Extremophiles in Kamchatka: Kamchatka: The Explorer Impulse (Clip)

Running Time:
00:05:16

This clip introduces the 2006 expedition to remote Kamchatka, Russia. Twenty scientists arrive via helicopter to study the unique microbiology and geochemistry of the hot springs of the Uzon Caldera. Microorganisms that can survive the scalding temperatures and acidity in the springs are called extremophiles, and understanding these organisms helps answer questions about the origin and evolution of life on earth.

NOAA's Okeanos Explorer: Forecast Seamount Hydrothermal Vents (Clip)

Running Time:
00:01:01

The remotely operated vehicle (ROV) Jason II measured temperatures as high as 200 degrees Celsius (392 degrees Fahrenheit) at these hydrothermal vents atop the Forecast Seamount in the Mariana Arc of the Pacific Ocean. Hydrothermal vents spew sulfur and other chemicals that support bacteria which use these chemicals to sustain life in a process called chemosynthesis. Snails and shrimp have colonized the site and are grazing on the chemosynthetic bacteria. Jason's suction sampler is used to collect some of these animals for analysis in the lab on board the ship.

Return to Mars: Happy Birthday, Opportunity (Webcast)

Running Time:
00:47:21

On December 11, 2005, Opportunity, one of the twin rovers exploring Mars, celebrated its first Martian birthday. Opportunity had been on the red planet 687 Earth days, which is one Martian year. (A year is the time it takes a planet to make a complete loop around the sun). Join us for a look back over the those 687 days of discovery: what we learned, what we saw, and what questions remained unanswered.

Doctor Atomic: The Opera Singer and the Physicist (Podcast)

Running Time:
1:17:34

How do opera singers sing loud enough to be heard over an orchestra? Can an opera singer's voice really break a wine glass? What's the difference between a baritone and a soprano? Discover the answers to these questions—and more!—in this presentation for families. Join physicist and composer Dr. Brian Holmes and San Francisco Opera Center Director Sheri Greenawald to explore how the art and science of singing combine in opera.

Science of Gardening: Polar Paradise (Clip)

Running Time:
00:04:12

McMurdo Station is the American staging area for Antarctic research. At the edge of Ross Island, off the coast of the continent, a small town of workeres feeds, houses, prepared, supplies, fuels, transports, and protects those who conduct field research throughout Antarctica and the surrounding waters. The community numbers 1,000 in the summer and 200 in the winter. And the community has a garden, from which they obtain their only fresh produce. Many love to visit this polar paradise.

Science of Gardening: Show 'n' Kale (Clip)

Running Time:
00:02:56

Sonoma Valley farmer Bob Cannard doesn't fight nature: he collaborates with it. The result is bountiful fields of healthy, beautiful plants, some of which end up in the kitchen at Alice Waters' Chez Panisse restaurant in Berkeley, California. Here Bob speaks eloquently about appreciating and respecting nature. As he says, "it's simple...it's all right there before you."
