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.

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. 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.

Dr. Walter Gilbert, a physicist who turned to molecular biology in 1960, won the Nobel prize in chemistry in 1980 for determining the base sequences of DNA. His recent research has concentrated on the structure of genes and the evolution of DNA sequences. In this Webcast, Dr Gilbert tells us how physicists have helped drive discoveries in molecular biology, and the relationship between private and university research efforts.

Dr. Sydney Brenner won the Nobel prize in physiology or medicine in 2002 for his work with the tiny nematode, C. elegans. Dr. Brenner recruited the one-millimeter worm in the early sixties as the ideal model organism to study cell differentiation and organ development. In this program, he describes how new model organisms are established for studying basic physiology, recounts his reaction to seeing Watson and Crick's DNA model for the first time, and offers advice to young scientists just starting out.

Dr. Jan Witkowski, Executive Director of the Banbury Center of Cold Spring Harbor, talks with us about the purpose of scientific meetings, about science as a social endeavor, and about some of the interesting people, events, and science stories that we can look forward to during the Biology of DNA meeting, which he coorganized with Dr. David Stewart, Director of Meetings and Courses at CSHL.
