he public is invited to learn about viruses and microbiology as part of Alameda Free Library’s Social Science series at the Main Library, 1550 Oak St., this Saturday, Feb. 17, at 2 p.m. This is a free event open to all ages.

Viruses are infectious agents that exist in the twilight zone between the living and the non-living. Despite their tiny genomes and diminutive nature, viruses hold the power of life and death. They also contain remarkable molecular tools, some of which researchers have learned to harness to understand and control the fundamental powers of biology. Stanford’s Bob Siegel will shine light on the basic structure and function of viruses. He’ll also explore those features that distinguish viruses from the living organisms they commandeer.

To help make science accessible for everyone, Social Science and Wonderfest (a Bay Area nonprofit group) are partnering to bring world-class scientists from all disciplines to Alameda. Dr. Robert Siegel, MD PhD, is Professor of Microbiology & Immunology at Stanford University. He has won nearly a dozen awards for excellence in teaching.
