• Second-hand scientific equipment market: Russian researchers routinely acquire high-end lab hardware (HPLC, mass-spec) at steep discounts when institutions retire unsupported gear, often repairing and reselling it for profit.  
• Interplanetary data transport debate: Participants weighed Starlink-style satellite “chains” versus optical mesh networks, noting that resolving individual Mars-orbit satellites from Earth would demand extremely large telescopes and high-gain optical links.  
• LiFi vs. deep-space optical: LiFi is seen as a terrestrial consumer standard; space-based laser communication is considered decades overdue, with Mars-Earth links constrained by the planets appearing as point sources and the need for new frequency-band technologies.  
• Gravitational-wave communication speculation: IEEE survey paper was shared; discussion centered on whether modulated spinning masses could encode data, with rough “napkin math” estimating ~4 × 10³³ J per 100 Hz pulse—impractical but illustrative of energy bounds.  
• Latency-sensitive cryptography: MuSig aggregate signatures spanning Earth and Mars would require three round-trip light-time exchanges, highlighting protocol-level challenges for multi-planetary consensus.  
• PolygenX / Genotribe: RationalWiki entry was linked; participants argued the project does “good work” in genomics but criticized its focus on selection rather than active genetic engineering, while disputing the wiki’s framing as ideologically skewed.
