Harry Noller has been doing molecular biology since before it was even called that, and he's been doing it very well. His work has helped illumine some of the fundamental processes on which all life (at least all earthly life) depends. He speaks about his fascinating career and research on today's show. We'll hear about his meetings with remarkable scientists, his own brush with Nobel laureate-hood and the dizzying intricacies of his pet research subject, the microscopic machines known as ribosomes.
