• NASA NIAC “Orbiting Rainbows” paper outlines using optical tweezers on aerosol particles as a precursor technology for in-space additive manufacturing and large-scale orbital construction.  
• Participants explored the theoretical feasibility of a sub-handheld plutonium fission reactor (≈10 cm sphere, 6 kg Pu) that would stay sub-critical by relying on external neutron sources such as dense-plasma-focus devices or tritium boosting, and linked $10 Indian MKP-52 pulse capacitors as candidate drivers.  
• Millimeter-scale nuclear power options were surveyed: 1990s DOE micro-battery reports on tritium-based betavoltaic cells, newer powdered-radioisotope high-pressure gas-laser concepts, and a 1999 DOE tritium MEMS battery report circulated as reference.  
• DNA-origami staple cost has fallen 350× according to a Foresight Institute post; the accompanying ACS Nano paper and NSF nanomanufacturing grants were highlighted as immediate open-science opportunities.  
• GDB-11 and GDB-13 chemical-universe databases—complete enumerations of all stable ≤11- and ≤13-atom organic molecules—were introduced, with participants requesting the underlying synthetic-feasibility rules rather than raw SMILES strings.  
• A catalog of proposed molecular-machine components (acetylene hinges, ferrocene bearings, helicene springs, porphyrin gears, rotaxane joints, nanocars, nanotrains) sparked debate on whether engineered proteins offer nearer-term utility.  
• WikiHouse open-source CNC-cut housing was showcased via a time-lapse video, prompting criticism that the footage omits the crucial plywood-routing step and thus understates fabrication complexity.  
• Docker/Fig 1.0 release was announced as the final standalone version before integration into Docker core; new docker exec command and container root-escape vulnerabilities were discussed.  
• Ripple’s 2004 credit-network consensus (validator lists, no proof-of-work) was contrasted with Bitcoin, with participants analyzing its susceptibility to state coercion in light of the Argentina/NML sovereign-debt case.  
• GPU market dynamics post-Bitcoin-ASIC were speculated on: possible surplus of high-end AMD/NVIDIA cards and AMD’s limited strategic interest in mining due to its GPU-centric revenue model.
