- A heated exchange explored how to publish open-source biology protocols: nmz787 proposed a wiki-plus-PDF pipeline that auto-generates polished reports from wiki templates, while kanzure insisted that a git-based, parseable backend must precede any UI, calling wikitext “morally and technically wrong.”  
- The 2010 DIY gene-gun project from Labitat/Hackteria was cited as evidence that wikis can already serve as effective open-protocol repositories, with links to the original Labitat wiki page and its PDF write-up circulated for reference.  
- nmz787 presented an open-hardware “smell-o-vision” prototype: 10–20 powdered spices in cotton-filled tubes, metered by $1 linear steppers and shift-register control, with air manifolds to mix scents before delivery to a helmet or face mask.  
- A Nature Communications paper on “Repopulation of decellularized mouse heart with human iPSC-derived cardiovascular progenitor cells” was shared via paperbot, underscoring ongoing interest in whole-organ bioengineering.  
- Halcyon Molecular appears to have quietly folded after burning part of its ~$20 M funding; an equipment liquidation sale was noted as evidence of the shutdown.  
- Trucoin (trucoinrt.com, invite-only) was introduced as a real-time Bitcoin meta-exchange that aggregates Mt.Gox, BTC-e, and Bitstamp, showing ~$10 spreads and enabling sub-minute arbitrage with USD settlement in four minutes; participants debated automating trades via PhantomJS because no official API exists.  
- Linus Pauling’s 1950 General Chemistry (Dover reprint ISBN 9780486656229) was praised for its clarity, alongside mention of a later “extensively revised” third edition.  
- The paper “Bandit Market Makers” (arXiv:1112.0076, mirrored at diyhpl.us) was recommended as background reading for designing algorithmic trading strategies.
