2. GtL Workshop B: Experimental Technology Development and Integration Tue at 2 PM Co-Chairs – George Church, Harvard Medical School Ham Smith, Institute for Biological Energy Alternatives As we attempt to understand, protect, and/or engineer environmental microbial communities, we need to ask what sorts of data would most benefit our models and how to obtain these cost- effectively. For this session let us answer what small (or large) technological step are we taking toward these specific challenges The framework for the discussions will be the following questions:  What are the most useful technologies for our tasks/goals now and for the future? What are the major technological gaps that will need to be addressed to reach the GTL goals? To what extent will the technologies be developed by others?  How can technologies best be used to complement each other and strengthen the resulting research/insights? How do we promote the kind of synergistic interactions among the practitioners? We would like to invite you to bring one viewgraph to share with the participants on your views about technologies needed to meet these challenges.

3. GtL Workshop B: Experimental Technology Development and Integration Tue at 2 PM Specific challenges: (1) Microscopic methods capable of tracing the chain of a small genome? (2) Quantitation of “all” peptide states (either in single cells or populations)? (3) Sequencing at Mbp per $? (4) Automated designed genome engineering? Discussions leaders: (1) Joachim Frank (Wadsworth Center, NY Dept of Health) on Cryo-Electron Microscopy (1) Hoi-Ying Holman (Berkeley Lab) on FTIR imaging (1) Steve Colson (PNNL) on optical imaging (2) Bob Hettich or Greg Hurst (ORNL) and Dick Smith (PNNL) on Mass spectrometry, (3) George Church (HMS) Polony sequencing (4) Ham Smith (IBEA) Genome Synthesis We would like to invite you to bring one viewgraph to share with the participants on your views about technologies needed to meet these challenges.

5. Improving Models & Measures Why model? “Killer Applications”: Share, Search, Merge, Check, Design

6. The issue is not speed, but integration. Cost per 99.99% bp : Including Reagents, Personnel, Equipment/5yr, Overhead/sq.m Sub-mm scale : 1  m = femtoliter (10 -15 ) Instruments $2-50K per CPU Why improve measurements? Human genomes (6 billion) 2 = 10 19 bp Immune & cancer genome changes >10 10 bp per time point RNA ends & splicing: in situ 10 12 bits/mm 3 Biodiversity: Environmental & lab evolution Compact storage 10 5 now to 10 17 bits/ mm 3 eventually & How ? ($1K per genome, 10 8 -10 13 bits/$ )

7. Projected costs determine when biosystems data overdetermination is feasible. In 1984, pre-HGP (  X, pBR322, etc.) 0.1bp/$, would have been $30B per human genome. In 2002, (de novo full vs. resequencing ) ABI/Perlegen/Lynx: $300M vs. $3M 10 3 bp/$ (4 log improvement) Other data I/O (e.g. video) 10 13 bits/$

8. Why single molecules? Integration from cells/genomes/RNAs to data Geometric constraints : Who’s “in cis” on a molecule, complex, or cell. e.g. DNA Haplotypes & RNA splice-forms

9. Polymerase colonies (Polonies) along a DNA or RNA molecule

12. $1K per diploid human sequence Input: Buccal cells, blood, or forensic samples. Output: Prioritized list of deviant bps (e.g. non-conservative). Raw data rate: 16 pixels/bp, 1Mpixel per 6sec/CPU = 24 CPU days. Amortization: 5 yr for camera/CPU/transport @ $50K total = $200 per 10 11 bp Overhead: $200 /sq ft/yr * 40 sq.ft (400 cu.ft) = $40 Reagents: At 20  m per (5  m) polony and 40 bp reads means 10000 cm 2 area, 800 ml of fluor dNTP, $100/mg = $40 5 ml PCR reactions = $200 Disposables: 500 slides = $50 Electricity: 2 kwatts 24hr*24days* 0.13$/kwatt-hr = $150 Labor for repair: 10% of instrument cost = $10 Labor for operation: Slide PCR, slide dips, scans, etc. = $20 R&D: Initially NIH grants (roughly 10%).

RS-3, 7, 8, 11, 14, 18, 19, 20 are still weakly expressed. Note that S1, S4, S7, S8, S20, L1, L4, L10 are known to repress their own translation (and are likely titrated by rRNA). Tian & Church
