• Vium’s “mouse cloud” remote vivarium was presented as a continuous, camera- and sensor-based monitoring platform for lab mice that could scale to human health surveillance, sparking debate on data ethics and consent.  
• A Hamamatsu C12880MA MEMS micro-spectrometer breakout (~$300) was identified as a compact, off-the-shelf component for DIY analytical chemistry and biosensing projects.  
• Ultra-low-error DNA synthesis strategies were dissected, centering on mismatch-recognition enzymes that selectively degrade or tag defective strands so only perfect molecules are amplified, and on real-time fluorescent quencher/fluorophore tags that report successful extension with >99.999 % efficiency.  
• Error-rate calculations showed that at 99 % per-base fidelity a 1 kbp construct yields only ~0.0043 % fully correct strands, yet micro-molar libraries (10¹⁰–10¹³ strands) still provide workable numbers; gigabase-scale constructs, however, remain impossible without radical improvements.  
• Participants circulated University of Alabama patent US9707535 and an associated PhD thesis on solid-phase oligonucleotide synthesis as foundational references for building integrated DNA synthesizer/sequencer devices.  
• “Write-optimized-to-read” chemistries were proposed for DNA storage, arguing that synthesis must be tightly coupled with rapid, low-cost verification—possibly via length discrimination rather than full sequencing—to achieve practical archival systems.  
• Physical limits of inkjet-style DNA printers were examined: current micro-stepping achieves ~200 nm positioning, but the group favored abandoning gantry systems in favor of electro-osmotic or electrophoretic microfluidics to shuttle DNA and proteins without mechanical motion.  
• Nucleosome geometry (146 bp wrapped + 80 bp linker ≈ 10 nm cube) was suggested as a practical addressing unit for ultra-dense DNA storage or computing substrates, while reel-to-reel substrate transport at 360–600 dpi (42 µm pitch) was proposed as a scalable alternative to nanometer-scale inkjet resolution.  
• DARPA announced an additional $300 million for “Post-Moore’s Readiness” research, underscoring sustained U.S. investment in beyond-CMOS computing paradigms.  
• The GP-Write consortium released two planning documents for public comment, and the open-source 3-D convolutional neural network repository astorfi/3D-convolutional-speaker-recognition was shared as an example of freely available audio-biometric research.
