Surprises in Your Genes

Tue, 20 Dec 2011 12:00:00 -0500

In order to develop from an embryo, animals as different as fruit flies and humans call on a nearly identical set of genes.

In Defense of Pluto

Tue, 13 Dec 2011 12:00:00 -0500

After Pluto was discovered in 1930, it enjoyed the title of planet for more than 75 years. 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. Podcast produced by David Levin.

Toward a Smart Electric Grid

Wed, 23 Feb 2011 11:00:00 -0500

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the Northeast U.S. and parts of Canada. 50 million people lost power, and the blackout showed how vulnerable and even outdated our electricity system is.

Ethics of Erasing Memory

Tue, 14 Dec 2010 17:00:00 -0500

If you could take a drug that could erase your memories, would you do it? It’s not such a hypothetical question—neuroscientists have identified a drug that can wipe out memory in rats. It’s not something that could be used on humans, but its existence raises a lot of big ethical issues. To sort those out, we talked to Art Caplan, director of the Center for Bioethics at the University of Pennsylvania. Produced by David Levin. NOVA is produced by WGBH in Boston.

The Origin of Dogs

Mon, 8 Nov 2010 17:00:00 -0500

New DNA evidence shows that dogs were probably domesticated from wolves in the Middle East about eight thousand years ago. But wolves are generally fierce animals that travel in packs, and they’re usually afraid of humans. That's pretty far off from the behavior of today's family pets. 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. Podcast produced by David Levin.

Music and Memory

Thu, 26 Aug 2010 17:00:00 -0500

Slowly, inevitably, Alzehimer's disease robs a person of their memories. Not just everyday memories--like where to find keys or a wallet--but more profound ones, like the names and faces of loved ones. Right now, there's no cure. But one pair of researchers thinks music might help mitigate the effects of the disease. Podcast produced by Rebecca Cheung. NOVA is produced by WGBH in Boston.

A Bolt From the Blue

Fri, 28 May 2010 13:00:00 -0500

Neurologist and author Oliver Sacks has come across plenty of odd stories while studying the human brain, but none are quite as mysterious as that of his colleague, Tony Cicoria.

NASA's Forgotten Tapes

Wed, 12 May 2010 17:00:00 -0500

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. Podcast produced by David Levin. NOVA is produced by WGBH in Boston.

Life in the Blast Zone

Mon, 3 May 2010 12:00:00 -0500

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.

The Deciding Factor

Mon, 26 Apr 2010 17:00:00 -0500

For more than 100 years, academic economists have treated the market almost like a force of nature--a vast invisible system that operates independently from human emotions. But on a day-to-day basis, emotion plays a big role in the choices we make. In this podcast, we talked to Jennifer Lerner, a social psychologist at Harvard University, about how our feelings affect our financial decisions. Podcast produced by David Levin.

Twenty Years of Hubble

Fri, 23 Apr 2010 17:00:00 -0500

On Saturday, April 24th, the Hubble Space Telescope will reach its 20th year in orbit. To mark the anniversary, we spoke to Ed Weiler, Chief Scientist for the Hubble mission from 1979 to 1998. He talked to us about the Hubble's early days--its conception, its first years in space, and its infamous optical problems, which blurred its view until a repair mission replaced faulty cameras in 1993.

Hubble's Legacy

Fri, 16 Apr 2010 17:00:00 -0500

On April 24th, NASA celebrates the Hubble Space Telescope's 20th year in orbit. Over the last two decades, it's sent back thousands of stunning images of deep space. For scientists, these pictures have allowed a deeper understanding of the universe. For the public, they've been a source of wonder and inspiration. With the Hubble's anniversary around the corner, we asked Neil deGrasse Tyson to give his take on the telescope's legacy. He's the director the Hayden Planetarium in New York, and is one of Hubble's biggest fans. Podcast produced by David Levin. NOVA is produced by WGBH in Boston.

Galileo and the Telescope

Tue, 6 Apr 2010 17:00:00 -0500

Galileo has been called the "father of modern science". 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. Podcast produced by David Levin.

The Origin of Dogs

Mon, 29 Mar 2010 10:00:00 -0500

New DNA evidence shows that dogs were probably domesticated from wolves in the Middle East about eight thousand years ago. But wolves are generally fierce animals that travel in packs, and they're usually afraid of humans. That's pretty far off from the behavior of today's family pets. 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. Podcast produced by David Levin.

Thu, 11 Mar 2010 16:00:00 -0500

NASA's twin rovers, Spirit and Opportunity, have been exploring the surface of Mars for more than six years. It's an impressive fact, considering they were only designed to last for three months. But despite this longevity, recent mechanical failures have brought the Spirit rover to a standstill.

The Littlest Planet

Fri, 5 Mar 2010 10:00:00 -0500

In 2006, the International Astronomical Union decided on new definition of a planet--and Pluto didn't make the grade. It was bumped down to "dwarf planet" status. But it's not alone. It's now one of five known dwarf planets in the solar system. One of them, called Ceres, may hold clues to how life formed on Earth. In this podcast, we talked to planetary scientist Mark Sykes about this tiny world. Podcast produced by David Levin. Original interview by Susan K. Lewis. NOVA is produced by WGBH in Boston.

In Defense of Pluto

Wed, 24 Feb 2010 17:00:00 -0500

After Pluto was discovered in 1930, it enjoyed the title of planet for more than 75 years. 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. Podcast produced by David Levin.

Diving Into Danger

Tue, 9 Feb 2010 11:00:00 -0500

Scientists are excited about the Bahamas, and it's not just the tropical vacations that have their interest. It's what's underneath the surface of the islands—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. Podcast produced by David Levin. Original interview by James Barrat.

Shaping Skulls

Wed, 27 Jan 2010 17:00:00 -0500

For thousands of years, people around the world have modified their bodies with tattoos and piercings. But some cultures, like the ancient Inca in Peru, took that practice beyond skin deep. They sometimes used ropes and boards to slowly change the shape of human skulls. It's a process called "cranial modification." In this podcast, bioarcheologist Valerie Andrushko explains.
