers," other cities, especially New York City, have surveillance camera networks that are far more advanced than Boston's hodgepodge system. O'Brien recounts just how powerful those systems are and what that may portend for privacy in the future.

Foley is a marine archeologist at the Woods Hole Oceanographic Institution. He's taking a new approach to the field. Instead of just focusing on a handful of shipwrecks, he wants to take a broad look, finding and cataloging wrecks in the Mediterranean that date to a wide timeframe. In this podcast, he talks to us about his work.

Thirty years ago, a violent eruption ripped through the side of Mt. St. Helens in western Oregon. The blast killed 57 people and countless animals, and turned hundreds of miles of forest into barren wasteland. In this podcast, hear from ecologist Charlie Crisafulli on the slow recovery of the Mt. St. Helens ecosystem, and learn how the timing of the eruption actually spared some plant and animal life.

His observations of the night sky in the early 1600s confirmed a new model of the universe, where the Earth orbited the sun—not the other way around. But before he was studying the universe, Galileo was working on practical problems. And his early goals for the telescope weren't so scientific.

<item><title>Toward a Smart Electric Grid</title><description>On August 14, 2003, the biggest blackout in American history struck the Northeast U.S. and parts of Canada. 50 million people lost power, and the blackout showed how vulnerable and even outdated our electricity system is. To fix that problem, some energy experts think it's time to upgrade to a "smart grid," one that uses digital technology to regulate itself.

So how could that poodle in your backyard have come from a wolf? To find out, we spoke to Clive Wynne, who studies animal behavior at the University of Florida.

<item><title>NASA's Forgotten Tapes</title><description>In the mid 1960s, NASA launched the first of five lunar orbiters. Each one transmitted hundreds of images of the moon's surface back to Earth, which NASA recorded onto miles of analog tape. It was state of the art technology for the 1960s. But today, it's mostly forgotten. For the last 40 years, the tapes from the Lunar Orbiter missions have collected dust in a warehouse, and the computer drives that could read them have gone the way of the dinosaurs. In this podcast, we talked to Dennis Wingo, an engineer who's working to recover the images from the now-obsolete tapes.

Each one transmitted hundreds of images of the moon's surface back to Earth, which NASA recorded onto miles of analog tape. It was state of the art technology for the 1960s. But today, it's mostly forgotten. For the last 40 years, the tapes from the Lunar Orbiter missions have collected dust in a warehouse, and the computer drives that could read them have gone the way of the dinosaurs. In this podcast, we talked to Dennis Wingo, an engineer who's working to recover the images from the now-obsolete tapes.

The blast killed 57 people and countless animals, and turned hundreds of miles of forest into barren wasteland. In this podcast, hear from ecologist Charlie Crisafulli on the slow recovery of the Mt. St. Helens ecosystem, and learn how the timing of the eruption actually spared some plant and animal life.

But in 2006, that all changed. At a meeting in Prague, the International Astronomical Union adopted a new definition for planethood, leaving the solar system with only eight planets. But not everyone agrees with its decision. In this podcast, planetary scientist Alan Stern talks to us about Pluto's demotion, and why he thinks it should be back on list of planets.

It's what's underneath the surface of the islands&#8212;huge caves systems filled with water. They're called blue holes, and deep inside of them lie clues to past climate change, new species of invertebrates, even human remains from people who lived on the islands long before Columbus visited. In this podcast, hear from Kenny Broad, a researcher who led a diving expedition into blue holes last year.
