Origins: Astrobiology:  Life at the Extremes (Webcast)
Running Time:
00:35:56
Meet Breea Govenar, a biologist at Penn State University, as she speaks to us from aboard a research vessel from Wood's Hole Oceanographic Institute. She'll discuss life near deep-sea thermal vents in the Pacific Ocean. The Webcast also includes Dr. Alissa Arp, a biologist from San Francisco State University studying the tube worms that live around these very hot marine spots.

Origins: Astrobiology:  Life at High Temperatures (Webcast)
Running Time:
00:37:45
Jonathan Trent, Astrobiologist, NASA Ames Research Center studies "thermophiles," heat-loving microbes inhabiting places once thought too hostile for life, but analogous to environments that might be found on other planets. He discovered that some of these microbes make a protein that appears to stabilize their cell membranes (and may have applications for nanotechnology).

Origins: Astrobiology:  Life's Ingredients (Webcast)
Running Time:
00:43:30
Julia Child and physicist Philip Morrison once cooked up (and sampled) "primordial soup," a mixture of ingredients said to be the materials from which life sprang on Earth. How accurate is this notion? David Deamer studies how some molecules self-assemble into order, and has developed new theories about how life evolved from components on Earth. We’ll talk with him, do hands-on experiments, and watch vintage footage of Julia Child tasting the soup. Guests: David Deamer, Director, UC Berkeley SETI Program, and Karen Kalumuk, Exploratorium staff scientist.

Origins: Astrobiology:  Live from Licancabur Volcano in Chile (Webcast)
Running Time:
00:32:56
Nathalie Cabrol, Planetary Scientist, Principal Investigator at NASA Ames Research Center and the SETI Institute, looks for Mars analogs in extreme environments on Earth. She found one at the world’s highest lake at Chile’s Licancabur volcano, site of a unique analog to ancient Martian lakes. We chat with Dr. Cabrol as she investigates the life forms at Licancabur.

Origins: Astrobiology:  Is There Life Elsewhere? (Webcast)
Running Time:
00:58:53
How can a mathematical equation frame the question of life in the universe? We’ll talk with Frank Drake, one of the founders of the SETI Institute, about his famous equation and how it frames the search for signs of intelligent life in the universe.

Light and Landscape:  Charles Ross and Star Axis (Webcast)
Running Time:
00:10:19
Join the Exploratorium's Dr. Paul Doherty as he visits a "sculpture to observe the stars" in northern New Mexico, where the Sangre de Cristo Mountains meet the eastern plains. There artist Charles Ross is creating an art installation that is also a star observatory. This major earthwork has two main elements: the Star Tunnel, which allows you to walk through the entire history of the earth's changing alignment to our North Star, Polaris; and the Solar Pyramid, where one can visually experience an hour of the earth's rotation.

Return to Mars:  Red Planet: Up Close and Personal (Webcast)
Running Time:
00:37:05
We stayed up with Exploratorium scientist Ron Hipschman at the Lick Observatory in San Jose, California, for the best view we've had of Mars in a long, long time. At midnight on August 27, Earth and Mars passed closer to one another than they have in 60,000 years. Astronomers were on hand to tell us all about our nearest neighbor—its geography, orbit, and why both NASA and the European Space Agency have chosen this time to launch robotic missions to Mars.

Origins: Cold Spring Harbor:  Dr. Francis Collins (Webcast)
Running Time:
00:20:25
Dr. Francis Collins is the Director of the National Human Genome Research Institute, which is responsible for coordinating the government-sponsored effort to map and sequence the entire human genome, considered by many as one of the most important scientific undertakings of our time. Dr. Collins is a physician and geneticist whose own work led to the identification of the genes for cystic fibrosis, neurofibromatosis, and Huntington's disease. In this Webcast, Dr. Collins explains the different strategies for finding disease genes, the competition between public and private efforts to decode the human genome, and the next steps for the Human Genome Project, now that the first accurate gene maps have been created.
