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. 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. See an 8 minute video of the planet Mars from the James Lick Observatory telescope! 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. 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. Dr. Carol Greider is a professor of molecular biology and genetics at Johns Hopkins University. She worked with molecular biologist Elizabeth Blackburn to discover the role of telomeres—segments of DNA that protect and stabilize the ends of chromosomes. Dr. Greider tells us about her work and shares her thoughts about the importance of mentors for women in science. Dr. Bruce Stillman is the Director of Cold Spring Harbor Laboratory, a position he inherited from James Watson in 1994. He continues his own research at the lab on DNA replication. In this program, Dr. Stillman describes the unique culture of science at CSHL, explores future directions of research, and tells us what he learned as an administrator for Dr. Watson. Learn how sparkling wine is made, what makes it different from still wine, and where all those little bubbles come from! We reveal how to open a bottle without touching the cork, as well as the best way to keep the bubbles in the bubbly. Join our special guests, Stanford chemistry professor Dick Zare, and French enologist Michel Salgues, winemaker at Roederer Estates in California, as we explore the science of tiny bubbles. Why does a turkey continue to cook after it is out of the oven? How can you be sure to thoroughly cook the dark meat without drying out the white meat? Is stuffing really a good idea? Join us as we talk turkey with food expert and author Harold McGee. Discover why temperature is critical, and investigate different cooking methods: roasting, deep frying, barbecuing, and smoking.
