- A Science paper on “Reconfiguration of DNA molecular arrays driven by information relay” was shared as the primary source behind headlines about “switchable DNA machines for storing information.”  
- Discussion pivoted to ultra-high-throughput DNA synthesis: the idea of a “billion-valve printer” was revisited, with the observation that 1 billion micro-valves could address every possible 14-mer (4^14 ≈ 268 M) or, more practically, every 8-mer multiple times.  
- Inkjet-based oligo synthesis was debated; commercial print-head specs were collected (Fujifilm Samba 2048 nozzles @ 100 kHz, Xaar 5601 5600 nozzles, Kyocera KJ4, etc.) and contrasted with claims that “1 billion valves is not competitive,” though no detailed rebuttal was provided.  
- An alternative “oligo-library + inkjet” scheme was proposed: pre-synthesized short library fragments could be dispensed and ligated on-chip, potentially bypassing slow phosphoramidite chemistry cycles.  
- MEMS and thin-film piezo actuation were compared for droplet generation; references to 26 kHz DNA droplet ejection and 15 Gdrops/s aggregate throughput claims were noted.  
- Nanoneedle arrays for intracellular gene delivery (U. Penn MEMS work) were linked, but their lack of individual needle control was seen as a limitation.  
- Open-access policy debate: the article “We’ve failed: Pirate open access is winning and we must change our approach” (Green, Learned Publishing 2017) was circulated, prompting skepticism about “pirate black open” terminology.  
- CRISPR Therapeutics’ Q2-2017 institutional trading data (ARK, Vanguard, Wells Fargo, Credit Suisse) was posted as a snapshot of mainstream biotech investment flows.  
- A set of recent papers on encoding arbitrary information into non-natural polymers and foldamers was collected, including “Coding macromolecules…”, “Model-based design…”, and “Preparation of information-containing macromolecules by ligation of dyad-encoded oligomers.”
