Molecular biologist Elizabeth Blackburn--one of Time magazine's 100 "Most Influential People in the World" in 2007--made headlines in 2004 when she was dismissed from the President's Council on Bioethics after objecting to the council's call for a moratorium on stem cell research and protesting the suppression of relevant scientific evidence in its final report. But it is Blackburn's groundbreaking work on telomeric DNA, which launched the field of telomere research, that will have the more profound and long-lasting effect on science and society. In June, we hosted Catherine Brady who told the story of Elizabeth Blackburn's life and work and the emergence of a new field of scientific research on the specialized ends of chromosomes and the telomerase enzyme that extends them. On Monday, August 18th we welcome Elizabeth Blackburn herself to our Google San Francisco office. This event took place on August 18, 2008, as a part of the [email protected] series.
