Geneticist Mark Stoneking discusses a special type of genetic material called mitochondrial DNA gets passed directly from mother to child. Largely unchanged from generation to generation, this genetic material gives researchers a way to track populations back in time.

Watch as the best teachers on the planet battle it out for the title of Iron Science Teacher. In this zany competition teachers will have ten minutes to create a science activity. Tee off with this week’s “secret” ingredient-salt!

Dr. Eric Lander, a leading figure in the Human Genome Project and director of the Whitehead Institute Center for Genome Research, tells us about the recently completed mouse genome and how the study of other genomes gives key information about human genetics and evolution.

Dr. James Watson is the President of Cold Spring Harbor Laboratory and the co-discoverer of the double helix, for which he won a Nobel prize in physiology or medicine in 1962. Dr. Watson was also the first director of the Human Genome Project. He talks with us about early discoveries in molecular biology, the Human Genome Project, and what makes Cold Spring Harbor a unique scientific institution.

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. James Watson is the President of Cold Spring Harbor Laboratory and the codiscoverer of the double helix, for which he won a Nobel prize in physiology or medicine in 1962. Dr. Watson was also the first director of the Human Genome Project. He talks with us about early discoveries in molecular biology, the Human Genome Project, and what makes Cold Spring Harbor a unique scientific institution.

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.
