Extremophiles in Kamchatka: Kamchatka: Life in the Heart of a Volcano(Clip)
Running Time: 00:04:24
Two Russian scientists--geologist Gennady Karpov and microbiologist Elizaveta Bonch-Osmolovskaya--discuss the unique volcanic features of the Uzon Caldera, the life forms living in the hot springs there, and the important questions they raise.
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.
Origins: Astrobiology: Listening for the Long Term(Webcast)
Running Time: 00:43:41
Join us as we talk with Jill Tarter, Director of the Center for SETI Research and the inspiration behind Jody Foster's character in the movie Contact. Find out about the tools and technologies being developed for a multigenerational effort to search for life on other planets.
Origins: Astrobiology: Looking for Mars on Earth(Webcast)
Running Time: 00:32:24
Chris McKay, Planetary Scientist at the NASA Ames Research Center, has traveled the world seeking Mars-like environments. In the Dry Valleys of Antarctica—his favorite Mars analog on Earth—Dr. McKay discovered a kind of algae living inside rocks porous to light and water. He’ll show us some of these rocks and talk about the physical conditions required for life.
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).
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.
Osher Fellowship: A Live Conversation with World-Renowned Biologist/Conservationist E. O. Wil(Webcast)
Running Time: 00:33:44
In this archived program from 2003, join us for a conversation with Pulitzer-prize winning biologist E. O. Wilson, who introduced the term biodiversity to describe the interlocking dependence and diversity of organisms in sustaining life in biological communities.
