• Nature reported the first 150-atom “programmable molecular robot” that can be chemically switched between states to perform stereodivergent synthesis, sparking debate on the definition of “programmable” and its implications for grey-goo scenarios.  
• Open Philanthropy granted $700 k to Genspace and NC State for a DIYbio biosafety fellowship, prompting criticism that the project conflates community labs with DIYbio and over-weights the influence of social-researcher Todd Kuiken.  
• A private “Society for the rescue of our elders” launched a Thousand-Oaks clinical trial of weekly rapamycin for aging reversal, while channel members argued that senolytic cocktails like dasatinib + quercetin are unlikely to benefit the already-frail.  
• nmz787 calculated that 6 GB/s DNA readout is theoretically achievable with only 0.13 mm² of 50 nm solid-state nanopores running at 450 nt/s each, but noted the absence of VLSI integration and commercial solid-state pores.  
• Bill Efcavitch revealed that column-based DNA phosphoramidite synthesis required ~200 man-years of development, establishing a benchmark for estimating resources needed for next-generation synthesizers.  
• Participants explored ink-jet “pulse-jet deposition” for DNA arrays, debating droplet-dispensing nozzle patents, pressure-transient failures, and non-contact deposition advantages for high-throughput manufacture.  
• A reel-to-reel “DNA tape” concept—an 8-track or Möbius-strip substrate continuously fed under inkjet heads—was proposed as a scalable alternative to fixed planar arrays, balancing throughput, modularity, and maintenance.  
• Le Chatelier’s principle was invoked to justify a ≥3× volumetric wash ratio per synthesis cycle for high oligo purity, while discussions explored targeted droplet washing with argon jets or hydrophilic-bump/hydrophobic-surface substrates to reduce solvent waste.  
• Yudkowsky proposed a bet-driven “AI’nt gonna happen” conference to elicit falsifiable short-term AI capability claims, specifically challenging skeptics who once claimed mouse-level AI was impossible within two years.
