History and Ethics of BiotechnologyHSCI E137 Course website: http://isites.harvard.edu/k78554
Agenda for Jan 26 • The challenge of defining biotechnology • Its areas of application: agriculture and medicine • What ethical issues does biotech raise? • Syllabus and course requirements • In class reading: “The Birthmark”
Areas of application-- agriculture • Herbicide-resistant and pesticide-containing crops • Golden Rice (to remedy Vitamin A deficiency) • Corn genetically modified for ethanol production
Hybrid ethanol corn from DuPont (not genetically modified)
Areas of application-- agriculture • Herbicide-resistant and pesticide-containing crops • Golden Rice • Corn genetically modified for ethanol production • Transgenic trees-- low in lignin content
Eucalyptus trees genetically modified for low lignin content as well as higher-than- normal carbon dioxide absorptive capacity, Developed by Taiwan National Sci Council and NCSU (Biopact website) Low lignin poplars (NY Times)
Areas of application-- agriculture • Herbicide-resistant and pesticide-containing crops • Golden Rice • Corn genetically modified for ethanol production • Transgenic trees • Pharma-crops • Food from cloned animals

Areas of application--medicine • Gene therapy • Therapeutic cloning-- regenerative medicine

Areas of application--medicine • Gene therapy • Therapeutic cloning-- regenerative medicine • Genetic testing; pharmacogenomics
Some of the ethical issues: • The biotech industry and its subjects • Biobanks • Use of indigenous knowledge • Genetically modified crops

Ethical issues, continued: • Genes as intellectual property • Controlling genetically modified organisms • Screening/testing outpacing treatment • Treatment vs. enhancement • Playing God http://video.nytimes.com/video/2006/09/01/science/1194817115689/embryo-screening.html (the Kingsbury case, narrated by Amy Harmon)
