- A synthetic-biology Mars-terraforming package was outlined: engineered Arthrospira platensis to reduce shipped food mass by 38 %, Cupriavidus necator to produce PHB feedstock for 3-D-printed habitats, and Synechocystis to synthesize acetaminophen on-demand; the 1976 NASA study “On the Habitability of Mars” and a 2015 Royal Society Interface paper were cited as foundational references.  
- Participants debated whether the first terraforming milestone should be a human-breathable atmosphere or simply a microbial biosphere, noting that extremophiles like Chroococcidiopsis and Carnobacterium spp. could blanket large areas within a year but that nitrogen and trace-element deficits in Martian regolith remain uncharacterized.  
- A “rainbow lens” or reflecting-satellite constellation was proposed to warm Mars above 0 °C, liberating subsurface ice to create an ocean that would accelerate subsequent biological seeding.  
- Lunar LOX/LH₂ fuel-depot economics were compared: Jeff Greason’s argument that Earth-Moon Lagrange depots enable 3–4 km/s hops with cheap, reusable tankers was weighed against the counter-argument that direct 4.3 km/s Earth-to-Mars trajectories render lunar detours superfluous.  
- Ralph Merkle’s claim that “privacy is meaningless” in the digital age was criticized; others suggested he doubts universal OPSEC competence rather than denying secrecy outright.  
- DIY BCI development was announced: FourFire ordered SparkFun Muscle Sensor v3 boards and promised open updates for an open brain-computer-interface project.  
- A curated index of 2015 iGEM projects relevant to open-source bioengineering was started at diyhpl.us/wiki/dna/projects/#igem-2015.  
- The RepRap Grand Prize funds held by Humanity+ were confirmed intact, raising expectations for upcoming open-source 3-D printing milestones.
