- A 20-megapixel SentryScope linescan camera was described that builds images by sweeping a precisely controlled mirror to capture 10,240 vertical lines per second, offering an open-hardware path to ultra-high-resolution imaging.  
- nmz787 released open-source microfluidic CAD files for a tobacco-mesophyll-protoplast-fusion device modeled in ImplicitCAD (Haskell) and exported to STL, SVG, and G-code; the 152 MB STL at quality=2000 sparked debate over STL’s role as a “compiled binary” versus a stable distribution format.  
- A DIYbio protocol was outlined for fusing plant protoplasts in the microfluidic chip and then separating fused from unfused cells via a radial-flow filter that exploits the ~2× volume difference under simple column pressure differentials.  
- Participants deployed an InfluxDB + Grafana time-series stack on Google Cloud, documenting firewall rules, nginx permission pitfalls, and the undocumented DEFAULT_ROOT_PWD variable for first-time setup; performance tests showed earlier InfluxDB versions inserting only ~200 points/sec and taking minutes to query 3.2 M gold-futures records.  
- Cold exposure and non-shivering thermogenesis were analyzed through JCI papers showing that human brown adipose tissue (BAT) can be recruited by cold acclimation, improving metabolic health; evolutionary arguments were made for the co-ingestion of polyphenols in fruit and honey as a metabolic buffer against refined sugar.  
- A 2003 study on the oriental hornet (Vespa orientalis) was highlighted, revealing a 30-layer semiconductor cuticle that functions as a biological thermoelectric heat pump (≈100 mV photovoltaic side-effect) and suggesting similar nanostructures could enable infrared camouflage.  
- The absence of a fully open-source cellular baseband chip was attributed to closed GSM/3GPP protocols and tower-centric architecture; OpenBTS covers tower-side openness, while mesh projects like Serval bypass GSM entirely in favor of Wi-Fi.  
- iGEM metabolic-engineering projects were catalogued: HKUST’s glyoxylate-shunt pathway for human liver fat-to-glucose conversion, HUST-Innovators’ yeast omega-3 (DPA/DHA) production, and NJU-QIBEBT’s E. coli fatty-acid synthesis, with calls for a curated “metabolic fixes to steal from other species” repository.  
- A lunar and near-Earth-asteroid resource-extraction roadmap was sketched, proposing autonomous kinematic self-replicators that sinter regolith into roads and warehouses to bootstrap later high-value mining, referencing Freitas’s foundational self-replicating machinery work.
