- The channel debated the “right” path to immortality: one faction insists on direct, skill-heavy engagement—mastering molecular biology and digesting the curated longevity literature at http://diyhpl.us/~bryan/papers2/longevity/—while another argues for earning capital to fund SENS-style research.  
- Functional-medicine critique: standard blood-test reference ranges are merely local-population percentiles, not objective health baselines, complicating rigorous self-quantification.  
- Active open-source DNA-synthesizer project: participants are testing reversible oligo-immobilization chemistries (biotin–streptavidin, photocleavable silanes, thermal release) to eliminate slow gel-extraction steps; ordered mesoporous carbon scaffolds (50 nm tunable pores) were offered as high-surface-area substrates.  
- Microfluidic mutation toolkit: beyond error-prone PCR, the group is exploring site-directed mutagenesis and programmable liquid-handling systems for targeted genome editing, with Raman spectroscopy proposed as a label-free readout of up-regulated proteins in engineered cells.  
- Brain–computer-interface hardware links: a 1992 paper on pneumatically implanting 100-electrode arrays at 8.3 m/s to reduce cortical trauma and a MEMS hydraulic actuator for precise electrode positioning were shared.  
- Open-source microarray/spotter resources: 2012 POSaM respin (http://www.jmu.edu/news/madisonscholar/2012POSaM-project.shtml), Protomatix systems-biology portfolio (http://www.protomatix.com/PORTFOLIO/SYSTEMSBIOLOGY/portfolio_isb.html), and cost data showing thermal-inkjet “ink” at >$3,000/L in 10 mL cartridges.  
- Ultra-low-cost STM/AFM initiative: a user outlined a concrete build plan using bulk PZT actuators (10 nm/V) or repurposed piezo buzzers, with sourcing tips and the DIY proposals list at http://diyhpl.us/wiki/projects/proposals/.  
- OpenPlant’s “Open Technology Week” (http://openplant.org/event-directory/open-technology-week/) announced as a venue for collaborative synthetic-biology hardware development.
