  2. Genomics, Computing, Economics & SocietyCourse plan Each student will participate in a class-wide project to provide decision-making tools for global/local technology development and deployment. Each will have a web page or wiki describing and updating their part of project going by the second class. Grades will be based on 1) participation (round robin) & project (cross-referenced pages) 2) critiques of each others components No prerequisites. But it is assumed that each of you brings some expertise to be integrated with the goals and talents of other team members. Each student should make this clear at the start of the project and update it as the course proceeds.

Should we construct from scratch? • Did life evolve using intelligent design? • When does human life begin? • Stem cells & therapeutic cloning? • Can we compare Apples & oranges? • Should we buy iron-lungs • or polio-vaccine research? • Do we invest in anti-terrorism • or anti-malaria?

  11. Yucky Leon Kass, chairs the US President's Council on Bioethics, opposes therapeutic cloning and stem cell research via 'yuck' reactions, which he terms 'the wisdom of repugnance' http://groups.msn.com/DebateCriticalThinkingandPhilosophy/killingimmortality.msnw Interracial-marriage: Perez v. Sharp, CA 1948, Loving v. Virginia, U.S. Supreme Court 1967 The Wisdom of Crowds by James Surowiecki 2004

  12. Tacky Not Wicked, Perhaps, but Tacky "First place goes to the regrettable tendency of some groups or institutions to bolster their stock by making extravagant claims in the media .. Refusal to share materials .. Anything that has the look of a publicity stunt or of self-interest --Donald Kennedy Science 297:1237 (2002) "Opinions are like genomes: Everyone has one. I want to show the world that we do not need to fear our genetic information but, rather, that it can be a powerful new tool" --J. Craig Venter Science 299: 1183 (2003) The Washington Post reported on Jun 18, 2005 that Chinese farmers, with the knowledge and support of government officials, used amantadine on chickens as long ago as the late 1990s. The report called the drug use a violation of international livestock guidelines.

  20. Energy & CO2 Sequestration Humans consume 2kW per person = 1010 kW. Sunlight hits the earth at 40,000 times that rate (70% ocean). CO2 370 ppm = 730 x1015 g globally, increase ~3 x1015 /yr. Ocean productivity = ~100 x1015 g CO2/yr … due to Autotrophs: 1026 Prochlorococcus cells globally (108 per liter) Sequestration v. respiration v. use: heterotrophs (Pelagibacter), phages, predators (Maxillopoda, Malacostraca, herring) 0.1 mm 0.1 m 6 cm http://www.gsfc.nasa.gov/gsfc/service/gallery/fact_sheets/earthsci/terra/earths_energy_balance.htm http://clear.eawag.ch/models/optionenE.html http://en.wikipedia.org/wiki/Copepod Morris et al.

  22. Responsible Conduct In Research "If scientists find that their discoveries have implications for some important aspect of public affairs, they have a responsibility to call attention to the public issues involved .. A good example is the response of biologists to the development of recombinant DNA technologies -- first calling for a temporary moratorium on the research and then helping to set up a regulatory mechanism to ensure its safety." http://www.aaes.org/membership/index.asp http://www.nap.edu/readingroom/books/obas/

  23. Safer biology via synthetic biology • Systems modeling • HiFi gene replacement • Inexpensive bio-weather-map custom biosensors • (airborne & medical fluids), • International bio-supply-chain licensing • (min research impact, max surveillance) • Metabolic dependencies prevent survival • outside of controlled environments • Multi-epitope vaccines & biosynthetic drugs. • Cells resistant to most existing viruses • via codon changes difficulty see: arep.med.harvard.edu/SBP

  24. Genome Analysis Policy • Insurance/employment: What probability & level of advantage can be hidden/examined? • Individual/group stigma • Choice, stem cells, cloning • Privacy & transparency NHGRI/DOE ELSI, Genetic Screening Study Group

  25. Anonymity, privacy, disclosure, identity

  26. "Open-source" Genome-Phenome Project • Are information-rich resources (e.g. facial imaging & • genome sequence) really anonymous? • What are the risks and benefits of "open-source"? • Prototypes for integrating biomedical data. • What level of training is needed to give informed consent on • open-ended studies? • Harvard Medical School IRB Human Subjects protocol • submitted 16-Sep-2004.

  28. CO2 100 ppmv increase 4x1013 kW of sunlight hits earth per year. We consume 2kW per person* 6x109 = 1010 kW. CO2 >370 ppm = 730 x1015 g globally, increase ~3 x1015 /yr.

  29. Models for education & decision-making Improve our ability to deal with: Uncertainty Complexity Quantitation Exceptions (collect and cherish) Comparisons of diverse entities Translation & integration Continuity over time

  30. Biophilia & Consilience Biophilia -- the connections that human beings subconsciously make with other living beings. (Cute animals, snake dreams, therapeutic greenery & natural sounds …) Consilience - Long-separated fields come together and create new insights; e.g. chemistry & genetics created the powerful new science of molecular biology. Is all human endeavor, from religious feeling to financial markets to fine arts, ripe for explaining by hard science? How might genomics & computational biology contribute? Kellert & Wilson 1993 The Biophilia Hypothesis. E. O. Wilson 1999 - Consilience: The Unity of Knowledge
