- The channel debated whether reality is a pre-existing mathematical object (modal realism) or merely a human-designed, utility-driven construct, framing the tension between objective mathematical truth and instrumentalist epistemology.  
- Participants criticized LessWrong’s “Friendly AI before Strong AI” stance as an engineering double-bind, arguing that competitive, open engineering is the missing prerequisite for any credible AI-safety strategy.  
- A concrete bio-hack proposal emerged: insert termite cellulase genes into black-soldier-fly larvae to up-cycle newspaper into low-cost chicken feed, illustrating the group’s habit of turning speculative biology into testable experiments.  
- Microfluidic DNA synthesis was dissected: the goal is an open-source <$10 k device that avoids photolithography, with 6-mer ligation chemistry floated as a potentially superior alternative to standard phosphoramidite synthesis, and electrowetting-on-dielectric (EWOD) droplet microfluidics discussed as a valve-free but high-voltage manipulation method.  
- An active open-access journal scraping project (ezproxy.py) is under development to liberate paywalled literature from ACS, Elsevier, and others; the modular Python tool is hosted at http://diyhpl.us/~bryan/irc/ezproxy.py and invites community plug-ins.  
- DIY Taq polymerase production is being refined: E. coli expression plus elastin-like polypeptide (ELP) tags enables low-cost, column-free purification, with plasmids and protocols shared in real time to cut reagent costs below commercial rates.  
- Hardware economics for PCR were analyzed: commercial OpenPCR at US $599 is deemed overpriced, <$100 DIY thermocyclers are feasible, and used lab units are often unreliable; historical “water-bath” manual PCR was cited as an ultra-low-budget fallback.  
- Brainhack 2012 (1–4 Sept, Max Planck Institute Leipzig) was announced as an unconference/hackathon for open neuroscience and interdisciplinary collaboration; details at http://www.cbs.mpg.de/events/workshops/brainhack.
