- g4k presented a full open-source design for a DIY flow cytometer, detailing laminar-flow cell alignment, microsecond capacitor timing, and single-cell droplet charging/sorting, with Shapiro’s hand-drawn “Practical Flow Cytometry” as the canonical reference.  
- Channel members debated a low-cost longevity “stack” combining 5–20 small molecules to push healthy human lifespan toward ~200 years, citing Michael Rose, Greg Fahy lectures, and a PNAS paper on GHRH antagonists extending mouse lifespan.  
- Microsoft Research’s “Biocoder” DSL for biology was criticized for poor object-oriented design; delinquentme had contacted authors William Thies and Vashnavi Ananth to discuss improvements.  
- Two 27C3 talks—“DIY Neurohacking” and “Hacking the Human Body”—were highlighted as forthcoming resources for biohacker techniques and safety protocols.  
- A Nature Chemical Biology paper on “Synthetic immunology to engineer human immunity” and the Seattle startup Adaptive TCR (commercializing immune-system profiling) were shared as key reading and commercial developments.  
- Ray Kurzweil’s 2010 self-assessment “How My Predictions Are Faring” was circulated and critiqued; participants argued that retinal-projection eyeglasses, full-immersion 3-D gaming, and virtual chat rooms have lagged behind his timelines, while NEC’s “Telescouter” retinal eyewear was noted as the closest real-world implementation.
