- Neuralink’s 2017 Wait-But-Why reveal was panned for lacking technical depth, while Kernel’s hippocampal memory implant is backed by peer-reviewed papers (Berger 2016 closed-loop ensemble stimulation and 2015 syringe-injectable electronics).  
- Facebook’s still-undefined “mind-reading” BCI and Google’s rumored entry were discussed as possible catalysts, with a preference voiced for optical over needle-based neural interfaces.  
- A 2016 Nature paper on heterochronic blood exchange and the Ambrosia young-blood trial (NCT02803554) were cited as concrete rejuvenation experiments, alongside GDF11 as a platelet-derived anti-aging factor and newly catalogued longevity SNPs (rs2069837, rs2440012) on diyhpluswiki.  
- GWAS skepticism: longevity hits such as APOE and methionine-synthase regulators were debated for biological plausibility and p-hacking risk, noting APOE’s dual Alzheimer’s/cardiovascular links.  
- DIY bio logistics: tips for shipping NaOH/Tris-HCl buffers for cheap sequencing cleanup, and a proposal to buy a used focused-ion-beam tool, mount it in a medical trailer, and avoid repeated recalibration.  
- Glowing-plant Kickstarter post-mortem: backers expected a luminous vascular plant but received only glowing moss, illustrating the gap between bio-art promises and deliverables.  
- nmz787_ arranged a $1 k farm-truck move for a large lab tool (likely SEM) despite calibration-drift risk, plans to partition his garage for dual SEM housing, and is considering quitting his day job to work on the project full-time.
