| 1. | Diesel Fungus | 00:00:00 | | 4/22/2009 | Scientists know that one day we'll run out of oil and other natural sources of energy. Beyond solar power and wind power and ethanol, what are some other potential alternative energy sources?

| 2. | Hills in the Ocean | 00:00:00 | | 4/22/2009 | In the Western Pacific around New Guinea, there's a watery hill almost two hundred and fifty feet high. This isn't a hill on the ocean floor, it's a hill in the ocean's surface itself. The slope is very gradual because the hill is hundreds of miles across, but it's definitely there.

| 3. | Ear-friendly Train Tunnels | 00:00:00 | | 4/22/2009 | The most famous tunnel is the thirty mile "Chunnel" between England and France. Thirty miles of air is a lot to push around, so engineers have come up with a clever solution. The Chunnel is actually two separate tunnels, connected by cross passages.

| 4. | Popping Ears on a Train | 00:00:00 | | 4/22/2009 | When a train enters a tunnel, it compresses the air in front of it like a piston. Unlike outside air, air in a tunnel can't be simply pushed aside—the tunnel walls are in the way.

| 5. | Bombed from Space | 00:00:00 | | 4/22/2009 | As a meteor passes into Earth's atmosphere it experiences tremendous air resistance on its front end, but very little on its back end. It is this imbalance of forces that rip it apart; for a large meteor, moving fast enough, hitting atmosphere can be just as destructive as hitting solid ground.
|
| 6. | Barnacle Goose or Goose Barnacle? | 00:00:00 | | 4/22/2009 | Barnacle geese leave Europe in spring and fly north to breed on rocky Arctic islands. Newly hatched young and their parents spend the long summer days feeding on plants in the tundra.
|
| 7. | Kin Recognition in Ground Squirrels | 00:00:00 | | 4/8/2009 | Scientists studying rodent species have found that odor is an important cue. Urine in rats and mice contains many chemical by-products produced by a set of genes know as the major histocompatibility complex.
|
| 8. | Tiger Extinctions | 00:00:00 | | 4/7/2009 | There are thirty-eight cat species in the world, but none of them command the respect and awe of the tiger. In Asian myths it is the king of beasts as well as a demon, but in the real world this dangerous predator has become the hunted.

| 9. | Ninety-eight Point-Magic Number or Medical Myth? | 00:00:00 | | 4/6/2009 | Hard exercise can raise the temperature as much as four or five degrees; so if you're running hard to make that doctor's appointment, don't be surprised if your temperature reads a little high.
|
| 10. | You Gotta Have Heart | 00:00:00 | | 4/2/2009 | The heart is a muscle the size of your fist that's located in the center of the chest behind the breast-bone, or sternum. We generally say the heart is on the left side of the chest because about two-thirds of its mass is to the left of the sternum.
