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. Watch as the best teachers on the planet battle it out for the title of Iron Science Teacher. This special edition will pit east coast teachers from Columbia University against teachers from the Exploratorium's Teacher's Institute. In this zany competition teachers will have ten minutes to create a science activity from a "secret" ingredient: milk cartons! What if we did contact another intelligent life form in the universe? What should we say? What traits best represent our humanity? Douglas Vakoch, the SETI Institute’s Director of Interstellar Message Composition, is working with scientists, artists, linguists, composers, and others to imagine how to speak for our planet. 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. This week’s “secret” ingredient: cups!
