Student Proposals from Ind. Studies
- Erich Baker Proposal: Media:Erich_Baker_proposal.docx This proposal deals with Phytochromes and Light Sensitive Channel Proteins
-I think the use of Phytochromes might be a good way to have either a continual stimulus that would repress/express certain genes that could be turned off and on depending on what we want them to do. There are other aspects of the research in this proposal that if not used outright, could be adapted to our continuing projects as either controls or feedback mechanisms. As for the proposed Salis RBS sites, I would like to see more information in the efficacy of the predicted RBS sequence. Possibly if we could use some of the C-Dog information based on a few known sequences to determine if the computer can predict those RBS's we know to be effective then we might be able to count on the calculator as a tool for our experimental design. -Caleb Carr

-This paper does a great job at highlighting the importance of socio-political legitimation in the funding of science. It seems that all new sciences must survive a period during which their only funding comes from public sources under the condition that those conducting it can make some kind of promises of future benefit to the society as a whole. After proving itself not only useful but also profitable, private money may then start flowing in, though by that point, the nature of that field may arguably have changed for better or worse. I think we would all agree that synthetic biology holds more promise than we can currently even imagine, both for advancing the public good and for providing opportunity for profit (in more than just pharmaceuticals), but it's not enough for us to believe it. Those of us who will someday pursue grants and/or private investments in synthetic biology must learn to speak not only the rational language of the science of synthetic biology but also the politically-driven language of the social benefits of synthetic biology, the socially conscious language of the ethics of synthetic biology, and the profit-driven language of the (future) business of synthetic biology (and possibly others). -Eddie Miles

Questions to Consider About Network Pathways
- Are they naturally occurring or synthetic?
- Do they involve screening or selection?
- Are they anabolic or catabolic?
- How many steps are in each pathway?
- How can they relate to cell fitness?
- What specific challenges would need to be addressed if we worked with the pathway?
