Below you will find text from the executive summary of this white paper as well as comments noted during the MIT town hall on April 21, 2006. (Note that this is slightly different text than that used in the proposed resolutions in the white paper).
[Editorial note: Depending on the amount of discussion, individual resolutions should be spun out to their own pages.]

A.1 Insist That All Commercial Gene Synthesis Houses Adopt Current Best Practice Screening Procedures.
It is obvious that as gene synthesis continue to improve; the "dual purpose" of this technology will increase the attention of the biosecurity community. While most gene synthesis companies screen orders for dangerous sequences, a few do not. This gives both community members and outsiders access to feedstocks for both wild-type and genetically engineered bioweapons. Community members should stop doing business with any gene synthesis company that fails to implement current best-practice screening methods by January 1, 2007.
Items That Need Addressing Before Community-Wide Vote
[Editorial note: Likely to have errors and/or omissions. Please revise! Additional contributions welcome.]
- Should explicitly enumerate those areas which this resolution fails to address. [Laurie Zoloth]
- Gene assembly via synthesized oligos is a viable work-around to gene synthesis. A functional method for screening oligo synthesis orders has not yet been developed (“current best practices” = no action). This should be acknowledged to avoid creating a false sense of security.
- What fraction of synthesis orders is in the hands of this community?
- Best practices should involve safety & security screening at multiple stages including [Brian Baynes]
- Customer screening (e.g., rDNA protocol, select agent approval) (disputed)
- Customer verification (disputed)
- Sequence screening
- Sequence archiving
- There is no statement for possible procedures, consequences, clarification, or dispute resolution of failing a putative screen. -- Sri Kosuri 21:02, 23 April 2006 (EDT)
- Need community agreement, beyond default company models, for defining "best practices." For example, what will be method for developing and reaching agreement? Who speaks for the community? How are we to decide? What enforcement/dispute resolution methods is the community embracing? [Natalie Kuldell]
- Can we explicitly employ methods of testing compliance to the resolution? [John Cumbers]
- Historical examples/consequences of secondary boycotts should be considered [Ken Oye]
- Jan 1 2007 date is arbitrary; we need a specification of path forward up to SB3.0 at least [ Endy ]
- It is important to remember that the idea is not to design new "best practices" starting from a blank sheet of paper. (The industry has already given this problem much more thought than the average community member and, in any case, is not likely to heed calls to scrap existing systems and start over.) Rather, it is to close a looophole in which a few companies gain competitive advantage by failing to follow procedures that already exist and are followed by most of the industry. If people want to describe "best practices" in more detail, the way to do that is to find out empirically what most companies do today. [Maurer]
- Gene synthesis companies are most likely to be "checking" oligonucleotide orders against a pathogen genomic databases by probably BLASTing the oligonucleotide request. Since the score and the hit are dependent of the length of the sequence and the size of the database, a skilled biologist interested in developing a bioweapon could order sequences similar to the pathogen of interest but absent in the database. This issue must be recognized by the industry as one of the MAIN problems. [Willy Valdivia]
- In order to directly address the above issue, it is necesary to develop a RATIONAL, INTEGRATED and INTEROPERABLE genomic barcode databases covering key regions of lethal pathogens. This information could be accessible ONLY to certified gene synthesis companies and certified members of the scientific comunity (debate is necesary anout way to implement this). However, the generation of genomis signatures and barcodes still challenging considering that less than 3% of GeneBank contains pathogens of the A-C category sequence information [Willy Valdivia]
- The department of homeland security is already funding several efforts for the development of "barcodes-signatures". However, these efforts, fail to recognize the development of reverse eng. and computational technologies that generate possible variations which do not exist in nature, but have the same "lethality equivalence" and overcome filtering and screening databases. [Willy Valdivia]
- This proposal seems unlikely to work in practice given a) the global availability of commercial DNA synthesis; b) largely unregulated access to DNA synthesizers and reagents; and c) the relative ease of making homemade synthesizers [1]. More gene synthesis companies are likely to appear, and perhaps even inexpensive desktop devices, further complicating regulation. Would energies not be better directed towards low cost biodetection systems to sample genetic flow in the natural environment, which could help detect natural pathogens of all types, plus greatly expand the relatively small base of knowledge on microbial biosystems? [Andrew Hessel]
A.2 Create and Endorse New Watch-Lists To Improve Industry Screening Programs.
Improved watch-lists and software tools can make industry screening more accurate and efficient. Members should prepare the necessary lists and tools in time for Synthetic Biology 3.0.
- This is the place where members can exercise leadership by going beyond the "best practices" which already exist and asking what they should be. [Maurer]
Items That Need Addressing Before Community-Wide Vote
[Editorial note: Likely to have errors and/or omissions. Please revise! Additional contributions welcome.]
- Should outline procedures by which watch-lists and/or algorithms are developed. [Reshma Shetty, George Church]
- What will the watch lists be watching for? [ Endy ]
- How will the use of watch lists be enforced? How will watch lists work as synthesis moves to the benchtop? [Andrew Hessel]
B.1. Create a Confidential Hotline For Biosafety and Biosecurity Issues.
All experimenters contemplating “experiments of concern” should obtain independent expert advice before proceeding. The community should make such advice freely available to all experimenters, including non-members (e.g. hackers) who cannot otherwise obtain such advice from formal university, company, or NIH safety committees.
Items That Need Addressing Before Community-Wide Vote
[Editorial note: Likely to have errors and/or omissions. Please revise! Additional contributions welcome.]
- Redundancy with Recombinant DNA Advisory Committee or RAC. [Kris Jones Prather]
- Should be revised to focus on offering a RAC-like mechanism to the independent synthetic biology community outside of institutions with RACs. [Drew Endy]
B.2. Affirm Members’ Ethical Obligation to Investigate and Report Dangerous Behavior.
Members have an obligation to investigate and, if necessary, report dangerous behavior. Members should affirm this obligation by formal resolution at Synthetic Biology 2.0.
C. Create a Community-Wide Clearinghouse for Identifying and Tracking Potential Biosafety/Biosecurity Issues.
Members who notice potential biosecurity issues have an obligation to share them with the broader community. A central clearinghouse will help the community to identify, track, and if necessary respond to the biosafety/biosecurity implications of a changing technology.
D. Endorse Biosecurity/Biosafety R&D Priorities.
New technologies can potentially reduce current biosafety/biosecurity risks even further. Members should identify, endorse, and urge funding agencies to invest in priority technologies such as safe chasses and bar codes.
E. Additional resolutions
- Upon the uncontrolled physical release of a synthetic biological organism, community members should release all available sequence information and relevant system documentation. [Reshma Shetty]
- Upon construction/publishing/patenting of a biological organism (or system embedded within another organism), consider publishing a statement (or reaffirmation) of recommended (expected) safety and security level. Also, perhaps a central area to store information on novel organisms and those organisms whose safety or security level change. -- Sri Kosuri 02:10, 24 April 2006 (EDT)
- An ethics class should be mandatory for all synthetic biology curricula. Besides the "Don't be evil" portion, it could also include more grey areas, such as clinical trials and the issue of competing interests. Case studies would be useful. There's the University of Pennsylvania's human gene therapy experiment gone wrong. Salis 23:42, 23 April 2006 (EDT)
