- Microfluidic ink-mixing was dismissed as impractical for ultra-high-resolution photo printing; participants favored proven LightJet laser-exposed photographic paper on cost and speed grounds.  
- DIY electroporation hardware was advanced through shared schematics (1.8–3.6 kV exponential-decay pulse circuits) and a PDF on electrofusion/electroporation generators from tuurvanbalen.com.  
- A Helicos employee (“single molecule”) posted to the diybio list, sparking discussion about potential lab access and collaboration with the open-source biology community.  
- Vacuum-survival research was reviewed: Bacillus subtilis reportedly grows at Mars-analog low pressures, while tardigrades endure near-vacuum without lysis, informing future extremophile experiments.  
- Open-source hardware proposals included repurposing CD/DVD/Blu-ray optical pickups to build a drum photo-printer capable of >14 k lines per inch resolution.  
- OpenWetWare governance issues were highlighted—new account approvals stalled and the DIYbio FAQ editing process described as awkward—while a 140 MB XML dump was circulated for archival purposes.  
- Quantified-Mind.com was introduced as a new web platform for cognitive self-tracking, though participants criticized its reliance on a marketing video instead of transparent test documentation.
