• A DIY open-source proton-precession magnetometer (PyPPM) was posted on Hackaday.io, offering a low-cost geophysics tool for field sensing and calibration.  
• Channel members explored antibody-based protein visualization via the new site visabl.com and confirmed that custom antibodies can be raised against virtually any target protein.  
• Practical applications of ultra-low-cost genome-scale DNA synthesis were debated: transferring entire metabolic pathways, correcting codon usage, creating variant libraries for drug discovery, and on-demand DNA vaccines or personalized retroviral gene-correction vectors.  
• Regulatory oversight of large-scale DNA synthesis was described as a “grey area” under DHS, likened to controls on precursor chemicals or GPS-guided missile components.  
• A curated archive of past iGEM projects was compiled, showcasing bacterial 3-D bioprinting controlled by holographic light, probiotic E. coli Nissle 1917, anti-caries Lactobacillus secreting S. mutans-blocking peptides, and stress-indicating fluorescent microbes.  
• Brain–computer-interface capabilities were clarified: current systems read via micro-electrode arrays and stimulate via TMS, ultrasound, or DBS, but “downloading” structured knowledge remains impossible due to bandwidth and neural-coding limits; human memory capacity is bounded at ~10^9 bits by thermodynamic constraints.  
• A comprehensive bibliography on low-intensity ultrasound neuromodulation was shared (http://diyhpl.us/~bryan/papers2/neuro/ultrasound/), noting that no channel member had yet experimented with the technique.  
• Electrostimulation for ejaculation/orgasm was discussed in depth, including the Prague hackerspace “multistim” device (~$1500), patent US3941136 for pelvic-nerve stimulation, and anecdotal evidence that 20 V DC across the pudendal nerve triggers ejaculation in under five minutes.  
• The Salmonella typhimurium Type-III secretion system (80 nm needle, 2 nm channel) was highlighted as a natural nanomachine and potential microfluidic flow generator when coated on micro-capillaries.
