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.

Find out how yeast performs its biochemical transformation of a bit of flour and water into crusty, delicious bread. Explore the history of breadmaking around the world, and learn how bread has come to occupy such a central place in the cuisines of many nations. We'll bake some bread in our studio kitchen, play with yeast and glutens in our lab, and share recipes.

Look behind the scenes into the process of scientific research and the people who do it - in the tropical Central American country of Belize. In this series of Webcasts, we visited a field research station located in the remote Chiquibul forests of the mountains of Belize. See why science in the remote jungle of the Chaquibul forest of Belize can feel like an adventure movie.

The Near Infrared Camera and Multi-Object Spectrometer (NICMOS) will be brought back to life with the installation of the new experimental NICMOS cryo-cooler. The cryo-cooler updates the technology from that of an icebox to a modern refrigerator. We also talk to Keith Noll, head if the Hubble Heritage Project, which is responsible for bringing us those stunning pictures from deep space.

The Advanced Camera for Surveys (ACS) was successfully installed. In preparation for the installation of the NICMOS Cooling System tomorrow, the astronauts also installed the Electronics Support Module. We also talk with Massimo Stiavelli, a scientist at the Space Telescope Science Institute about his involvement with the ACS and the future Wide Field Planetary Camera 3 (WFPC3) scheduled to be installed during the next servicing mission in 2004.

00:34:08
Learn about the successful replacement of the Power Control Unit (PCU) and listen as we talk with Mark Clampin, part of the team that developed the Advanced Camera for Surveys scheduled for installation tonight.
