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.

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.

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.

Produced by students from San Francisco's Aim High Program. Today they ask, how do our ears work? Can we communicate without words? How do whales communicate under water? Why don't bats slam into trees as they fly? Middle school students will interview Exploratorium Educator Ken Finn and Biologist Dr. Karen Kalumuck, plus special surprise guests!

Why do many things sound different underwater? How are echoes made? Can you feel or see sound? Join us as we delve into the mysteries of sound. This webcast will feature an Aim High student demonstrating how to make a membranophone; Exploratorium physicist Dr. Paul Doherty modeling sound with ringing aluminum rods, corrugated plastic whirlies, and a slinky; and Marco Jordan, lead educator in the Exploratorium's Outreach program, demonstrating sound science with a "whine" glass and a singing bowl.
