- Discussion of sub-10 ms keyboard latency: USB defaults to 125 Hz polling (8 ms), PS/2 to ~80 Hz (~12 ms); gaming keyboards can raise USB polling, but OS and graphics pipeline dominate perceived lag.  
- DIY electroporation / electrochemotherapy proposed for non-viral gene delivery: Lucas___ wants to build a low-cost pulse generator to transfect eukaryotic cells with GFP plasmid as proof-of-concept before human use.  
- Transcranial ultrasound stimulation project: kanzure is funding a hardware build (quoted by an external engineer) aimed at low-intensity brain stimulation and, at higher power, tumor ablation; literature archive at http://diyhpl.us/~bryan/papers2/neuro/ultrasound/  
- Implant culture critique: channel members dismiss “lame magnets,” suggest magnetoproteins as next-gen sensory augmentation, but caution against amateur viral vectors and emphasize tissue-culture validation first.  
- Open-source biology links shared: DIY insulin blog post (resilientvillage.blogspot.com), bristle-sensor EEG paper (brainsignals.de preprint), and Android app-install dataset (installs.csv) circulated for community analysis.
