- A Hacker News thread claiming that tDCS lowers IQ and racial prejudice sparked debate on whether reported IQ gains under stimulation are merely practice effects rather than true cognitive enhancement.  
- Participants compiled a short list of SNPs repeatedly linked to mathematical ability (rs11225308, rs363449, rs17278234, rs11154532, rs12199332, rs12613365, rs6588923, rs2300052, rs6947045, rs1215603) and noted that CHRM2 SNP rs324650 reportedly adds ~4.6 Performance-IQ points in a 667-person Dutch cohort.  
- The open “IQ related genes database” (iqdb.cbi.pku.edu.cn/snp.html) was examined and found to lack clear haplotype-to-intelligence annotations, underscoring the need for better open-access curation of intelligence-genetics data.  
- Key neuro-developmental and plasticity genes—NRCAM, Reelin, NT-3, and FADS1—were discussed for their roles in axon targeting, synaptogenesis, and potential cognitive phenotypes.  
- Kanzure proposed that the channel itself should design and run an open, rigorous project to discover and validate “interesting brain mutations,” given the fragmentation and political sensitivity of current intelligence-genetics research.  
- The “Super Awesome Micro Project” (superawesomemicroproject.com), a viral Lego car powered by compressed air, was critiqued for conflating structural novelty with energy autonomy; participants emphasized that compressed-gas actuation is a low-tech, general-purpose propulsion method rather than a sustainable transportation breakthrough.
