- The Conboy lab’s new mouse study shows that replacing half of an old mouse’s plasma with saline + 5 % albumin (a “neutral age fluid”) reproduces the rejuvenating effects previously attributed to young-blood transfusions, improving muscle, liver, and neurogenesis markers.  
- Channel participants debated whether routine blood or plasma donation should already extend human lifespan if circulating “pro-aging factors” are removed, but noted that donor health-screening confounds observational data.  
- A ScienceNordic article was cited claiming Danish blood donors live longer, yet no comparable study exists specifically for plasma donors, highlighting a gap in longitudinal evidence.  
- Discussion turned to the feasibility of arcologies: docl asked why entire cities aren’t built as single megastructures; TMA argued that lack of economic demand and the governance vacuum that enabled Kowloon Walled City also limit scale.  
- L29Ah pointed out that Russian building codes mandating windows in apartments reflect cultural preferences for natural light and views, constraining fully enclosed urban designs.  
- nmz787 shared personal land-purchase plans (80 acres with outbuildings) driven by a desire for privacy, dark skies, and freedom from light and noise pollution, illustrating individual strategies for escaping density.  
- Links to NIH “Show Us Your Brains” contest winners and a poster on “Recording temporal data onto DNA with minutes resolution” were circulated, underscoring ongoing interest in neural interfacing and DNA-based data storage.
